Description
Technical field
The present invention relates on the object of tabular or film like, form the technology of toner (toner) image, also relate to the technology of utilizing this toner image on object, to form Wiring pattern.
Background technology
In the past; As the method that on objects such as printed base plate, forms Wiring pattern; Use metal covering corrosion (subtractive) method, half to add (semiadditive) method, complete (fulladditive) method etc. of adding, use the metal covering etch promptly to form Wiring pattern with the cost that is lower than other two kinds of methods.
The metal covering etch has been utilized the photoresist technology; As this metal covering etch one of them near formula (proximity) Exposure mode in; For the object that on the insulativity base material, is bonded with Copper Foil (cu); On Copper Foil, form etchant resist,, etchant resist is made public via glass mask with the transmittance section corresponding or light shielding part or film masks with Wiring pattern with photonasty and corrosion stability.Then, through etchant resist is developed, thereby the part beyond the position that will be corresponding with the Wiring pattern of etchant resist remove, on Copper Foil, form the pattern (being corrosion-resisting pattern) of the etchant resist corresponding with Wiring pattern.Then,, the position that is exposed to outside the etchant resist of Copper Foil is removed,, thereby accomplish the forming process of copper Wiring pattern then through removing corrosion-resisting pattern through supplying with etching solution to object.
In addition, in utilizing the metal covering etch of screen printing technology, replace the mode that above-mentioned employing glass mask etc. makes public to etchant resist, and adopt corresponding with Wiring pattern edition on Copper Foil, to print corrosion-resisting pattern.
On the other hand, on etchant resist, describe method of patterning as not using mask etc., known have on etchant resist scan with the light beam of implementing spatial modulation, come directly to describe the mode (below be called " directly retouching mode ") of pattern with this.
In the flat 7-273428 communique (document 1) of TOHKEMY; On photosensitive drums, form the electrostatic latent image corresponding through xerography with corrosion-resisting pattern; Through the heat fusing toner this electrostatic latent image is developed form toner image after; The toner image that will pass through heating and become the state of dissolving is crimped on and carries out the heat fusing transfer printing on the processed member, and toner image is transferred on the Copper Foil that printed base plate is processed member as corrosion-resisting pattern.In document 1, can adopt the dry type heat fusing toner of particle diameter 7 μ m～15 μ m, perhaps the wet type heat fusing toner of particle diameter 1 μ m～2 μ m.
But; Utilize in the pattern plotters that carry out such as glass mask or version above-mentioned; Owing to need to make in advance with the Wiring pattern corresponding mask etc., and need be under the environment provided condition these masks etc. be preserved, thereby increased the manufacturing of mask etc. and the cost of preservation.In addition, owing under the situation that Wiring pattern changes, need new mask etc., thereby can't adapt to the limited-production needs of many kinds.In these methods,, therefore limited the raising of the fineness of the Wiring pattern that forms through etching in addition because there is the limit in the filmization of the etchant resist that on Copper Foil, forms.
Directly retouching in the mode, for example the set with small point (pixel) shows pattern, is the raster fashion of plots pattern with the point, for the height of realizing Wiring pattern becomes more meticulous, needs to improve the resolution (promptly dwindling area a little) of drawing apparatus.Therefore, when describing high meticulous pattern, increase owing to describing to count and to cause describing the time increase.In addition, identical with the pattern plotter that utilizes mask etc. with regard on Copper Foil, forming the etchant resist this point, therefore likewise, the height of Wiring pattern has the limit on becoming more meticulous with above-mentioned situation.In addition, because the light source of etchant resist illumination beam is needed powerful expensive light source, increase thereby cause describing cost.
Relative therewith; In the formation method of the corrosion-resisting pattern of document 1, make electrostatic latent image is developed and the toner image of the heat fusing toner that forms is transferred on the processed member, thereby do not use mask etc.; And on the surface of whole processed member, do not form etchant resist; But on processed member, form corrosion-resisting pattern, further adopt the less wet type heat fusing toner of particle diameter, thereby can promptly form high meticulous corrosion-resisting pattern.
But, in the formation method of the corrosion-resisting pattern of document 1, owing to be crimped onto on the processed member after making toner image become the heat fusing state, therefore existing because of dissolving or crimping damages the possibility of toner image, the height of corrosion-resisting pattern becomes more meticulous and has the limit.
On the other hand; As the technology that on tabular or film like object, forms toner image; In the past in duplicating machine or printer etc., as object, roller through electric conductivity or band or corona discharge are supplied with electric charge from the back side one side of object with insulators such as paper or film (perhaps character is near the material of insulator); At object with keep producing electric field between the photoreceptor of toner, thus make charged toner near and be transferred to the static printing on the object.
In addition; In JP special table 2002-527783 communique (document 2); Disclose such printing equipment: it is on the glass substrate time that the image of the liquid toner that forms on the photosensitive drums is transferred to sheet-like insulator; Between photosensitive drums and glass substrate, be provided with the gap, in this gap, be full of the carrier fluid of liquid toner.
But, in this static printing method, near the approaching transfer position of photosensitive drums and object, transfer electric field discharge (what is called is peeled off discharge) might take place in the space between photosensitive drums and the object.And; At object is that the paper that kind has under the situation of the object that is easy to partly the structure through electric charge; After the electric charge that supplies to the object back side one side passed from a surperficial side, electric charge moved on the toner on the photosensitive drums, caused making toner to disappear near the power of object; Perhaps, cause taking place toner and get back to transfer printing such on the photosensitive drums and come off because electric charge moves to the toner that is transferred on the object.Therefore; In the equipment that carries out static printing; In order to come off the Deformation control of the toner image that causes in the permissible range that is not regarded as the transfer printing defective because of peeling off discharge or transfer printing, must prevent to peel off recurring that discharge or transfer printing come off, the multiple technologies scheme has been proposed for this reason.
The static printing method can easily realize variable printed, and can realize high resolving power and high speed processing, therefore is widely used in various commercial units in recent years.In this case, the object of transfer printing toner is different from the such insulator of glass substrate of document 2, can consider the electric conductor of sheet metal or sheet metal etc.
But; Using under the situation of static printing method to the face that is transferred with electric conductivity of object; If peel off discharge between the part of object and the photosensitive drums, then the electric charge on the electric conductor can move and continues to produce and peel off discharge to the position that discharge is peeled off in generation.At this moment, as supply with the power supply of electric charge to object, if adopt constant voltage source, then can not alleviate and peel off the electric leakage that discharge causes, can continue to peel off discharge, distortion in a big way takes place and causes the transfer printing defective in toner image.In addition, if adopt constant-current supply, then can be owing to peeling off the caused electric leakage of discharge, the position transfer efficiency on every side that causes peeling off discharge reduces, and transfer printing defective in a big way also can take place.

In processing unit 3; Sense of rotation from charged device 32 along photosensitive drums 31 (being the CW Fig. 1) sub-image is formed portion 33, development section 34, clearer 35 and remove electrical equipment 36 be configured in photosensitive drums 31 around, development section 34 is connected with the toner supply portion (not shown) of supply as the liquid toner of developer solution.In addition, in image processing system 1, first current potential provide portion 4 also be positioned at photosensitive drums 31 around, be configured between development section 34 and the clearer 35.
It is corona charging mechanisms that first current potential provides portion 4; It produces ion through corona discharge; And make photoreceptor 312 charged through this ion being offered photoreceptor 312; In this embodiment, first current potential provides portion 4 to adopt grid net discharger (scorotron), to photoreceptor 312 first current potential is provided.In addition, the charged device 32 of processing unit 3 and first current potential provide portion 4 to make the charged corona charging mechanism of photoreceptor 312 through corona discharge.
Second current potential provides portion 5 to have two contactors 51, and contactor 51 has the brush (for example carbon brush or electric conductivity hairbrush) that is formed by conductive material.Each contactor 51 supports through not shown supporting member, directly contacts with the face that is transferred 91 with electric conductivity of object 9.Because the electrical ground connection of electrode of each contactor 51, so the also electrical ground connection of the face that is transferred 91 of object 9.In other words, the contactor 51 of portion 5 is provided, i.e. second current potential of earthing potential is provided to the face that is transferred 91 of object 9 through second current potential.
In image processing system 1, photosensitive drums 31 (a Z) side is moved that mechanism 2 drives and the face that is transferred 91 of the object 9 that moves with respect to photosensitive drums 31, provides the most approaching with the outer peripheral face of photosensitive drums 31 between portion 4 and the clearer 35 at first current potential.Then; Provide the portion 4 and second current potential to provide portion 5 that current potential is provided through first current potential; On photosensitive drums 31 and object 9 immediate positions; The transfer voltage of effect regulation is transferred to the toner image on the outer peripheral face of photosensitive drums 31 on the face that is transferred 91 of object 9 between the face that is transferred 91 of photosensitive drums 31 and object 9.In following explanation, the outer peripheral face of photosensitive drums 31 and the face that the is transferred 91 immediate positions of object 9 are called " transfer position ".Transfer position is with respect to processing unit 3 relatively-stationary positions.In image processing system 1; First current potential provides the portion 4 and second current potential to provide portion 5 to become toner image transfer printing portion, thereby they act on regulation between the face that is transferred 91 of photosensitive drums on the transfer position 31 and object 9 transfer voltage is transferred to toner image on the object 9.
As shown in Figure 1; Form in the system 100 at pattern; Make on the direction that object 9 moves in travel mechanism 2; With Etaching device 61, first cleaning device 62, image removes device 63 and second cleaning device 64 is configured between the photographic fixing portion 52 and object recoverer 205 of image processing system 1 successively, thus, image is removed device 63 and is configured between Etaching device 61 and the object recoverer 205.If pay close attention to a position on the object 9 that moves through travel mechanism 2, this position is installed to another by conveyance from a device through travel mechanism 2 successively.In other words, device 63 and the common object carrying mechanism of second cleaning device 64 are removed by image processing system 1, Etaching device 61, first cleaning device 62, image by the travel mechanism 2 that moves object 9.
Etaching device 61 has a plurality of throwers 611, and said a plurality of throwers 611 will be with iron chloride (FeCl
3) or cupric chloride (CuCl
2) wait the etching solution for principal ingredient to spray to the face that is transferred 91 of the object that is formed with toner image 9, first cleaning device 62 has a plurality of throwers 621, and said a plurality of throwers 621 spray the be transferred face 91 of cleaning fluids such as pure water to object 9.In addition; Image is removed device 63 and is had a plurality of throwers 631; Said a plurality of thrower 631 will be used for peeling off be transferred face 91 injections of the stripper of toner image to object 9 from object 9, and second cleaning device 64 and first cleaning device 62 likewise have a plurality of throwers 641 to the cleaning fluids such as the face that is transferred 91 injection pure water of object 9.
Below, the process that forms system's 100 formation Wiring patterns through pattern is described.Fig. 3 representes to form system 100 forms Wiring pattern on object 9 treatment scheme through pattern.In addition, step S11～S15 is the treatment scheme about photoreceptor 312 last branches among Fig. 3, but in fact is basically side by side to carry out these steps on whole photoreceptor 312.In addition, step S16-S20 is the treatment scheme about object 9 last branches, and in fact is basically side by side to carry out these steps on whole object 9.
In image processing system shown in Figure 21; At first; Making photosensitive drums 31 is the center with turning axle 310; CW in Fig. 2 begins rotation with certain rotational speed, and in travel mechanism 2, makes object supply unit 203 and object recoverer 205 respectively around rotation counterclockwise, thus make object 9 beginnings with certain speed to (+Y) direction moves.In processing unit 3; Rotation through photosensitive drums 31; With turning axle 310 is that the annular component of the cylinder drum type at center is a photosensitive drums 31 with respect to each peripheral structure of configuration on every side (promptly; Charged device 32, sub-image formation portion 33, development section 34, first current potential provide portion 4, clearer 35 and remove electrical equipment 36) circulate mobilely continuously along outer peripheral face, begin photoreceptor 312 to be handled through these peripheral structures.
In charged device 32, to the part of the photoreceptor 312 that arrives opposed position (below be called " object position ") electric charge is provided successively, the surface at object position is for example had+electricity (step S11) of 700V (volt).Move to the rayed position of sub-image formation portion 33 continuously at object position after charged.
The part (object position) that on photosensitive drums 31, forms electrostatic latent image to development section 34 relative to the position move.In development section 34, developer roll 341 is connected with developing bias power supply 343, provides+current potential of 500V through developing bias power supply 343.In addition; Through the bias voltage between developer roll 341 and the electrostatic latent image; Will be in liquid toner the wet type toner (that is, be scattered in the solvent of liquid toner and have the wet type toner of the electricity identical) of positively charged with the surface polarity of photoreceptor 312 offer electrostatic latent image (step S13).In this embodiment, it is the toner of (more preferably, below the above 0.5 μ m of 0.1 μ m) below the above 2 μ m of 0.1 μ m that the wet type toner preferably uses particle diameter.In addition, wet type toner principal ingredient is vinyl acetate (C
4H
6O
2).
Fig. 4 A to Fig. 4 C is for schematically showing the figure of Potential distribution that photoreceptor 312 surface of wet type toner 92 is provided through development section 34 (with reference to Fig. 2).In Fig. 4 C, draw the current potential on photoreceptor 312 surface at Fig. 4 A, solid line 81 is positioned at respect to photoreceptor 312 surfaces and just is made as with the situation of drum body 311 opposite sides with solid line 81.In addition, the size of the distance expression current potential of above-below direction between solid line 81 and photoreceptor 312 surfaces.
Shown in Fig. 4 A, in the object position on photoreceptor 312, the wet type toner 92 of the positively charged identical with the polarity on photoreceptor 312 surfaces only is attached to by sub-image and forms the position that portion 33 has reduced surface potential, thus electrostatic latent image is developed.That is, the object position on photoreceptor 312 outer peripheral faces forms the toner image before the transfer printing that is made up of wet type toner 92.In image processing system 1 shown in Figure 2, photosensitive drums 31 and drum rotation become the toner image maintaining part with motor, and its toner image before with transfer printing remains on the outer peripheral face of photoreceptor 312, and photoreceptor 312 circulations are moved.
In development section 34, (Z) squeegee (Squeegee roller) 342 of side (being the downstream that photosensitive drums 31 circulations are moved) strikes off unwanted liquid toner on the object position, thereby makes it turn back to development section 34 through being positioned at developer roll 341.Squeegee 342 is connected with power supply 344 with rubber rollers, is provided+current potential of 500V with power supply 344 by rubber rollers.In addition; Squeegee 342 rotates according to the CW among Fig. 1 and strikes off liquid toner; To remaining liquid toner on the photoreceptor 312 (promptly; To because of sub-image formation portion 33 has reduced the liquid toner that excessively provides on the position of surface potential, and be that background (backgroud) goes up the liquid toner of supplying with to the undiminished position of surface potential) reclaim.
Then; First current potential through the position before being configured in transfer position in the circulation of photosensitive drums 31 is moved provides portion 4; Above the toner image that develops at photoreceptor 312, provide polarity positive first current potential (step S14) identical with the charged polarity of wet type toner to the outer peripheral face of photoreceptor 312.Thus, shown in Fig. 4 B, the whole object position of photoreceptor 312 outer peripheral faces have with the degree identical or absolute value bigger current potential charged through charged device 32 (in this embodiment, be about+800V).In addition, on the object position, although the current potential of the adhering zone of wet type toner 92 is slightly different with the current potential of non-adhering zone, the potential difference (PD) of this degree for after the transfer printing of the wet type toner 92 stated do not have influence basically.In addition, this potential difference (PD) can provide portion 4 to provide the time of first current potential to eliminate by first current potential through prolonging.
Provide portion 4 to accomplish providing of first current potential through first current potential shown in Figure 2 after; The object position of photosensitive drums 31 arrives the face that the is transferred 91 immediate transfer position with object 9; On transfer position; The object position with the speed corresponding (that is, the speed of the tangential direction on the section vertical of photosensitive drums 31 outer peripheral faces) with turning axle 310 with the rotational speed of photosensitive drums 31 exactly to (+Y) direction moves, the same moved further of rotation of said object 9 and photosensitive drums 31.In addition, object 9 is moved mechanism 2 and drives, with transfer position on the identical speed in object position of photoreceptor 312, with identical with the traffic direction at object position (+Y) direction moves as moving direction.Thus, the position that on the position very near apart from transfer position, makes object 9 (the position relative with the object position) is with respect to the object position and relative fixed.
At this moment; Object 9 via transfer position (+Y) side and (Y) second current potential that disposes respectively of side portion 5 is provided two contactors, 51 electrical ground connection (in other words; Promptly provide portion 5 earthing potential to be provided to the face that is transferred 91 of object 9 through second current potential), the transfer voltage of effect regulation between the object position of the face that is transferred 91 of the object on the transfer position 9 and photoreceptor 312.That is, generation,, is used on the wet type toner 92 towards the masterpiece of the direction (that is the arrow direction of the Reference numeral 82 that, marks among Fig. 4 C) of the face that is transferred 91 of object 9 from photoreceptor 312 shown in Fig. 4 C towards the electric field that is transferred face 91 from the object position.Thus, be attached to the toner image of the positively charged on the object position of photoreceptor 312, be transferred to successively on the face that is transferred 91 of object 9 (step S15).
The object position of the photoreceptor 312 after the transfer printing of wet type toner continues to move to the position of clearer shown in Figure 2 35.In clearer 35, to the object position cleaning fluid is provided through injector nozzle 351, will not be transferred on the object 9 and to residue in the refuses such as wet type toner (below be called " residue toner ") at object position wetting.Thus, be bonded in the residue toner generation swelling (swelling) at object position, thereby the residue toner is with respect to the bounding force reduction of photoreceptor 312.
Then,, the object position of photoreceptor 312 wiped rub, make the residue toner be distributed in the cleaning fluid on the photoreceptor 312 through the sponge roller 352 of CW in Fig. 2 (that is, the direction identical) rotation with the sense of rotation of photosensitive drums 31.Be provided with injector nozzle 3521 sponge roller 352 with a forward side opposed position, object position, through to sponge roller 352 cleaning fluid being provided, thereby sponge roller 352 contacted with the state that contains cleaning fluid with the object position from injector nozzle 3521.Therefore, can prevent the cleaning fluid that sponge roller 352 absorbs on the photoreceptor 312, thereby the residue toner is distributed in the cleaning fluid on the photoreceptor 312 fully.
In addition, the position relative with the object position on sponge roller 352 is provided with in the opposite side of injector nozzle 3521 and attracts mouth 3522, can attract cleaning fluids from sponge roller 352 through attracting mouth 3522.Thus; Even owing to adhering on the sponge roller 352 under the situation that remains toner with the friction of photoreceptor 312; Also can this residue toner be removed from sponge roller 352 with cleaning fluid, all the time the position that contacts with the object position of sponge roller 352 remained the state of cleaning.
In clearer 35, for example be more than 1 second from the time of cleaning fluid till sponge roller 352 and object position rub is provided through injector nozzle 351.Thus, the residue abundant swelling of toner and be distributed in the cleaning fluid fully through the friction of sponge roller 352.
Then; Strike off the object position of photoreceptor 312 through sponge roller 353 according to right handed drying regime among Fig. 2; The residue toner that is dispersed in the cleaning fluid on the photoreceptor 312 is absorbed by sponge roller 353 with cleaning fluid, and is removed from photoreceptor 312 with the state that is attached to sponge roller 353.After cleaning fluid being provided, being attached to residue toner on the sponge roller 353 and being attracted mouth 3532 with cleaning fluid and attracting and remove from sponge roller 353 through injector nozzle 3531.Thus, the position that contacts with the object position on the sponge roller 353 can remain cleaning and dry status.
In clearer 35, because sponge roller 353,354 rotates with identical sense of rotation with photosensitive drums 31, sponge roller 353,354 is contacted fully with the residue toner, can reliably the residue toner be removed from photoreceptor 312 thus.In addition; When the residue toner that will adhere to sponge roller 353,354 is removed; Before attracting through attraction mouth 3532,3542; To sponge roller 353,354 cleaning fluid is provided, can be efficiently attracts the residue toners, and can prevent to remain toner and become the powdery toner because of attraction and disperse towards periphery from sponge roller 353,354.
Clean through 35 pairs of photoreceptor 312 surfaces of clearer photoreceptor 312 is mechanically restPosed after; Combination through having electric light and light filter or LED etc. remove electrical equipment 36 to object position irradiates light; Make photoreceptor 312 removed electricity, recover electrical original state.
As stated, the basic synchronization ground, each position on the photoreceptor 312 is carried out the processing of step S11～S15, can handle continuously each position of the photoreceptor 312 that arrives transfer position successively.Therefore; Whole toner image on photoreceptor 312 outer peripheral faces is transferred on the object 9 in transfer position; Through repeating this processing, finally can on the object that constitutes by a plurality of flexible circuit boards 9, form the toner image corresponding with the Wiring pattern of a plurality of flexible circuit boards.
In image processing system 1; Travel mechanism 2 make on the object 9 position that forms toner image from transfer position to (+Y) side shifting; And make its below through photographic fixing portion 52; Heat through 52 pairs of toner images that are transferred face 91 and are transferred on the face 91 of photographic fixing portion again, thereby make toner image be transferred photographic fixing formation corrosion-resisting pattern (step S16) on the face 91.
The position that travel mechanism 2 cleans the completion of object 9 is removed device 63 from first cleaning device 62 to image and is moved; Remove in the device 63 its supply stripper at image; Thereby make toner image on the object 9 (that is the corrosion-resisting pattern on the Wiring pattern that forms on the insulativity base material 93) peel off and remove (step S19) from Wiring pattern.Thus, formed the flexible circuit board of the copper Wiring pattern that has insulativity base material 93 and on insulativity base material 93, form.
The position of having peeled off toner image of object 9 is removed device 63 through travel mechanism 2 from image and is moved to second cleaning device 64, on second cleaning device 64, sprays pure water and comes cleaning object thing 9, thereby remove the stripper (step S20) on the object 9.Then, the position that the completion of object 9 is cleaned is moved mechanism 2 and takes out of from second cleaning device 64, and after carrying out drying through heating or air blast etc. as required, object recoverer 205 coilings that are moved mechanism 2 reclaim.Thus, formed the continuous circuit substrate thin plate of a plurality of flexible circuit boards.
As stated; In pattern formed system 100, the object 9 of the roller shape that the object supply unit 203 of travel mechanism 2 is kept was supplied to the transfer position of image processing system 1, and it is carried out the transfer printing and the photographic fixing of toner image; In addition; Remove device 63 through Etaching device 61 and image and carry out removing of etching and toner image, reclaimed by object recoverer 205 then, thereby can promptly form the circuit substrate thin plate that constitutes by a plurality of flexible circuit boards.
In image processing system 1; Through between the face that is transferred 91 of photosensitive drums 31 and object 9, acting on transfer voltage; Toner image is transferred on the object 9; Thereby the toner image that makes transfer printing photographic fixing on object 9 forms corrosion-resisting pattern, and said toner image is to be formed on the image on the outer peripheral face of photosensitive drums 31 through the wet type toner with corrosion stability.
Like this; Be electrostatically transferred on the object 9 through the toner image that will become corrosion-resisting pattern, thus with compare near formula (proximity) Exposure mode, can cut down the manufacturing and the retain costs of mask etc.; Thereby reduce the formation cost of corrosion-resisting pattern; Said proximity printing mode is meant, to the whole lip-deep photonasty etchant resist irradiates light that is formed on object and develop, forms the mode of corrosion-resisting pattern with this across mask etc.And because need be with the corrosion-resisting pattern corresponding mask etc., therefore for example under the situation of a spot of production of the flexible circuit board that carries out many kinds, can the multiple corrosion-resisting pattern of Cheap highly effective ground formation.
In addition, and the whole lip-deep photonasty etchant resist that is formed on object is carried out beam flying and (laser drawing) mode of directly retouching form corrosion-resisting pattern of developing is compared, can promptly form corrosion-resisting pattern.And; Because the light sensitivity of above-mentioned etchant resist is lower, therefore need powerful LASER Light Source for the exposure of carrying out etchant resist directly retouching in the mode, in image processing system 1 then because the light sensitivity of photoreceptor 312 is higher than above-mentioned etchant resist; Therefore; Compare with the LASER Light Source of directly retouching mode, the output power to the sub-image formation portion 33 that makes public with the corresponding pattern of corrosion-resisting pattern on the photoreceptor 312 is littler, thereby can reduce installation cost.
In the proximity printing mode or directly retouch in the mode; Be difficult to make etchant resist to be thinned to a certain degree above (for example thickness is below the 5 μ m); Therefore the height of the Wiring pattern that forms of the etching through subsequent handling becomes more meticulous and has the limit; In image processing system 1, make the formed toner image of wet type toner below the 2 less μ m of particle diameter become corrosion-resisting pattern, thereby can further realize the height of the formed Wiring pattern of etching of subsequent handling is become more meticulous.
In addition; In image processing system 1; Replace the proximity printing mode or directly retouched formation operation, exposure process and the developing procedure of etchant resist required in the mode; Can be only transfer printing and photographic fixing operation through toner image form corrosion-resisting pattern, form the required time of corrosion-resisting pattern thereby can shorten.Thus; Can prevent forming through etching in the process of Wiring pattern; Because of the formation operation of corrosion-resisting pattern needs the more time to become bottleneck than other operation; Can form system's 100 such triangular webs through pattern and carry out the series of processes relevant (that is stripping process of the formation operation of corrosion-resisting pattern, etching work procedure, corrosion-resisting pattern etc.) continuously with the formation of Wiring pattern.In pattern forms system 100, can be rapidly and form Wiring pattern accurately.
In addition; In image processing system 1; As mentioned above by static printing to object 9 transfer printing toner images; Therefore the situation that dissolves toner image with that kind such as heat fusing transfer printing when the transfer printing and carry out crimping is compared, and can reliably prevent toner image impaired distortion when transfer printing, can on object 9, form the toner image as corrosion-resisting pattern accurately.
As stated, in image processing system 1, through first current potential portion 4 is provided, the outer peripheral face of direction photoreceptor 312 provides first current potential with wet type toner identical polar from the toner image that forms through the wet type toner; Provide 91 electrical ground connection of the face that is transferred with electric conductivity that portion 5 makes object 9 (promptly through second current potential; To being transferred face 91 earthing potential is provided); At photoreceptor 312 be transferred between the face 91 and act on transfer voltage, toner image is transferred on the face that is transferred 91 of object 9 from photoreceptor 312.
As stated; In image processing system 1; Utilize the little wet type toner of particle diameter ratio dry toner to form toner image, thereby can first current potential be provided the outer peripheral face to photoreceptor 312, when object 9 provides earthing potential from the toner image top; To photoreceptor 312 first current potential is provided, thereby is used for the transfer voltage of toner image transfer printing.Thus; Even at photoreceptor 312 and be transferred in the space between the face 91 and peel off under the situation of discharge owing to transfer voltage; Also can the current potential at the position of peeling off discharge that is transferred face 91 be held at ground current potential, prevent to peel off discharge and recur.In addition; Can prevent the electric charge that offers object moves to toner; Thereby the transfer printing that causes comes off (that is, the toner on the photosensitive drums is not transferred to the phenomenon on the object, and the toner that perhaps temporarily is transferred on the object is got back to the phenomenon on the photosensitive drums).Consequently, can prevent to peel off the come off quality of the toner image that causes of discharge or transfer printing and reduce or damage, can be stably to the 91 transfer printing toner images of the face that is transferred with electric conductivity (that is, on object 9, forming toner image).
In processing unit 3, it is corona charging mechanisms that the ion that produces through corona discharge is provided to the outer peripheral face of photoreceptor 312 that first current potential provides portion 4, therefore is easy to photoreceptor 312 first current potential is provided.
In processing unit 3; Portion 33 forms electrostatic latent image on the outer peripheral face of photoreceptor 312 through sub-image formation; Use forms toner image through the xerography that 34 pairs of wet type toners of development section carry out latent electrostatic image developing, thereby can simplify the structure of processing unit 3 and image processing system 1.In addition, be the wet type toner below the 2 μ m through adopting particle diameter, thereby be easy to provide portion 4 to photoreceptor 312 first current potential to be provided reliably from the toner image top through first current potential.In addition, the thickness of the corrosion-resisting pattern of wet type toner formation is reduced, the further height of the Wiring pattern that in the etching of subsequent handling, forms is become more meticulous.In addition, be vinyl acetate owing to make wet type toner principal ingredient, thereby can heighten the corrosion stability of corrosion-resisting pattern.
In image processing system 1, first current potential and second current potential that first current potential provides the portion 4 and second current potential to provide portion 5 to be provided are not limited to above-mentioned current potential.For example, the face that is transferred 91 of object 9 needn't provide portion 5 electrical ground connection through second current potential, and as long as second current potential that provides portion 5 to provide to equate with earthing potential in fact through second current potential.Particularly; The absolute value of second current potential can be below 5% of absolute value that first current potential that portion 4 provides to photoreceptor 312 is provided through first current potential; At first current potential as stated be+situation of 800V under, the absolute value of first current potential that is then provided for-40V above+below the 40V.In this case, also can prevent to reduce or damage because of peeling off the come off quality of the toner image that causes of discharge or transfer printing, and can be stably to the 91 transfer printing toner images of the face that is transferred with electric conductivity.
Fig. 5 is the table that concerns between quality (transfer printing quality) and the transfer efficiency of expression first current potential and second current potential first current potential and the second current potential toner image when getting different value.As shown in Figure 5; If first current potential is the current potential that provides to photoreceptor 312 than charged device 32 (+700V) low+500V; Thereby even then make second current potential-200V～-change between the 400V cause first current potential and second current potential poor (promptly; Transfer voltage) changes, also can come off, cause to obtain good transfer printing quality owing to peeling off to discharge to produce discharge scenario or produce transfer printing.In addition, first current potential than charged device 32 under the high situation of current potential that photoreceptor 312 provides, if second current potential for example be-100V or-200V etc. like this and earthing potential (OV) gap bigger, then also can't obtain good transfer printing quality.
Relative therewith, if with first current potential be changed to charged device 32 to current potential that photoreceptor 312 provides (+700V) more than, and second current potential is earthing potential, then transfer printing quality is good.But, if first current potential for example be+900V like this with depart from potential difference (PD) that charged device 32 provides to photoreceptor 312 apart from bigger, then still can produce discharge scenario.Therefore in image processing system 1; When first current potential be charged device 32 to current potential that photoreceptor 312 provides (+700V) more than; And not when this potential difference (PD) is in the scope of big but be in+above deficiency+900V of 700V (be more preferably+700V is above+below the 850V); Making second current potential is earthing potential (current potential that perhaps equates with earthing potential in fact), can obtain good transfer printing quality.In addition, be+800V also can improve transfer efficiency through making first current potential.In addition; The preferable range of first current potential can change according to the kind of wet type toner, the material of photoreceptor 312, the various factorss such as radius-of-curvature of photosensitive drums 31; For example under the situation that the carried charge of wet type toner or photoreceptor 312 and wet type toner engaging force etc. change, when+400V degree, also can obtain good transfer printing quality.
Below, the pattern formation system of second embodiment of the invention is described.Fig. 6 is the figure that the pattern of expression second embodiment forms the image processing system 1a of system.In image processing system 1a, be provided with intermediate transfer portion 25 with intermediate transfer body 251, the toner image on the photosensitive drums 31 is transferred on the object 9 via intermediate transfer body 251 indirectly.Other structure is identical with image processing system 1 shown in Figure 2, the identical Reference numeral of mark in following explanation.
As shown in Figure 6, intermediate transfer body 251 forms the annular component of flat ribbon by dielectric substance, is set to roller 252a, 252b external.On a roller 252a, be connected with motor,, intermediate transfer body 251 contacted with toner image on the photosensitive drums 31, move along the outer peripheral face circulation simultaneously through CD-ROM drive motor.And, on another roller 252b, be connected with direct supply 253.In addition, compare with the image processing system 1 of Fig. 2, difference also is the place ahead that first current potential provides portion 4 to be arranged on the transfer position of intermediate transfer body 251, becomes reverse direction ((Y) direction) with the moving direction of intermediate transfer body 251 opposed objects 9.
In image processing system 1a; Through the current potential that provides to intermediate transfer body 251 via roller 252b, charged device 32 that will be through processing unit 3, sub-image formation portion 33, development section 34 etc. are transferred on the intermediate transfer body 251 at the toner image that forms on the photoreceptor 312.That is, contain the intermediate transfer portion 25 of intermediate transfer body 251 and the mechanism that 251 circulations of intermediate transfer body are moved, be on the outer peripheral face of intermediate transfer body 251, form indirectly and keep transfer printing before the toner image maintaining part of toner image.In addition; In image processing system 1a; In the outer peripheral face of intermediate transfer body 251 and the place ahead of object 9 immediate transfer position; Provide portion 4 to the outer peripheral face of middle transfer article 251 current potential of regulation to be provided equably through first current potential, thereby carry at the object position that has been provided current potential to object 9 from the toner image top.

Below, the image processing system of four embodiment of the invention is described.Figure 10 is the figure of the image processing system 1c of expression the 4th embodiment.The image processing system 1 (with reference to Fig. 1 and Fig. 2) of the pattern formation system 100 of the image processing system 1c and first embodiment likewise; Use xerography on the object of tabular or film like, to form toner image; In image processing system 1c; In Figure 10 of object 9b (+Z) interarea 91 of side (that is, being transferred face 91) is gone up the transfer printing toner, thus form toner image.In this embodiment, object 9b is the aluminium sheet of the about 1mm of thickness, and being transferred face 91, to have resistivity be 10
-6Ω cm above 10
3Electric conductivity below the Ω cm.Object 9b does not form Wiring pattern from the teeth outwards, and the toner that therefore is used to form toner image also needn't have corrosion stability.
Shown in figure 10, image processing system 1c has with the travel mechanism 2 and second current potential of image processing system as shown in Figure 21 provides the different 2b of travel mechanism of portion's 5 structures and second current potential that the 5a of portion is provided.Other structure then image processing system 1 with shown in Figure 2 is identical, in following explanation, marks identical Reference numeral for corresponding structure.
The 2b of travel mechanism has upper roll 201 and lower rollers 202; (+Z) side and (Z) the side clamping and keep object 9b from Figure 10 of upper roll 201 and lower rollers 202; Respectively according to CW among Figure 10 and rotation counterclockwise, object 9b along the moving direction that is transferred face 91 promptly (+Y) direction moves.
Second current potential provides the 5a of portion to have current potential roller 51a is provided; Said current potential provides roller 51a to utilize the flexible material (being conducting rubber in this embodiment) with electric conductivity to cover forming of central electrode on every side; Current potential provide roller 51a object 9b (Z) side can be that the center rotates according to the counter clockwise direction among Figure 10 with the turning axle parallel with directions X 510.In this embodiment, current potential provides the resistivity of roller 51a to be about 10
3Ω cm～10
6Ω cm.In the transfer position of image processing system 1c (promptly; The face that the is transferred 91 immediate positions of the outer peripheral face of photosensitive drums 31 and object 9b; Also be with respect to processing unit 3 relatively-stationary positions); Current potential provide roller 51a and electric conductivity object 9b (Z) interarea of side contacts, and provides roller 51a to the face that is transferred 91 of object 9b second current potential to be provided via current potential.In addition, provide roller 51a that object 9b is closely contacted with the photoreceptor 312 of photosensitive drums 31 across toner image on transfer position through current potential.In image processing system 1c, current potential provides roller 51a electrical ground connection, and through second current potential 5a of portion being provided is earthing potential to second current potential that object 9b provides.
Then, the process that forms the 1c of system formation Wiring pattern through pattern is described.Figure 11 is expression forms the treatment scheme of toner image on object 9b through image processing system 1c figure.In addition, the step S11 among the step S23 among Figure 11～S27 and Fig. 3～S15 likewise representes that in fact these steps are carried out overall optical body 312 to basic synchronization in time about the treatment scheme of photoreceptor 312 parts.Use image processing system 1c to form the flow process of toner image, the flow process that forms toner image with use image processing system 1 in first embodiment is basic identical, and same operation is carried out simple explanation.
In image processing system 1c shown in Figure 10; At first make photosensitive drums 31 be the center and begin rotation with certain rotational speed according to the CW among Figure 10 with turning axle 310, through the 2b of travel mechanism also make object 9b towards (+Y) direction begins to move (step S21, S22) with certain speed.Then; With first embodiment likewise; The rotation of the photosensitive drums 31 through processing unit 3, making with turning axle 310 is the photosensitive drums 31 as annular component of the cylinder drum type at center, with respect to each peripheral structure around being configured in (promptly; Charged device 32, sub-image formation portion 33, development section 34, first current potential provide portion 4, clearer 35 and remove electrical equipment 36) and circulate continuously along outer peripheral face mobile, thereby these peripheral structures begin photoreceptor 312 is handled.
In charged device 32, to the object position of the photoreceptor 312 that arrives opposed position electric charge is provided successively, the surface at object position is for example had+electricity (step S23) of 700V (volt).Move to the rayed position of sub-image formation portion 33 continuously at object position after charged.
In sub-image formation portion 33, shine the light that images form usefulness to photoreceptor 312 accordingly with the view data of the toner image that on the face that is transferred 91 of object 9b, forms.At light-struck position, surface potential is reduced to+100V, on photoreceptor 312 surfaces, forms the image (that is electrostatic latent image) (step S24) of CHARGE DISTRIBUTION.
The object position that has formed electrostatic latent image to development section 34 relative to the position move.In development section 34; Through between developer roll 341 and electrostatic latent image, providing+bias voltage of 500V current potential; Will be in liquid toner the wet type toner (that is, be dispersed in the solvent of liquid toner and have the wet type toner of the electricity identical) of positively charged with photoreceptor 312 surface polarities offer electrostatic latent image (step S25).Be endowed then ,+squeegee 342 of 500V current potential strikes off excess liquid toner on the object position, thereby makes it get back to development section 34.In this embodiment, with first embodiment likewise, use the wet type toner of (below the above 0.5 μ m of preferred 0.1 μ m) below the above 2 μ m of particle diameter 0.1 μ m.
In development section 34; With first embodiment likewise (with reference to Fig. 4 A); With the surperficial identical polar of photoreceptor 312 be the wet type toner of positively charged; In the object position on photoreceptor 312, only be attached to the position that has reduced surface potential through sub-image formation portion 33, make latent electrostatic image developing thus.That is, the object position on the outer peripheral face of photoreceptor 312 is through the toner image before the wet type toner formation transfer printing.In image processing system 1c shown in Figure 10, photosensitive drums 31 and drum rotation become toner image that on the outer peripheral face of photoreceptor 312, keeps before the transfer printing and the toner image maintaining part that photoreceptor 312 circulations are moved with motor.
Then, portion 4 is provided through first current potential, above the toner image that develops at photoreceptor 312, to photoreceptor 312 outer peripheral faces provide the charged polarity of polarity and wet type toner identical be positive first current potential (step S26).Thus, same (with reference to Fig. 4 B) with first embodiment, make whole photoreceptor 312 outer peripheral face object positions, have with the charged same degree of charged device 32 or absolute value more greatly current potential (in this embodiment, be about+800V).
After accomplishing the providing of first current potential, the object position of photosensitive drums 31 arrives transfer position.At this moment; (in other words object 9b provides the electrical ground connection of the 5a of portion via second current potential; Provide the 5a of portion earthing potential to be provided through second current potential to the face that is transferred 91 of object 9b), the transfer voltage of effect regulation between the object position of the face that is transferred 91 of the object 9b that is in transfer position and photoreceptor 312.That is, towards the electric field that is transferred face 91 (with reference to Fig. 4 C), effect is from the power of photoreceptor 312 towards the direction of the face that is transferred 91 of object 9b on the wet type toner from the object position in generation.Thus, be transferred to successively on the face that is transferred 91 of object 9b (step S27) at the toner image of the positively charged that adheres on the object position of photoreceptor 312.
Move to the position of clearer shown in Figure 10 35 continuously at object position behind the transfer printing wet type toner of photoreceptor 312; Remove the wet type toner residual (promptly through clearer 35 at the object position; Be not transferred to the wet type toner on the object 9b) etc. unwanted material; The surface of cleaning photoreceptor 312 makes photoreceptor 312 mechanically get back to original state.Thereby the electrical equipment 36 that removes of combination then through having electric light and light filter or LED etc. comes irradiates light photoreceptor 312 to be removed electricity, gets back to the original state of electricity.
As stated; The processing of step S23～S27 is that basic synchronization ground carries out for each position on the photoreceptor 312; Therefore handle continuously for the photoreceptor that arrives transfer position successively 312 each position, can make finally that whole toner image is transferred on the object 9b in transfer position on the outer peripheral face of photoreceptor 312.Then, stop the rotation of photosensitive drums 31 and stop the 2b of travel mechanism, finish to use the printing treatment of image processing system 1c, on the face that is transferred 91 of object 9b, form toner image (step S28, S29).In addition, in image processing system 1c, photosensitive drums 31 can rotate repeatedly and on a plurality of object 9b transfer printing toner image continuously.
As stated; In image processing system 1c; Same with first embodiment; First current potential provides portion 4 from the toner image top that utilizes the wet type toner and form to photoreceptor 312 outer peripheral faces first current potential with wet type toner same polarity, the 91 electrical ground connection of the face that is transferred with electric conductivity (that is, to being transferred face 91 earthing potential being provided) that second current potential provides the 5a of portion to make object 9b to be provided; At photoreceptor 312 and be transferred between the face 91 and act on transfer voltage, toner image is transferred on the face that is transferred 91 of object 9b from photoreceptor 312.
Like this; In image processing system 1c; Utilize the little wet type toner of particle diameter ratio dry toner to form toner image; Thereby can first current potential be provided the outer peripheral face to photoreceptor 312 from the toner image top,, act on the transfer voltage that is used for the transfer printing toner image through earthing potential being provided to object 9b and first current potential being provided to photoreceptor 312.Thus; Even at photoreceptor 312 be transferred in the space between the face 91 and produce under the situation of peeling off discharge owing to transfer voltage; Also can the current potential at the position of peeling off discharge that is transferred face 91 be remained in earthing potential, prevent to peel off recurring of discharge.In addition, thus the electric charge that can prevent to offer object moves to toner transfer printing come off (that is, the toner on the photosensitive drums is not transferred to the phenomenon on the object, and the toner that perhaps temporarily is transferred on the object is got back to the phenomenon on the photosensitive drums) takes place.Consequently, can prevent owing to peel off the come off quality of the toner image that causes of discharge or transfer printing and reduce or damage, thereby stably have transfer printing toner image on the face that is transferred 91 of electric conductivity (that is, on object 9b, forming toner image).
In processing unit 3, first current potential provide portion 4 be with the ion that takes place through corona discharge to the corona charging mechanism that the outer peripheral face of photoreceptor 312 provides, therefore be easy to first current potential is provided to photoreceptor 312.
In addition; In processing unit 3; Portion 33 forms electrostatic latent image on the outer peripheral face of photoreceptor 312 through sub-image formation; Use is through development section 34 and utilize the wet type toner to come the xerography of developing electrostatic latent image to form toner image, thereby can simplify the structure of processing unit 3 and image processing system 1c.In addition, through adopting the wet type toner below the particle diameter 2 μ m, can provide portion 4 to photoreceptor 312 first current potential to be provided through first current potential easily and reliably from the toner image top.
In image processing system 1c, first current potential and second current potential that first current potential provides the portion 4 and second current potential to provide the 5a of portion to be provided are not limited to above-mentioned current potential.For example, the face that is transferred 91 of object 9b need not provide the 5a of portion electrical ground connection through second current potential, and as long as second current potential that provides the 5a of portion to provide to equate with earthing potential in fact through second current potential.Particularly, the absolute value of second current potential can be below 5% of absolute value that first current potential that portion 4 provides to photoreceptor 312 is provided through first current potential, at first current potential as stated be+situation of 800V under, then be-40V is above+below the 40V.In this case, also can prevent to reduce or damage, stably to the 91 transfer printing toner images of the face that is transferred with electric conductivity by peeling off the come off quality of the toner image that causes of discharge or transfer printing.
In image processing system 1c; With first embodiment likewise (with reference to Fig. 5); Make first current potential+more than the 700V and deficiency+900V (more preferably+more than the 700V+below the 850V), making second current potential is earthing potential (current potential that perhaps equates with earthing potential in fact), thereby can obtain good transfer printing quality; Said first current potential charged device 32 to current potential that photoreceptor 312 provides (+700V) more than, and be in this potential difference (PD) in little scope.In addition, through making first current potential be+800V, thereby can improve transfer efficiency.In addition; The preferable range of first current potential can change according to the material of wet type toner kind or photoreceptor 312, the various factorss such as radius-of-curvature of photosensitive drums 31; The fluid-tight engagement power of the carried charge through changing the wet type toner, photoreceptor 312 and wet type toner etc. for example also can obtain good transfer printing quality under the situation of+400V.
Below, the image processing system of fifth embodiment of the invention is described.Figure 12 is the figure of the image processing system 1d of expression the 5th embodiment.Image processing system 1d has the essentially identical structure of image processing system 1a with second embodiment shown in Figure 6, and replaces the travel mechanism 2 among Fig. 6 and have the same 2a of travel mechanism of image processing system 1b to the 3rd embodiment shown in Figure 9 with Fig. 7.In this embodiment, with the 3rd embodiment likewise, on as the glass substrate of insulativity base material, be about 10 for having resistivity

3The object 9a as the ITO film of conductive layer of Ω cm carries out the formation of toner image.
In image processing system 1d; Through offer the current potential of intermediate transfer body 251 via roller 252b; Toner image is transferred on the intermediate transfer body 251, and the charged device 32 of said toner image through processing unit 3, sub-image formation portion 33, development section 34 etc. are formed on the photoreceptor 312.In addition; In the outer peripheral face of intermediate transfer body 251 and the place ahead of the immediate transfer position of object 9a; The current potential that provides portion 4 outer peripheral face of middle transfer article 251 roughly to be provided equably regulation from toner image top through first current potential, thus the object position that has been provided current potential carried towards object 9a.
In image processing system 1d, with image processing system 1b shown in Figure 7 likewise, the absorption of the objective table 21 through partly removing the 2a of travel mechanism, thus make the position of the idling seal position of object 9a can be towards the outer peripheral face warpage of intermediate transfer body 251.In addition; With image processing system 1a shown in Figure 6 likewise; The position of the transfer position of object 9a with the speed identical with the position of the transfer position of intermediate transfer body 251 in the same direction (promptly; The direction of (-Y)) moves, provide the contactor 51 of portion 5 earthing potential to be provided through second current potential to the face that is transferred 91 of object 9a.Thus; In transfer position; To the electric field force of wet type toner effect towards object 9a; And make object 9a towards intermediate transfer body 251 warpages through electrical affinity, when making intermediate transfer body 251 and object 9a closely contacts, the toner image on the intermediate transfer body 251 is transferred on the object 9a accurately.
More than embodiment of the present invention is illustrated, but the invention is not restricted to above-mentioned embodiment and can also carry out various changes.
For example, in the image processing system of the first, the 3rd and the 4th embodiment, can replace photosensitive drums 31 and the sensitization band of employing flat ribbon, in the image processing system of the second and the 5th embodiment, intermediate transfer body 251 can be a drum type.
It also can be other structure beyond the corona charging mechanism that first current potential provides portion 4.For example in the image processing system of the first, the 3rd and the 4th embodiment; Also can be to electric conductivity cavernous body power supply cylindraceous position; The electric conductivity cavernous body is contacted with the outer peripheral face of photoreceptor 312; Thereby the outer peripheral face from toner image top to photoreceptor 312 provides first current potential, and said electric conductivity cavernous body is to be the center towards the central shaft with turning axle 310 equidirectionals of photosensitive drums 31, to the sense of rotation rotation opposite with the sense of rotation of photosensitive drums 31.In addition, in the image processing system of the second and the 5th embodiment, also can to the outer peripheral face of intermediate transfer body 251 first current potential be provided through same electric conductivity cavernous body.
Through the electrostatic latent image that sub-image formation portion 33 forms, both can be that minus also can be an eurymeric.In addition, in processing unit 3, also can directly form electrostatic latent image through the ion flow on the photoreceptor 312.In development section 34; Can the liquid toner that contain electronegative wet type toner be provided to photoreceptor 312; In this case, through the charged device 32 and first current potential portion 4 being provided also is the negative potential of same polarity to the current potential that photoreceptor 312 (perhaps the intermediate transfer body 251) provides.
