Description
Technical field
The paste printing that the present invention relates to possess retainer and scraper is with scraper plate and use the paste printing equipment of this scraper plate, the manufacture method of wiring substrate.
Background technology
In the past, as the method that electronic component etc. is engaged with splicing ear on the wiring substrate, the known method that has based on solder bump.Usually, use soldering paste printing device being formed at being printed on a plurality of splicing ears on the face behind the printing soldering paste of wiring substrate, reflux and make the fusion of printing with paste layer, thereby form this kind solder bump.
Figure 10 represents to possess the existing example of paste printing with the soldering paste printing device 101 of scraper plate 104, and this paste printing has retainer 102 and scraper 103 with scraper plate 104.The order of printing soldering paste P1 by soldering paste printing device 101 on splicing ear 106 is as follows.
On the not shown workbench wiring substrate 107 is being remained under the horizontal state, at the overlay configuration mask 105 on the face that is printed of wiring substrate 107.Next, the scraper 103 of scraper plate 104 is contacted with the upper surface of mask 105, supply with soldering paste P1 to its direction of advance side.Under this state, scraper plate 104 is moved horizontally along the upper surface of mask 105.So, by scraper 103 soldering paste P1 is filled in the mask via, thereby on splicing ear 106, forms the printing with paste layer.In addition, when after mask 105 is broken away from, refluxing, printing with paste layer fusion and become solder bump.
Yet in this kind printing equipment 101, if soldering paste P1 is moved along prescribed direction, soldering paste P1 forms along the scraper plate Width and is rotated (roll extrusion) than the bar-shaped of length in the mode of rolling during printing.In this case, the paste printing improves, and the result forms the good print layer of shape unanimity easily.And beginning of roll extrusion need not increase the stroke of scraper plate more more, therefore can prevent the maximization of locking apparatus, and be favourable when printing on large-scale wiring substrate.
Yet, under the situation of the printing equipment 101 of existing example shown in Figure 10, owing to paste P1 is attached on the large tracts of land of direction of advance side of scraper plate 104, so roll extrusion may not be good, exist paste P1 on mask plate, not rotate sometimes and situation about directly moving with this state.Thereby because the deterioration of paste printing, the loading of soldering paste produces deviation, and the result is difficult to form the good print layer of shape unanimity.And even paste P1 is rotated, the beginning of roll extrusion also can postpone.
Based on above-mentioned situation, following soldering paste printing device had been proposed in the past: in the scraper plate of the structure in the maintenance recess that scraper is remained in retainer, by keeping out of the way recess, prevent that paste is attached to (for example with reference to patent documentation 1) on this side in the setting of the direction of advance side of its scraper leading section.
Patent documentation 1: Japanese kokai publication hei 11-20128 communique
Employed scraper plate is as broad as long simple in front surface and rear surface and parts with symmetrical section shape in the general printing equipment in the past, and employed scraper plate only has the recess of keeping out of the way in single side face in the printing equipment that patent documentation 1 is put down in writing, the parts that become relative complex and have the unsymmetrical section shape.Therefore, in the printing equipment of patent documentation 1 record, must make or buy special-purpose special-shaped scraper plate especially, in this, cost-effectivenes or versatility are poor.And, cause wearing and tearing or when aging owing to using, if general scraper plate in the past, then can front surface and upset back, rear surface use, but about the scraper plate of patent documentation 1 record, can't before and after the upset back use.This becomes the reason that cost-effectivenes descends.
Summary of the invention
The present invention proposes in view of above-mentioned problem, and its purpose is to provide a kind of paste printing with scraper plate, paste printing equipment, and it can can't harm the cost-effectivenes of scraper or versatility and the roll extrusion that can improve paste, thereby can form good printed layers.And, another object of the present invention is to provide a kind of method of wiring substrate of the good conductor portion that has the shape unanimity with the high finished product rate manufacturing.
And, as the method that is used to solve above-mentioned problem (method 1), relate to a kind of paste printing scraper plate, possess: retainer, it has the maintenance recess at leading section; With the scraper of being made by elastomer, it is kept by described maintenance recess, and has a part from the outstanding scraper protuberance of described maintenance recess; And, supplying with under the state of paste to the direction of advance side of described scraper, print described paste by moving along the face that is printed; Described paste printing is characterised in that with scraper plate the plane of the direction of advance side of described scraper protuberance or concave curved surface are that the plane or the concave curved surface of the direction of advance side of first inclined plane and described retainer leading section promptly disposes on second inclined plane continuously; And, connect and compose second leading section of front end on described second inclined plane and second imaginary plane of second rearward end that constitutes the rear end on described second inclined plane and be set to less than first leading section of the front end that connects and composes described first inclined plane and first imaginary plane of first rearward end of rear end that constitutes described first inclined plane with respect to the described angle of inclination that is printed face with respect to the described angle of inclination that is printed face.And, as the method that is used to solve above-mentioned problem (method 2), relate to a kind of paste printing scraper plate, possess: retainer, it has the maintenance recess at leading section; With the scraper of being made by elastomer, it is kept by described maintenance recess, and has a part from the outstanding scraper protuberance of described maintenance recess; And, supplying with under the state of paste to the direction of advance side of described scraper, print described paste by moving along the face that is printed; Described paste printing is characterised in that with scraper plate, the face of the direction of advance side of described scraper protuberance is that the face of the direction of advance side of first inclined plane and described retainer leading section promptly disposes on second inclined plane continuously, and described second inclined plane is set to less than described first inclined plane with respect to the described angle of inclination that is printed face with respect to the described angle of inclination that is printed face.
Therefore, in method 1,2 inventions of being put down in writing, if the time scraper plate is moved in printing, then paste at first along first inclined plane by sliding guidance, successfully to the second inclined plane side transmission of disposing continuously with first inclined plane, then along second inclined plane by sliding guidance.Since second inclined plane (or second imaginary plane) with respect to the angle of inclination that is printed face less than first inclined plane (or first imaginary plane) with respect to the angle of inclination that is printed face, therefore this moment paste flow direction change over the direction of easy roll extrusion.In other words, the actuating force of scraper plate is transformed into the revolving force of paste easily.Consequently, keep out of the way recess and also cause roll extrusion easily even on scraper, specially be not provided with, and the time started of roll extrusion also shifts to an earlier date.Therefore, the roll extrusion that can can't harm the cost-effectivenes of scraper or improve paste with versatility, thus can form good printed layers.
Also can be on retainer keeping out of the way recess near a side of cardinal extremity along what the scraper plate Width extended than second inclined plane.If this structure even will further be moved to the top on second inclined plane by the paste of sliding guidance to second inclined plane, also can stop it to move by keeping out of the way recess, the result can prevent that paste is attached to large-area situation.Therefore, can avoid the reason of roll extrusion decline is the resistance to sliding increase of paste.
At this, the material that forms retainer does not limit especially, and can select arbitrarily, but the preferred high material (materials such as metal, pottery, resin) of rigidity that uses than the scraper that constitutes by elastomers such as vulcanies.Its reason is that because when printing scraper plate is applied pressing force, ground reliably keeps scraper but need not misplace this moment.
Second inclined plane in the retainer also can be adhered to by paste and prevents that layer from covering.If this structure, then paste is difficult to be attached to second inclined plane, thereby can reduce the resistance to sliding of paste to second inclined plane.Therefore, successfully carry out sliding guidance, further improve roll extrusion by paste.And, when printing finishes, can remove the paste that is attached to second inclined plane easily.
Adhere to as paste and to prevent layer, limit especially, for example enumerate implement with the original surface state in second inclined plane mutually specific energy improve the processing of release property and form cover layer etc.Specifically, preferably second inclined plane is implemented the coating of fluoride resin etc.Perhaps also can reduce the original surface roughness in second inclined plane and carry out the processing of sliding surfaceization.
In addition, first inclined plane of scraper is preferably adhered to by paste and is prevented that layer from covering.Its reason is to be even surface because the surface of the scraper that is made of vulcanie etc. is original, is difficult to carry out the high coating of connecting airtight property, and from keeping the viewpoint of printing, the marginal portion of scraper is exposed.And because rubber comprises solvent and is out of shape, so coating peels off easily, and is from the viewpoint of durability, not preferred.In addition because, then cause cost to raise if change the scraper that has carried out the coating processing continually.
Paste adhere to prevent the layer preferably reach the surface of keeping out of the way recess, more particularly, be preferably formed to reach the form on the surface of keeping out of the way recess continuously from second inclined plane.If this structure even then the hypothesis paste is attached to the surface of keeping out of the way recess, also can be easily adhered to from paste and is prevented that layer from removing paste.
Paste adheres to and prevents that layer from preferably reaching a surface that keeps recess, more particularly, is preferably formed the form for the surface that reaches the maintenance recess from second inclined plane continuously.If this structure when then scraper is crooked by scraper plate is exerted pressure, is difficult for producing the gap between scraper and maintenance recess.And, even produce the gap paste is entered, also can easily remove afterwards attached to the lip-deep paste that keeps recess.
And, as the other method that is used to solve above-mentioned problem (method 3), relating to a kind of paste printing equipment, it possesses method 1 or 2 scraper plates of being put down in writing.Therefore,, can form following paste printing equipment according to the device that method 3 is put down in writing, the roll extrusion that it can can't harm the cost-effectivenes of scraper or improve paste with versatility, thus can form good printed layers.
In addition,, relate to a kind of manufacture method of wiring substrate as another method (method 4), the scraper plate printing paste that it is put down in writing by using method 1 or 2, and on substrate, form conductor portion.Therefore, the manufacture method according to method 4 is put down in writing owing to possess the scraper plate of above-mentioned excellence, therefore can improve the paste printing reliably, consequently can produce the wiring substrate of the good conductor portion with shape unanimity with high finished product rate.

This soldering paste printing device 21 possesses mask 26 in the top position of workbench 23.Mask 26 comprises mask plate 26a and the scraper carriage 26b that this mask plate 26a is supported.
This soldering paste printing device 21 also possesses scraper plate 22 and scraper plate driving mechanism 27 in the top position of workbench 23.Scraper plate 22 is supported by the lower surface of scraper plate driving mechanism 27, and is configured to the state that integral body leans forward.The scraper plate driving mechanism 27 of present embodiment is to be used to make left and right directions (Y direction) the mobile structure of scraper plate 22 along above-below direction (X-direction) and Fig. 1 of Fig. 1, comprises a pair of ball-screw (not shown) that has utilized motor and constitutes.Above-mentioned X-direction drive motor and Y direction drive motor are electrically connected with control computer 25 via motor drive circuit 25c respectively.Therefore, when exporting the control signal of regulation, drive each motor via motor drive circuit 25c from controlling computer 25.Consequently, scraper plate 22 is moved along X-direction and Y direction.In addition, scraper plate 22 is by pushing the upper surface of mask plate 26a with the pressure of regulation to the action of X-direction.And scraper plate 22 is by carrying out the filling printing of soldering paste P1 to the action of Y direction.In addition, in the present embodiment, the left end side of mask plate 26a shown in Figure 1 is the mobile top side of scraper plate 22, and the right-hand member side is the mobile end side of scraper plate 22.
This soldering paste printing device 21 possesses mask lifter 28, and this mask lifter 28 has pin 28a in the upper surface.Mould emptier is the structure that bar portion front end that mask lifter 28 is formed on the electronic cylinder that has utilized motor is equipped with pin 28a.This mask lifter 28 is configured in the below of the mobile top side of the scraper plate 22 in the mask 26, the front end of pin 28a all the time with the lower surface butt of plate carriage 26b.Aforementioned mask lifter 28 is that motor drive circuit 25d is electrically connected with control computer 25 via the pressing mechanism driving mechanism.Therefore, during from the control signal of control computer 25 output regulation, drive not shown motor in the electronic cylinder via described motor drive circuit 25d.Consequently, pin 28a is vertically outstanding, follows in this, and the scraper carriage 26b (mask 26 one-sided) that is in the mobile top side of scraper plate 22 is raised along the last direction (X-direction) of Fig. 1 with fixing speed.Consequently, the mask 26 of overlay configuration on the face that is printed 14 of wiring substrate 11 one-sided be printed face 14 separation number millimeter.
As shown in Figure 2, the scraper plate 22 of present embodiment is called as flat shape scraper plate, possesses retainer 31 and scraper 41.This retainer 31 forms by two metal partss 33,34 are overlapped, and has the maintenance recess 32 at its leading section (bottom among Fig. 1, Fig. 2) opening.Keep recess 32 to extend more longways along the Width of scraper plate.Metal parts 33,34 for example is made of rigidity such as aluminium or the stainless steel material higher than vulcanie.
The scraper 41 of present embodiment is the flat elastomer that is made of vulcanie.Scraper 41 is by keeping recess 32 to keep, and the part of its downside forms from the scraper protuberance 42 that keeps recess 32 to give prominence to.In addition, the setting that the overhang of scraper protuberance 42 can corresponding printing condition is suitably adjusted.
The face that is positioned at direction of advance 43 1 sides of scraper protuberance 42 is defined as first inclined plane 45, the face that is positioned at direction of advance 43 1 sides of the leading section of retainer 41 is defined as second inclined plane 35.In this retainer 41, dispose first inclined plane 45 and second inclined plane 35 continuously.Under the state that is provided with scraper plate 22, first inclined plane 45 and second inclined plane 35 all tilt about 45 degree～85 degree with respect to being printed face 14.In addition, under the state that mask plate 26a is overlapped, be printed face 14 and have the position relation parallel with mask plate 26a.And in the present embodiment, second inclined plane 35 is set to less than first inclined plane 45 with respect to the tilt angle theta 1 that is printed face 14 with respect to the tilt angle theta 2 that is printed face 14.More particularly, the tilt angle theta 2 on second inclined plane 35 is set to less than first inclined plane 45 with respect to the tilt angle theta 1 that is printed face 14 (being θ 2＜θ 1).The difference of the size of tilt angle theta 1, θ 2 is preferably about 5 degree～15 degree.This is because the angle of inclination difference is more little, just can't obtain desired effect more; When the angle of inclination difference was excessive, roll extrusion on the contrary might variation.
As shown in Figure 2, when the length on first inclined plane 45 during relatively from Width observation scraper plate 22 and the length on second inclined plane 35, second inclined plane 35 forms longly slightly.In addition, the length on the length on first inclined plane 45 and second inclined plane 35 also can be same degree.
In constituting the metal parts 34 of retainer 31,, be formed with along what the Width of scraper plate 22 extended and keep out of the way recess 36 than the position of second inclined plane 35 near base end sides (upside among Fig. 2).And, on the metal parts 34 that constitutes retainer 31, form paste by the coating of implementing fluoride resin and adhere to and prevent layer 37.Paste adheres to and prevents that layer from 37 not only integrally covering second inclined plane 35, but also reach the surface of keeping out of the way recess 36, the part of the surperficial 32a that keeps recess 32 and they are covered.
Next, illustrate that this soldering paste printing device 21 of use forms the order of flip-chip with solder bump 13 (conductor portion) on wiring substrate 11.
As shown in Figure 2, when printing, at first, making and being printed thing is that large-scale wiring substrate 11 is kept by maintenance recess 23a.Then, workbench 23 is risen and the face that is printed 14 of wiring substrate 11 is adjacent to mask plate 26a.At this moment, the face that is printed 14 of the inner surface of mask 26 and wiring substrate 11 has the position relation of almost parallel.And each through hole 26c of mask 26 has each the peristome 19 corresponding position relation with anti-solder flux 18.In addition, the pin 28a of mask lifter 28 still submerges in the mask lifter 28 at this moment.
Next, drive scraper plate driving mechanism 27 and scraper plate 22 is moved down, make the following ora terminalis of scraper 41 of scraper plate 22 and the mobile top side contacts of mask plate 26a.Supply with an amount of soldering paste P1 (Pb-Sn is that scolder, Sn-Ag are that scolder, Sn-Ag-Cu scolder, Sn-Zn are well known materials such as scolder) by not shown paste feed unit to the position of the direction of advance side (being the right side among Fig. 2) of upper surface and the scraper plate 22 of mask plate 26a.
And, on the basis of suitably setting translational speed and exerting pressure, scraper plate 22 is moved along mask face direction and the face direction (specifically from the left side of Fig. 2 towards the right side) that is printed face 14.Thus, soldering paste P1 is filled in through hole 26c and the peristome 19, forms the printing with paste layer (with reference to Fig. 3) of the height suitable with the thickness of mask 26.This printing with paste layer is the printed layers of flip-chip afterwards to be formed with solder bump 13.
Next, drive mask lifter 24 at official hour, outstanding upward by making pin 28a, and mask 26 is broken away from.So the printing with paste layer is extracted from the through hole 26c of mask 26.
Therefore, according to present embodiment, can access following effect.
(1) under the situation of the soldering paste printing device 11 of present embodiment, if when printing, scraper plate 22 is moved, then soldering paste P1 at first along first inclined plane 45 by sliding guidance, thereby successfully to second inclined plane, the 35 1 side transmission of disposing continuously with first inclined plane 45, then along second inclined plane 35 by sliding guidance.Since second inclined plane 35 with respect to the tilt angle theta 2 that is printed face 14 less than first inclined plane 45 with respect to the tilt angle theta 1 that is printed face 14, therefore, this moment, the flow direction of soldering paste P1 was changed into the direction (with reference to the arrow among Fig. 2) of easy roll extrusion.In other words, will be transformed into the revolving force of soldering paste P1 to the actuating force of the direction of advance 43 of scraper plate 22 easily.Consequently, need not be as prior art on scraper 41, specially be provided with and keep out of the way recess and also cause roll extrusion easily, and the roll extrusion time started also shifts to an earlier date.Therefore, can use commercially available simple and scraper 41 with symmetrical section shape, the roll extrusion that can can't harm the cost-effectivenes of scraper 41 or improve paste P1 with versatility, thus can form good printing with paste layer.And the soldering paste printing device that possesses the scraper plate 22 of the excellent structure of this kind by use forms the printing with paste layer, can produce the wiring substrate 11 of the good conductor portion with shape unanimity with high finished product rate.
(2) in the present embodiment, owing in retainer 32, form than second inclined plane 35 and more keep out of the way recess 36 to what cardinal extremity one side was extended, even therefore will will further be moved to the top on second inclined plane 35, also can stop it to move by keeping out of the way recess 36 by the soldering paste P1 of sliding guidance to second inclined plane 35.Consequently, can prevent that soldering paste P1 is attached to large-area situation.Therefore, can avoid the reason of roll extrusion decline is the resistance to sliding increase of soldering paste P1.
(3) in the present embodiment, prevent that layer 36 from covering, so soldering paste P1 is difficult to be attached to second inclined plane 35, thereby can reduces the resistance to sliding of soldering paste P1 second inclined plane 35 because second inclined plane 35 in the retainer 31 is adhered to by paste.Therefore, more successfully sliding guidance soldering paste P1 further improves roll extrusion.And, when printing finishes, can remove the soldering paste P1 that is attached to second inclined plane 35 easily, thereby improve maintainability.
In addition, embodiments of the present invention also can change as described below.
In the above-described embodiment, making the paste by scraper plate 22 printings is soldering paste P1, but is not limited thereto.For example, also can adopt the metal paste that comprises conductive metal except that scolder, in addition, can also irrespectively comprise the paste etc. of any particulate with conductivity by scraper plate of the present invention 22 printings.And paste is not limited to use when the manufacturing of wiring substrate 11, also can use when the product beyond making wiring substrate 11.
