Description
Technical field
The present invention relates to a kind of combination silk screen plates used in the silk-screen printing of contact.
Background technology
In silk-screen printing, (Japanese is printed in order to cope with precision traverse：Off ァ イ Application ラ イ Application prints) and promote silk screen
Graph thinning, and in order to which use intensity is low and the silk screen of high price and printing is directly adhered to the direct sticking structure of frame with silk screen
It compares, the silk screen plate of composite structure becomes mainstream.Combination silk screen plate is will be fixed around printing silk screen via supporting mass
In the component of frame.
In the case where combining silk screen plate, due to absorbing load of pressure when printing to printing silk screen by supporting mass
Therefore lotus generally uses and uses silk screen more to possess elastic synthetic fibers silk screen as supporting mass (for example, patent is literary than printing
It offers 1).
However, because of the miniaturization of electronic component in recent years, multifunction so that the line width of circuit becomes fine, with more
The requirement that high printing coordinate precision carries out silk-screen printing is increased.For example, in the multi-layer products such as laminated ceramic capacitor, it is desirable that
± 20 μm of printing precisions below.Thus, in the combination silk screen for having used the supporting mass being made of existing synthetic fibers silk screen
In plate, there is the printing precision this problem that cannot achieve as target.
In patent document 2, a kind of combination silk screen plate is disclosed, using in the wire mesh screens purpose for having woven stainless steel fibre
Braiding surface is covered with the hard silk screen (Japanese of plated film：リ ジ ダ イ ズ De ス ク リ ー Application) be used as printing silk screen, and use than
Printing is thick with silk screen and is covered with the hard of plated film on the wire mesh screens purpose knit unit surface for having woven the big stainless steel fibre of line footpath
Silk screen is as supporting mass silk screen.In this case, since the stretching of the draw ratio synthetic fibers silk screen of supporting mass silk screen is small, because
This, can realize the raising of printing precision.
However, due to the use of stainless steel sieve mesh as supporting mass, therefore, in the pressure using scraper plate and deformed position
The restoration of coordinate is bad, to which printed pattern is easy to distort.As a result, it is difficult to obtain desired printing precision.In addition, branch
It is sieve mesh structure that it is same as printing silk screen, which to hold body, and needs to implement plating, therefore expensive.In addition to this, thickener (print
Brush ink) a part can enter supporting mass silk screen seam (Japanese：Mesh), there is also above-mentioned thickeners to be made to press quality
At dysgenic possibility.

Invention content
The purpose of the present invention is to provide a kind of combination silk screen plates, are suitable for contact with printing, can carry out high accuracy prints, and
Durability is high.
Before being illustrated to meaning of the present invention, contact printing is illustrated first.Silk-screen printing generally has
Contactless (Japanese：オ Off U Application タ Network ト modes) and contact.It is so-called contactless, it is that printed object is positioned in by water
On the print station of flat bearing, and to be spaced apart the printing silk of the state to silk screen plate in gap between the surface of above-mentioned printed object
Net is kept, and thickener is supplied on printing silk screen, and scraper plate is supported on one side and is pressed on printing silk screen, makes scraper plate on one side
It moves horizontally, to make printing be bent with silk screen, the pattern will be formed in printing silk screen is needed on printed object.
However, in contactless printing process, when each scraper printing be stretched downwards with silk screen, utilize simultaneously
Frictional resistance between scraper plate, and printing is made also to be stretched in the in-plane direction with silk screen.It is asked as follows as a result, existing
Topic, that is, the printing of the pattern being formed on the surface of printed object, which deviates, to be easy to become larger or the durability of printing silk screen
It is easy to decline.
On the other hand, contact is by being kept on the surface of printed object and printing in advance almost in contact with shape with silk screen
(still, 0) the distance between printing silk screen and printed object are not limited to state, and scraper plate is made to move horizontally, to make printing
It is hardly bent in a thickness direction with silk screen, the pattern that just can will be formed in printing silk screen is needed on printed object.At this
In the printing process of kind contact, compared with contactless, since printing is small with the stretching of silk screen in a thickness direction,
It is such to have the advantages that printing offset and shape deterioration become smaller.
As recorded in patent document 3,4, a kind of printing process of contact is also developed, is in using with section
The print station of the peripheral surface of arc-shaped, and make surface one side and the printing silk screen of the printed object being adsorbed on the peripheral surface
The back side and scraper plate the corresponding position contact of front position, synchronously makes print station rotate with the movement of scraper plate on one side.
When using print station with this arc-shaped peripheral surface, since the movement with scraper plate synchronously makes printing silk screen and platform part
Contact, therefore, compared with planar print station, can inhibit the printing silk when removing printing from print station with silk screen
The stretching of net has the advantages that the durability of printing precision and printing silk screen can be made to improve.
However, the printing process of the contact even with the print station with arc-shaped peripheral surface, can not also press down
Make stretching of the printing with silk screen in the in-plane direction because of caused by the frictional resistance between scraper plate.
Thus, combination silk screen plate of the invention is characterized in that this following point：Using made of metal silk screen as printing silk
Net, and the metallic plate that use intensity uses silk screen high than printing is as supporting mass, and by above-mentioned metallic plate to printing silk screen
Surrounding is kept.By the stiffening effect of supporting mass, used so as to inhibit to print because of caused by the friction between scraper plate
The stretching of silk screen in the in-plane direction is compared with the existing silk screen plate that combines, and the coordinate reproducibility of position is more preferable, and can realize height
The printing of precision.Since supporting mass is metallic plate, it can not almost deform in a thickness direction, but because of the edge of contact printing
Therefore supporting mass without deforming in a thickness direction.Although in the stripping of silk screen and platform, silk screen is drawn in a thickness direction sometimes
It stretches, but since the metallic plate by high intensity around silk screen to supporting, printing silk screen can be inhibited in thickness side
Upward stretching.As a result, a kind of combination silk screen plate can be provided, high-precision printing can be realized, and durability is good.
As printing silk screen, made of metal silk screen is used, but silk well known to capable of using such as SUS silk screens, tungsten silk screen
Net.Printing screen is not limited to the textile constructions body made of metallic fiber (sieve mesh), can also be metal mask.Especially
Ground, it is preferably a kind of to be referred to as " high sieve mesh (Japanese：Ha イ メ ッ シ ュ) ", metal wire is thin and the high-precision that is braided thinner
Silk screen.
" metallic plate " as supporting mass be not be structure latticed or fibrous as metal mask and sieve mesh,
But the component of tablet.Although it is not absolutely required to certain thickness, if certain thickness tablet, then intensity constant, is processed
It is easy and cheap.As the metal material of supporting mass, preferably Young's modulus is 70GPa or more, 640GPa hereinafter, more preferable Young
Modulus is 150GPa or more, 430GPa or less.In the case where printing to be fixed on to the lower face side of supporting mass with silk screen, in order to
Reduce the space at the difference of height between supporting mass and printing silk screen, the thickness of supporting mass be preferably 3mm or less, particularly
1mm or less.In addition, in order to inhibit to deform caused by friction of the printing between silk screen and scraper plate, thickness is preferably 0.1mm
More than.Metal printing is supported with silk screen by using the supporting mass of above-mentioned this thin-walled and high intensity, so as to
Realize that printing operation is excellent and the plates for screen printing of printing precision high (such as ± 20 μm or less).Even if in this way using high sieve mesh
The low silk screen of intensity as printing silk screen, the coordinate reproducibility of printed pattern is also high.
The coefficient of thermal expansion of supporting mass is preferably 1 × 10-6/ DEG C or more, 23 × 10-6/ DEG C hereinafter, more preferably 4 × 10-6/
DEG C or more, 11 × 10-6/ DEG C or less.Because coefficient of thermal expansion is small, the deviation of the printing precision caused by temperature change can be inhibited.By
It is metal in printing silk screen and supporting mass, therefore, is not easily susceptible to influence caused by humidity variation, is included by thickener
Expansion infiltration (Japanese caused by solvent：Swollen Run) and the caused influence of chemical change.Thus, it is made with by synthetic fibers silk screen
Printing compared with silk screen and supporting mass, excellent in te pins of durability.As this high intensity, low thermal expansion, non-hygroscopic veneer, general energy
Use such as stainless steel plate, aluminium sheet, super Invar alloy, superhard alloy, copper coin, high-strength steel sheet etc..
It is cheap since supporting mass is not silk screen but made of metal tablet.Become because being used for multiple times in supporting mass
In the case of shape, if it is necessary, also can only replace supporting mass.Further, since supporting mass is not sieve mesh structure but metal plate,
Therefore, will not a part for thickener as patent document 2 enter the seam crossing of supporting mass.
Printing silk screen keeps defined tension and is engaged with supporting mass, and supporting mass is preferably relative to printing silk screen
Tension can keep the metallic plate of the thickness of non-deformed state.Although there is the material with various Young's modulus in metallic plate, i.e.,
Keep Young's modulus big, if the plank of very thin wall, can not also inhibit to bend sometimes.Thus, it can also use and be used relative to printing
The tension of silk screen can keep the metallic plate of the thickness of non-deformed state (flat condition) as supporting mass.
Printing is preferably engaged with the print station side of supporting mass with silk screen.In silk-screen printing, the back side of silk screen plate is combined
Side is contacted with platform (or being held in the printed object of platform).In the case where printing silk screen is engaged with the upper surface side of supporting mass,
The back side of supporting mass with rigidity may interfere with platform and platform is made to damage.In addition, printing is produced sometimes with silk screen
The stretching of raw amount corresponding with the thickness of supporting mass, and generate coordinate distortion.Thus, by making printing silk screen and supporting mass
Back side, i.e. print station side engage, and so as to prevent the interference between supporting mass and platform, and can inhibit the thickness by supporting mass
The stretching of caused printing silk screen.
It is preferable that using combination silk screen plate to be applied to the contact printing of the present invention, patent document 3 is such to be used
The printing equipment of print station with arc-shaped peripheral surface.In this case, due to being contact, print can be inhibited
Displacement of the brush with silk screen in a thickness direction, and since printing silk screen is not easy in plane side because of the stiffening effect of supporting mass
It shifts up, therefore, can realize high printing precision.Further, since the movement with scraper plate synchronously makes printing silk screen and platform office
Portion contacts, and therefore, can inhibit the stretching of the printing silk screen when removing printing silk screen from print station, and make printing precision
And the durability of printing silk screen further increases.
As described above, according to the present invention, using made of metal silk screen as printing silk screen, using than printing silk screen intensity
Therefore big metallic plate, can utilize branch as supporting mass, and by above-mentioned metallic plate to being kept around printing silk screen
The stiffening effect for holding body inhibits the stretching of printing silk screen in the in-plane direction caused by the friction between scraper plate, and existing
Combination silk screen plate compare, the coordinate reproducibility of position is more preferable, can realize high-precision printing.Further, since metallic plate and silk
Net is compared, small for nonexpondable deterioration, therefore, can realize the combination silk screen plate of excellent in te pins of durability.In addition, due to by gold
In the case of belonging to the supporting mass that plate is constituted, in off-contact printing, supporting mass will not stretch, printing silk screen and printed object without
Method contacts, therefore, it is impossible to carry out thickener transfer, prints with can not be successfully, but by being combined with contact printing, can realize fine
Printing.

Fig. 1 shows the first embodiments of the contact printing combination silk screen plate of the present invention.Said combination silk screen plate 1 wraps
It includes：Frame 2；Printing silk screen 3；And supporting mass 4, the inner peripheral portion of above-mentioned supporting mass 4 are engaged with printing with the peripheral part of silk screen 3,
The peripheral part of above-mentioned supporting mass 4 is fixed on frame 2.
Frame 2 is formed as quadrangle frame-shaped by the component with thickness, and is formed to the medial movement for scraper plate in frame 2
Size.The material of frame 2 is formed by metal materials such as such as aluminum or aluminum alloy.In existing plates for screen printing, frame 2 have pair
The effect that printing is kept with the tension of silk screen 3, but in the present embodiment, supporting mass 4 to the tension of printing silk screen 3 into
Row is kept.Thus, supporting mass 4 has the function of printing silk screen 3 being fixedly supported on frame 2.
As printing silk screen 3, made of metal sieve mesh or made of metal mask are used.Made of metal sieve mesh is to thin metallic fiber
Component made of being woven can be used such as SUS sieve meshes, tungsten sieve mesh, high strength steel sieve mesh.It may be used at above-mentioned made of metal
The component of printed pattern (not shown) is dissolved in sieve mesh for example, by photoresist figure.It is especially excellent as made of metal sieve mesh
A kind of high-precision silk screen for being referred to as " high sieve mesh ", metal wire carefully and being braided thinner of choosing.Made of metal mask is to pass through example
Such as etching, laser processing, electroforming are formed with the porous metal mask of printed patterns in metal foil or metallic plate.
For supporting mass 4 by being constituted with the big made of metal veneer of 3 intensity of silk screen than printing, the peripheral part of supporting mass 4 passes through bonding
Etc. the lower surface for being fixed on frame 2.It is formed with the opening portion 4a of quadrangle, the periphery of printing silk screen 3 in the central part of supporting mass 4
Portion is fixed on the state for applying defined tension around above-mentioned opening portion 4a.Especially preferably, printing is fixed with silk screen 3
In the lower face side of supporting mass 4, i.e. platform side.The reason for this is that prevent when silk screen plate and printing are contacted with platform, it is printed on platform
Object is damaged because of the interference between support plate 4.The fixing means and supporting mass 4 and printing silk screen of supporting mass 4 and frame 2
3 fixing means can also be the joint method except bonding.
The size of supporting mass 4 preferably satisfies condition below.That is, in order to which unbiased is poorly printed, helping for scraper plate is needed
Run distance (Japanese：Help away Ju From), the width W1 on front side of the scraper plate moving direction of supporting mass 4 preferably can ensure that the overturning of thickener is steady
The size of distance before fixed.In addition, when thickener accumulation acts on Printing Department, the reason of oozing out, therefore, supporting mass can be become
Width W2 on rear side of 4 scraper plate moving direction is preferably using the size for the gutter that can ensure that thickener accumulation.In addition, scraper plate end
It needs to separate with Printing Department because effect has load, also ensures that gutter in the width direction of scraper plate, therefore, supporting mass 4 is opened
Oral area 4a, the direction orthogonal with scraper plate moving direction width D preferably uses the size shorter than the overall length of scraper plate.
Supporting mass 4 is compared with printing is with silk screen 3, by small and thickness direction the displacement of stretching when scraper in the in-plane direction
Small, high intensity metallic plate is measured to be formed.In particular, can also use the tension relative to printing silk screen 3 that can keep non-deformed
The metallic plate of the thickness of state.The material and thickness of supporting mass 4 are preferably, Young's modulus be 70GPa or more, 640GPa hereinafter,
Thickness is 0.1mm or more, 3mm hereinafter, more preferably, Young's modulus is 150GPa or more, 430GPa is hereinafter, thickness is 0.1mm
Above, 1mm or less.The coefficient of thermal expansion of supporting mass 4 is preferably 1 × 10-6/ DEG C or more, 23 × 10-6/ DEG C hereinafter, more preferably 4
×10-6/ DEG C or more, 11 × 10-6/ DEG C or less.As this high intensity, the metallic plate of low thermal expansion, can generally use for example not
Become rusty steel plate, copper coin, aluminium sheet, super Invar alloy, superhard alloy, high-strength steel sheet etc..
The function of supporting mass in existing combination silk screen plate is, bears printing by using the stretching of supporting mass itself
The deformation of plate when brush, to minimize the deformation of printing silk screen.On the other hand, the bearing in combination silk screen plate of the invention
The function of body do not lie in using the stretching of supporting mass itself bear printing when deformation, and be to around printing silk screen into
Row is reinforced, to minimize the deformation of printing silk screen.Thus, the metallic plate of high intensity is used in supporting mass 4.Although bearing
The thickness of body 4 is arbitrary, but reduces supporting mass 4 and print in the case where being slided on supporting mass 4 in the end for being designed to scraper plate
Space of the brush at the difference of height between silk screen 3, inhibits the damage of scraper plate, and therefore, the thickness of supporting mass 4 is preferably 3mm hereinafter, spy
It You Xuanwei not 1mm or less.In addition, in order to inhibit to deform caused by friction of the printing between silk screen and scraper plate, thickness is excellent
It is selected as 0.1mm or more.In addition, also can be by filling bonding agent etc. in difference of height portion, to inhibit the damage of scraper plate.
Table 1 be using SUS430 plates, Al, invar alloy material, superhard alloy as the case where the example of supporting mass 4 with make
Use existing general supporting mass i.e. polyester net as supporting mass 4 it is exemplary in the case of, the comparison sheet of each material property.
In the case of polyester net, since shape is in netted, Young's modulus is low, and coefficient of thermal expansion and humidity expansion coefficient are big, therefore,
Coordinate reproducibility is low, poor to the inhibition of deformation under load, temperature and humidity variation.In contrast, in the material of supporting mass
In the case that matter is SUS430 plates, Al, invar alloy material, superhard alloy, Young's modulus is the decades of times of polyester or more, heat
The coefficient of expansion and humidity expansion coefficient are small, and shape is plate-like, and therefore, coordinate reproducibility is high, to deformation under load, temperature change
And the inhibition of humidity variation is good.As a result, having the effect of that printing precision is got higher.
