Description
Technical field
The present invention relates to the technical fields of the printed elements such as solar battery sheet, high-accuracy electronic component, more particularly to
A kind of production method of metal alloy composite halftone.
Background technique
With the increasingly increasing of energy demand, energy problem has become restriction the great of international community's economic development and asks
Topic, this promotes people constantly to explore new energy, and wherein the research of solar energy occupies critical role.Solar battery is as too
One of the core technology that sun can be studied, has also obtained quick development, the transformation efficiency for improving solar battery is mesh in recent years
The main study subject of preceding solar battery, in addition to cell substrate material selection and optimization, the improvement of cell piece manufacture craft etc. are wanted
It asks outer, the printing process of suitable high-precision and high-stability is taken to can also be improved the transformation efficiency of solar battery.In the sun
In the printing process of energy battery, the use of printing screen plate has a significant impact to final printing quality.
The conventional solar cell piece printing production method of composite halftone, is typically coated with one on the silk screen to have stretched tight
The emulsion of the photosensitive class of layer, uniform adhesion recycles the shading of film pattern, is exposed on exposure machine on silk screen after drying
The part of light, pattern light leakage solidifies under the action of photosensitizer, and the part of shading does not solidify, and when development, which will rinse out, not to be solidified
Emulsion, the figure just needed on the halftone space of a whole page, to complete the transfer of figure.The halftone of which production has one
Fixed limitation: one, emulsion bad assurance of resolution under the action of light, the flatness of line edge after exposure development
It is bad, it is easy when use to influence the printing quality of lines；Two, the adhesion strength of emulsion and steel wire grenadine is bad, after exposure development very
It is easy to cause space of a whole page emulsion to fall off, to largely effect on plate-making yield；Three, emulsion wearability is bad, is rubbed when printing with substrate
Wiping is prone to wear spillage, influences surface printing quality and service life；Four, lines are influenced by light ray energy stability when exposing
It is larger, it is easy to cause line weight uneven, when batch making influences production yield, and when use influences printing stability；Five, by
The influence of emulsion strike through, printing lines can not narrow down to narrower range, be unable to satisfy the requirement of high-precision hachure printing.
In conjunction with above-mentioned limitation, we constantly make the halftone of printing in the new process of exploration.

10%；
2) this product in non-pattern and needs to have sheet metal and film layer dual support in Printing Zone, far more than silk screen and film layer
The bond strength service life can promote 30% or more；
2) outline that laser goes out is clearly smooth, and line width is uniform, very poor to can control within 1um, prints out
Lines plastotype is more preferable, has a clear superiority compared with conventional plates；
2) under the action of high molecular bonding glue, keep polymer compound layer adhesion strength extremely strong, it is not easily to fall off, it greatly improved
Plate-making yield, probably in 50%-60%, which plate-making yield can reach 80%-90%, greatly improved conventional plates yield
Stock utilization saves production cost；
3) polymer compound layer superpower wear-resistant, so that film layer broken hole not easy to wear, printing service life mention halftone when in use
It doubles above, the screen painting service life of the conventional plates average level 50,000 or so, and the screen painting longevity made from which
Life can averagely reach 100,000 or more, even higher, and print later period printing lines and will not widen, and have obviously to cell piece efficiency
Advantage；
4) the halftone lines strike through of which production is more preferable, therefore can substantially compress the limitation of high-precision narrow linewidth,
On the basis of ink of the same race printing, design line thickness can recompress 2-5um, and print well, and line style is good, in this way to battery
Piece efficiency has the promotion become apparent.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
