Abstract
The invention discloses a kind of manufacture crafts for improving touch screen yield, are related to touch screen technology field, including etching, printing, tab blanking, combination, pressing, functional test, final inspection, finished product shipment inspection, packaging and other steps.The present invention is not to be placed directly in be solidified on net vehicle, the increase cured process of one of UV instead of after printing silver paste；Silver paste is put into net vehicle again and waits for oven for solidifying, it is just had cured since silver paste prints and then surface, the knitting wool and dust to descend slowly and lightly again below, so that it may wind, it is dustless rolling or washing by way of clean up laser again, so as to improve in laser process because these knitting wool, foreign materials away yield.
Description
Technical field
The present invention relates to touch screen technology fields, and in particular to a kind of manufacture craft for improving touch screen yield.
Background technique
In prior art technology for manufacturing touch screen, print steps include that the printing of Ag route and solidification two parts are completed, warp
Cross since silver paste solidification is in oven after Ag route print steps, solidification differs for 20~60 minutes, so general production be for
Effective use oven room and time, can all print tens (determining according to size), be placed on net vehicle, then to push baking solid
Change, just will do it curing schedule for a long time so can be spaced, intermediate link has residual knitting wool and dust descends slowly and lightly in silver paste table
Face, and it is included wherein by silver paste, to can not be cleaned up by modes such as wind, dustless rolling, washings after solidification；Significantly
Reduce the yield of printing.
Application No. is 201710881195.9 Chinese patent applications to disclose a kind of manufacture craft of capacitive touch screen,
Including cutting ito glass, manual sliver, ultrasonic cleaning, visual examination, pad pasting, wiping binding area, front surface A CF are pasted by hand,
Positive pre- patch FPC, reverse side ACF are pasted, and reverse side pastes FPC, voltage tester in advance, and positive OCA is pasted, and film, reverse side are taken off in CG fitting manually
OCA is pasted, and reverse side is bonded LCM, deaeration, detection；Ito glass uses borosilicate type glass；The silicon dioxide layer thickness of ito glass exists
20nm~30nm.Making step simply, conveniently, a kind of natural man-machine interaction mode.But due to simple technique, make his life
Produce qualification rate decline.
Summary of the invention
The shortcomings that in order to overcome existing above-mentioned technology, the invention discloses it is a kind of improve touch screen yield manufacture craft,
It can make the output increased of touch screen.
To achieve the above object, the present invention provides technical solution below: including etching, printing, tab blanking, combination,
Nine pressing, functional test, final inspection, finished product shipment inspection and packaging steps.
The print steps include the printing of Ag route, UV solidification, solidification.
The UV curing time is 12-15 seconds.
The acid of the etching is hydrochloric acid and nitric acid is the mixed acid of 12:1 by weight.
The lead material of the pressing be one of PET, FPC or more than one.
Drying temperature is 65 ± 5 DEG C in the etching step.
The beneficial effects of the present invention are:
The present invention is not to be placed directly in be solidified on net vehicle, the increase cured work of one of UV instead of after printing silver paste
Sequence；It is i.e. every to have printed a silver paste, directly product is put on UV curing apparatus, UV only needs silver paste surface can be consolidated for more than ten seconds
Change, then silver paste be put into net vehicle and waits for oven for solidifying, behind to send to the subsequent handlings such as oven for solidifying again identical；Since silver paste prints
And then surface just has cured, behind the knitting wool and dust that descend slowly and lightly again, so that it may cleaned by way of wind, dustless rolling or washing
Clean laser again.So as to improve in laser process because these knitting wool, foreign materials away yield.
Detailed description of the invention:
