Abstract
The invention relates to a method for manufacturing a glass double-layer functional sheet at a low cost. The glass double-layer functional sheet is composed of glass, a top transparent electrode layer, a bottom transparent electrode layer and a flexible circuit board. The manufacturing method includes the following steps that (1), patterns which are composed of multiple unit electrodes are manufactured on the front face and the back face of the glass, wherein a protrusive head is arranged at the front end of each unit electrode, and therefore the top transparent electrode layer and the bottom transparent electrode layer of a visible region are formed; (2), the protrusive heads of all the unit electrodes are covered with the flexible circuit board, and then hot-pressing binding is performed to form the complete functional sheet. The method has the advantages that the technology is simple, the number of production steps is decreased, the cost is low, and the yield is increased.
Description
Technical field
The present invention relates to a kind of method making capacitance touch screen glass double pattern functional sheet, particularly the method for a kind of low-cost production capacitance touch screen glass double pattern functional sheet.
Background technology
At present, the double-deck functional sheet of traditional glass due to cabling quantity more, tens can be reached, and cabling generally needs silk-screen silver slurry, live width is 0.1mm, calculate by monolateral 15 lines in left and right, at least need the width of 3mm, binding position has 30 at least with upward wiring, required width is larger, present mobile phone is more and more higher with the dull and stereotyped requirement to screen accounting, requires that frame is more and more narrow, uses this technology mode cannot reach the ultra-narrow limit requirement in market; Silver slurry is collected to hot pressing bindings bit, width and the spacing of hot pressing position only have 0.2mm respectively, the bad of off normal can be increased, silver slurry line have height and large less than glass hard (HRC65Yi Shang), when binding with flexible PCB hot pressing, centre is used for the uncertainty of metal geode explosion of turning circuit, also can affect yield and production cost is high.
Summary of the invention
In view of prior art Problems existing, the invention provides that a kind of technique is simple, the method for the double-deck functional sheet of the making capacitance touch screen glass glass of low cost, concrete technical scheme is, the method of a kind of low-cost production capacitance touch screen glass double pattern functional sheet, capacitance touch screen glass double pattern functional sheet comprises indium oxide tin glass, top layer electrode layer, bottom electrode layer, flexible PCB, it is characterized in that: electrode layer is bound the pattern held and be made up of several cell electrode of an outstanding head by each cell electrode hot pressing, method for making comprises the following steps
, indium oxide tin glass front is not needed etching paste on pattern position silk-screen, silk-screen goes out pattern, silk-screen etching paste thickness is 14um ~ 16um, printing line thickness is 0.2 ~ 0.3mm, conveying type oven is sent to toast, temperature is 130 DEG C ~ 140 DEG C, transfer rate is 1.5 ~ 1.8m/min, the product be baked is put into cleaning machine and washes etching paste, namely remaining pattern is the top layer electrode layer pattern wanting to obtain;
, bottom electrode layer pattern is in the same technique of indium oxide tin glass reverse side
make;
, indium oxide tin glass top layer electrode layer outstanding first end hot pressing flexible PCB, hot pressing temperature 170 ~ 180 DEG C, time 12 ~ 15s;
, at the outstanding first end hot pressing flexible PCB of indium oxide tin glass bottom electrode layer, hot pressing temperature 170 ~ 180 DEG C, time 12 ~ 15s;
