Description
Technical field
The present invention particularly relates to a kind of in laser wire mark silver paste line turn about a kind of touch panel laser circuit etching structure
The line-spacing that bevel edge is increased in the confined space at angle, improve in conventional process because caused by when cabling line-spacing is too small routing line width it is different
The touch panel laser circuit etching structure of cause.
Background technique
Currently, the electronic products such as common various mobile phones, media player, navigation system, digital still camera start on the market
Mating various types of touch screens can be divided into resistance-type, condenser type, infrared-type and surface acoustic wave type, capacitor according to its principle
It is most commonly seen that formula touches screen (hereinafter referred to as capacitance plate).The functional layer of capacitance plate is mainly by the electrically conducting transparent positioned at visible area
Electrode and the cabling in edge non-visible area domain are constituted, open circuit between each electrode, and each cabling is then connect with electrode, is formed several
Channel.Large-sized capacitance plate in especially, there are many port number, and the design of product then needs narrower frame, because
This requires the line width and line-spacing of edge cabling higher and higher.
In currently available technology, the edge cabling of capacitance plate generally by silver paste wire mark or metal-plated film layer Lithography Etching and
, wherein cost is relatively low for silver paste wire mark method, but line width/line-spacing is generally good in 120/120 micron~80/80 micron range
Rate is higher, and line width/line-spacing is smaller, and yield is lower.And metal-plated film layer Lithography Etching method, then can make the line width of edge cabling/
Line-spacing reach 30/30 micron and hereinafter, but its need by metal coating, photoresist coating, exposure development, baking, acid system erosion
Numerous cumbersome process such as quarter, demoulding, and equipment investment is big, cost is very high, therefore at present mostly in silver paste wire mark mode as mainstream.
Please refer to shown in Fig. 1, Fig. 2 to Fig. 4, the design of the configuration of silver paste wire mark be first silver paste is coated on complete it is transparent
A silver slurry layer 3 is formed on the touch base plate 1 of 2 processing procedure of electrode, then laser etching line 31 is etched with laser processing procedure and separates cabling 33
Complete configuration.In general, the etched path of laser is all vertical, horizontal, the corner line-spacings wire lengths (Pa=such as or not integrally
Pb=Pc, Lm > ... > L2 > L1) design, as shown in Figure 2.The laser movement routine 32 of laser etching machine is galvanometer control, in odd number
Can be different from scanning direction when even number route, it is as shown by arrows in Figure 3, in general, practical under ideal zero deflection situation
Etching the cabling 33 come each other can be equidistant.
It is that single galvanometer is mobile when vertical, horizontal linear direction although laser etching machine scans back and forth direction difference, Yu Yi
As in the case of line-spacing between laser etching line 31 can still keep equidistant or deviation is little.However, working as 31 line-spacing of laser etching line
When minimum (less than 80 microns) and laser scanning speed are very fast, two galvanometers are mobile simultaneously when corner, are easy to happen thunder at this time
The deviation of movement routine 32 is penetrated, line-spacing (Pa, Pb, Pc) unequal situation is caused, as shown in figure 4, will cause 33 line width of cabling not
Unanimously, the problem of causing cabling 33 meticulous or breaking, just have to reduces scanning speed at this time reduces production capacity, therefore still needs to be changed
It is good.
