It has many advantages, such as that simple and convenient, reaction speed is fast, saves space, is easy to exchange and be widely used in various electronic products.
Current touch screen most common on the market is capacitive touch screen, capacitive touch screen with the advantages such as long lifespan, light transmittance height at
For most widely used touch screen.
Capacitive touch screen is a kind of mobile intelligent terminal（Mobile phone, tablet computer etc.）Important accessory, capacitance touch
The production procedure of screen is：Plate ito film in big glass baseplate, and be coated, expose, developing, etching etc. processes it is final in big
Glass baseplate stamps ITO pattern, forms touch screen circuit, then cuts touch screen circuit, connects IC, pressing FPC, patch
It closes the processes such as face glass and forms complete touch screen products, and screen products will be touched and tested, dispatched from the factory.Because its circuit is extremely smart
Carefully, in process of production because there are the bad phenomenons such as line short, open circuit for the various factors such as technique, raw material, artificial.It passes at present
The mode of the detection circuit of system is that worker's hand is detected by magnifying glass on light table, or finished product access circuit test plate is simulated
Test.Some Enterprises can buy complicated, expensive detection device, but expensive equipment improves production cost, is unfavorable for promoting
With use.
Finished product access circuit board testing can only be corresponded to finished product to be detected, but touch screen itself is by multi-layer film structure
It made of fitting, is detected again to the finished product stage, bad if there is circuit, then full sheet is scrapped, rather than single layer is scrapped.Institute
To use artificial detection under normal circumstances, it is ensured that detect that the circuit of single layer is bad before lamination coating.Due to artificial detection
Means include the detection of light table and blue light light irradiation, the copper lines on touch screen can be placed directly on light table, then with putting
Big mirror is observed, and line width line-spacing about 15-40um, general hand magnifying glass can be observed.For not seen on touch screen
（Light transmittance is higher）ITO circuits then need use blue light light irradiation, this clarity compared with metallic circuit is poor, and enlargement ratio is not
Erroneous judgement is easy in the case of foot.Cause operating personnel because long-time hand magnifier observation eyes are easy fatigue, causes under efficiency
Drop.It is low that accordingly, there exist manual detection efficiencies, and human cost is high, False Rate also can because proficiency there are it is unstable the defects of.
