The resistive touch screen deviates from the backlight problem

scanning: time:2020-05-22

Q: I have a supplier whose resistive screen and screen have been shifted, and the whole size is larger than my chassis, so it cannot be loaded. Can you help me to analyze the reason?A lot of their incoming material is like that now, right?This gives us a headache in quality.

A: the best medicine to solve headache is to gradually analyze and eliminate:

 1. Please confirm the production cycle and use cycle, it is recommended to use up the installed machine within three months (the FPC of the screen and the resistance screen will be subject to bending stress, and the stress will continue to push the double-sided adhesive tape, the longer the time is, the greater the probability of moving); 

2. Environmental storage, it is recommended to store at room temperature of 25 ° c;

3. In r & d design, an iron frame can be added to raise the height of the iron frame above the backlight to prevent the touch screen from moving;

4. Use 3M high adhesion and high temperature resistant adhesive paper and increase the viscosity width of double-sided adhesive.
