FOG function testing for capacitive touch screens. Today, we will share with you a small production clip. As we all know, electronic products cannot be separated from electronic testing. Basically, every process needs to be tested once to ensure that the function is useful, so as not to produce defective products and cause greater losses in the future. Some of them are already irreparable, so don‘t seem simple. Every job position should be rigorous.
So after we bind the FPC to the capacitive touch screen, we glue it to fix the position between the FPC and the functional chip, and then perform functional testing. The first step is to test whether the FPC we bind is OK. Everyone should know about the functional chipThe circuit on the board is very small, and careless or incorrect FPC binding position can cause circuit breakers in the product.
So you should also see the display on the computer in the picture, most of which are green, and there is also one that says PASS and the value is 99.98%, so FPC binding is not a problem. Basically, our FPC binding yield is still very high. This capacitive touch screen is a USB interface capacitive screen.
