[0002] Touchscreens work by utilizing the induced current from the human body, which can quickly and accurately identify the touch position, making touch operation smoother and more natural. Function chips are an important component of touchscreens. When a function chip is damaged, the touchscreen cannot function. Therefore, the testing of function chips is crucial.
[0003] The existing functional chip testing mainly involves manual testing using a multimeter to touch the gold fingers of the functional chip. Since there are multiple gold fingers on the functional chip and many contacts on the gold fingers, multiple tests are required during testing, which is prone to errors, resulting in low testing efficiency and accuracy.
