What follows is that the detection and maintenance of PCB boards are becoming more and more difficult. In order to test whether the components on the circuit board meet the specifications and solderability, for example, if you want to check whether there is any problem with the resistance on a circuit board, the easiest way is to measure the two ends of the metal contacts with a multimeter. However, in a mass-produced factory, it is very inefficient to use a meter to slowly measure the correctness of each resistor, capacitor, inductor, and even the circuit of an IC on each board. Moreover, more and more complex PCB circuit boards, faster bus speeds, etc., are very great challenges for detecting PCB boards. For functional testing in this environment, simply using a multimeter is obviously unable to obtain results quickly and accurately. In high-density and highly integrated printed circuit boards, there are very large requirements for electrical testing and functional testing of circuit boards. The high-density probe contacts make it very difficult to detect PCB boards with a multimeter, and the detection efficiency is low. Moreover, the content of the testing work is huge, which puts a greater test on the ability of production line testing workers.
