Firstly, during the production and processing of PCB boards, there will be a certain proportion of defective products. At this point, we need to use mechanical equipment to inspect and screen out unqualified defective products. Therefore, we need to conduct electrical testing. So, what is the difference between testing and flying needle testing?

　　The testing is divided into test fixture testing and flying needle testing,

　　In terms of speed, the test frame test will be faster, and the flying needle test will be slower

　　In terms of cost, the cost of testing racks is higher

　　As for which testing method to choose, we need to choose based on the number of PCBs. For those with a large number, choose a testing rack, and for those with a small number, choose flying pins

　　Based on cost, time efficiency, and comprehensive evaluation and selection
