Flying probe testers for PCBs are instruments designed to test PCBs with high-density component layouts, many layers, high wiring density, and small test point distances. They mainly test the insulation and conduction values ​​of circuit boards. Testers generally use the "true value comparison positioning method" to monitor the test process and fault points in real time to ensure test accuracy. Flying probe testers for PCBAs mainly perform electrical tests on the values ​​and electrical characteristics of electronic components.
