The Differences Between PCB Test Fixtures and Flying Probe Testing
In the process of and PCB manufacturing, ensuring their electrical performance and quality is crucial. PCB test fixtures and flying probe testing are two common methods for electrical performance inspection. So, what are the differences between them? PCB Test Fixture A PCB test fixture is a specialized device used to test the electrical performance of PCBs. By simulating the actual working environment of the PCB, it ensures that each board functions properly before being put into use. The test fixture uses probes to make contact with test points on the PCB, transmitting signals to a control unit. The control unit executes pre-set test programs to detect issues such as short circuits, open circuits, etc., and records the test results. PCB test fixtures are suitable for large-scale production. They use a test bed with multiple pins to directly contact multiple points on the PCB. This method is hig...
