What is Flying Probe testing and how is it performed?
• As the fixture costs are very high, a fixture less type of testing is used. The test machine has probes, normally 4 to 16 probes on both sides that move to each location of the net and checks for opens and shorts. This type of testing is more economical for small prototype runs. For quantities of more than 10 boards with more than 2500 nets, fixture testing (bed of nails) is faster. We extract the netlist from your Gerber Data or using your IPC-356D format to test 100% Short and Open.
