What is Flying Probe Test?
The Flying Probe Test is an electrical test method where movable test probes contact individual points on the PCB without a fixed fixture.
The Flying Probe Test uses motorized probes (typically 4-8) that move freely across the board, sequentially contacting test points. It checks shorts, opens, component values and polarity.
Process and Application
The key advantage is flexibility: no fixture means no lead time and no tooling costs. Ideal for prototypes, NPI and small to medium series. The trade-off is longer test time per board compared to ICT.
