Flying Probe PCB Testing provides high fault coverage with accuracy and repeatability. There's no requirement for a test fixture.

By using electro-mechanical controlled probes to access components on a PCB assembly, the flying probe delivers accurate tests in the shortest times.

Probe precession can access various assembled  components such as PLCCs, SOICs,PGAs, SSOPs, QFPs and others on PCB assemblies.                          

Advantages of Flying/Roving Probe Testing:

Good for prototypes/low volumes

Access less demanding

Relatively low non-recurring-engineering-costs
