Advantages of Flying Probe Tests
Perhaps more importantly, a flying probe is very accurate. It can measure values at 99% accuracy, ensuring you’ll have no issues with your end product. Another benefit is that you don’t need to make design decisions with the testing in mind.
Detect electrical and circuit problems,such as apertures, short circuits, capacitance and resistance (polarity, absences, faulty soldering, wrong or defective components, tolerances…).
The main advantage of flying probe testing is the substantial cost of a bed-of-nails fixture.
Easy modification of the test fixture when the PCBA design changes.
