Flying Probe Insights

What is Flying Probe?

Flying probe testing (also known as a 'flying probe') is an automated test methodology for inspecting printed circuit board assemblies (PCBAs). It uses movable probes to make electrical contact with test points on the PCBA, checking for shorts, opens, resistance, capacitance, and other parameters without requiring a custom test fixture. It is commonly used for low-volume production, prototyping, and board repair.

What other technologies are related to Flying Probe?

Flying Probe Competitor Technologies

In-circuit Test

In-circuit test (ICT) is a powerful alternative to flying probe testing. Both verify circuit operation and component placement, but ICT uses a bed-of-nails fixture for faster testing of high-volume production, while Flying Probe is often preferred for low to medium volume or prototype boards due to lower fixture costs.

ICT

ICT, or In-Circuit Test, is a direct competitor to flying probe testing. Both verify circuit operation, but ICT utilizes a bed of nails fixture to make contact with numerous test points. This allows for faster testing in high volume, but is much less practical for low volume or prototyping.

Flying Probe Complementary Technologies

Boundary Scan

Boundary scan (JTAG) is complementary to flying probe because it tests digital interconnects and device functionality by serially shifting data through boundary scan cells, which a flying probe cannot directly access. Boundary scan is often used in conjunction with flying probe to achieve more complete test coverage.

AOI

Automated Optical Inspection (AOI) uses cameras to visually inspect circuit boards for defects like solder joint problems or missing components. It is complementary to flying probe testing, which tests electrical performance. AOI can catch visual defects that a flying probe might miss, while the flying probe tests electrical functionality. The combination of AOI and Flying Probe can offer comprehensive testing.
