There are many test methods in PCBA processing plants, among which flying probe test and needle bed continuity test are more common test methods, they are all a kind of contact test, and flying probe test is an improvement of needle bed continuity test Upgraded version.

Flying probe test (FPT) is an automated test that uses a movable probe to replace the traditional fixed needle bed fixture and adds a probe drive device. In this test, two or more probes are programmed to move, and access various component pins one by one to detect whether there are open circuits, short circuits, and component value parameter errors. Since flying probe probes need to be programmed for each PCB board type, which takes a long time, PCB boards are usually suitable for prototype and small-batch PCB testing.

Flying probe test has the following advantages:

1. Since the flying probe test is supported by software, it is easier for engineers to get feedback in time in case of errors.

2. The flying probe tester is equipped with a camera to identify missing components.

3. The flying probe probe can be easily moved from one node to another, with strong precision and accuracy.

4. Flying probe test does not require fixture development, which saves test costs.

Flying probe detection is currently mainly used in industrial automation fields such as industrial detection, image recognition, instrumentation, and positioning.

Because of the close contact with shielded UUT and the ability to bring new products to market faster, and the significant advantages of not requiring more test development, flying probe test applications are bound to become more and more extensive in the future.
