Q1: What is Flying Probe Testing?

A1: Flying Probe Testing (FPT) is a automated test used evaluate proper operation of components on a PCB board. In this test two or more probes are programmed to move across the board in the air and access various component pins one by one to detect faults like Opens, Shorts, Resistance values, Capacitance values, and Component Orientation.

These probes have high precision needles which are programmed to fly over the board and test various pins on the board.

Flying Probe Testing is usually used for prototype, low volume and small batch PCB testing. However, the process has also started to be used for high volume testing. In these cases the PCB board travels to the tester though a conveyor belt where the flying probes are programmed to test various pins on the board. The flying probes need to be programmed for each PCB board type.

Features of Flying Probe Testing:

• FPT has fast checking speed and precision since it is software-based.
• The probe can be moved easily from one node to another to provides better precision and accuracy for copper pad placement and solder joints.
• Suitable for small volume production testing
• Tests each component individually and can test LEDs as well
• It doesn’t require test points as it uses vias embedded on the board as the test points.
• A flying probe tester is equipped with a camera to identify missing components and to check the component polarity.
• It is Cost-effective and can test both sides of the board
• Since FPT is software supported, it is easier for the design engineers to take feedback in the case of any error.
• Better access to nodes through vias, leads and SMT lands

This type of testing is called In-Circuit Testing. Another type of In-Circuit Testing is Grid Testing or Bed of Nails Testing.
