The Flying Probe test consists in examining every point of the board with a dedicated probe, allowing in this way to test any type of PCB, even in small scale operating exclusively on a software of the testing machine.
The In Circuit Test uses the so-called “bed of needles” mounted on a fixture. The production of the fixture and the related software for programming the test machine are expensive. They also are difficult to update if there are changes to be made to the board to be tested. If you have to test standard devices, or in large scale, the “bed of needles” is certainly the quickest and most convenient choice, when testing small series or prototypes you need to use an ICT system with the Flying Probes.
Moreover, thanks to the Flying Probe technology it is possible to reach precision in terms of dimensions up to 0.2 mm, and we at Tecon are able to build specific Probes for any machine.
