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.
Our technology allows us to produce Flying Probes with a 0.2 mm plunger, making it possible to work on very narrow pitches.
There is the possibility that the Flying Probe contact two adjacent points at the same time, but the challenge that Giacomo, the owner, accepted in 1986 is precisely to prevent that from happening, fully respecting tolerances and play.
Depending on the size, the applicable current rating of our Flying Probes ranges from 3A to 5A.
The smaller the diameter of the head, the lower the rated current supported.
The typical contact resistance of Flying Probe is 30 mΏ.
For the construction of the Flying Probe we use:
Working in most cases with very small diameters, the types of heads used are those that best suit these conditions.
The most used are:
