Head shape (tip) and pitch (grid) of spring contact probes
Choosing the right Contact Probe head makes the difference between achieving a normal contact or an excellent electrical contact. We are capable of saying so because since 1986 our customers have taught us that research and individualization on each order is very important to get the best results. We are therefore sure that examining and solving any problem concerning the electrical contact in the ICT (In-Circuit Test) with the customer, is the best strategy to deal with any request.
You will find below the various heads of Contact Probe in the catalog:
The following are some examples of our solutions to deal with the choice of head according to the situation:
In order to choose the right head of a Spring Probe, the pitch that determines the distance between one Probe and another in the formation of the final grid should be noted.
The most common pitches are those at 2.54mm and 1.27mm. In order to perform a good job, it is also necessary to remember to evaluate the diameter of the head in relation to the distance of the holes on the fixture.
We at Tecon are able to produce Spring Probes with a head diameter up to 0,2 mm.
