Test Probes as PCB Components

Compared to conventional multi connectors test probes can be used more flexible as contacting elements. Test probes have a great positioning tolerance and are able to compensate installation tolerances between the components to be connected (please refer to fig. 1). A special advantage is the assembly in the field. A difficult arranging of multi connectors is not necessary. This allows an assembly under various angles without having a close look on the connection – blind mating. Also a high amount of contacting cycles is no problem for the test probes. The continuous force of the spring ensures a vibration-proof connection.
The standard gold plating and the used material provide a long lifetime and a small electrical resistance. For direct equipping on the PCB, test probes with SMT or THT are available.
With Interface Pin Blocks ‘FKB’ several test probes can be equipped at once in a defined pitch. If the test probes are not meant to be assembled directly on a PCB, test probes with solder cups or crimp connectors can be used.
The perfect test probe depends on the application. Because of that, PTR offers customized solutions in addition to a wide range of standard test probes. Often only a slight variation of standard products is enough. We are using our knowledge in terminal blocks and multi connectors technology to create the ideal contact for your application. Also packaging solutions like tape on reel are available.
