Pogo Pin / Probe Pin Evaluation

Pogo Pins (*1) and Probe Pinsare parts widely used when temporary electrical connections are required.
OKI Engineering performs evaluations of probe pins used for wafer testing, all the way up to probe pins used for high voltages, such as IGBT, etc., in the environment of their actual use.

  • *1:  A Pogo pin is an elastic probe loaded with a spring by which the tip of the probe expands and contracts. Pogo pin is a registered trademark of Everett Charles Technologies (California, USA).
