Tokusen Probe Pin Needle / Spring Probe

Tokusen is a specialist in specialty metal wire production from ultra fine wire to steel cord for automotive tires.

Tokusen's spricalty metal wires have been used widely from Semi-conductor, electronics, medical to automotive industries. Probe Needle / Probe Pin for testing wafers in the semiconductor industry and Spring Probe for testing wafers / semi-conductoer package / circuit board are major application.

High Precision Probe Needle / Probe Pin

Tokusen supplies probe card pins with ultra high accuracy and consistent quality. Thanks to its integrated production process (drawing, straightening, heat treatment, machining and bending), Tokusen can satisfy any of your requirement.
