We design jigs and substrates for relay boards and provide proposals for specific requirements in a timely manner.

Substrates are designed by utilizing our experience and knowledge for impedance control, isometric wiring, and base material selection, etc.

We can design WLCSP peripheral at 150 μm pitch. Available pitches vary according to sequences and specifications. Please contact us.

We design substrates that can tolerate  high current and high voltage, which are increasingly required.

We design and produce probe cards and relay boards for testing wafers.
