PWB for IC Testers <Probe Card>

Image of <Probe Card>

The probe card makes it possible to use Multi-wire technology, improve the timing accuracy and low-crosstalk design by high precision, equal length wiring of characterictic impedance.

Features

  • Rainforce the power and grand by reducing signal layer with high density MWB.
  • Lead time of 1st article could be 12 days with MWB including design by MWB including pattern designing.
  • Board size for Probe Card Wcould be produced the maximum size of ø560mm diameter.

Application

  • Probe card for IC tester
