PWB for IC Testers <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

  • Wires and connects conventional manual wiring on boards by using pre-insulated copper wire.
  • Electric characteristics are stable.
  • Capable of reducing development periods and costs.
  • Compared with a multilayer board, theoretical values and measured values can match easily, so it is easy to implement required characteristics.
  • As wiring design and its alteration are easy, the probe card is suitable in high-density wiring.
