Testing device for electronic testing of a sample and method for producing a device

摘要

The semiconductor wafer testing system a terminal system (7) with electrical contacts (12) on the underside of a circuit board (10) with conductor wires. The contacts may be hemispherical with the contact surface (12c) at the bottom accurately machined flat. The contact layer (22) is deposited on a base contact layer (12a) connected to the conductors in the circuit board.
