Power supply assembly for a semiconductor circuit tester

摘要

A power supply assembly includes a dielectric substrate and a power supply circuit supported by the dielectric substrate. A conductive connection block is attached to the dielectric substrate at a main surface thereof and is connected to a power supply terminal of the power supply circuit. A spring probe pin is fitted in a bore formed in the connection block and includes a conductive sleeve and a conductive plunger fitted in the sleeve. The conductive sleeve is in electrically conductive contact with the connection block.
