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.

Power supply assembly for a semiconductor circuit tester

A test head for a semiconductor integrated circuit tester, the test head includes a power supply board mounted to a power distribution board and positioned between the power distribution board and a device interface board. The power supply board includes a power supply circuit having power supply input terminals for receiving electrical power at a voltage Vand force and return terminals for supplying regulated electrical power at a voltage V. The power supply board further includes a power connector for connecting the force and return terminals of the power supply circuit to power supply contact elements of the device interface board.
