ABSTRACT:
In an in-circuit test fixture of the type including a bed of pins, first ends of which are adapted to contact a circuit board, means for supporting the pins, and means for making electrical connection thereto, there is disclosed an improvement wherein the pins are solid members and are freely slideable in the supporting means and wherein the test fixture includes a sheet of resilient material engaging second ends of all of the pins for providing the force necessary to urge the pins into contact with the circuit board. The means for supporting the pins includes a modular assembly which forms channels for the pins and eliminates the necessity for drilling holes in a board. The modular assembly includes a circuit board and a plurality of spring contacts for making electrical connection to the solid pins.
