ABSTRACT:
A test fixture for testing printed circuit boards on a test computer includes a base, a probe plate on the base and a top plate in spaced relation above the probe plate. The probe plate has a predetermined array of spring loaded primary contact probes mounted therein, and the top plate has a plurality of secondary contact probes mounted therein in alignment with and in the same predetermined array as the primary contact probes in the probe plate. The top plate is adapted for receiving and positioning a printed circuit board thereon so that predetermined areas of the printed circuit board are aligned with the secondary contact probes, and the fixture is actuatable for drawing the top plate toward the probe plate to cause the primary contacts to engage the secondary contacts and to thereby move the secondary contacts into engagement with the predetermined areas of the printed circuit board.
