ABSTRACT:
A printed circuit board "bed-of-nails" test fixture, of the type in which the circuit board is moved into electrical contact with the test probes, is provided with a means of ensuring accurate registration between the test probes and the corresponding test nodes on the board when contact is made. This registration is achieved by allowing the support surrounding the circuit board to bend by a hinge mechanism on all four sides, as the circuit board travels towards the probes. The substantially equal opposed forces on opposite edges of the board prevent lateral movement of the board during travel and thus ensure accurate registration.
