  • Patent number: 5663655
    Abstract: A test fixture provides ESD protection to electronic switching circuitry in a universal grid type fixture having test probes arranged for electrical contact with a printed circuit board under test and in which test signals are sent between the circuit board and a high speed electronic test analyzer through intervening switching circuits. The test fixture includes a movable probe plate, a test probe mounted in the probe plate, the test probe including a movable plunger for making electrical contact with a printed circuit board during a test cycle, the plunger being movable between a first position and a second position, and a ground plane on the movable probe plate connected to electrical ground, the probe plunger having a ground plane contact element that contacts the ground plane in said first position of the plunger and which moves out of the contact with the ground plane when the plunger moves to the second position.

  • Patent number: 5493230
    Abstract: A translator pin retention system for a translator fixture for a printed circuit board tester having a pattern of test probes facing away from a base plate upon which the translator fixture is mounted. The fixture comprises a plurality of essentially parallel and spaced apart translator plates having patterns of preformed holes for containing and supporting straight, solid translator pins extending through the plates of the translator fixture for use in translating test signals between test points on a printed circuit board supported by the fixture and the test probes on the base of the tester. A thin, flexible pin retention sheet of an elastomeric material rests on one of the translator plates so that the translator pins that extend through the translator plate on which the sheet rests also extend through the pin retention sheet.
