  • Test fixture for printed circuit boards having a dual seal system
    Patent number: 5430385
    Abstract: A test fixture for printed circuit boards having an initial seal member and a final seal member. The test fixture includes a probe plate with a pair of channels about its periphery for receiving a pair of seal members. An initial seal member is positioned in the outer channel in the probe plate to spring-bias the diaphragm board and provide an initial seal for the test fixture. A final seal member resides in the inner channel in the probe plate and provides an absolute seal for the test fixture. The final seal does not move during operation thereby reducing friction wear. The two seal members operate separately from one another and can be replaced individually without replacing the other.
