ABSTRACT:
An in-circuit test fixture for use in making a non-functional electrical inspection of individual components and/or circuit paths on a printed circuit board or wired backpanel assembly. The present in-circuit test fixture is cost effective and can be used when only small or moderate numbers of printed circuit boards have to be tested. The present test fixture eliminates the necessity for drilling holes in a support plate. Rather, a test head unit and a transition head unit are put together in modular fashion using assemblies which may be positioned in stacked arrays to provide a two-dimensional series of channels for support of pins to provide a test head for testing a two-dimensional product and to provide a two-dimensional series of channels for support of pins to provide a transition head for interconnection with an electronic circuit analyzer.
