ABSTRACT:
A test interface between a two sided circuit board to be tested and a test controller and it generally includes an upper and a lower test fixture each including personality plates having bores for simultaneously guiding translation pins into contact with test nodes on the circuit board under test. Circuit board tooling bores are mounted on tooling pins in the personality plates. The tooling pins tapered to a diameter slightly larger than the diameter of the circuit board tooling bores. One or both personality plates are mounted such that they may move responsive to forces exerted on the tooling pins because of nonalignment such that the forces tend to equalize. This results in better overall alignment.
