PCB Test Fixture

Particle Interconnect MCM-L membrane test fixture

PI used on flex-circuit material to form a translator bare-board test fixture. The translator is constructed by using a simple two-sided, plated-through-hole, printed circuit board (PCB), which is coated with PI on both-sides. The translator PCB accommodates the difference between off-grid test points of the unit under test (UUT) and the universal grid of the board test system. The bottom side matches up with the testers on-grid pads. Traces from the bottom side connect to the top side with plated-through holes. The translator PCB becomes the test fixture.

0.010" pad, 0.015" pitch, 0.004" compliance.
