Adapter for electronic testing equipment for circuit boards and similar

Abstract From the Canadian patent

Adapter arrangement for electronic test equipment for wiring carriers such as circuit boards and similar, with an adapter board (8) in the form of a plated through hole circuit board to equalise locally raised connection densities between the regular basic grid (3) of the testing device and the variably arranged connection points (6) of the test specimen (4), with springy means of contact to equalise possible vertical variations in contact height on the test specimen. The new and inventive feature consists of the fact that on each contact area (12, 13) on at least one side of the adapter board (8) is at least one cushion-like plug (14, 15) made from an electrically conductive springy …
