Abstract
Printed circuit board testing device includes contacts arranged in a pre-determined basic grid pattern, and a pressure device for urging a printed circuit board into engagement with an adapter arrangement for electrically connecting test specimen-specific test points of the printed circuit board to be tested to grid-oriented contacts of the basic grid pattern of the printed circuit board testing device. The adapter arrangement includes a flexible adapter foil that carries on the side facing the basic grid pattern preferably regularly-arranged lands and on the side facing the test specimen test specimen-specific lands that are in direct contact with the test points of the printed circuit board to be tested. The mutually-assigned lands are electrically interconnected on both sides of the adapter foil by plated-through holes and, if necessary, associated printed conductors. In order to provide compensation for manufacturing deviations of the very small test points from a reference position, provision is made for the adapter foil and the printed circuit board to be retained in the adapter arrangement and displaced relative to each other in their plane. The adapter foil can also be elastically elongated or stretched in its plane.
