Abstract
A device for testing printed circuit boards and/or flat modules for electrical circuits is indicated, wherein at least one support plate (3) equipped with contact pins (4, 4') of different lengths is located in a housing (1). A cover plate (7) is positioned above the support plate (3) and contains at least one receptacle (10) for a test sample in the form of a printed circuit board or flat module. In addition, a unit (16) is provided for producing a partial vacuum to pull the test sample against the contact pins (4, 4'). To perform the in-circuit and the function tests, the underside of the cover plate (7) containing the receptacle (10) for the test sample has a slide (12) with spacers (15) protruding at right angles from one of its sides, which is able to move between two end positions, crosswise to the movement of the test sample. The slide (12) restricts the path of the test sample moving from its resting position by means of the partial vacuum, to two different planes in accordance with the different lengths of contact pins (4, 4').
