20090251161 | Module for Test Device for Testing Circuit Boards - A module for a tester for the testing of circuit boards is described. Such testers have a basic grid on which an adapter and/or a translator may be arranged in order to connect contact points of the basic grid with circuit board test points of a circuit board to be tested. The module comprises a support plate and a contact board. The contact board is formed by a rigid circuit board section which is described as the basic grid element, and at least one flexible circuit board section. Provided on the basic grid element are contact points which each form part of the contact points of the basic grid. The basic grid element is mounted at an end face of the support plate, and the flexible circuit board section is bent in such a way that at least part of the other section of the contact board is parallel to the support plate. Each of the contact points of the basic grid element is in electrical contact with conductor paths running in the contact board and extending from the basic grid element into the flexible circuit board section. | 10-08-2009 |
20080272793 | Finger Tester for Testing Unpopulated Printed Circuit Boards and Method for Testing Unpopulated Printed Circuit Boards Using a Finger Tester - The present invention relates to a finger tester for the testing of non-componented printed circuit boards using at least two test fingers ( | 11-06-2008 |
20080272792 | Method and Device for Testing of Non-Componented Circuit Boards - The method according to the invention is used to determine deviations of circuit board test points of a series of circuit boards from the CAD data relating to these circuit boards, by scanning the surface of the circuit board by an imaging method and subjecting this image to automatic image analysis so that it may be compared with the CAD data. The CAD data are then suitably corrected so that, with the aid of the corrected CAD data, the circuit board may be tested in a finger tester, with test fingers of the finger tester being controlled on the basis of the deviations found. | 11-06-2008 |
