FULL RASTER CARTRIDGE FOR A PARALLEL TESTER FOR TESTING AN UNPOPULATED PRINTED CIRCUIT BOARD, SPRING CONTACT PIN FOR SUCH A FULL RASTER CARTRIDGE AND ADAPTER FOR TESTING AN UNPOPULATED PRINTED CIRCUIT BOARD

摘要

invention, componentization is not without a printed circuit board for inspection to a parallel tester for full grid cassette (full grid cassette), relates to such a full grid cassette contact pin spring (spring contact pin), and the adapter for the parallel tester for testing a printed circuit board that is not componentized (adapter). According to a first aspect of the present invention, the spring contact pins are fixed to the grid in the pool by the film cassette. According to another aspect of the present invention, a full grid cassette, can be moved relative to each other in the axial direction of the spring contact pin and includes two plates having a clearance perpendicular to the axial direction. According to a third aspect of the present invention, the spring contact pin is designed as a central contact point of the spring. According to another aspect of the invention, the adapter the scanning head (scanning head) provided with a contact pin is provided, the contact pin has a fixing projection (locking projection) for fixing them relative to fall onto the guide plate of the adapter there.
