ABSTRACT:
An interface device for converting the test point grids of machines for electrically testing unassembled printed circuit boards to a lower density grid, to be interposed between the test machine grid (1) and the corresponding fixture (3). The interface device comprises a plurality of flat parallel plates (10, 11, 12, 13, 14) suitably perforated so that needles can pass through them, the plate (14) facing the grid (1) having the same perforation as the grid (1) and having some of its holes (21) unoccupied by said needles (15), whilst the outer plates (10, 11) have all the holes occupied by said needles (15), reproducing the desired lower density grid configuration.
