Abstract
The present invention is a structure of printed circuit board (PCB) tester and mainly comprises a first density fiberboard, a circuit transformation board, and a second density fiberboard. Corresponding to the positions of a plurality of conductive components having a comparatively wider center spacing on an universal density fiberboard of a base, a plurality of conductive components are evenly distributed on the first density board and, corresponding to the positions of the probes on a probe card located above the second density fiberboard, a plurality of conductive components having comparatively narrower center spacing are evenly distributed on the second density fiberboard. The circuit transformation board is placed between the first and the second density fiberboards with close contact points densely distributed on one side of the circuit conversion board to match perfectly with the conductive components on the second density fiberboard and loose contact points loosely distributed on the other side of the circuit transformation board to match perfectly with the conductive components on the first density fiberboard while a conductive copper foil circuitry is applied to connect each pair of corresponding contact points. By using the circuit transformation board, the originally close center spacing of the PCB under test can be properly widened up to effectively lower the test cost and save the tool changing cost and time.
