Summary of the invention
The utility model provides a kind of proving installation of electronic product machine core board, adopts printed circuit board, test probe, organic glass support to form each test point that can make things convenient for, accurately test the electronic product machine core board.
The utility model provides a kind of proving installation of electronic product machine core board, the organic glass testing jig that comprises band folding cover plate, described testing jig is provided with the printed circuit board that connects each test point, it is pcb board, corresponding described test point is laid test probe above it, and described printed circuit board side is provided with the terminal that the test point signal is outputed to testing tool.Described terminal is connected with copper sheet with test probe, connects more reliably like this, and probe is fixed to scolding tin and does not need 502 glue on the printed circuit board.
Further, each test point has corresponding plate hole on the described printed circuit board, is welded with telescopic test probe on described plate hole.
Further, described proving installation also has the input and output terminal of sound signal, electric current, voltage, the test of low-and high-frequency signal wave.The socket that also has the port of the various accurate signals that are used to peg graft on the printed circuit board of described proving installation.
Further, the organic glass testing jig and the printed circuit panel edges of this band folding cover plate are fixed by screw, and the printed circuit board of different test functions is installed in adjustment according to the test needs.
The proving installation of a kind of electronic product machine core board that the utility model provides, the printed circuit board that employing designs replaces organic glass to make the substrate of test probe, need not weld electric wire like this, time saving and energy saving, and the entanglement problem can not connect up, test probe is accurately located, and stablizes each test point of contact measured product machine core board.Described a plurality of test probe is communicated with the welding of described printed circuit board, reaches stable testing, reliable, long service life, lowly safeguards, making is easy, with low cost.
Signal output terminal connects with copper sheet with probe, does not need manual line, and probe does not need glue to fix yet, because probe is a copper product, is welded direct on the circuit plate hole more reliable and more stable.The measurement circuit plate of band probe is directly directly revised in electronic core plate original to be tested with wiring board software and is formed, and by the circuit board plant manufacturing, test point 100% is aimed at, and stops the big problem of the artificial bore error of traditional organic glass.
Further, the folding cover plate skeleton of this proving installation is fixed with screw with the measurement circuit panel edges, can install according to the adjustment of test needs, tests other different machine core board if desired, only need the corresponding test printed circuit board of testing jig transposing is tested, convenient and swift.Exempt and repeat to make folding lid skeleton.
