Abstract
The utility model relates to a simple keyboard thin-film circuit board function test jig, which is provided with a big printed circuit board (PCB), a small printed circuit board, a flexible flat cable and flexible flat cable adapters; a USB (universal serial bus) connecting cable and thirty sets of changeover toggle switches; each set of changeover toggle switch corresponds to a line of a thin-film circuit board, and the changeover toggle switches are connected in parallel to form parallel branches; connectors are soldered on the small printed circuit board; both ends of the flexible flat cable are respectively connected to the big printed circuit board and the small printed circuit board through the flexible flat cable adapters; and the USB connecting cable, the parallel branches and the connectors are formed into a serial circuit. The simple keyboard thin-film circuit board function test jig adopts the USB connecting cable to supply power, the changeover toggle switches are arranged according to a circuit diagram corresponding to the thin-film circuit board, and whether light-emitting diodes can normally emit light is observed by pressing the thin-film switch keys of a keyboard in order to judge whether the electrical properties of the thin-film circuit board are good; the fabrication cost of the jig can be reduced, the testing time is saved, and the accuracy is increased.
