一种适用于测试大尺寸、多层次印制电路板的新型仪器YLj—1印制电路板连线通断检测仪最近在京通过了技术鉴定。该仪器主要由一台微机、一台通断测试仪和一台打印机组成,能对24000孔单位的单层、双层和多层印制电路板进行测试,其测试面积可达381×406.4mm~2。在测板之前,能先对其矩阵线路的48000个开关功能的正确性进行自检,能灵活地检测被测板上
A New Type of Instrument Suitable for Testing Large-Size, Multi-Layer Printed Circuit Boards The YLJ-1 PCB on-line tester recently passed technical appraisals in Beijing. The instrument is mainly composed of a microcomputer, an on-off tester and a printer, which can test single layer, double layer and multi-layer printed circuit boards of 24000 hole units with the test area up to 381 × 406.4mm ~ 2. Before the test board, the matrix circuit can be the first 48000 switch function correctness of the self-test, the flexibility to test the board under test
