An in - circuit tester tests a digital ic using the ic ' s truth table 在线测试设备采用真值表来测试数字集成电路。
The first test an in - circuit tester performs is a shorts - and - opens test 在线测试完成的第一项测试任务就是短路、开路测试。
After performing the shorts and opens test , the in - circuit tester tests each component on a pcb assembly one at a time 在线测试完成的第一项测试任务就是短路、开路测试。
After performing the shorts and opens test , the in - circuit tester tests each component on a pcb assembly one at a time 短路、开路测试完成以后,在线测试仪需要在同一时间对印刷电路板上的每一个器件进行测试。
These testers cost less than in - circuit testers , and some manufacturers claim that tests run faster on mdas 这些测试设备所需要的费用要比在线测试设备少,而且有些制造商还宣称在生产缺陷分析设备上,测试速度进行的更快。
