测试产品的仪器能够几乎立刻发现印刷电路板的缺陷,如果同样的任务由人来完成,那将花费很长的时间,而且不如机器准确。
A machine can examine a circuit board for faults almost instantly. A human would take far longer to do the same thing, and would be less accurate.
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。
After performing the shorts and opens test the in-circuit tester tests each component on a PCB assembly one at a time.
通过可测性设计,使该电路的测试难度及测试时间减少了将近一半。
By design for testability, both the degree of difficulty in testing and test time are reduced nearly one half.
