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.
随着芯片集成度和印刷电路板复杂度的不断提高,边界扫描测试技术在芯片故障检测中的应用越来越广泛。
With the continual improvement of the chip's integration level and complexity of print circuit board, the application of boundary scan test technology becomes wider and wider in testing ICs.
短路可能导致印刷电路板不能通过其它测试,在对电路板上电后,会损坏测试设备或电路板。
Shorts may cause a PCB to fail other tests and may damage the tester or the board under test if you must apply power to the board.
这个测试程序适用任何类型象针脚,插座,继电器,电线,连接器,印刷电路板等电流通道载体或其结合体。
This test procedure may apply to any type or combination of current carrying members such as pin and socket contacts, relay contacts, wire and crimp connectors, or printed circuit board and contact.
简单介绍了在线测试这一概念;阐述了印刷电路板在线测试的流程和原理;分析了几种在线测试中的工艺性测试。
The article introduced the concept of on-line test, expounded the flow and theory of on-line test for PCB(printed circuit board), and analyzed several technics of on-line test.
本文硬件设计主要包含了电路原理图设计、系统印刷电路板设计和系统测试。
In the part of hardware design of this paper, circuit schematic design, PCB design and system testing have been included.
为了跟上变化的印刷电路板技术,近些年来,在线测试设备已经增加很多功能。
To keep up with changing PCB technology, manufacturers of in-circuit testers have added features in recent years.
对印刷电路板装配的测试方法也已经改变了。
印刷电路板(简称pcb)测试机的测试算法是PC B测试机的核心,它直接决定测试机的测试功能和测试速度。
The core of PCB (printed circuit board) tester is testing algorithm, which directly determines the testing functions and speed of PCB tester.
很多测试设备具有分界扫描的功能,这样,测试人员就可以直接测试印刷电路板上的互连,而没用必要使用探针去测试每一个节点了。
Many in-circuit testers now have boundary-scan test capability. With boundary-scan testing, you can test interconnections on PCBs without using a probe on each node.
我一旦测试,PC板,我将提供它出售,无论是作为只是一个印刷电路板或作为一个完整的测试单位。
Once I have tested the PC board I will be offering it for sale either as just a PCB or as a complete tested unit.
我一旦测试,PC板,我将提供它出售,无论是作为只是一个印刷电路板或作为一个完整的测试单位。
