这篇论文给出了研究控制的阻抗电路板测试过程的结果。它旨在对将要做这类板子的厂家提供可控阻抗电路板生产的一般介绍,并对那些可能想改进他们当前工艺的厂家提供建设性意见,因此,除了考虑测试问题外,在准备生产高质量可控阻抗电路板时,还要求注意某些其他主要科目领域即设计、材料和制造的标准。这篇论文的内容是建立在由MEPD Met-Etch(Selkirk)有限公司于他们的苏格兰制造工厂中实施的生产实验基础上,是联合王国政府防御研究合同的一部份。这项研究结果包括在联合王国防御机构(电子局)的报告中,并且其后也被详述在专用的“设计者指南”文献中。这个文献后来被单独地提交到希望并入 CECC 2300核准系统(Approval System)的 ECL 19中。为了验证试验结果,还通过其他电路板工厂利用适当的测试设备量程进行了比较测量。在印制电路板工业中,对可控阻抗板测试的简单方法有不断增加的要求。这篇论文提倡使用计算机控制测试方法,这样在生产环境下,生产人员能够做精确和重复的测量。如果实现这种方法,那么使用通常统计过程控制技术,在可控阻抗板生产上,封闭质量循环是可能的。
This paper presents the results of a controlled impedance circuit board testing process. It is intended to provide a general introduction to the production of controlled impedance circuit boards for the manufacturers who will do such boards and to provide constructive advice to those manufacturers who may want to improve their current processes. Therefore, in addition to considering the testing issues, Quality controllable impedance circuit board, but also pay attention to some other major areas of discipline that is the design, materials and manufacturing standards. This essay is based on production experiments conducted by MEPD Met-Etch (Selkirk) Ltd. in their Scottish manufacturing facility as part of a government defense research contract with the United Kingdom. The results of this study are included in the report of the United Kingdom Defense Agency (ETA), and are subsequently detailed in the dedicated Designer’s Guide. This document was later submitted separately to ECL 19 which is expected to be incorporated into the CECC 2300 Approval System. In order to validate the test results, comparative measurements were also made by other circuit boards using the appropriate test equipment range. In the printed circuit board industry there is an increasing demand for simple ways to test controlled impedance plates. This paper advocates the use of computer-controlled test methods so that production personnel can make accurate and repeatable measurements in a production environment. If this approach is implemented, it is possible to close the mass-circulation in the production of controlled impedance plates using the usual statistical process control techniques.
