在深入了解电磁效应的基础上去设计印制电路板,比在试验室里光搭样板再逐步测试的传统办法通常会获得更好的设计效果。许多印制电路板的设计师在设计工作中至今仍十分依赖在试验室里先搭样板再逐步调试的传统办法。但是,从今天的情况看,产品的复合程度越来越高,相应的特点是信号也越来越快,其结果是会派生出新型的定时误差,而要在一块试验样板 Designing a printed circuit board based on an in-depth understanding of the electromagnetic effects is usually better than the traditional approach of taking a step-by-step test in the lab. Many designers of printed circuit boards still rely heavily on traditional approaches to design and prototype in the lab. However, judging from today’s situation, the degree of compounding of products is getting higher and higher, and the corresponding characteristic is that signals are getting faster and faster. As a result, a new type of timing error is derived and a trial model
