板级测试指南 [英]
Printed-circuit boards used to be works of art, and the PCB designer was an artist as well as a technician. Components had many different shapes, sizes, and colors, and the traces connecting them were graceful arcs in beautiful patterns.
在过去，一块印刷电路板就是一份艺术品，印刷电路板的设计人员不仅仅是一名技术人员还是一位艺术家。器件有不同的形状、大小和颜色，而且连接器件的导线形式优美。
Today’s boards, by contrast, are boring. On a typical modern digital PCB assembly, for example, the parts are all squat rectangular components, and the traces are laid out with a precision only a computer could love.
相比之下，现在的电路板令人厌烦。例如，在一块标准的数字印刷电路板上，所有的器件都是有棱有角的，布线的精度也只有计算机才可以完成。
Test methods for PCB assemblies have changed as well. In the past, nearly all testing was functional testing, and it was performed with bench top instruments or a custom tester. Today, the test engineer has many more options, including in-circuit testers, manufacturing defects analyzers, and several types of functional testers.
对印刷电路板装配的测试方法也已经改变了。以前，几乎所有的测试都是功能性测试，使用传统的测试仪器或台式设备就可以完成。今天，测试工程师有很多选择，包括在线测试设备，制造缺陷分析设备和一些功能测试设备。
