【PCB信息网】讯 PCB 英文全称为 Printed Circuit Board，中文名称为印制电路板，又称为印制线路板、印刷电路板、印刷线路板。 PCB 的雏型来源于 20 世纪初利用“线路”（Circuit）概念的电话交换机系统，它是用金属箔切割成线路导体，将之黏着于两张石蜡纸中间制成。

Test Coupon，是用来以 TDR (Time Domain Reflectometer 时域反射计) 来测量所生产的 PCB 的特性阻抗是否满足设计的要求，一般要控制的阻抗有单端线和差分对两种情况，所以 test coupon 上的走线线宽和线距(有差分对时)要与所要控制的线一样，最重要的是测量时接地点的位置。
