SMT与印刷电路板的设计

SMT and the Design of Printed-Circuit-Board

从ＳＭＴ的工艺要求出发，讨论了使用ＳＭＤ时设计印刷电路板的总体要求，提出了在利用ＰＲＯＴＥＬ设计软件时各种元器件的制作要求、制作方法以及布局规范。

According to the SMT The paper discusses the general principle for designing the PCB board using SMD.The principle and methods for making different devices have been gotten in this paper,the layout's rules of device are also given.
