Protel 2004中元件封装库的创建方法

Creating methods of component packaging library in Protel 2004

Protel 2004软件为电子设计者提供了极为丰富的元器件库,众多的库文件安装调用时比较麻烦,对每个设计者来说,应用的只是庞大元件库中的一部分,而且在实际使用中还会经常碰到库中的元件不能满足需要,为了使PCB制作过程中库的调用不再繁琐,方便实用,这就需要设计者自己动手制作元件库,以使电路设计过程变得轻松容易。

Protel 2004 provides fairly abundant component libraries for the circuit designers,but it is difficult to install and use so many library files. Normally each designer just uses part of these component libraries and he often finds that the com-ponents in the libraries can’t meet his needs. Therefore,it is necessary for the users to create their own component libraries in order to use the libraries easily during PCBs making and make the circuit design simple.
