用Protel99SE快速设计印刷电路板的方法

The Method of Rapid Design PCB with Prote199SE

印刷电路板（Printed Circuit Board）简称PCB，它是电子产品中电路元器件的支撑件，提供电路元件和器件之间的电气联接。在电子制作中，正确、快速地设计印刷电路板，能使电子设备的结构更为合理、紧凑，并且使设计效率及整机电性能指标大大提高，电子设计人员的劳动强度大大降低。因此掌握印刷电路板的快速设计方法十分必要。

Printed circuit board, PCB for short, is a strut member of circuit components in the electronic product, which supplies the electric linking between electronic components and devices. During the electronic manufacture, design a printed circuit board rapidly and correctly can make the structure of the electronic equipment more reasonable and compact, can also improve the efficiency of design and the whole electromechanical performance target, reduce the labor intensity of the designers. So grasp the rapid design method of PCB is quite necessary.
