模块和接口卡概述：

模块和接口卡是针对中高档的模块化路由器、交换机产品而言的，对于固定配置的路由器和交换机而言不涉及模块和接口卡。通常网络模块是为了扩展局域网功能而开发，而接口卡则多指广域网接口卡，通过广域网接口卡，路由器和交换机产品就可以方便的实现更高效能的广域网接入。

PCB（ Printed Circuit Board），中文名称为印制电路板，又称印刷线路板，是重要的电子部件，是电子元器件的支撑体，是电子元器件电气相互连接的载体。由于它是采用电子印刷术制作的，故被称为“印刷”电路板。

对PCB的各种性能(电气、物理、化学、机械等)的要求，可以通过设计标准化、规范化等来实现。这样设计时间短、效率高。

Module and interface card overview:

Modules and interface cards are for mid-to-high-end modular routers and switches, and do not involve modules and interface cards for fixed-configuration routers and switches. Usually, the network module is developed to expand the functions of the local area network (LAN), and the interface card refers to the wide area network (WAN) interface card, through the WAN interface card, routers and switches can conveniently achieve more efficient WAN access.

PCB (Printed Circuit Board), the Chinese name is called printed circuit board, also known as printed circuit board, is an important electronic part, is the support body of electronic components, is the carrier of electrical interconnection of electronic components. Because it is produced by electronic printing, it is called a "printed" circuit board.

The requirements for various properties (electrical, physical, chemical, mechanical, etc.) of PCB can be achieved through design standardization, standardization, etc. This design time is short, high efficiency.
