PCB（Printed Circuit Board），中文名称为印制线路板，简称印制板，是电子工业的重要部件之一。几乎每种电子设备，小到电子手表、计算器，大到计算机，通讯电子设备，军用武器系统，只要有集成电路等电子元器件，为了它们之间的电气互连，都要使用印制板。在较大型的电子产品研究过程中，最基本的成功因素是该产品的印制板的设计、文件编制和制造。印制板的设计和制造质量直接影响到整个产品的质量和成本，甚至导致商业竞争的成败。
Printed circuit board (PCB), whose Chinese name is printed circuit board, is one of the important components in the electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers, communication electronic equipment and military weapon systems, as long as there are electronic components such as integrated circuits, printed boards should be used for the electrical interconnection between them. In the process of large-scale electronic product research, the most basic success factors are the design, documentation and manufacturing of the printed board of the product. The design and manufacturing quality of printed board directly affect the quality and cost of the whole product, and even lead to the success or failure of commercial competition.
Function of PCB
After the electronic equipment adopts printed boards, due to the consistency of similar printed boards, the error of manual wiring is avoided, and the automatic insertion or installation, automatic soldering and automatic detection of electronic components can be realized, which ensures the quality of electronic equipment, improves labor productivity, reduces cost and is convenient for maintenance.
