PCB(Printed circuit board)是一个最普遍的叫法,也可以叫做“printed wiring boards” 或者 “printed wiring cards”。在PCB出现之前,电路是通过点到点的接线组成的。这种方法的可靠性很低,因为随着电路的老化,线路的破裂会导致线路节点的断路或者短路。
PCB (printed circuit board) is the most common name, which can also be called "printed wiring boards" or "printed wiring cards". Before the emergence of PCB, the circuit was composed of point-to-point wiring. The reliability of this method is very low, because with the aging of the circuit, the rupture of the line will lead to the open circuit or short circuit of the line node.
绕线技术是电路技术的一个重大进步,这种方法通过将小口径线材绕在连接点的柱子上,提升了线路的耐久性以及可更换性。
Winding technology is a significant progress in circuit technology. This method improves the durability and replaceability of the line by winding small-diameter wire around the column of the connection point.

当电子行业从真空管、继电器发展到硅半导体以及集成电路的时候,电子元器件的尺寸和价格也在下降。电子产品越来越频繁的出现在了消费定送水 保定骨伤骨病 铜鼎铜钟 淤泥固化设备 保定舞蹈 化粪池钢模具 保定网站建设领域,促使厂商去寻找更小以及性价比更高的方案。于是,PCB诞生了。
When the electronic industry develops from vacuum tubes and relays to silicon semiconductors and integrated circuits, the size and price of electronic components are also declining. Electronic products appear more and more frequently in the consumer field, prompting manufacturers to find smaller and more cost-effective solutions. So PCB was born.
