2N3A8204-B 印刷电路板组装

PCB是印刷电路板(即Printed Circuit Board)的简称。又称印制电路板、印刷线路板，由于它是采用电子印刷术制作的，故被称为“印刷”电路板。印刷电路板是组装电子零件用的基板，是在通用基材上按预定设计形成点间连接及印制元件的印制板。该产品的主要功能是使各种电子零组件形成预定电路的连接，起中继传输的作用，是电子产品的关键电子互连件,有“电子产品之母”之称。PCB作为电子零件装载的基板和关键互连件，任何电子设备或产品均需配备。

PCB is the abbreviation for Printed Circuit Board. Also known as printed circuit board or printed circuit board, it is called a "printed" circuit board because it is made using electronic printing technology. A printed circuit board is a substrate used for assembling electronic components. It is a printed board that forms point to point connections and printed components according to predetermined designs on a universal substrate. The main function of this product is to connect various electronic components into predetermined circuits, playing a relay transmission role. It is a key electronic interconnection component of electronic products and is known as the "mother of electronic products". PCB, as the substrate and key interconnecting components for electronic parts loading, is required for any electronic device or product.
