8920-PS-DC-02 印刷线路板 提高电子设备的质量和可靠性

8920-PS-DC-02 印刷线路板，又称印制电路板（PCB，Printed Circuit Board），是重要的电子部件，是电子元器件的支撑体，也是电子元器件电气连接的载体。由于它是采用电子印刷术制作的，故被称为“印刷”电路板。印刷线路板主要由绝缘底板、连接导线和装配焊接电子元件的焊盘组成，具有导电线路和绝缘底板的双重作用。它可以代替复杂的布线，实现电路中各元件之间的电气连接，不仅简化了电子产品的装配、焊接工作，减少传统方式下的接线工作量，大大减轻工人的劳动强度；而且缩小了整机体积，降低产品成本，提高电子设备的质量和可靠性。8920-PS-DC-02 印刷线路板按层数来分的话，可以简单到只有一层或两层铜，也可以有多达五十层或更多层的复杂设计。它们所用的基材通常由纸基或玻璃布基制成，表层一面或两面粘上覆铜箔再层压固化而成。此外，印刷线路板也可以根据用途和制作方式的不同，分为刚性板、挠性板、刚挠结合板、金属基板和陶瓷基板等多种类型。

8920-PS-DC-02 Printed Circuit Board, also known as Printed Circuit Board (PCB), is an important electronic component that supports electronic components and serves as a carrier for electrical connections. Due to its use of electronic printing technology, it is called a “printed” circuit board. Printed circuit boards are mainly composed of insulating substrates, connecting wires, and solder pads for assembling and soldering electronic components, which have a dual function of conductive circuits and insulating substrates. It can replace complex wiring and achieve electrical connections between components in circuits, simplifying the assembly and welding of electronic products, reducing the workload of traditional wiring methods, and greatly reducing the labor intensity of workers; Moreover, it reduces the overall volume, lowers product costs, and improves the quality and reliability of electronic equipment. If the 8920-PS-DC-02 printed circuit board is divided by layer, it can be as simple as only one or two layers of copper, or as complex as fifty or more layers in design. The substrate they use is usually made of paper or glass cloth, with one or both surfaces glued with copper foil and then laminated and cured. In addition, printed circuit boards can also be classified into various types based on their usage and production methods, including rigid boards, flexible boards, rigid flexible bonding boards, metal substrates, and ceramic substrates.
