1MRK002238-DAr00 印刷电路板

1MRK002238-DAr00 Printed circuit board (PCB) is an electronic component that uses organic materials or inorganic substrates to route, bury or mount components to achieve electrical connectivity and functional realization. It is formed by covering a surface conductor layer and a perforated conductor layer, and welding capacitors, resistors and other components to a manufactured copper-covered exposed drill hole. PCB has the characteristics of heat resistance, corrosion resistance, wear resistance, etc., and is an essential part of electronic products.

In electronic devices, PCB as the support and connection infrastructure of electronic components, connecting and supporting chips, sensors, power supplies and other components, to achieve a variety of functions. Different industries and applications of PCB has different characteristics and requirements, for example, in the communications industry, PCB needs to have high frequency characteristics, anti-interference ability and stability; In the automotive electronics industry, PCB needs characteristics such as high temperature resistance, anti-shutdown and anti-interference.

1MRK002238-DAr00 In the manufacturing process, although there are various methods, they generally include photographic plate making, image transfer, etching, drilling, hole metallization, surface metal coating and organic material coating steps. These steps ensure the PCB’s accuracy and functionality.

In general, printed circuit boards are an integral part of modern electronic equipment manufacturing, and their performance and quality have an important impact on the stability and reliability of the entire electronic equipment.
