1MRK000173-CCr00 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.

1MRK000173-CCr00 In electronic equipment, PCB as the support and connection of electronic components of the infrastructure, 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.

1MRK000173-CCr00 Manufacturing process, although a variety of methods, but 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.
