Printed circuit board (Printed circuit board, referred to as PCB) is a substrate for assembling electronic parts, and is a printed board that forms point-to-point connections and printed components on a general substrate according to a predetermined design. The main function of PCB is to make a variety of electronic devices form a predetermined circuit connection, play the role of relay transmission, is the key electronic interconnection of electronic products.
The manufacturing quality of printed circuit boards not only directly affects the reliability of electronic products, but also affects the overall competitiveness of system products, so PCB is known as the “mother of electronic products”.
At present, a variety of electronic products such as personal computers, mobile phones, digital cameras, electronic instruments, vehicle satellite navigation devices, car drive parts and other circuits, all use PCB products, which can be seen everywhere in our daily life.
With the design trend of diversified functions, miniaturization and lightweight weight of electronic products, more small devices are added to the PCB, more layers are used, and the use density of the device also increases, making the application of PCB complicated.
PCB empty Board through SMT (surface mount technology) parts, or through DIP (double in-line package) plug-in plug-in the entire process, referred to as PCBA (Printed Circuit Board Assembly).
