Printed Circuit Board Fabrication Ordinary Board Conformal Coating FR4
Printed Circuit Board Fabrication Description:
1. Provide mechanical support for fixing and assembling various electronic components such as integrated circuits, realize wiring, and electrical connection or electrical insulation between various electronic components such as integrated circuits, and provide required electrical characteristics.
2. Provide solder mask graphics for automatic welding, and provide identification characters and graphics for component insertion, inspection, and maintenance.
3. After the electronic equipment adopts printed boards, due to the consistency of similar printed boards, manual wiring errors are avoided, and automatic insertion or mounting of electronic components, automatic soldering, and automatic detection can be realized, which ensures electronic products. quality, improve labor productivity, reduce costs, and facilitate maintenance.

Printed Circuit Board Fabrication Introduction:
The creator of PCB is the Austrian Paul Eisler, who first used printed circuit boards in radios in 1936. In 1943, Americans mostly used this technology in military radios, and in 1948, the United States officially recognized this invention for commercial use. Printed circuit boards have only been widely used since the mid-1950s. Printed circuit boards are found in almost every electronic device. If there are electronic parts in a device, they are all mounted on PCBs of various sizes. The main function of the PCB is to make various electronic components form the connection of the predetermined circuit, which plays the role of relay transmission. It is the key electronic interconnection of electronic products and is known as the "mother of electronic products".
