The second method is to let the designer of the circuit board factory beside a piece of copper foil around the circuit board pad, the attachment area is large, the pad is not easy to fall off, if there is no space around the pad beside the copper foil, th
In the rapid development of science and technology today, a variety of high-tech electronic products emerge in an endless stream, which makes the demand for printed circuit boards increase sharply, manufacturing difficulties are becoming higher and higher
In addition, before the solder resistance film coating, the printed circuit board surface is treated by plasma, and a certain roughness and high activity surface can be obtained, so as to improve the adhesion of the solder resistance film.
Circuit board manufacturing, circuit board design and PCBA processing manufacturers explain the original PCB high-frequency circuit board manufacturing process
Description method is to manufacture the circuit board requires the least tools, manufacturing process is the simplest of a method, but the accuracy is not very high, suitable for beginners.
Circuit boards, also known as printed circuit boards or PCBS, can be found in every electronic device in the world today. In fact, the circuit board is considered the foundation of the electronic device because it is the place where the various components
