Origin Of Printed Circuit Boards

The creator of printed circuit boards is Austrian Paul Eisler. In 1936, he first used printed circuit boards in radios. In 1943, Americans mostly used this technology in military radios. In 1948, the United States officially recognized this invention for commercial use. Since the mid-1950s, printed circuit boards have been widely used. Printed circuit boards appear in almost every electronic device. If there are electronic parts in a certain device, they are also mounted on PCBs of various sizes. The main function of PCB is to connect various electronic components to form a predetermined circuit, play the role of relay transmission, and is a key electronic interconnection component of electronic products, known as the "mother of electronic products."
