Background technique

PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. The creator of the printed circuit board was the Austrian Paul Eisler, who first used it in a radio in 1936. In 1943, Americans mostly applied this technology to military radios. In 1948, the United States officially recognized this invention for commercial use. Printed circuit boards have only been widely used since the mid-1950s. Before the appearance of PCB, the interconnection between electronic components was done by direct connection of wires. Today, wires exist only for experimental applications in the laboratory; printed circuit boards have definitely occupied a position of absolute control in the electronics industry.
