Brief history of PCB
The inventor of the printed circuit board was Austrian Paul Eisler, who used a printed circuit board in a radio device in 1936. In 1943, the Americans used the technology extensively in military radios. In 1948, the United States formally recognized the invention for commercial purposes. Since the mid-1950s, printed circuit technology began to be widely used. Before the appearance of printed circuit boards, the interconnection between electronic components is to rely on direct connection of wire. Later, the circuit panel only exists as an effective experimental tool. And now, printed circuit board has occupied the absolute dominance of the position in the electronics industry.
