The creator of the printed circuit board was the Austrian Paul Esle Paul Eisler, who first adopted a printed circuit board on the radio in 1936. In 1943, Americans used the technology for military radios, and in 1948 the United States formally recognized the invention for commercial use.
Since the mid 1950s, the printed circuit board has become widely used. Before the PCB appears, the interconnection between the electronic components is based on the direct connection of the wire. Today, wires are used only in laboratories for experimental applications, and printed circuit boards have definitely dominated the electronics industry.
