The modern PCB has its roots in early 20th century science and engineering. In 1903, German inventor Albert Hanson first described flat foil conductors laminated to an insulating board in multiple layers. However, it was not until after World War II that the United States Army, which had worked with the technology to make proximity fuses on a large scale, made printed circuit boards available for commercial use. During the war, the anti-aircraft proximity fuse needed an electronic circuit that could be produced in quantity. To do so, engineers used a ceramic plate that was screen printed with metallic paint for conductors and carbon for resistors. Ceramic disc capacitors and subminiature vacuum tubes were soldered in place. In the early stages of PCB manufacturing, assembly was done via through-hole construction, meaning that each componentâ€™s leads were passed through drilled holes in the PCB before being soldered to the PCB trace. Advances in technology over the years have allowed for more efficient assembly techniques and, as a result, higher quality boards.
