The History of the Printed Circuit Board

The young engineer Paul Eisler didn’t like the tangle of wires that connected the tubes, coils and resistors in the radios of the 1930s, aptly named bird’s nests.

The ingenious idea of the inventor, who had emigrated from Vienna to London, was to print a clear system of conductive paths on a single plane suitable for mass production. It was not until 1948 that the public learned of the printed circuit, which went on to triumph worldwide and is one of the most important inventions of the 20th century.

Paul Eisler had to wait a long time for recognition. It was not until 1971 that he was awarded the invention of the printed circuit. If we were Google, we would create a Doodle for Paul Eisler with the Google lettering as a strip line.
