When Was The Printed Circuit Board Invented

By | March 8, 2023



The printed circuit board (PCB) is a cornerstone of modern electronics and has revolutionized the way our lives are run. But the question remains: when was it first invented?

The history of the printed circuit board dates back to the early 1900s, when the inventor Austrian Paul Eisler developed the radio for the British government. To make it smaller and more efficient, he used a flat metal plated with a thin layer of conducting material – effectively the world’s first PCB.

Eisler’s invention didn’t gain much traction at the time, however – the printed circuit board was largely ignored until the early 1940s. It was then that American engineer and scientist, Charles Durcase and other inventors took what Eisler had done and began to develop their own versions. The US Navy, who were looking to standardize the design of electronic equipment and save valuable space on ships, quickly embraced the technology and pushed its development.

By the 1950s, PCBs had become so popular that they were being used in a variety of consumer devices, such as radios and televisions. In the same decade, Americans Alfred Yee and Eugene Yust invented the printed circuit board assembly process, further increasing the popularity and efficiency of the PCB.

By the 1960s and 70s, advancements in the technology meant printed circuit boards were now being used for more complex tasks, such as controlling essential functions in computers and other sophisticated machines. With the invention of the microprocessor in the late '70s, the printed circuit board became an essential part of every computer system.

Today, printed circuit boards are used for all kinds of applications, from small consumer products to large-scale industrial and military machines. And thanks to the advancements made by Eisler, Durcase and others, the printed circuit board is one of the most important components in modern technology.
