Gramophones had printed circuit boards

PCB's were around in the early-to-mid 1900's and were used insome gramophones and tube radios. They might not have looked like the PCB's wesee today, but no matter, they helped introduce new advancements intoconsumers, just as they do today.

The first PCB's were funded by a music printing company

Paul Eisler, who is sometimes referred to as the Father ofthe Modern Printed Circuit Board, was an Austrian inventor who was working at amusic printing company in the mid-1900’s. He shared his idea for a new invention— what would become the very first printed circuit board and the companydecided to bankroll his idea. His invention led directly to the types ofprinted circuit boards we produce today.

Why Do they Tend to be Green?

The green material you see on the PCB layout is the soldermask. But these days, solder mask can be made in many different colors — so whyhave printed circuit boards continued to stay green? Some think it can betraced back to their use in the American military, where both rigid and flexiblecircuit boards have been common since development of the auto-assembly processin the mid-1950's.

PCB’s were vital to space travel

As an integral part of NASA’s space program, printed circuitboards helped get the Apollo 11 astronauts safely to the moon and back. Circuitboards are lightweight and require only a small amount of electricity, so theywere ideal for complex electronics in close quarters, such as a spacecraft.

So, don’t assume these types of technologies are a newtechnology. They have had a long, and significant history.
