It has been well established that prototype printed circuit boards are a very complex puzzle in themselves. Their usage is of a variety and they come in different sizes that depend on the use of it. And one thing is fixed for it, that it’ll always be an amalgamation of different components to come together for its assembly.
Putting all these parts together can be a bit time taking and complex but we can break it down into the most common components to further understand its uses.
If you’re familiar with the purpose of prototype printed circuit boards or PCB fabrication, you probably know how commonplace and necessary they are in today’s technologically dependent world. But even though printed circuit boards are found in almost every device we use on a daily basis, you might not know these four amazing facts about PCBs:
1.Some gramophones had printed circuit boards.
If you come to think of it, prototypes PCBs aren’t something that is entirely a new concept. They were there is early 1900sand after that too. And they were used in a few gramophones and also tube radios. They might not look similar to the printed circuit board prototypes that we are used to seeing now, but no matter what the format was, they helped in bringing entertainment and new developments into our homes like they do today.
2.The first PCBs were funded by a music printing company.
Father of the Modern Printed Circuit Board, Paul Eisler escaped the Nazis, and he was an inventor from Australia. He worked at a music printing company and shared the idea with everyone of a new invention. And that was to make the first printed circuit board prototype. So, the company decided to invest in his idea. Today we see the results of his hard work as the prototype printed circuit boards.
3. No one knows why they’re still green.
The green material that is used on the layout of the PCB is a solder mask that’s visible through the glass. But nowadays technology has improved; solder masks are available in various colors. But the question remains that, why is the board still green then? Some people believe its story goes back to the military reigns and some also say that unlike that belief it was just about being uniformed. The companies just wanted stick to their idea of convention and continue with the original color. But then the legacy does continue and we stick to have the color green with us till date.
4. PCBs are vital in space travel.
Not a lot of people would know this, but as being an integral part of NASA’s space program, these circuit boards did help in getting the Apollo 11 astronauts to the moon and back safely. These boards are ideal for difficult electronics, given that they are light weight and need a very small amount of energy.
Although we live with an assumption that the technology we see and use today is brand new, the fact remains that they go long back in time and have a very fascinating history to them.
