Unknown Facts about Printed Circuit Boards

In the last 100 years, Printed circuit boards have by far proven to be one of the most significant inventions. And nowadays there hardly does is an electronic device that does not hold a printed circuit board manufacturing in China, all do.

There may be a basic comprehension of a PCB among all about why is it installed and what does it do, but there are a few things about the same that not everyone talks or knows about as follow;

1) The very first printed circuit board was manufactured from brass and not copper. It was Charles Ducas in the early 1920’s who applied for a printed wire to the US patent office for it to travel from an electronic path directly to the insulated surface. This process was one of the earliest forms of electroplating, in which the ink passed electricity that was printed on the board. And since there was no option of installing copper wires because of lack of availability, the job was done by brass wires.

2) There were a few gramophones and tube radios that also had printed circuit boards installed in them. The PCB’s that we see today, the modern and high tech versions of them are not even close to the early 20’s circuit boards. But no matter how they look now or then, the fact remains that the existence has been since the time of gramophones and tube radios.

3) The original root of PCB’s come from the music printing industry. Paul Eisler, an engineer from the Vienna University of Technology, was considered to be the father of these all new modern looking printed circuit board. He had escaped the Nazis in 1936 and further gone over to join the music industry. And after he got a job he enlightened his co-workers with his idea of a printed circuit board, on which he had been working on for years. The company gave into his idea of invention and rest is the commendable history. 

4) The auto assembly process of the PCB was invented by the US army. It is the army signal corps who steals away the credits of manufacturing the process of auto assembly that further allowed them to make PCB’s at a much higher pace. It is the streamlining of the production of the printed circuit boards that have escalated the explosion of the products used by customers today.

5) If there were no printed circuit boards, there would have been no space travel possible yet. These PCB’s were a very important part of the space program held by NASA. It was the PCB that helped majorly in sending the Apollo 11 astronauts safely to the moon and brings them back sound as well. The area in the spacecraft is extremely confined and a PCB is of the lightest of weight and requires the least amount of electricity to work giving more space to all the other installations as well.

6) The spectrum is completely covered by the PCB makers. No matter what you need, flexible, rigid, aluminum printed circuit boards, everything is available today, from the simplest of boards to the most complex multi-layer one, everything.


So, whatever may the technology be mobiles, cameras, computers, players etc. printed circuit boards are everywhere and in every possible variety to meet individual needs.
