A PCB assembly is a printed circuit board used for many different applications. While achieving wide popularity only in the 1960s, these days, a PCB assembly is a component of almost anything electronic or computerized by nature. And do not be surprised when you hear the term PCBA thrown around.
It means essentially the same thing as the PCB version. How did the PCB assembly become so popular, in the first place? Well, first of all, the electronic device makes electronic or electrical circuitry a lot less cumbersome. In fact, if the device was not invented, a lot of complicated wiring would still be in use just to make things work from microwave ovens to cars and super computers.
So you can only imagine how much wiring is saved when a PCB is utilized instead. The setup likewise ensures that connections, whether electrical or electronic by nature–are never compromised or end up influencing each other in any manner. And that is why, the PCB is known for so-called discrete connections.
Another major advantage of the assembly over electrical components is that of course, the former is easier to manufacture. Silk screen printing and simple soldering both make for less time consuming production. This means more savings for any business out there.
Still cannot figure out in your head what a PCB is all about? Well here goes: the motherboard of a computer is a perfect example of a PCB.
All that green stuff with hints of copper all work together to ensure connectivity of electricity, electrons, and of course, data. And if you are afraid that maybe this kind of circuitry might run out soon, just consider this. Majority of the materials used in the operation of the device comes from silica or sand.
With sand so pervasive in our planet, it is rather comforting to know that continuous production is assured for many, many years to come. As for copper, though, which is an important component of the device in question–supply and demand is far from assured. The copper is used in an integrated circuit (IC) to interconnect components.
So if you see copper on the IC layout, that means that there is where connection is intended to happen by design. Thanks to such an amazing invention, so much electricity is being saved. So in away, the extensive use of integrated circuits is indirectly contributing to power conservation. At the same time, circuits of this kind as opposed to wires–ensure lesser chance for electrocution happening. And you know what? By this time, the world PCB market has grown to as much as $70 billion with estimates closer to $80 billion by the year 2024.
