The Printed Circuit Board And Its Uses

Posted By Paige Chen

In the society today, people are dependent on their gadgets and home electronics to help ease hassles of daily life. Only few people know that inside these electronics, there is a “brain” which controls each function of machinery. In electronics, the printed circuit board is in charge of individual functions. The PCB fabrication method paved the way to mass produce gadgets and electronics and perform many functions.

Printed Circute bordAs technology progresses, people needed to devise ways to make the production of printed circuit boards faster. Through the use of computer-assisted design software, computer engineers are now able to design complicated PCBs without having to draw each layout manually. Now, factories can produce hundreds of electronics without having to manually solder each electronic component.

In a single device, there are usually more than five PCB. This is because a single PCB can only perform one function and because of the state-of-the-art features in electronics today, most PCBs are designed in a complex manner.

In this article, the printed circuit board, its uses and a bit about PCB fabrication will be discussed.

Have you ever dissected a cellular phone or any electronic device? Inside these things, you will find green boards that have electronic components such as capacitors and transistors. Each component is soldered carefully into the board which is made up of insulating materials to hold them together. On the board, there are also copper layers used as substrates to conduct electricity as they connect the electronic components together.

To know more about the printed circuit board and PCB fabrication, this article will be providing examples of its different uses.

It is widely known that printed circuit boards are used inside computers to take care of its processes. The brain of the computer, which is the motherboard, is actually a PCB that contains the main electronic components to make the computer run. The motherboard holds the components of the central processing unit and the memory of the whole system. Without this, the computer will not be able to work at all.

Through the use of electronic pathways, the motherboard is also connected to other printed circuit boards such as the video card, graphics card and sound card. Some people do not know that even the Random Access Memory, or simply RAM, is also a PCB that stores the temporary memory of the computer to make it run faster. These PCBs used in computers become more complex as the specsupgrade. Instead of a single copper layer used, the PCB would contain multiple layers connected to each other.

The brains of cellular phones also undergo PCB fabrication. Have you noticed that each year, newer models with better features are introduced to the market? This would mean that more complex PCBs are also introduced. PCB are installed in cellular phones to control the backlight, keypad and also the main system of the cellular phone. Even if the phone is not a smart phone, each process still takes place in its main PCB to send messages and place calls.

In home electronics, there are also printed circuit boards to control each function. As an example, when you look inside a microwave, behind the keypad lies the PCB which has the transistor which controls the on and off switch. The espresso machine also has a PCB to tell the machine the settings you punch in. Basically, anything that would require electricity to run has a PCB behind it.

As the inventions and innovations keep on coming, there would be more complex printed circuit boards to be developed by computer engineers. There is still a lot of untapped potential in the world of the printed circuit boards. Who knows, with a little more time, these PCBs could be enhanced to create something spectacular.
