A PCB (or printed circuit board) is what ties together all the different parts of your computer. If the PCB fails, then your computer completely stops working or becomes unusable. You may wonder what exactly a PCB does and why it matters that it should be a strong one.
What is a PCB?
A Printed Circuit Board (PCB) is the plate on which you mount all of the components of your PC, like the RAM and CPU. It’s an essential part of any computer because it provides structural support for all of your components, hence being.
Printed Circuit Boards Provide Structure
The most obvious reason for a strong PCB is that it provides structure to your computer. If your motherboard is weak, then so will all other components around it. A good quality PCB will be made from high-grade materials such as FR-4, which can withstand constant use and exposure to heat, chemicals, and moisture.
Strong PCBs Are Durable
If you’ve ever seen a computer motherboard up close, you probably noticed that it has numerous copper lines etched on its surface. These copper lines are the electrical pathways that connect all the components in your computer. Each component connects to the next via soldering points.
These components and connections can be damaged if they aren’t protected correctly. For example, when the motherboard is exposed to extreme heat or cold or when it’s subject to mechanical shock, it can cause damage to both the components and their connections. A weak PCB will make a computer more susceptible to damage from environmental hazards.
A Strong PCB Is Heat-Resistant
All those advanced circuits are delicate and can be damaged by heat. This is why you’ll see the PCBs covered with a layer of plastic or resin designed to protect them from damage caused by heat.
Unfortunately, heat is hard to control for a number of reasons. A poorly designed computer case might allow too much heat to build up inside or restrict airflow through the case. Using too many fans or making other changes to your PC can also cause temperatures to rise inside your case, which will have an impact on your PCB if it is not properly protected.
The quality of the PCB may not be an issue that bothers a lot of computer users, but it should. It is one of the most important parts of your computer, even though you might never see it. The PCB works very hard to ensure that everything works smoothly inside your computer, and it is vital to have one that is strong and durable.
