What Is Printed Circuit Board (PCB)?

You know that thing you're doing right now? Yeah, that's a PCB. If you need to figure out what a PCB is, it's the printed circuit board you're holding. It's a thin piece of plastic with tiny copper wires embedded in it and all over it, and those wires connect different parts of your computer—like your CPU, RAM, GPU, and hard drive—so they can talk to each other. It makes your computer work! It lets you use this website without crashing your computer every few seconds. PCBs are the secret sauce of your favorite gadgets. They aren't the glamorous part of your phone or computer, but they allow all the other components to work together. PCBs consist of layers of non-conductive materials, like fiberglass and plastic, which hold copper circuitry for all your devices' electronics. The layers are assembled on top of each other, then printed with conductive pathways connecting all your device parts. Some PCBs can also be programmed to hold different functions, depending on the user's needs. A user can order a fully functional custom-built PCB or buy a prefabricated one that Can use can use right out of the box. Depending on the nature of the electronic components that it holds, a PCB may have different levels of durability and reliability. Some are more prone to failure than others. Precautions should be taken when using a PCB, as they can be dangerous if misused. If you've been using a computer for over a few minutes, you've probably come into contact with PCBs. PCBs are found in nearly every electronic and computing device, including motherboards, network and graphics cards, and internal circuitry in hard/CD-ROM drives. You can only make a simple cup of tea by running into them: PCBs are also used in the heating elements of kettles and electric water heaters. And that's not all: they're also used in many medical devices! PCBs are everywhere!
