A printed circuit board (PCB) is a surface that can be either a single or a multilayer one where components of an electrical system are mounted. The components that can be made up of capacitors, resistors, and semiconductors are organized in a way that protects them, which is crucial due to how delicate they are. The organization of the components is also for the transmission of data input from one location that goes to another. PCBs come in many shapes and sizes since they are used for so many purposes. You will be able to learn even more about them when you continue reading the content detailed below.
The function of PCBs
Electrical components are situated in specific ways on the printed circuit boards in order for them to accomplish the data transmission necessary for their purpose. Along with the components, there are also lines made of copper that allow a charge to travel through the PCB and this causes the printed circuit board to cause power to flow where it is needed.
The different types of printed circuit boards
Since PCBs are used for so many applications, they come in many types. Some types of printed circuit boards available include:
Single-sided — A single-sided printed circuit board is one with a single layer of metal and substrate. The reason the PCB is called a single-sided one issue to all the components on the board being located on one side of the unit.
Double-sided — A double-sided PCB is anywhere there are holes in the PCB where the connections go through two sides.
Multilayer — With a multilayer printed circuit board, there will be at least three double-layered units that have been stacked with one on top of the other. This design will offer good insulation that helps with the transfer of heat in a manner that's safe for the PCB.
Aluminum-backed — An aluminum-backed printed circuit board is one where the commonly used fiberglass substrate is replaced instead by one that is aluminum. This option is chosen for things like electronics lighting.
Flex-circuit — A flex-circuit is a printed circuit board that is flexible. These are PCBs that can bend and move which is often needed when they are being used for different purposes where movement is required.
Rigid — Whereas a flexible printed circuit board will bend and move, a rigid one is a PCB that maintains its shape at all times. This is one that will be used when there is no need for any flexibility in the printed circuit board.
