What is PCB?


PCBmanufacturerChina:talk Printed circuit boards (PCBs) are the boards that are used as the base in most electronics – both as a physical support piece and as the wiring area for the surface-mounted and socketed components.PCBs are most commonly made out of fiberglass, composite epoxy, or another composite material.


Most PCBs for simple electronics are simple and composed of only a single layer.More sophisticated hardware such as computer graphics cards or motherboards can have multiple layers, sometimes up to twelve.


Although PCBs are most often associated with computers, they can be found in many other electronic devices, such as TVs, Radios, Digital cameras and Cell phones.In addition to their use in consumer electronics and computers, different types of PCBs are used in a variety of other fields, including:


• Medical devices.

• Industrial machinery.

• Lighting.

• Automotive and aerospace industries.

Single-layer PCB

A single-layer or single-sided PCB is one that is made out of a single layer of base material or substrate.One side of the base material is coated with a thin layer of metal.Copper is the most common coating due to how well it functions as an electrical conductor.Once the copper base plating is applied, a protective solder mask is usually applied, followed by the last silk-screen to mark out all of the elements on the board.




Double-layer PCB

Double-layer or double-sided PCBs have a base material with a thin layer of conductive metal, like copper, applied to both sides of the board.Holes drilled through the board allow circuits on one side of the board to connect to circuits on the other.




Multi-layer PCB

Multi-layer PCBs consist of a series of three or more double-layered PCBs.These boards are then secured together with a specialized glue and sandwiched between pieces of insulation to ensure that excess heat doesn't melt any of the components.Multi-layer PCBs come in a variety of sizes, going as small as four layers or as large as ten or twelve.The largest multi-layer PCB ever built was 50 layers thick.



Rigid PCB

Rigid PCBs are made out of a solid substrate material that prevents the board from twisting.Possibly the most common example of a rigid PCB is a computer motherboard.The motherboard is a multilayer PCB designed to allocate electricity from the power supply while simultaneously allowing communication between all of the many parts of the computer, such as CPU, GPU and RAM.


Rigid PCBs make up perhaps the largest number of PCBs manufactured.These PCBs are used anywhere that there is a need for the PCB itself to be set up in one shape and remain that way for the remainder of the device's lifespan.Rigid PCBs can be anything from a simple single-layer PCB all the way up to an eight or ten-layer multi-layer PCB.

All Rigid PCBs have single-layer, double-layer or multilayer constructions, so they all share the same applications.
