PCB as an electrical component, its heat dissipation is very important, once a problem occurs, the entire machine will be paralyzed. Therefore, heat dissipation is a key issue to tackle when it comes to PCB, otherwise, it will cause damage to other electrical appliances and reduce life span.
The main heat sources of PCB come from the heat of electronic components, the PCB itself, and the heat transferred from other parts. Among them, the components have the largest heat generation. At the design stage, it is necessary to include thermal management in particular the distribution of components and the design of the circuit board.

How to Remove Heat from PCB Boards
There are several techniques that designers can use to remove heat from components and PCBs. The common mechanisms include heat sinks, cooling fans, and heat pipes, Most likely, circuits generate more heat that requires more than one technology. For example, cooling a laptop processor and display chips requires a heat sink, heat pipe, and a fan.

A heat sink is a thermally conductive metallic part with a large surface area, usually attached to components such as power transistors and switching devices. A heat sink allows the component to dissipate its heat over a larger area and transfer that heat to the surroundings. In some cases, such as high current power supplies, adding a cooling fan aids in faster and better heat removal.

It is a cooling solution for Printed Circuit Boards (PCBs), which components are generally soldered onto the PCB to both electrically connect and mechanically fasten to them. It is light-weighted and easily soldered or inserted by clips, nuts or adhesive thermal pads onto the Printed Circuit Boards (PCBs), the most cost-effective solution for heat dissipation.
