PCB heat dissipation is one of the important factors to ensure stable operation and prolong life of electronic equipment. The following are some common methods and considerations for dealing with PCB heat dissipation:
Good Thermal Design: During the PCB design phase, it is key to consider a good thermal design. Arrange components and heat dissipation areas reasonably to avoid heat source concentration to reduce hot spots.
Heat dissipation area planning: According to the distribution of heat sources, divide the heat dissipation area and provide sufficient space for the heat dissipation area. This helps keep the temperature down and avoids heat sources interacting with each other.
Heat dissipation material selection: Select materials with high thermal conductivity, such as copper, as the base material of the heat dissipation layer or heat dissipation area to promote heat conduction and diffusion.
Heat dissipation layer design: Add a special heat dissipation layer, such as heat dissipation copper (Pour Copper) or heat dissipation pad, to increase the heat dissipation surface area and improve heat radiation and conduction.
Heat dissipation hole design: Set heat dissipation holes on the PCB, so that the heat can be transferred from the surface to the inside more easily, thereby improving the heat dissipation efficiency.
Heat sink: For components that require higher heat dissipation performance, heat sinks can be added to conduct heat away from the component to the surrounding air.
Fans and Heatsinks: When more cooling is required, consider adding a fan or heatsink. They improve cooling by forcing air flow.
Heat pipes: Heat pipes transfer heat from one area to another for more even heat distribution.
Avoid stacking: Avoid stacking multiple levels of components near heat sources to reduce temperature rise near heat sources.
Temperature Sensor: Install a temperature sensor to monitor the temperature on the PCB and take timely measures to prevent overheating.
Thermal simulation and simulation: Using thermal simulation and simulation tools, such as thermal simulation software, can help you predict and optimize the thermal performance of your PCB.
Testing and verification: After the design is completed, conduct thermal testing and verification to ensure that the actual temperature is within a safe range.

To make sure the actual temperature is within a safe range, thermal testing and verification should be performed after the design is complete.
