How to prevent PCB failure or performance degradation due to overheating?

In PCB design, electronic components generate heat when current passes through them, and the amount of heat depends on factors such as power, electrical equipment characteristics, and circuit design.

To prevent failure or performance degradation, designers strive to create boards that stay within safe temperature ranges. While some circuits can operate without additional cooling, in certain cases a heat sink, cooling fan, or a combination of mechanisms may be required. Therefore, we will now focus on manufacturing practices to better control and reduce board temperature.

The following issues should be considered when designing a circuit board:

1. Performance data and component size: When designing a printed circuit board, you need to consider the performance data and component size to better manage heat.

2. Main heat dissipation components: Understand which components will generate more heat and determine the best heat dissipation mechanism. This information can usually be obtained through the manufacturer's data sheet.

3. PCB size: The size of the PCB directly affects its heat dissipation performance and needs to be carefully considered.

4. PCB component materials, layout and placement: The material, layout and placement of PCB components have an important impact on heat dissipation performance.

5. Placement of peripheral devices: Reasonable arrangement of the location of peripheral devices can help improve the overall heat dissipation effect.

6. Application environment temperature: Consider the temperature of the application environment to ensure that the circuit board can work normally under various environmental conditions.

7. Heat dissipation: Determine the specific amount of heat that the circuit board needs to dissipate.

8. Appropriate cooling method: Select the appropriate cooling method according to actual needs, such as cooling fan, heat sink, etc.

Best practice is to optimize temperature at the component level based on the operating environment.
