How to solve the overheating of PCB chip?

When the chip on PCB is overheated, some measures need to be taken to solve the problem. Here are some possible solutions:

1. Improve heat dissipation efficiency: ensure that the radiator and heat dissipation fan around the chip work normally, and remove dust or blockage that may affect heat dissipation. We can consider increasing the number or size of radiators and increasing the speed of cooling fans to improve the cooling effect.

2. Improve PCB design: optimize PCB layout and copper wire to improve heat dissipation effect. Optimize the heat conduction path to make it as short as possible to reduce the transmission distance of heat on PCB. Arrange the position of the chip and capacitor reasonably to avoid the hot spots being concentrated in one place.

3. Use high thermal conductivity materials: For example, replacing ceramic materials with better heat dissipation, such as aluminum nitride ceramic substrates, is now a very mature process, such as Sliton ceramic substrates.

4. Reduce the circuit load: check and optimize the circuit power consumption, reduce the circuit load and reduce the working temperature of the chip.

5. Improve ventilation conditions: ensure that there is enough space around the PCB to ensure air circulation and avoid excessive local temperature.

6. Check the power supply: ensure the stability of the power supply. Voltage fluctuation or unstable power supply may cause the chip to overheat.

7. Check the working state of the chip: If the chip is not working properly, it may lead to overheating. Check whether the chip is damaged or faulty, and repair or replace it in time.

Please note that if the chip continues to overheat and cannot solve the problem, it is recommended to consult professional technicians or contact the chip manufacturer for further help and guidance.
