High temperatures have a continuous effect on electronic products: degradation of insulation; damage to components; thermal aging of materials; cracking of low melting point solder joints and solder joints falling off. Devices will fail due to overheating, and the reliability of electronic devices will be reduced. (High operating temperature of electronic products will not only reduce its service life and reliability, but also cause degradation of insulation, component damage, thermal aging of materials, cracking of low melting point welds and solder joints falling off)
