Aluminum foil polymer diffusion welding: an efficient method for connecting high-power devices Aluminum foil polymer diffusion welding is an efficient welding method commonly used to connect high-power devices.

The specific principles are as follows: 1. Aluminum foil conducts heat quickly: Aluminum is a metal with good thermal conductivity, and its thermal conductivity is much higher than common metals such as copper and iron.

2. Softening properties of high molecular polymers: High molecular polymers will soften at a certain temperature, thereby forming a strong connection with other materials.
