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.
It achieves fast and reliable welding results by utilizing the properties of aluminum foil and high molecular polymers.
Features and Principles The main features of aluminum foil polymer diffusion welding are fast and reliable.
It uses the high thermal conductivity of aluminum foil and the softenability of high molecular polymer to complete the welding connection in a short time.
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.
The aluminum foil quickly conducts heat to the welding joint, allowing the joint to quickly reach the welding temperature.
2. Softening properties of high molecular polymers: High molecular polymers will soften at a certain temperature, thereby forming a strong connection with other materials.
The thermal conductivity of aluminum foil is used to make the polymer reach the softening temperature and achieve diffusion connection between contacts.
