Thermal Conduction

Thermal conductivity promotes the transfer of thermal energy via conduction from one area to another. This phenomenon is useful for any heat transfer process. Typically, coatings of aluminum or copper are used to enhance thermal conductivity and help ensure even heat distribution.

Solutions:

The deposition of a copper coating on an aluminum heat sink enhances its ability to quickly conduct heat away from an electronic part. In addition, it provides a solderable surface for the attachment of electrical leads.
