MSE 2090: Introduction to Materials Science Chapter 19, Thermal Properties 14 Mechanisms of heat conduction Heat is transferred by phonons (lattice vibration waves) and electrons. The thermal conductivity of a material is defined by combined contribution of these two mechanisms: k =kl +ke where kl and ke are the lattice and electronic thermal Aluminum Based Copper-clad Laminate Sheet Description and Application Aluminum base copper-clad laminate have excellent flame retardant, high mechanical strength, dimensional stability etc. Especially it has very good heat sink, electromagnetic shielding and solder float. It’s widely used for the modifier and sparker on fire for
