Product Overview
Description
Product Description
Diamond/aluminum composite materials have the characteristics of high thermal conductivity, light weight and high strength. They are very suitable for the packaging of optoelectronic products with high thermal conductivity requirements, such as gallium arsenide (GaAs), gallium nitride (GaN), silicon carbide (SiC) and other second-generation and third-generation high-power semiconductor chip device packaging; they can replace the currently widely used Cu/W, Al/SiC and other materials.
