Thermal Management Grade CVD

Thermal Management Grade CVD

Overview

Diamond has thermal conductivity five times that of copper while being an electrical insulator, making it the perfect heat sink material. The unsurpassed thermal conductivity combined with high electrical resistivity enables increased microprocessor frequency, higher output power delivery, smaller device dimensions, and extended component lifetimes.
