Thermal Grade

Product Introduction

Based on the low coefficient of thermal expansion and the highest thermal conductivity at room temperature, the single crystal CVD diamond has two main thermal applications: 1) centralized heat dissipation of large areas, such as TR components, microwave power components and high power laser components; 2) point heat dissipation for thermal emission units, such as Gallium nitride(GaN) devices.
