Product Description

Insulator Ceramic Al2O3 Alumina and AlN Aluminum Nitride Ceramic Substrates

Laser Diode (LD) Modules

Consumer Electronics (Smartphones/Tablets)

Premium Aluminum Nitride Sheets - Superior Thermal Conductivity & Electrical Insulation.

A high-performance ceramic solution for consumer electronics, our Aluminum Nitride (AlN) Ceramic Substrate addresses thermal issues in compact devices.

As smartphones, tablets, and wearables pursue miniaturization and high performance, thermal management has become a critical factor restricting user experience.

Our thin-film AlN ceramic substrate offers exceptional thermal conductivity in a compact form, dissipating heat from processors and power management chips.

Choose our AlN ceramic substrate to enhance device performance, reduce overheating risks, and gain a competitive edge.

Application 
Aluminum Nitride Sheets – Key Applications:
1.LED Industry: Heat sink substrates for high-power LED chips, improving luminous efficiency and lifespan. 
2.Power Electronics:  Insulating substrates for IGBT modules, SiC/GaN devices, and automotive power control units.
3.Semiconductor Packaging: Chip carriers and package bases for high-frequency and high-reliability ICs. 
4.RF & Microwave Circuits: Low-loss substrates for 5G communications, radar systems, and satellite components. 5:Industrial & Automotive
Heat spreaders in EV battery systems, laser diode coolers, and high-temperature sensor housings.
