Overview
Specification
FAQ

Electronic substrates are the main circuit board substrates and are widely used in the electronics manufacturing industry.


Silicon nitride electronic substrates are mainly used for their insulation and thermal conductivity. Ultra-large-scale integrated circuits and electronic chips have higher and higher requirements for insulation and heat dissipation due to their large amount of computing and high heat generation. Silicon nitride electronic substrates can solve this problem.


Made of silicon nitride ceramic, using a special formula and process, each substrate is sintered at 2000°C, with a thermal conductivity of >80W/(m*k). It has passed the quality inspection of international leading companies and the size can be customized according to customer needs.

What are the advantages of Silicon Nitride?

Compared with other technical ceramics, the low thermal expansion coefficient of Silicon Nitride provides good thermal shock resistance. It is extremely hard, fracture-tough, surpasses the high temperature capabilities of most metals, and also has a superior oxidation resistance. As a consequence, silicon nitride can withstand the toughest conditions in the most demanding high-temperature and high-load applications.

What is the formula for Silicon Nitride?

The formula for silicon nitride is Si3N4.
