Product Description
Thin Film Si3N4 Silicon Nitride Substrates
Product Overview
These advanced ceramic substrates are engineered specifically for power electronics applications, offering exceptional thermal, mechanical, and electrical properties in a compact thin-film format.
Key Performance Advantages
- Extreme weather resistance - unaffected by sunlight, rain (including acid rain), or moisture
- Superior UV resistance - color stability meets international gray level 4-5 standards
- Thermal stability - maintains properties and appearance through rapid temperature changes
- High impact strength - optimal combination of bending strength and elasticity
- Easy maintenance - dense surface prevents dust adhesion, requires no protective coatings
- Excellent fire resistance - does not melt, drip, or explode; maintains long-term stability
