The main features of the Si3N4 ceramic tray
1. High thermal conductivity ( up to 70 W/m.k), 3 times that of alumina ceramic substrate;
2. The thermal expansion coefficient (3.1×10-6/℃) matches the semiconductor silicon material (3.5-4.0×10-6/℃);
3. The bending strength is higher than that of the alumina substrate, which is twice that of the alumina substrate;
4. Excellent electrical performance, with extremely high insulation resistance and low dielectric loss;
5. The compatibility of circuit materials is good, and multi-layer wiring can be performed to achieve miniaturization of the package;
6. High thermal shock resistance, from 0 ℃ to 200 ℃ and then cool down, repeat 10000 times;
7. Chemical resistance, resistant oxidization, acid, alkali corrosion, service life-span up to 10 years.
The description of the Si3N4 ceramic tray
Silicon nitride ceramic is an inorganic material ceramic that does not shrink when sintered. Silicon nitride is very strong, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, and high-temperature resistance.
Si3N4 ceramic is a covalent bond compound. The basic structural unit is a [SiN4] tetrahedron. The silicon atom is located at the center of the tetrahedron. There are four nitrogen atoms around it, which are located at the four vertices of the tetrahedron, and then every three A tetrahedron shares the form of an atom, forming a continuous and robust network structure in three dimensions.
