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.
