Polished 0.5mm 1mm 2mm Thick Si3n4 Ceramic Silicon Nitride Plate
Silicon nitride (Si3N4) is a man-made compound synthesized through several different chemical reaction methods. All Si3N4 ceramic parts are pressed and sintered by well-developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts a striking appearance.
Silicon nitride exceeds other ceramic materials in thermal shock resistance. It also offers an excellent combination of low density, high strength, low thermal expansion, and good corrosion resistance and fracture toughness.
silicon nitride has been used in a number of industrial applications, such as engine components, bearings, and cutting tools.
The Prime Characteristics
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/ºC) matches the semiconductor silicon material (3.5-4.0×10-6/ºC);
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 ºC to 200 ºC and then cool down, repeat 10000 times;
1. 10+ Years of manufacturing experience in OEM, ODM, and trusted & professional teams
2. Powerful R&D, prototyping & mass production capability to support trial order and high volume production
3. In-house comprehensive manufacturing types of equipment from raw materials to high precision machining
4. Rigorous quality control system and processes, including IQC, IPQC, QA, OQC in working instructions
5. Surpassing pre-sales, sales, and after-sales service abide all orders every customer as the first priority
