Silicon Nitride Ceramic Substrate

Silicon nitride ceramic substrate can be a plate with a thickness of about 0.5mm from the shape.

The basic requirements for silicon nitride ceramic substrates are:

1. Stable physical and chemical properties;
2. Reliable mechanical strength;
3. Consistent electrical parameters;
4. Lower heat transfer resistance.

The basic requirements for materials and processes:

1. There should be high-quality powder main materials and additive materials;
2. Mature powder grinding, batching, molding process and suitable formula;
3. Applicable air pressure sintering equipment and corresponding sintering process;
4. Double-sided precision grinding of large-size ceramic substrate;

The uses of silicon nitride ceramic substrate:

The coefficient of linear expansion of silicon nitride well match to semiconductor materials such as Si, SiC and GaAs, making silicon nitride ceramics an attractive substrate material for high-strength and thermally conductive electronic devices.

Circuit substrate:the past understanding is that the separate components are combine for circuits or integrated circuits and discrete components circuits are combine to form flat plate materials that meet the functional requirements of the overall circuit, and the circuit substrate make of two functional materials: insulation and conductivity.
