High thermal conductivity silicon nitride ceramic substrates are mainly used for the following purposes

High thermal conductivity silicon nitride ceramic substrate mainly has the following uses:

1. Electronic packaging substrate. The high thermal conductivity silicon nitride ceramic substrate has excellent thermal conductivity and can effectively dissipate heat. It is usually used to package power electronic devices with large heat generation, such as IGBT, thyristor, high-power LED, etc.

2. High temperature industrial furnace with battery pallet. The high thermal conductivity silicon nitride ceramic substrate can work for a long time above 1000°C, has excellent high temperature oxidation resistance and thermal shock resistance, and is often used for electrode support and fixation of high temperature industrial furnaces.

3. Laser thermal management components. High-power lasers generate a lot of heat, which requires an efficient thermal management system to discrete heat, and a high thermal conductivity silicon nitride ceramic substrate is used for thermal conduction and heat dissipation of the laser to ensure its normal operation.

4. Lamp holder and lamp holder. High-power lamps, such as halogen lamps and LED lamps, generate a large amount of heat and require high thermal conductivity ceramic substrates to dissipate heat and ensure the life and luminous efficiency of the lamps.

5. Laboratory work surface. High thermal conductivity silicon nitride ceramic substrate can be used as a laboratory worktable, direct contact with the test equipment, play a role in mechanical support and heat dissipation.

6. Vacuum chamber parts. High thermal conductivity silicon nitride ceramic substrates are usually used for supporting and connecting parts of various vacuum systems due to their high density and good air tightness.

7. High temperature electric furnace components. The high thermal conductivity silicon nitride ceramic substrate can be used to make heat shields, heating element supports, import and export parts, induction heating coil clamping frames, etc. of various high-temperature electric furnaces, and the working temperature is as high as 1500°C.

8. Quartz glass distillation unit components. It is used to connect the feed pipe and discharge pipe of quartz glass rectifier, which requires high thermal conductivity and high temperature resistance to chemical attack.

9. Semiconductor manufacturing equipment components. Equipment components used to manufacture semiconductors, such as wafer transfer line fixtures, reaction chambers, exhaust lines, etc., require high temperatures and chemical resistance.

In summary, high thermal conductivity silicon nitride ceramic substrates are widely used in electronic packaging, high temperature industrial furnaces, lasers, lamps, vacuum and chemical equipment and other fields due to their excellent thermal conductivity, high temperature chemical resistance and mechanical strength. It is an important high-performance industrial ceramic material.
