Thermal spraying technology MLCC capacitor

Vetek semiconductor’s new technology-thermal spraying technology MLCC capacitors are with good quality, competitve price.

Below is the thermal spraying technology:

1.Thermal spraying technology can effectively improve the high temperature resistance of the crucible. The sintering process of MLCC capacitor materials is usually carried out in a high temperature environment, and the crucible must be able to withstand extremely high temperatures without deformation or performance degradation. By spraying a layer of high melting point materials such as aluminum oxide, zirconium oxide, etc. on the surface of the crucible, thermal spraying technology can significantly improve the high temperature resistance of the crucible and ensure that it maintains stable and reliable performance during high temperature sintering.

2. The enhancement of corrosion resistance is also a key role of thermal spraying technology in crucible coating. During the sintering process, the material in the crucible may produce corrosive chemicals, causing corrosion on the crucible surface. This corrosion will not only shorten the service life of the crucible, but may also cause material contamination, thereby affecting the performance of the MLCC capacitor. Through thermal spraying technology, a dense anti-corrosion coating can be formed on the surface of the crucible, effectively preventing corrosive substances from eroding the crucible, extending the service life of the crucible, and ensuring the purity of the MLCC material.

3. Thermal spraying technology can also optimize the thermal conductivity of the crucible. During the sintering process of MLCC capacitor materials, uniform temperature distribution is essential to obtain the ideal sintering effect. Through thermal spraying technology, materials with high thermal conductivity, such as silicon carbide or metal-ceramic composite materials, can be coated on the surface of the crucible to improve the thermal conductivity of the crucible, so that the temperature can be more evenly distributed throughout the crucible, thereby ensuring uniform sintering of the material and improving the overall performance of the MLCC capacitor.

4.Thermal spraying technology can also improve the mechanical strength of the crucible. During high-temperature sintering, the crucible needs to bear the weight of the material and the stress caused by temperature changes, which requires the crucible to have high mechanical strength. By thermal spraying the crucible surface, a high-strength protective coating can be formed to enhance the compressive strength and thermal shock resistance of the crucible, thereby reducing the risk of damage to the crucible during use and improving its service life and reliability.

5. Reducing the contamination of materials in the crucible is also an important role of thermal spraying technology. During the sintering process of MLCC capacitor materials, any tiny impurities may affect the performance of the final product. By using thermal spraying technology, a dense and smooth coating can be formed on the crucible surface, reducing the reaction between the material and the crucible surface and the mixing of impurities, thereby ensuring the purity and performance of the MLCC capacitor material.
