summary
Medium high temperature silver pasteIt is a commonly used material in the manufacturing of high-temperature electronic components, with excellent conductivity and thermal conductivity, which can effectively dissipate heat, improve the service life and stability of components. This article will introduce the composition, preparation process, performance characteristics, and application fields of medium high temperature silver paste.
form
Medium high temperature silver paste is mainly composed of silver powder, organic components, and high-temperature stabilizers. Among them, silver powder is
Silver pasteThe main component of it has high conductivity and thermal conductivity, and is not easily oxidized in high temperature environments. Organic components are stabilizers for silver paste, which can improve the adhesion and stability of silver paste. High temperature stabilizers are designed to improve the stability and corrosion resistance of silver paste in high-temperature environments, thereby ensuring the stability and reliability of electronic components.
Medium high temperature silver pasteThe preparation process includes steps such as selecting silver powder, adding organic components, stirring and mixing, filtering, and drying. Among them, the selection of silver powder is a key step, and different particle sizes and shapes of silver powder should be selected according to different application requirements. The amount of organic components added should be adjusted according to the requirements of silver powder adhesion and stability. The mixing process should ensure the uniform dispersion of silver powder and organic components. During the filtration process, attention should be paid to the accuracy of the filter to avoid impurities in the silver paste. The drying process should control the temperature and time to avoid clumping or layering of silver paste during the drying process.
Performance characteristics
High temperature silver paste has the advantages of good electrical conductivity, thermal conductivity, high temperature resistance, and corrosion resistance. Its conductivity can reach 10 ^ 4~10 ^ 5 S/cm at room temperature, and it can still maintain high conductivity in high temperature environments. Its thermal conductivity is also very excellent, which can quickly dissipate heat, improve the stability and service life of components. In addition, medium high temperature silver paste also has good adhesion and stability, which can be maintained on the surface of components for a long time and is not easy to peel off.
application area
Medium high temperature silver paste is widely used in the manufacturing of electronic components, such as transistors, power modules, LEDs, etc. Among these components,
Silver pasteMainly used for electrode preparation and coating of heat dissipation materials. In addition, silver paste can also be used in fields such as solar panels and printed circuit boards, with broad application prospects.
conclusion
Medium high temperature silver paste is a high-performance electronic component material with excellent conductivity and thermal conductivity, which can improve the service life and stability of components. The preparation process and application fields of silver paste are also very extensive, providing important support for the manufacturing of electronic components.
