Deso engineers say that the contact surface of the SMA plug needs to be ground and polished to improve its surface finish. High-finish surfaces can reduce contact resistance and improve electrical conductivity, thus ensuring the stability and reliability of signal transmission. At the same time, the high-finish surface can also reduce oxidation and corrosion, extending the life of the plug.
During production and use, some defects may occur on the surface of SMA plugs, such as scratches, pits, bulges, etc. These defects can affect the contact performance and signal transmission quality of the plug and therefore require grinding and polishing to remove. By removing surface defects, the electrical performance and reliability of the plug can be ensured.
After grinding and polishing, the SMA plug surface can form a mirror effect, smooth as a mirror, and this surface can improve the conductivity and signal transmission quality of the plug. At the same time, the mirror effect can also improve the appearance of the plug and make it more in line with market demand.
The purpose of coarse grinding is to remove large defects and protrusions on the surface of the SMA plug and lay the foundation for subsequent fine grinding and polishing. At this stage, coarser abrasives and larger grinding forces are used to smooth the surface quickly. The rough grinding process may use materials such as corundum, which has a high hardness and smooths the surface quickly.
The purpose of fine grinding is to create smaller wear marks on the surface of the SMA plug in preparation for the polishing stage. At this stage, finer abrasives and less grinding forces are used to make the surface smoother. The fine grinding process may use materials such as silicon carbide, which are hard and wear-resistant, effectively smoothing surfaces.
The purpose of polishing is to make the surface of the SMA plug smooth as a mirror, improving its conductivity and signal transmission quality. At this stage, the surface is polished with a polishing cloth and polishing agent to achieve a mirror effect. Methods such as mechanical polishing or chemical polishing can be used in the polishing process, and the appropriate polishing agent and polishing process can be selected according to the specific situation.
Through grinding and polishing, the roughness and unevenness of the surface of the SMA plug are removed, and its surface finish is improved. This helps to reduce contact resistance, improve electrical conductivity, and ensure stable and reliable signal transmission.
During production and use, defects such as scratches, pits, and bulges may occur on the surface of SMA plugs. The grinding and polishing process can effectively remove these defects and ensure the electrical performance and reliability of the plug.
Through grinding and polishing, the surface of the SMA plug is smooth as a mirror, forming a mirror effect. This surface can improve electrical conductivity and signal transmission quality, while improving the aesthetics of the plug to meet market demand.
The surface of the ground and polished SMA plug has higher hardness and wear resistance, and can withstand multiple plugging and unplugging and long-term use. This helps to improve the contact reliability of the plug and extend its service life.
The grinding and polishing process can reduce impurities and contaminants on the surface of SMA plugs, reduce contact resistance, and improve electrical conductivity. This helps to ensure that the electrical performance of the plug complies with the relevant standards and specifications.
With the continuous development of wireless communication and radio frequency technology, the market has higher and higher requirements for the electrical performance, appearance quality and reliability of SMA plugs. Through the grinding and polishing process, plug manufacturers can meet these needs of their customers and improve the market competitiveness of their products.
