Why SmCo magnets are used in SMT fixtures

  Firstly, SmCo magnets have a high magnetic energy product, which means that they can generate a relatively strong magnetic field in a relatively small volume. In SMT fixtures where certain requirements are placed on the spatial layout, a compact and powerful magnetic field source is of crucial importance. It can accurately attract tiny electronic components and ensure the fixed position of the components during the chip mounting process, thereby improving the mounting accuracy and efficiency.

  Secondly, its excellent temperature stability plays a key role. During the SMT processing, the soldering process will generate relatively high temperatures. For ordinary magnetic materials, their magnetism is prone to attenuation under high temperatures, resulting in a decrease in the adsorption force and affecting the fixing effect of the components. However, SmCo magnets can withstand high temperatures and still maintain a stable magnetic force even in the high-temperature environment of soldering, ensuring the normal operation of the fixtures and reducing the defective product rate caused by temperature factors.

  Furthermore, SmCo magnets have strong chemical stability and are not easily oxidized or corroded. The environment in an SMT production workshop is complex, and there may be various chemicals, moisture, etc. SmCo magnets can resist these adverse factors, have a longer service life, reduce the cost of frequently replacing fixture components, and ensure long-term stable production.

  Finally, its high coercive force characteristic makes the magnets less likely to undergo demagnetization in the presence of external interfering magnetic fields. In an SMT workshop where there are numerous electronic devices and the magnetic field environment is complex, this characteristic ensures that SmCo magnets always stably exert their magnetic force, laying a solid foundation for the reliable operation of SMT fixtures.
