Spherical quartz powder is made of carefully selected irregular-angled silicon micropowder as a raw material, and processed into a spherical shape by flame melting method to obtain a spherical silica powder material with small specific surface area, good fluidity and low stress.
Spherical Quartz Powder Properties
Spherical quartz powder has excellent properties such as smooth surface, large specific surface area, high hardness and stable chemical properties.
First of all, the spherical powder has good fluidity and is evenly mixed with the resin to form a film. The resin addition is small, the quartz powder filling amount is high, and the mass fraction can reach up to 90.5%. The higher the filling amount of quartz powder, the lower the thermal conductivity, and the smaller the thermal expansion coefficient of the molding compound. The closer to the thermal expansion coefficient of monocrystalline silicon, the better the performance of the electronic components produced.
Secondly, the stress of the spherical powder is only 60% of the stress of the angular powder, and the plastic molding compound made of spherical quartz powder has the least stress concentration and the highest strength.
Finally, the spherical powder has a smooth surface, low friction coefficient, and low wear on the mold, which can prolong the service life of the mold by more than one time.
Spherical Quartz Powder Applications
Spherical quartz powder has a wide range of applications, and its use as an electronic packaging material is the largest market for its application. Electronic packaging is the supporting industry of integrated circuits. With the development of large-scale and very large-scale integrated circuits, integrated circuits are becoming more and more sophisticated, and the requirements for packaging materials are getting higher and higher, and the packaging forms are continuously optimized and updated.
In microelectronic packaging, it is mainly required to have high moisture resistance, low stress, low alpha radiation, resistance to dip soldering and reflow soldering, and good plastic sealing performance after the integrated circuit is packaged. As an important support material for EMC, spherical quartz powder not only requires its particle size to meet the specific range of packaging, but also requires its high purity and low content of radioactive elements, especially the spherical shape requirements for the particle shape.
In addition to being mainly used in the field of electronic packaging, spherical quartz powder can also be widely used in the manufacture of electronic inks, optical fibers, high-grade cosmetics, high-grade precision ceramics, precision grinding of optical devices and electronic components, and as fillers for special paints and coatings.
