Indispensable spherical quartz powder material in electronic packaging

Spherical quartz powder summary
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.

How to prepare spherical quartz powder spherical SiO2?
Spherical quartz powder is made of natural quartz stone after purification and ultra-fine grinding, and it is made through a certain high temperature field. Its phase, crystal and shape will change instantly, from solid to molten to solid, from crystal to amorphous The state changes from irregular angular particles to regular spherical particles, which are then made of powder. Current preparation methods include high temperature plasma melting method, high temperature melt injection method and gas combustion flame method.

Application of Spherical Quartz Powder
Spherical Quartz Powder Spherical SiO2 is mainly used for high temperature vulcanized silicone rubber, silicone defoamer, advanced printing ink, powder coating, PVC resin, unsaturated polyester resin thickener, thixotropic agent, drug powder, sheet preparation, cosmetics Wait.
Spherical silica powder not only has good shape, but also has high chemical purity and low content of radioactive elements. It can meet various technical requirements in high-end integrated circuits. Its application can greatly reduce the thermal expansion coefficient of packaging materials and reduce the thermal expansion coefficient of packaging materials. Dielectric constant, reduce stress, greatly improve rigidity and abrasion resistance, weather resistance, impact resistance, compressive strength, tensile strength, wave resistance, flame retardancy, so that the product has good arc resistance insulation properties and resistance to ultraviolet radiation Sex, etc., has become an indispensable key material in electronic packaging.
Spherical quartz powder is mainly used in the field of electronic packaging. It is also widely used in the precision grinding of electronic inks, optical fibers, high-end cosmetics, advanced precision ceramics, optical devices and electronic components, and as a filler for special paints and coatings.
