What is spherical Quartz Powder?
Spherical quartz powder is characterized by its smooth surface, high hardness, and stable chemical properties. First, the spherical material is very fluid and can be mixed evenly with resin to form an even layer. Although the resin used is minimal, the quartz powder filling volume can be high. It can also reach up to 90% mass fraction. The thermal conductivity of the molding compound will be lower if the quartz powder is used as a filler. The performance of electronic components that are produced is better when they are close to monocrystalline silicon’s temperature expansion coefficient. Second, the stress of the cylindrical powder is only 60% lower than the stress of angular powder. Furthermore, the plastic molding compound made with spherical Quartz powder has the lowest stress concentration, as well as the highest strength. Finally, the spherical material has a smooth, low friction coefficient and wear on the mold which can increase the mold’s life expectancy.
Spherical quartz powder’s main applications
There are many uses for sphered quartz powder. Electronic packaging is the biggest market in this application area. Electronic packaging is the support industry for integrated circuits. As integrated circuits become more complex, the requirements for packaging materials are rising. In order to keep up with this, packaging forms are continually optimized and updated. The main materials for electronic packaging include substrate materials, plastic materials, lead frames, and solder. Plastic packaging has grown rapidly because of its simplicity, cost-effectiveness, and ability to be mass-produced. Plastic packaging is responsible for 95% global integrated circuits market.
Spherical silica powder is not only beautiful in form, but also has high chemical purity. It can be used to meet the technical requirements of high end integrated circuits. The heat expansion coefficient and dielectric constant of plastic packaging compounds can be greatly reduced by the use of earth. The earth increases the product’s rigidity and abrasion resistance. It also reduces impact resistance, weather resistance. compression resistance, moisture resistance and flame resistance. This makes it an essential key material for electronic packaging. Additionally to its main use in the field electronic packaging, spherical Quartz powder can be used extensively in the manufacture and processing of high-grade optical inks, optical fibres, high quality precision ceramics, precision grinding optical devices and electronic parts, as well as in filler materials for special paints or coatings.
