What Advantages does Spherical Silica Powder Have?

What Is Silica Powder? Silica Powder is made from pure quartz.

Silica is an example of silicon dioxide, with the chemical formula SiO2 in nature. It is also known as common quartz. The main ingredient of sand is silica. The most abundant and complex family of materials that includes silica is made up of many mineral compounds and synthesized products. fused-quartz, silica and opal are just a few examples.

It can be used to make structural materials and microelectronics, which are electrical insulators.

What Is Spherical Silica Pulp?

Spherical powder features a flat surface, high specific surface area and strong chemical properties.

First, the powder is very fluid. The resin can be stirred evenly into a thin film. It is easy to add resin, but the quartz powder filling quantity is large. A mass fraction of up to 90% can be achieved. A higher filling quantity of quartz powder will result in a lower thermal conductivity. Additionally, the thermo expansion coefficient of the plastic sealing materials is less. However, monocrystal silica thermal expansion coefficient is closer. These factors can improve the performance of electronic components.

Second, the stress for spherical granules is 60% less than that of angular granules. Furthermore, the stress concentration in plastic seals made with spherical Quartz powder is lower and its strength is higher. The surface of spherical quartz powder has a smooth texture, a small friction coefficient and wear that is low, which means the mold can last for more than a year.

For what purpose is Spherical Silica Powder used?

Mainly used to make electronic packages. Three main components of electronic packaging materials are: substrate, plastic sealing material, lead frame and solder. The advantages of plastic packaging include its simplicity, cost-effectiveness, affordability, and mass production. Plastic packaging currently accounts for over 95% of all integrated circuits worldwide. EMC (epoxy plastic package) is the mainstay of integrated circuit packaging. More than 95% use epoxy plastic seals for their microelectronic components.

The main requirements for integrated circuit packaging are low humidity resistance, low stress and dip resistance. Reflow welding is also an option. Inorganic fillers must be used in epoxy resin. At present, quartz powder is the most common inorganic ingredient. Microelectronics has seen rapid advancement, making large-scale integration circuits more difficult to manufacture. Quartz powder serves as an important support for EMC materials. Not only does it conform to specific requirements of the EMC material, but also meets the high purity and low amount of radioactive elements required, particularly to form the particles according to the spherical specifications.

It is a good-looking powder of silicon, with high purity chemical elements and low levels of radioactive elements. This allows it to be compatible with high-end embedded circuits. The product can significantly reduce the temperature expansion coefficient of plastic sealing materials, lower its dielectric constant, increase stress and greatly improve rigidity.

Apart from being useful in electronic packaging, the spherical Quartz powder can be extensively used in high-grade cosmetics and high-grade precision ceramics. Precision grinding of opto devices and components can also take place.
