What is Silica Powder?

Quartz powder or silica powder is constructed from pure quartz (natural quartz or fused quartz) by squashing, picking, cleansing, acid treatment, high temperature melting, squashing, great grinding, as well as category, along with iron and also various other processes refined to satisfy the needs of the use of powder.

Silica is a sort of silicon oxide, chemical formula is SiO2, in nature is the most common quartz and also different microorganisms. Silica is the primary element of sand. Silica is among the most complex and also plentiful families of products, in the type of a variety of mineral substances and also synthetic products. Significant examples include integrated quartz, vapor silica, silica, opal, and aerogel.

It is utilized in structural materials, microelectronics (as electric insulators), as well as parts in the food and also pharmaceutical industries.

What is Spherical Silica Powder?

Round quartz powder has the advantages of a smooth surface, big details surface, high hardness, and secure chemical residential or commercial properties.

To start with, the spherical powder has good fluidity, and also the material is mixed into a film equally. The resin addition quantity is small, and also the filling amount of quartz powder is high. The mass fraction can rise to 90.5%. The greater the loading quantity of quartz powder, the lower the thermal conductivity, the smaller sized the thermal expansion coefficient of the plastic securing product, and also the closer to the thermal development coefficient of monocrystal silicon, the better the efficiency of the digital parts created.

Secondly, the stress and anxiety of spherical powder is just 60% of that of angular powder, as well as the stress concentration of the plastic seal made from spherical quartz powder is the lowest and the toughness is the greatest. Ultimately, the surface of spherical powder is smooth, the friction coefficient is small, the wear of the mold and mildew is small, and also the service life of the mold can be expanded more than 1 times.

What is Spherical Silica Powder Used For?

Generally utilized as digital packaging materials. The 3 main products of digital packaging are substrate product, plastic sealing product and also lead frame and also solder. Because of its low cost, straightforward procedure, as well as ideal for mass production, plastic packaging has actually been established swiftly given that its birth, accounting for an enhancing share in product packaging, the present plastic packaging on the planet represented greater than 95% of the integrated circuit market. Among the plastic packaging materials, epoxy plastic product packaging (EMC) is the mainstream of integrated circuit packaging, more than 95% of microelectronic elements make use of epoxy plastic securing.

In microelectronic packaging, the major demands of incorporated circuit product packaging high wetness resistance, low anxiety, low alpha ray, dip resistance as well as reflow welding, great sealing performance procedure. Consequently, epoxy resin need to be doped with not natural fillers in the resin matrix, the inorganic fillers utilized at present are almost quartz powder. With the quick growth of microelectronics sector, large-scale, very massive integrated circuit is greater as well as higher to the need of product packaging products, quartz powder, as an essential support of EMC materials not only its dimension satisfy encapsulate certain extent, however likewise the demands of its, high purity, low web content of contaminated components, especially for the bit form utilizing the spherical requirements are put forward.

Round silicon powder not only has good shape, however additionally has high chemical purity and also low content of contaminated components, which can meet the technological requirements of high-end integrated circuits. It can considerably minimize the thermal growth coefficient of plastic sealing product, minimize its dielectric continuous, decrease stress and anxiety, substantially improve the strength, put on resistance, climate resistance, impact resistance, compressive resistance, tensile resistance, wetness resistance, fire resistance, to make sure that the products have good arc insulation resistance and also uv radiation resistance.

In addition to being used in the area of digital packaging, spherical quartz powder can also be commonly made use of in the manufacture of electronic ink, fiber optics, state-of-the-art cosmetics, state-of-the-art precision porcelains, accuracy grinding of optical devices and electronic elements, and also utilized as filler of unique paint layers, and so on.
