What does silica powder mean?
Silica powder is made up of fused silica or natural quartz. As raw materials they undergo multiple processing such as grinding and precision classification. The most popular products are fused silica powder and crystal silicon. The micropowders and the spherical-silica micropowder are examples.
Silica powder has mainly two main applications
Crystalline silica powder can be used to produce copper-clad laminates in refrigerators, air conditioners, or other household appliances. Fused silica is used primarily for copper clad laminations in smartphones, tablet computers and air conditioners. The spherical silica powder, which is one of many epoxy plastic molding materials, has outstanding characteristics, including high flexibility, low stress and a small surface area. Spherical silica powder has a higher filling rate than that of angular, which is able to reduce the copper clad laminates as well as epoxy plastic mold compounds. It is used primarily in high-end copper-clad laminates, such as aerospace, 5G communication, and epoxy plastic packaging material for large-scale integrated Circuit packaging, such as smart phones, wearable devices, and other small-sized products.
Copper Clad Laminate – Application of silica powder
It’s a good idea to add performance fillers to copper clad laminating to enhance the board’s heat resistance and reliability. Silica powder, which is used extensively in the manufacture of copper clad laminating products, has characteristics such as heat resistance and linear expansion coefficient.
Epoxy Molding Compound: Use of silica powder
A molding compound that is composed of epoxy resin (as matrix resin), high-performancephenolic resin as a curing agent and silicon powder as a filler. This material can be used to encapsulate chips in electronic devices. Filling rates account for between 60 and 90% of the epoxy molding compound mixture composition.
