What does silica powder mean?
Silica powder is composed of quartz ore and fused silicona. Raw materials are processed through multiple processes, 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 for 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 washing machines. The spherical silica powder, which is among the many epoxy plastic molding materials, has outstanding characteristics, including high fluidity, low stress and a small surface area. Spherical silica powder has a higher filling rate than angular, which is able to reduce the copper clad laminates as well as epoxy plastic mold compounds. Most commonly, the coefficient of linear extension is used for high-end copper laminations like aerospace and 5G communication, as well as epoxy plastic packaging materials to large-scale integrated circuit packaging.
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 an ingredient in copper clad laminating, has many advantages, including 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 (a curing agent), and silicon powder as filler. This material can be used to encapsulate chips in electronic devices. Filling rates account for between 60-90% in epoxy molding compound composition.
