In the modern electronic packaging materials industry, silica powder and LTCC glass powder are core raw materials. After being processed to the micron or even nanometer scale through ultrafine grinding, they have found increasingly widespread application in the copper clad laminate (CCL) manufacturing industry due to their excellent properties such as acid and alkali corrosion resistance, high insulation, and high thermal conductivity.
Ultrafine grinding enhances the specific surface area and dispersibility of the raw materials. Combined with the optimization of surface treatment processes, their interfacial compatibility with resin systems has been significantly improved. As fillers, they not only help control the production costs of CCLs but also precisely optimize key properties such as the coefficient of thermal expansion (CTE) and enhance flexural strength, thereby highlighting their functional value.
