Application of white corundum micro powder in electronic industry
(1) Packaging materials
In the packaging process of electronic components, white corundum powder is widely used as packaging material. Because white corundum micropowder has high hardness, high wear resistance and good chemical stability, it can effectively protect components from erosion by the external environment. In addition, it can help to improve the heat dissipation effect of components and extend their service life.
(2) Abrasives and polishing materials
The high hardness and uniform particle size distribution of white corundum powder make it an ideal abrasive and polishing material.
In the manufacturing process of electronic products,
White corundum micro powder is suitable for grinding, polishing and polishing processes of various materials, such as precision processing of silicon wafers, sapphire, glass and other materials.In addition, white corundum powder also plays an important role in the production of high-end LCD displays and optical lenses.
(3) Circuit board manufacturing
White corundum powder also plays a role in the manufacturing process of circuit boards. During the manufacturing process,
white corundum powder have the high hardness and high wear resistance，so it can improve the surface flatness and roughness control accuracy of the circuit board, thereby improving the conductive performance and reliability of the circuit board. In addition, white corundum powder can also be used as filler and other additives to manufacture circuit board substrates with high thermal conductivity and high insulation properties.
