Silica is a form of silicon oxide. Its chemical formula is SiO2, and it is the most common type of quartz found in nature. Silica is the major component of sand. Silica, which can be formed as a variety of mineral compounds or synthetic products, is one of the most complex materials. fused-quartz, vaporsilica, silica and aerogel are just a few examples.
It is used as a structural material, in microelectronics and in components of the food and pharmaceutical industries.
What is Spherical Silica Pulp?
Spherical quartz dust has many advantages including a smooth surface and large specific surface area. It also has stable chemical properties.
First, the resin is evenly mixed into a thin film. The resin addition volume is low and the quartz powder filling is large. The mass fraction can exceed 90.5%. The lower the quartz powder filling, the smaller the thermal conductivity and the higher the thermoplastic coefficient of the plastic sealing materials, the better the electronic components that are produced.
Second, the stress in spherical powder can be 60% lower than that of angul powder. Furthermore, the stress concentration in a plastic seal made from spherical Quartz powder is the lowest, while the strength is highest. The surface of spherical dust is smooth, the friction coefficient and wear are small, and the mold’s life span can be extended to more than one-hundred years.
What is Spherical Silica Powder Used For?
Used mainly as electronic package materials. Substrate material, plastic sealing material, and lead frame/solder are the main materials used in electronic packaging. Plastic packaging has seen rapid development since its birth. The current global market for integrated circuits is 95% because of its simplicity, cost effectiveness, and mass production. EMC (epoxy plastic packaging) is the mainstay of integrated circuit packaging. More than 95% use epoxy plastic sealing.
The main requirements for integrated circuit packaging are low stress, low moisture, low alpha radiation, dip resistance, reflow weldability, and low humidity. Inorganic fillers must be used in epoxy resin. At present, quartz powder is the most common inorganic ingredient. Microelectronics industry is rapidly developing, and large-scale, very big-scale integrated circuits are more difficult to manufacture. Quartz powder, which is important support for EMC materials, not only conforms to encapsulate specific scope but also meets the requirements of high purity, low-content radioactive elements, in particular the particle shape using the spherical requirements.
Spherical silica powder has a great shape and can be used to meet the technical requirements of high end integrated circuits. It can significantly reduce the thermal extension coefficient of plastic sealing material, reduce it’s dielectric constant and reduce stress. Also, it can increase the rigidity. Tensile resistance, compression resistance, weather resistance. Fire resistance.
Spherical quartz can be used for electronic packaging. It can also used extensively in the production of high-grade optical ink, high-grade precision clays, precision grinding optical devices and electronic parts, as well as filler in special paint coats.
