The Main application Fields of Spherical Quartz Powder

(The Main application Fields of Spherical Quartz Powder)

What is spherical quartz powder?

Spherical quartz powder has the advantages of smooth surface, large specific
surface area, high hardness and stable chemical properties. First of all, the
spherical powder has good fluidity, and is evenly stirred with the resin to form
a film. The higher the filling amount of quartz powder, the lower the thermal
conductivity, the smaller the thermal expansion coefficient of the molding
compound, and the closer to the thermal expansion coefficient of single crystal
silicon, the better the performance of the electronic components produced.
Secondly, the stress of spherical powder is only 60% of the stress of angular
powder, and the molding compound made of spherical quartz powder has the
smallest stress concentration and the highest strength. Finally, the spherical
powder surface is smooth, the friction coefficient is small, and the wear on the
mold is small, which can prolong the service life of the mold by more than 1
times.

Application fields of spherical quartz powder

The application field of spherical quartz powder is very wide, and its use as
electronic packaging material is the largest market in its application field.
Electronic packaging is the supporting industry of integrated circuits. With the
development of large-scale and ultra-large-scale integrated circuits, integrated
circuits are becoming more and more refined, and the requirements for packaging
materials are getting higher and higher, and the packaging forms are
continuously optimized and updated. The three main materials of electronic
packaging are substrate material, plastic packaging material, lead frame and
solder. Because of its low cost, simple process and suitable for mass
production, plastic packaging has developed rapidly since its birth, and its
share in packaging has become larger and larger. Currently, plastic packaging
accounts for 95% of the integrated circuit market worldwide. %above. Among
plastic encapsulants, epoxy encapsulant (EMC) is the mainstream of integrated
circuit packaging at home and abroad, and more than 95% of microelectronic
components are encapsulated by epoxy.

In microelectronic packaging, high moisture resistance, low stress, low alpha
ray, resistance to dip soldering and reflow soldering, and good plastic sealing
performance are mainly required after the integrated circuit is packaged. In
response to this, the epoxy molding compound must be doped with inorganic
fillers in the resin matrix. The inorganic fillers currently used are almost all
quartz micropowder (silica micropowder). With the rapid development of the
microelectronics industry, large-scale and ultra-large-scale integrated circuits
have higher and higher requirements for packaging materials. As an important
support material for EMC, quartz powder not only requires its particle size to
meet the specific range of packaging, but also requires its purity High and low
content of radioactive elements, especially for particle shape, put forward
spheroidization requirements.

Spherical silicon micropowder not only has good shape, but also has high
chemical purity and low content of radioactive elements, which can meet various
technical requirements of high-end integrated circuits. The rigidity, wear
resistance, weather resistance, impact resistance, compressive resistance,
tensile resistance, moisture resistance and flame resistance of the
earth-enhanced products make the products have good arc resistance insulation
properties and UV radiation resistance, etc., and have become electronic
packaging. Indispensable key material. In addition to being mainly used in the
field of electronic packaging, spherical quartz powder can also be widely used
in the manufacture of electronic inks, optical fibers, high-grade cosmetics,
advanced precision ceramics, precision grinding of optical devices and
electronic components, and as fillers for special paint coatings, etc.
