What is spherical Quartz Powder?
Spherical Quartz Powder, also known by spherical Silica Powder, is an amorphous powder of quartz that has particles of spherical shape and contains silicon dioxide as its main component.
Spherical quartz is used primarily for copper clad laminations and epoxy mold compound fillers in large scale integrated circuit packaging. However, it also has applications across high-tech areas such as aerospace and fine chemicals.
Why is Quartz Powder Spheroidized
1. The surface area of the ball has the lowest value, isotropy is high, film is well mixed with resin, resin is added in small amounts, fluidity is best, filling powder can be as high as 90%, and mass ratios can reach up to 90.5%. The increase in silica micropowder filling rates.
The filling rate for silicon micropowder is higher, but the plastic sealing compound’s thermal expansion coefficient is lower. This means that the thermal conductivity of the plastic sealing material is less than monocrystalline silicon’s, and produces better electronic components.
2. The strength and stress concentration of the plastic sealing compound made from spherical dust is the lowest. The plastic sealing compound made of angular powder has a stress concentration equal to 1, but the stress from the spherical is only 0.6. When the spherical dust plastic sealing compound is used to encapsulate the integrated circuit chips, the yield is High. This makes it difficult to cause mechanical damage during transportation, installation and use.
3. Spherical powder’s friction coefficient is low, so the mold wear is very minimal. The mold also has a long service-life. The service life of the mold is doubled when compared to angular powder. The cost of plastic sealing compound packaging molds is high. It is therefore necessary for some to be imported.
4. Silicon micropowder has the ability to strengthen epoxy resin. Spherical powder can also enhance this effect.
