LINQSIL HPS-LT20 | 10-20 µm High Purity Silica

Main features

99.16% high purity silica
Crystalline form
Φ 10-20 µm particle size

Product Description

LINQSIL HPS-LT20 is a high purity silica with a total SiO₂ content of 99.16%. It is commonly used as an EMC filler for semiconductors and can be used in copper claded layers to improve its CTE, thermal resistance and reliability. HPS-LT20 has fewer ionic impurities and low alpha ray emissions while also maintaining a very high purity. Its ultra fine nature makes it ideal for PCB printing inks. It helps with resistance to scratching and wiping, bringing long term reliability to the circuit board.

LINQSIL HPS-LT20 is also applicable in paints and coatings, assisting with the leveling properties, transparency and weather resistance of the materials.

Thermal Properties

Coefficient of Thermal Expansion (CTE) Coefficient of Thermal Expansion (CTE) CTE (Coefficient of thermal expansion) is a material property that is indicative of the extent to which a material expands with a change in temperature. This can be a change in length, area or volume, depending on the material. Knowing the CTE of the layers is helpful in analyzing stresses that might occur when a system consists of an adhesive plus some other solid component.
Coefficient of Thermal Expansion (CTE), α1 Coefficient of Thermal Expansion (CTE), α1 CTE α1 (alpha 1) is the slope of the Coefficient of thermal expansion in a temperature range below the Glass transition temperature (Tg). It explains how much a material will expand until it reaches Tg.	0.0000005 ppm/°C
Coefficient of Thermal Expansion (CTE), α2 Coefficient of Thermal Expansion (CTE), α2 CTE α2 (alpha 2) is the slope of the Coefficient of thermal expansion in a temperature range above the Glass transition temperature (Tg). It explains the extent to which a material will expand after it passes Tg.	0.000001 ppm/°C
