Product Description

Hysol GR910-LB is a high-performance, epoxy-based encapsulant meticulously engineered to meet the stringent requirements of Ball Grid Array (BGA) Thin Factor (TF) card applications. With electronics trending toward smaller and thinner designs, GR910-LB delivers the durability and protective performance needed to ensure long-term reliability in ultra-compact packages.

Its advanced formulation offers robust thermal and mechanical properties, protecting delicate interconnects and microstructures from environmental stress, thermal cycling, and mechanical strain. Whether used in consumer electronics, telecommunications, or high-density computing modules, Hysol GR910-LB provides critical reinforcement and peace of mind.

Product Key Features:

  • Superior Moisture Resistance: GR910-LB shields sensitive semiconductor components from moisture ingress, a critical factor in maintaining the integrity and functionality of small form-factor devices operating in diverse environments.
  • Excellent Flowability and Fill: This molding compound ensures complete and void-free encapsulation of intricate BGA packages, even with tight pin pitches and complex geometries. This leads to enhanced mechanical strength and improved heat dissipation.
  • Low Stress and Warpage: GR910-LB minimizes stress on the delicate silicon die and substrate during the molding and curing process, significantly reducing the risk of warpage and ensuring reliable electrical connections.
  • Halogen-Free Formulation: Environmentally conscious and compliant with industry regulations, our molding compound is halogen-free, contributing to sustainable manufacturing practices.
  • Exceptional Electrical Insulation: Provides robust electrical insulation, preventing short circuits and ensuring the stable operation of the BGA TF card.

Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Thermal Properties
Glass Transition Temperature (Tg)
Glass Transition Temperature (Tg)
The glass transition temperature for organic adhesives is a temperature region where the polymers change from glassy and brittle to soft and rubbery. Increasing the temperature further continues the softening process as the viscosity drops too. Temperatures between the glass transition temperature and below the decomposition point of the adhesive are the best region for bonding.

The glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs.
145 °C
Thermal Conductivity
Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance.

Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.
