Hysol GR2822 | Low stress Black Epoxy Mold Compound

Main features

For Conductive Polymer Tantalum Solid Capacitors
Ultra-low stress epoxy mold compound
MSL3 260°C - Thin Wall Crack Resistance

Product Description

Hysol GR2822 is a silica filled (88%), black, epoxy molding compound. Despite what the name implies, it is not a newer version of 2820 but an improved version of our gold GR2811. Hysol GR2811 showed poor moisture resistance (crack after MSL3) and discolouration issues under harsh circumstances. GR 2822 was developed to solve those issues and while black, be used for demanding applications.

Hysol GR2822 heat curable EMC, meets JEDEC MSL 3 requirements and is a green product designed for tandalum conductive polymer capacitors. It exhibits very low stress, low moisture absorption and good electrical performance.

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.

Shelf Life Shelf Life Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties. It differs vastly per product and it is based on temperature and storage conditions. The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.

Moisture Absorption

Moisture Absorption
Moisture absorption shows the capacity of a polymer to absorb moisture from its environment.

Absorbed moisture can reduce the glass transition temperature and strength of a polymer and can also result in popcorning, unreliable adhesion or voids in the bond line due to moisture desorption or entrapment.

Moisture absorption should always be mentioned with the test conditions to provide a meaningful frame of reference.

Volume Resistivity

Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.

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.	7 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.	36 ppm/°C

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.
