Hysol GR750 X1 | Black Epoxy Mold Compound

Harmonization Code : 3907.30.00.40 | Epoxy Mold Compounds containing by weight more than 70 % silicon dioxide

Main features

Halogen free
Low CTE: 8 ppm/°C
Amazing adhesion to Nickel (Ni) leadframes

Product Description

Hysol GR750 X1 is a halogen free, black, silica filled (75um cut size) semiconductor grade epoxy molding compound. It has amazing pull tab adhesion on Nickel (194 N) and very low CTE (8 ppm/°C). It's a very all around product that balances High Tg with low CTE and amazing adhesion. The entire GR75XX product line is alterations to the same formulation to the fit everybody's needs and X1 hits a balanced sweet spot. The product is still in active development so some properties might end up higher or lower depending on the state of the final formulation. There is also a Low CTE (6 ppm/°C) lab version lurking around. Contact us if you're interested.

Hysol GR750 X1 is a technologically advanced, non anhydride, green epoxy molding compound with excellent electrical performance, designed for high power devices especially for high temperature application with low moisture absorption requirements. Typical packages can be Silicon Carbide SiC MOSFETS packages in TO 247 and TO 263 among (us) others. Renewable energy, EV battery chargers, High voltage DC/DC converters and Switch Mode Power Supplies are only some of the applications where these packages can be used. GR750 X1 delivers outstanding performance and ease of use. It meets UL 94 V-0 flammability at 1/8 inch thickness.

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.

Flexural Strength
Flexural Strength @ 25°C Flexural Strength @ 25°C Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test. This is the flexural strength tested at Room Temperature, 25°C	136 N/mm2

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.	8 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.	42 ppm/°C

Gel Time Gel Time Gel time is the time it takes for a material to reach such a high viscosity (gel like) that it is no longer workable. It is usually measured for different temperature conditions and even though it does not refer to full cure it is advisable to never move or manipulate the material after it reached its gel time since it can lose its desired end properties.
Gel Time @ 175°C / 347°F	24 s

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.
