LINQSOL EMC-7142 | Black Epoxy Mold Compound
- Green epoxy molding compound
- Designed for SOP and QFP
- Low water absorption, low stress, and excellent moldability
LINQSOL EMC-7142 is a green epoxy molding compound specifically developed for the encapsulation of small outline packages (SOP) and quad flat packages (QFP). Its high spiral flow at 175 °C satisfying the required standards for SOP and QFP molding. LINQSOL EMC-7142 has low modulus that meets low-stress requirements. Additionally, with a UL 94 V-0 flammability rating and low water absorption, EMC-7142 guarantees strong performance and outstanding reliability. This product is deliberately formulated without the inclusion of substances prohibited by the European Union RoHS and REACH. Previous packages using EMC-7142 met the MSL 1 preconditioning requirements successfully. Overall, LINQSOL EMC-7142 seamlessly integrates advanced material properties, safety compliance, and superior performance to deliver a reliable solution for semiconductor device encapsulation.
| 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.

| 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.
| UL 94 Rating
UL 94 Rating
Flammability rating classification.
It determines how fast a material burns or extinguishes once it is ignited.
HB: slow burning on a horizontal specimen; burning rate less than 76 mm/min for thickness less than 3 mm or burning stops before 100 mm
V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed.
V-1: burning stops within 30 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
V-0: burning stops within 10 seconds on a vertical specimen; drips of particles allowed as long as they are not inflamed.
5VB: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may develop a hole.
5VA: burning stops within 60 seconds on a vertical specimen; no drips allowed; plaque specimens may not develop a hole
Before use, let LINQSOL EMC-7142 reach room temperature for 24 hours. Keep the bag unopened and stored in a dry location with a relative humidity of ≤50% during thawing to prevent moisture contamination.
Use the materials within 72 hours after removing the container from cold storage.
Storage and Handling
LINQSOL EMC-7142 is available in pressed pellets in a wide range of sizes to meet specific customer needs. To ensure product integrity, keep it away from oxidizing materials. For long-term storage, maintain a cold environment. The shelf life when stored below 5 °C is 183 days.
