Die Encapsulants


Primary uses of Dow Corning® and Dow Corning Toray Silicone® encapsulants are to seal, protect, and preserve electrical characteristics of integrated circuit packages. This a dispensable underfill effectively relieving stress caused by the CTE (coefficient of thermal expansion) mismatch between the silicon die and the substrate.  These products have been successfully demonstrated with typical dispensing or liquid injection molding equipment.
