摘要:
This invention relates to compositions useful as adhesives and more particularly to the preparation of heat-cured epoxy-based adhesive compositions with improved impact resistance and good adhesion to oily metal substrates.
摘要:
The present invention is directed to a photocurable composition for use as an encapsulant, for underfill or attachment adhesives, capable of curing at wavelengths greater than 290 nm. Reaction products of these photocurable compositions have a low level of extractable halide ion, such as less than 100 ppm. In use, the photocurable composition may be applied, for instance, over the wire bonds that electrically connect a semiconductor device to a substrate to maintain a fixed positional relationship and protect the integrity of the electrical connection from vibrational and shock disturbances, as well as from interference from environmental contaminants.
