摘要:
A composition includes: (I) an alkenyl functional, phenyl-containing polyorganosiloxane, an Si—H functional phenyl-containing polyorganosiloxane, or a combination thereof; (II) a hydrogendiorganosiloxy terminated oligodiphenylsiloxane having specific molecular weight, an alkenyl-functional, diorganosiloxy-terminated oligodiphenylsiloxane having specific molecular weight, or a combination thereof; and (III) a hydrosilylation catalyst. A light emitting device is made by applying the composition onto a light source followed by curing. The composition provides a cured material with mechanical properties suited for use as an encapsulant for a light emitting device.
摘要:
A process for fabricating an electronic component includes a liquid injection molding method for overmolding a semiconductor device. The liquid injection molding method includes: i) placing the semiconductor device in an open mold, ii) closing the mold to form a mold cavity, iii) heating the mold cavity, iv) injection molding a curable liquid into the mold cavity to overmold the semiconductor device, v) opening the mold and removing the product of step iv), and optionally vi) post-curing the product of step v). The semiconductor device may have an integrated circuit attached to a substrate through a die attach adhesive.
