Thermosetting Encapsulants for electronics packaging

摘要

An electronic package is provided where in a semiconductor device on a substrate is encapsulated with a thermally reworkable encapsulant composition including: (a) a thermally reworkable crosslinked resin produced by reacting at least one dienophile having a functionality greater than one and at least one 2,5-dialkyl substituted furan-containing polymer, and (b) at least one filler present from about 25 to about 75 percent by weight based upon the amount of components (a) and (b). Such a process provides a readily reworkable electronic package.
