Patent ID: 6971163

Claim:
A thermally curable adhesive composition, comprising: (A) a compound selected from the group consisting of (i) a thermosetting polymer and (ii) a monomer which is polymerizable to yield a thermosetting polymer, wherein the thermosetting polymer (i) and the thermosetting polymer yielded by polymerization of the monomer (ii) are crosslinkable when subject to a chemical crosslinking agent; and (B) a chemical crosslinking agent selected from the group consisting of (i) polyacids, (ii) polyanhydrides, and (iii) hydrazides, wherein the crosslinking agent has fluxing properties, is a solid at ambient temperature and is insoluble in the thermally curable adhesive composition until heated to a soldering temperature; and wherein the composition is thermally curable when heated to the soldering temperatures.
