Patent ID: 7972905

Claim:
A method of assembling an electronic device, comprising: providing a workpiece having a top surface, and an integrated circuit (IC) die; applying a die attach adhesive precursor between said top surface of said workpiece and said IC die, said die attach adhesive precursor comprising: a plurality of metal particles; a first plurality of first microcapsules having a flowable polymerizable material inside; and a second plurality of second microcapsules having at least one polymerization agent inside effective for inducing polymerization of said flowable polymerizable material to form a first polymer upon rupture of said first and second microcapsules, and applying a force sufficient to rupture at least a portion of said first plurality of first microcapsules and at least a portion of said second plurality of second microcapsules to form a die attach adhesive comprising said first polymer binding said plurality of metal particles, said die attach adhesive securing said IC die to said top surface of said workpiece.
