    摘要: A method of forming polymer reinforced solder-bumped containing device or substrate is described. The method comprises the following steps: providing a device or substrate having at least one solder bump formed thereon; coating a predetermined portion of the device or substrate with a curable polymer reinforcement material forming a layer on the device or substrate, partially curing the curable polymer reinforcement material to provide a solder-bumped structure comprising a partially cured polymer reinforcement material, and, making a connection between the solder-bumped structure formed and a printed circuit board or array of attachment pads and fully curing the partially cured polymer reinforcement material to provide a reinforced interconnection. Full curing of the polymer reinforcement material may take place either during the “reflow step” or subsequent to it (post-curing).

    摘要: An underfill composition with enhanced adhesion and improved resistance to cracking comprising an epoxy resin in combination with a difunctional siloxane anhydride epoxy hardener and optional reagents. In some embodiments, the epoxy resin includes a functionalized colloidal silica filler having a particle size ranging from about 1 nm to about 500 nm. The difunctional siloxane anhydride epoxy hardener can optionally be combined with liquid anhydride epoxy hardeners. Cure catalysts, hydroxyl-containing monomers, adhesion promoters, flame retardants and defoaming agents may also be added to the composition. Further embodiments of the present disclosure include packaged solid state devices comprising the underfill compositions.
