Abstract:
A method of coupling substrates, comprising the steps of:providing a first substrate having a conductive element formed on a portion of the first substrate; providing a second substrate having a conductive bump formed thereon; disposing a conductive paste on at least a portion of the conductive element, wherein the conductive paste is at least partially uncured; disposing a nonconductive laminate on a portion of the first substrate, wherein the nonconductive laminate is comprised of an epoxy, a curing agent and a toughener comprised of a cyclohexanedicarboxylate and is at least partially uncured; coupling the second substrate and the first substrate so that the conductive pump is electrically coupled to the conductive element and the second substrate is physically coupled to the nonconductive laminate; and curing the conductive paste and the nonconductive laminate after the step of coupling the second substrate and the first substrate.
