  • Patent number: 5842273
    Abstract: A method for compliant conductive interconnect whereby conductive adhesive is dispensed directly onto conductive sites of a first substrate and, while adhesive is wet or with partial or complete curing, a second substrate is aligned and placed in contact with adhesive deposits, thereby completing the interconnect. After assembly, un-filled underfill shrinks sufficiently to compress compliant adhesive and external clamping is largely eliminated. The method is scalable as low as about 6 mils with no real upper limit according to the percentage conductive particles by volume in the adhesive.
