Abstract: Application of a thermally and/or electrically conductive compound to fill a thermal and/or EMI shielding gap between a first and a second surface. A supply of a fluent, form-stable compound is provided as an admixture of a cured polymer gel component, and a particulate filler component. An amount of the compound is dispensed from a nozzle, screen, stencil, or other orifice under an applied pressure onto one of the surfaces which, when opposed, form the gap, or into the gap formed between the surfaces. The gap is at least partially filled by at least a portion of the dispensed compound.

Abstract: The present invention discloses methods, materials and devices for facilitating electromagnetic/radiofrequency interference (EMI/RFI) shielding and thermal management in packaging circuits. More specifically, a method of packaging integrated circuits with improved thermal and EMI management, a process of treating a compound for use as a thermal interface and/or an EMI shield, and an EMI shielding and thermal management apparatus. More specifically, the present invention divulges methods and apparatuses for adjusting viscosity of a thermally and/or electrically conductive (or thermally conductive and/or electrically insulative), form-in-place, fully cured compound thereby rendering the compound dispensable. Further, a process of treating a compound for use as a thermal interface or/and an EMI shield is disclosed. The compound is an admixture of a particulate filler component and a pre-cured gel component.

An exothermic reaction of the reactive foil is initiated, which provides a molten foil available for joining of two objects.
