Abstract
Vias may be established in printed circuit boards or similar structures and filled with a monolithic metal body to promote heat transfer. Metal nanoparticle paste compositions, such as copper nanoparticle paste compositions, may provide a ready avenue for filling the vias and consolidating the metal nanoparticles under mild conditions to form each monolithic metal body. The monolithic metal body within each via can be placed in thermal contact with one or more heat sinks to promote heat transfer. Adherence of the monolithic metal bodies within the vias may be promoted by a coating upon the walls of the vias. A tin coating, for example, may be particularly suitable for promoting adherence of a monolithic metal body comprising copper.
