Abstract
A microelectronic assembly including a dielectric region, a plurality of electrically conductive elements, an encapsulant, and a microelectronic element are provided. The encapsulant may have a coefficient of thermal expansion (CTE) no greater than twice a CTE associated with at least one of the dielectric region or the microelectronic element.
