Abstract

Exemplary embodiments of the invention include a method and apparatus for assembling a semiconductor device. The method may include heating the semiconductor device, which comprises a printed circuit card and a packaging laminate, according to a device heating profile to melt solder material located between an array of contact points on the printed circuit card and an array of corresponding contact points on the packaging laminate; and cooling the semiconductor device to solidify the solder material, wherein during at least a portion of the cooling a temperature of the printed circuit card is kept at substantially a same temperature or a higher temperature than a temperature of an electronic module attached to the packaging laminate opposite the corresponding array of contact points.
