Abstract
A technique relates to forming a chip assembly. Top and bottom chip stack elements containing solder pads and a solder material are provided. Soluble standoffs are applied to the bottom chip stack element. The chip stack elements are aligned to bring the top solder pad in proximity to the bottom solder pad and the temperature is raised to a temperature above the melting temperature of the solder material to form a connected chip assembly. The connected chip assembly is cooled to re-solidify the solder material and soluble standoffs are removed from the connected chip assembly.
