More Information
Summary:Self-assembling microscale electrical and mechanical connections includes a part binding site and a part electrical binding site; and a template binding site comprising a template electrical conductor layer; a metallization layer on the template electrical conductor layer; a bump structure comprising a solder alloy positioned on the metallization layer, wherein the solder alloy is liquefied to allow the bump structure to self-assemble and align with the part electrical binding site using capillary forces, and wherein the solder alloy only liquefies at a temperature above that at which the self-assembly and alignment is performed; and a fluid on the template electrical conductor layer, wherein the fluid comprises a melting point lower than that of the solder alloy, wherein the fluid binds with the part binding site.
