Abstract: A system for prototyping electrical circuits, as well as creating production circuits, without using solder. Stand-in electrical components 110a are placed on a carrier 100a and scanned 310. From the resulting data, a machine tool or laser ablation system 410 then creates a negative master 420a with aperture(s) 530 into which production components 810 are placed and secured. Component leads 820 or packages are encapsulated with electrically insulating material 910 with vias 1030a exposing the leads. Traces 1040 connect appropriate leads forming a circuit sub-assembly 1000 which can serve as a basis for a circuit assembly formed through a reverse-interconnection process.
