    Abstract: The present invention provides an electronic assembly (400) and a method for its manufacture (800), (900, 1000 1200, 1400, 1500, and 1700). The assembly (400) uses no solder. Components (406) or component packages (402, 802, 804, 806) with I/O leads (412) are placed (800) onto a planar substrate (808). The assembly is encapsulated (900) with electrically insulating material (908) with vias (420, 1002) formed or drilled (1000) through the substrate (808) to the components' leads (412). Then the assembly is plated (1200) and the encapsulation and drilling process (1500) repeated to build up desired layers (422, 1502, 1702). The planar substrate (808) may be a flexible substrate (2016) allowing bending of an assembly (2000) to fit into various enclosures.
