    Abstract: A microelectronic assembly (10), such as a smart card, is formed by attaching a component subassembly (34) to a substrate (12). The substrate (12) includes a face (26) and defines a via (28) having a via opening (30) at the face (26). The substrate (12) further defines a component cavity (32) at the face (26) that is spaced apart from the via (28). An electrical element (14), such as a wound antenna, is disposed within the substrate (12) and includes a terminal (24) at the via (28). The component subassembly (34) is formed by mounting an integrated circuit component (16) onto a metallic lead (18). The integrated circuit component (16) is electrically connected to the metallic lead (18) by a wire lead (36). A protuberance (20) is connected to the metallic lead (18), preferably by forming a loop from a wire bond. A polymeric body (56) is formed about the component (16) and wire leads (36). The component subassembly (34) is superposed onto the substrate (12), and the component (16) is received in the component cavity (32). The metallic lead (18) is affixed to the face (26) and overlies the via opening (30). The protuberance (20) extends into the via (28) and contacts a conductive body (22) within the via (28). The conductive body (22) electrically connects the protuberance (20) and the terminal (24).

    Abstract: A microelectronic package (10) is formed by placing a lead frame (22) onto an adhesive polyimide tape (38). The lead frame (22) includes a plurality of metallic leads (16) and an opening. An integrated circuit die (12) is positioned onto the molding support (38) within the opening such that a non-active face (32) of the integrated circuit die (12) rests against the molding support (38). Wire leads (18) connect an active face (28) of the integrated circuit die (12) to the metallic leads (16). A plurality of metallic bumps (20) are attached to the metallic leads (16), and a polymeric precursor is dispensed. The precursor embeds the active face (28) of the integrated circuit die (12), the inner surface (19) of the metallic leads (16), the wire leads (18), and the metallic bumps (20). The microelectronic package (10) is then heated to cure the polymeric precursor to form a polymeric body (14). The microelectronic package (10) is then capable of being tested and subsequently attached to a printed circuit board (40) to form a low-profile microelectronic assembly (11).

    Abstract: A surface mount package particularly suitable for transformers and other components having numerous windings of fragile, difficult to handle wire has a housing which includes openings along the lower edge, the housing being plated with an electrically conductive material on portions of the lower edge and in areas surrounding the opening. A component is held within the housing, and the leads of the component are disposed in the openings at a point above the lower edge of the housing, and the leads are electrically connected to the plating surrounding the openings and the plating at the flat portions of the lower edge. The plating on the flat portions of the lower edge can be at any suitable location, i.e., remote from or adjacent to the openings. Additional components can be stacked on the exterior of the housing, as connected to the plating surrounding the openings. Also, the walls and/or the top of the housing can be plated to provide for versatility in connecting the housed component, or any other components, on and around the housing. The plating on the housing may be connected to the plating surrounding the openings and the plating at the flat portions of the lower edge, or may entirely independent of the housed electronic component.
