A flexible dielectric layer 42 overlaps a first face of the micro electronic device having an interval therebetween. A periphery 86 of the flexible dielectric layer 42 extends beyond a periphery of the micro electronic device. The micro electronic component package has a plurality of conductive posts 40a-40f exposed on a surface of the flexible dielectric layer, and mutually connected to the micro electronic device electrically. One of the plurality conductive posts is arranged on the periphery of the flexible dielectric layer. A soft layer 74 is arranged between the first face of the micro electronic device and the flexible dielectric layer. The soft layer overlaps at least one of the conductive posts arranged on the periphery of the flexible dielectric layer. The package comprises a support body 84 in contact with the micro electronic device and the soft layer. The support body overlaps the periphery of the flexible dielectric layer.
Abstract:
A microelectronic package includes a microelectronic element (80) having faces and contacts (83) and a flexible substrate (90) spaced from and overlying a first face (84) of the microelectronic element (82). The package (80) also includes a plurality of conductive posts (98) extending from the flexible substrate (90) and projecting away from the first face (84) of the microelectronic element (82), wherein at least some of the conductive posts (98) are electrically interconnected with the microelectronic element (82), and a plurality of support elements (88) supporting the flexible substrate (90) over the microelectronic element (82). The conductive posts (98) are offset from the support elements (82) to facilitate flexure of the substrate (90) and movement of the posts (98) relative to the microelectronic element (82).
Abstract:
A microelectronic interconnect element can include a plurality of first metal lines (110) and plurality of second metal lines (110') interleaved with the first metal lines (110). Each of the first and second metal lines has a surface (122), (120') extending within the same reference plane. The first metal lines (110) have surfaces (120) above the reference plane and remote therefrom and the second metal lines (110') have surfaces (122') below the reference plane and remote therefrom. A dielectric layer (114A) can separate a metal line of the first metal lines from an adjacent metal line of the second metal lines.

Abstract:
A radio frequency chip package is formed by assembling a connecting element such as a circuit board (52) or flexible circuit tape having chips (72, 84) thereon with a bottom plane element (20) such as a lead frame incorporating a large thermally-conductive plate (22) and leads (40, 42) projecting upwardly from the plane of the plate. The assembly step places the rear surfaces (78) of the chips (72) on the bottom side of the connecting element (52) into proximity with the thermal conductor (22) and joins the conductive traces (60) on the connecting element with the leads. The resulting assembly is encapsulated, leaving terminals at the bottom ends (45) of the leads exposed. The encapsulated assembly may be surface-mounted to a circuit board (102). The leads (40, 42) provide robust electrical connections between the connecting element (52) and the circuit board (102).
