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.

Abstract:
In a state in which a multilayer electronic component including a resin layer disposed on a mounting board side is mounted on a mounting board, even when deformation, such as deflection and strain, occurs, a stress on the multilayer electronic component is relieved by this structure. In a multilayer electronic component (1), ends (12, 13) of columnar conductors (8, 9) protrude from a main surface (14) of a resin layer (6) facing the outside. The multilayer electronic component (1) is mounted on a mounting board (2), and the ends (12, 13) of the columnar conductors (8, 9) are electrically connecting to conductive lands (26). In this case, a predetermined gap (31) is formed between the multilayer electronic component (1) and the mounting board (2).
