Abstract:
The invention concerns a method for producing an electrical component (10) consisting of a plurality of circuits (16, 18, 20, 22; 40, 42, 44, 46) printed on a corresponding plurality of flat insulating substrates (12, 14; 30, 32; 34, 36) stacked on one another to form a multilayered monolithic wafer, the printed circuits being mutually connected. The substrates are separated from one another by an insulating material (24), and each of the printed circuits having at least one zone for connection (50, 52, 54, 56, 58, 60) to at least another printed circuit, the connecting zones of two circuits to be mutually electrically connected being substantially in straight line with each other for being bored by a hole (70) for the passage of an electric conductor. The holes (70) are bored over the whole thickness of the wafer after the substrates have been stacked.

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).
