CIRCUIT MODULE AND METHOD OF PRODUCING THE SAME

摘要

A circuit module includes a wiring substrate having a mount surface, a conductor pattern, and an insulating protective layer, the mount surface having first and second areas, the conductor pattern being formed along a boundary between the first and second areas on the mount surface, the insulating protective layer being formed on the mount surface, the insulating protective layer covering the mount surface and the conductor pattern; a plurality of electronic components mounted on the first and second areas; an insulating sealing layer having a trench, the insulating sealing layer covering the plurality of electronic components, the trench having a depth such that the trench penetrates the protective layer to reach a surface of the conductive pattern; and a conductive shield having first and second shield portions, the first shield portion covering an outer surface of the sealing layer, the second shield portion being electrically connected to the conductor pattern.
