  • Patent number: 11266010
    Abstract: A portable electronic device packaged into a System-in-Package assembly is disclosed. The portable electronic device can include a substrate and a plurality of components mounted on the substrate and included in one or more subsystems. Interference between subsystems or from external sources can be reduced or eliminated by disposing an insulating layer over the components, forming narrow trenches between subsystems, and depositing one or more layers of a multi-layer thin film stack on the insulating layer and filling the trenches. In some examples, the multi-layer thin film stack can include an adhesion layer, a shielding layer, a protection layer, and a cosmetic layer. In some examples, the multi-layer thin film stack can include multi-functional layers such as a protection and cosmetic layer.

    Abstract: Electrical components may be packaged using system-in-package configurations or other component packages. Integrated circuit dies and other electrical components may be soldered or otherwise mounted on printed circuits. A layer of encapsulant may be used to encapsulate the integrated circuits. A shielding layer may be formed on the encapsulant layer to shield the integrate circuits. The shielding layer may include a sputtered metal seed layer and an electroplated layer of magnetic material. The electroplated layer may be a magnetic material that has a high permeability such as permalloy or mu metal to provide magnetic shielding for the integrated circuits.
