    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. Integrated circuits may be mounted on one or both sides of the printed circuit. A temporary carrier and sealant may be used to hold the encapsulated integrated circuits during electroplating.
