Disclosed are devices and methods related to a conductive paint layer configured to provide radio-frequency (RF) shielding for a packaged semiconductor module. Such a module can include a packaging substrate, one or more RF components mounted on the packaging substrate, a ground plane disposed within the packaging substrate, and a plurality of RF-shielding wirebonds disposed on the packaging substrate and electrically connected to the ground plane. The module can further include an overmold structure formed over the packaging substrate and dimensioned to substantially encapsulate the RF component(s) and the RF-shielding wirebonds. The overmold structure can define an upper surface that exposes upper portions of the RF-shielding wirebonds. The module can further include a conductive paint layer having silver flakes disposed on the upper surface of the overmold structure so that the conductive paint layer, the RF-shielding wirebonds, and the ground plane form an RF-shield for the RF component(s).

Disclosed are devices and methods related to radio-frequency (RF) shielding of RF modules. In some embodiments, tuned shielding can be achieved by utilizing different structures and/or arrangements of shielding-wirebonds to increase shielding in areas where needed, and to decrease shielding where not needed. Such tuning of shielding requirements can be obtained by measuring RF power levels at different locations of a module having a given design. Such tuned RF shielding configurations can improve the overall effectiveness of shielding, and can also be more cost effective to implement.
