ABSTRACT:
This is directed to methods and apparatus for shielding a circuitry region of an electronic device from interference (e.g., EMI). A conductive dam may be formed about a periphery of the circuitry region. A non-conductive or electrically insulating fill may then be applied to the circuitry region within the dam. Next, a conductive cover may be applied above the fill. The cover may be electrically coupled to the dam. The dam may include two or more layers of conductive material stacked on top of one another. In some embodiments, the conductive cover may be pad printed or screen printed above the fill. In other embodiments, the conductive cover may be a conductive tablet that is melted above the fill.
