    摘要: Systems and methods disclose reduction of conductive paint overspray while maintaining paint thickness uniformity over the perimeter of a cap encapsulating at least one integrated circuit (IC) module on a panel of !C modules. The layer of conductive paint electrically couples with wirebonds on the panel to form at least part of an electromagnetic interference (EMI) or radio frequency interference (RFI) shield that attenuates EMI or RFI during operation of the IC module. Optimizing the spray nozzle diameter, fluid pressure, coaxial air pressure, spray heights, speeds, and spray pattern reduces paint waste and achieves edge uniformity. The reduction in paint overspray reduces paint waste, which in turn, reduces production costs. With the reduced amount of paint needed for coating a panel, the cost per unit can be significantly reduced.

    摘要: 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 overmoid structure formed over the packaging substrate and dimensioned to substantially encapsulate the RF components) and the RF-shielding wirebonds. The overmoid 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 overmoid structure so that the conductive paint layer, the RF-shielding wirebonds, and the ground plane form an RF-shield for the RF components).
