Abstract: Apparatus and methods for coating a substrate. In an exemplary embodiment, the apparatus are used to create a metallized substrate for use as an EMI/RFI shield. The apparatus typically includes a movable processing apparatus that is movable orthogonal to the substrate to treat the substrate. The processing apparatus can include a surface preparation assembly, a heating assembly, a thermoforming assembly, a metallizing assembly, a cutting assembly, or the like.

Abstract: The present invention provides electromagnetic interference filters and gaskets. In exemplary embodiments, the filters and gaskets are made from conductively coated reticulated foam having a pore density varying from 10 to 40 pores per inch (PPI). The filters can be used to cover ventilation openings in an electronics enclosure to shield electrical components, equipment and devices from EMI, electrostatic discharge (ESD) and radio frequency interference (RFI) while still providing adequate airflow to enter and cool the system. The filter material may also help prevent dust and dirt from entering the enclosure. The filters of the present invention are also well suited to conductively bridge gaps between mating features of electronic enclosures. The reticulated foam to fabricate the filters allow for excellent compression (generally 20%-50% of the original thickness) under low compressive forces, while easily recovering from the compressive load without noticeable compression set (permanent deflection).

Abstract: The present invention provides in-line equipment and methods for manufacturing an EMI/RFI shield that is integrated formed in a formable sheet. The EMI/RFI shield may comprise a shaped thermoform shell that has one or more conductive layers applied to one or more surfaces. The EMI/RFI shield may be integrally formed with the formable sheet via attachment tabs that are positioned along one or more edges of the EMI/RFI shield.

Abstract: The present invention provides printed circuit boards, EMI shields, and methods that provide an EMI absorbing material and an EMI reflecting material. In one embodiment, the EMI shield comprises a shield body and an EMI absorbing material coupled to the shield body.

Abstract: The present invention provides shielded printed circuit boards and electronic devices. The printed circuit board may comprise an internal network of grounded conductive elements that are coupleable to an EMI shield that is mounted on the printed circuit board. The network of grounded conductive elements are coupleable to a grounded layer and to the EMI shield and provides improved EMI shielding through the volume of the printed circuit board below an electronic component mounted on the printed circuit board.

Abstract: Multi-layered molds and methods for manufacturing multi-layered molds. A metallized layer can be deposited on at least one side of a substrate. The substrate can be shaped and then the metal layer can be deposited onto the shaped substrate. Optionally, an injection molded resin can be deposited onto the substrate and/or metal layer.

Abstract: The present invention provides methods and devices for shielding an electronic component package. In one embodiment, an EMI shield is integrally formed within the package adjacent the die and grounded. The EMI shield may be a metallized shaped polymer layer and may be disposed fully within the package or it may extend out of the package.
