摘要： An electrically continuous, grounded conformal EMI protective shield and methods for applying same directly to the surfaces of a printed circuit board. The EMI shield adheres and conforms to the surface of the components and printed wiring board. The shield takes the shape of the covered surfaces while adding little to the dimensions of the surfaces. The EMI shield includes low viscosity, high adherence conductive and dielectric coatings each of which can be applied in one or more layers using conventional spray techniques. The conductive coating prevents substantially all electromagnetic emissions generated by the shielded components from emanating beyond the conformal coating. The dielectric coating is initially applied to selected locations of the printed circuit board so as to be interposed between the conductive coating and the printed circuit board, preventing the conductive coating from electrically contacting selected components and printed wiring board regions.

摘要： An electrostatic precipitator that removes zinc whiskers from cooling air provided to cool components in an electronics enclosure. The electrostatic precipitator comprises an ionizer configured to apply a charge to zinc whiskers suspended in the cooling air. The electrostatic precipitator also comprises a collector that collects charged zinc whiskers from the contaminated cooling air to generate uncontaminated cooling air for cooling the components of the electronics enclosure. The electrostatic precipitator is configured to be disposed in the cooling air flow path upstream of the components such that the cooling air travels through the electrostatic precipitator prior to impinging on the components.

摘要： An EMI containment assembly for an integrated circuit chip. A frame forms an eletrically conductive wall around the perimeter of the integrated circuit chip. The bottom of the frame makes an electrically conductive contact with a ground trace on the printed circuit board to which the chip is mounted. The top of the frame makes an electrically conductive contact with an electrically conductive heat removal assembly that is disposed over the top of the chip. An electrically conductive bolster plate is mounted on the side of the printed circuit board opposite the integrated circuit chip and is disposed beneath the chip. Because each component of the assembly is electrically conductive, the assembly creates an EMI cage around the integrated circuit chip. Because the frame does not cover the top of the chip, it does not interfere with a thermally conductive contact that is made between the top of the chip package and the heat removal assembly. The assembly of the invention not only provides containment of EMI generated by the integrated circuit chip in a light-weight and cost-effective manner, but it also enables the heat removal assembly to function as effectively as if no EMI containment mechanism were present.
