Abstract: An RF emissions shield for grounding a chassis to an associated connector mounted on a backplane includes a shield body, mounting means for securing the shield body to the backplane, and grounding means for electrically connecting the shield body to the connector. At least one spring member is integral with the shield body and is adapted to engage the chassis such that the spring member is biased against the chassis. Preferably, the at least one spring member includes a plurality of curved, resilient fingers extending from an edge of the shield body. The mounting means may include an aperture defined in the shield body, the aperture sized and configured to receive the connector such that at least an engagement portion of the shield body along the aperture engages the connector.

Abstract: An electromagnetic shield including at least one entry hole is placed in contact with a circuit board, thereby substantially enclosing a compartment. With the shield and circuit board held together, conformal coating is introduced into the compartment through the entry hole. The conformal coating coats the exposed portions of the circuit board within the compartment, but does not coat the portions of the circuit board contacted by the shield. In addition, a connector seal may be used to form a barrier preventing entry of environmental contaminants into critical connector interface areas. The connector seal is inserted into the forwardly facing pin cavity of a male connector so that the male pins pierce through the connector seal. When the female connector is joined to the male connector, the front face of the female connector abuts the connector seal.
