Patent number: 8395256Abstract: Microwave or millimeter wave system packaging having a system with a baseplate, transition board and cover. The baseplate includes microwave or millimeter wave components attached thereto. The transition board includes a first connector attached to a first side thereof and operatively connected to the components, and a second connector attached to a second side thereof and operatively connected to the components through the board. The cover and baseplate form a cavity containing the board and components, and the second connector may be operatively connected to a third connector such as a printed circuit board disposed outside of the cavity and on a higher level assembly. The transition board may further include a fourth connector operatively connected to the components for providing a signal to an external component or device or receiving a signal from an external component or device.Type: GrantFiled: February 2, 2007Date of Patent: March 12, 2013Assignee: Harris Stratex Networks Operating CorporationInventors: Ronald D.

Patent number: 6629365Abstract: A method of providing environmental protection to an electronic component includes placing an electromagnetic shield having at least one cavity in contact with a circuit board having electrical components thereon so as to substantially enclose at least a first compartment between the circuit board and the shield, the shield includes at least one entry hole connecting to the first compartment. A conformal coating is applied by introducing the conformal coating into the first compartment through the entry hole while holding the shield in contact with the circuit board so that the coating is applied to the exposed portions of the circuit board within the compartment, but not applied to portions of the circuit board contacted by the shield. An electrically conductive gasket may be positioned between and in contact with both the circuit board and the shield before the applying of the conformal coating.Type: GrantFiled: February 7, 2001Date of Patent: October 7, 2003Assignee: Ericsson Inc.Inventors: Quentin Scott Denzene, Edwin John Nealis

Patent number: 6301123Abstract: A card module includes a circuit board with a front panel secured along one edge, and a board extractor catch mounted to the front panel. The front panel includes a keyhole. The board extractor catch mounts in the keyhole so that the board extractor catch completely covers the keyhole to prevent air flow through the keyhole. The outer end of the board extractor catch includes a tool-receiving opening to engage a board extracting tool.Type: GrantFiled: March 31, 1999Date of Patent: October 9, 2001Assignee: Ericsson INCInventors: Edwin John Nealis, Quentin Scott Denzene

RF emissions shield including resilient fingers and connector assembly and method including the same
Patent number: 6264480Abstract: 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.Type: GrantFiled: June 16, 1999Date of Patent: July 24, 2001Assignee: Ericsson Inc.Inventors: Edwin John Nealis, Quentin Scott Denzene -
Publication number: 20010004316Abstract: 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. The circuit board may include ground traces that divide the circuit board into sections. An optional electrically conductive gasket may be used between the ground traces and the shield to provide good electrical contact between the shield and the circuit board. 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.Type: ApplicationFiled: February 7, 2001Publication date: June 21, 2001Inventors: Quentin Scott Denzene, Edwin John Nealis
