Abstract: An integrated circuit packages comprises a printed circuit board, a non-metal connector, and a metal casing. The printed circuit board includes a ground ring around the non-metal connector. The metal casing substantially encloses the printed circuit board, and has an opening that allows access to the non-metal connector.

Abstract: An electronic assembly includes one or more conductive clamps (302, 304, FIG. 3), which are used to supply current to an integrated circuit (IC) package (308). The conductive clamps are attached to a printed circuit (PC) board (312), which supplies the current to the IC package over one clamp, and receives returned current from the IC package over another clamp. Each clamp contacts a contact pad (330) on the surface of the PC board, and contacts another contact pad (334) on the top surface of the IC package. Vias (338, 339) and conductive planes (340, 342) within the package then carry current to and from an IC (e.g., IC 306) connected to the package. In another embodiment, the clamp (904, FIG. 9) holds a conductive structure (902) in place between the PC board contact pad (908) and the IC package contact pad (914), and current is carried primarily over the conductive structure, rather than over the clamp.

Abstract: The switch has a passive section and an active section or tray that may be docked to the passive section. The passive section contains only the physical interfaces to the switch's external data and telephony networks and power input. It is not intended to be a field replaceable unit and is therefore intended to be mounted in a rack system with all of the power and communications cables attached thereto. The telephony and data ports are routed from the passive section to the active section via connectors on the two sections as well as to a redundancy connector on the passive section that may be physically connected by a cable to a slave unit in a redundant application. The active section or tray contains all of the active components of the switch and is inserted via guides into the passive section. The tray is considered a field replaceable unit and can be inserted into and extracted from the passive section while the system is powered up and operational.

Abstract: An electrical circuit pack ejector system provides a preemptive warning to the circuit pack that allows redirection and disabling of circuit pack functionality prior to ejection and subsequent disconnection of power and input/output signal contacts. The ejector system is based on proximity detection that measures the distance between a Hall-effect sensor and a magnet affixed to an ejector arm. The magnetic field strength increases as the magnet approaches the sensor. Once the sensor threshold is reached, a logical bit from the sensor is flipped and a positive ejector engagement is surmised. As the ejector arm rotates away from the sensor, the magnetic field strength around the sensor is reduced. Once the sensor threshold is reached, a logical bit from the sensor is flipped and a negative ejector engagement is surmised. The circuit pack then redirects and disables functions prior to the power and signal connectors physical disengagement.
