Abstract:
In one embodiment, the present invention includes a circuit board having integrated contacts to mate with corresponding pads of a semiconductor device. At least some of the integrated contacts are of varying sizes to enable different contact resistances between the corresponding integrated contacts and pads, enabling reduced loading forces to adapt the semiconductor device to the circuit board. Other embodiments are described and claimed.
Abstract:
A two-dimensional adjustable edge connector adaptor to support high bandwidth signal paths. The edge connector adapter includes a housing having a cavity formed in one side and an edge connector extending outward from an opposing side. The edge connector includes contact members that are configured to function as conventional edge connector contacts on one end, while the opposing end includes a leg that is in contact with first side of an elastomer connector disposed in the cavity. The elastomer connector facilitates electrical coupling between each contact member and a corresponding board contact on a board having a connector edge that is inserted into the cavity, wherein each board contact includes a leg that is in contact with a second side of the elastomer connector. The adjustable edge connector adaptor enables the board to be positioned in both the horizontal and vertical directions relative to the edge connector.
Abstract:
A bottom heat dissipating device may be attached to a bottom surface of a printed circuit board (PCB). A top surface of the bottom heat dissipating device may be thermally coupled with a backside surface of one or more electronic components mounted on the bottom surface of the PCB. A top heat dissipating device may be attached to a top surface of the PCB. The top heat dissipating device may be thermally coupled with the bottom heat dissipating device through a thermally conductive coupling member to provide a conductive path for heat transfer from the bottom heat dissipating device to the top heat dissipating device. An opening adjacent to an edge of the thermally conductive coupling member may allow air flow between the top and bottom heat dissipating devices. The PCB may be part of a mezzanine card, such as a Peripheral Component Interconnect (PCI) mezzanine card (PMC).
Abstract:
The present invention relates generally to apparatus and methods for the spreading and dissipation of thermal energy from heat-producing components. More particularly, it relates to a heat transfer apparatus and methods particularly useful in the electrical arts. One embodiment of a heat transfer apparatus include but not limited to, a spring-biased member comprising a first side member, a second side member, and a connecting member adapted for spring-biased removable attachment to a heat-producing device. Another embodiment of a heat transfer apparatus is a spring-biased carrier that attaches to a heat-producing device and which carries a member, such as a finned plate. Another embodiment of a heat transfer apparatus is a spring-biased member comprising fingers for conducting thermal energy to a structure. Another embodiment of a heat transfer apparatus is a spring-biased clip used to attach separate heat-spreading/dissipating members, such as a finned plate, against a heat-producing member.

Abstract:
Rotating latching mechanism for securing Advanced Telecom Computing Architecture (ATCA) mezzanine card (AdvancedMC) modules within mezzanine slots on an ATCA carrier board. The rotating latching mechanism includes a rotating latching member having a handle coupled to a shaft to which a latching paddle and position detector actuator paddle are also coupled. The rotating latching member is pivotally coupled relative to a faceplate of a module proximate to the handle, and the shaft at the opposite end is supported by a rear bearing support member coupled to the modules circuit card. As the handle is rotated, the latching paddle is rotated to engage a cutout formed in a strut coupled to the ATCA carrier board, thus latching the module in place. The position detector actuator paddle is also rotated to cause a position detector to be actuated.
Abstract:
Pressure sensors that are fabricated to sense low pressures are tested and calibrated by providing a controlled gas flow or leak to create a pressure during testing. Rather than placing the pressure sensor in a sealed environment, a controlled leak of a gas is used to induce a stable and controllable pressure region over the pressure sensor during testing. The stable low pressure region is monitored via a sensing tube.
Abstract:
A method according to one embodiment may include providing a heat generating component disposed on a first side of a first circuit board, and transferring heat from the heat generating component through the first circuit board to a second side of the first circuit board. The method according to this embodiment may further include slidingly thermally coupling the second side of the first circuit board to a thermal solution disposed on a second circuit board. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
Abstract:
A thermal management apparatus is provided, wherein heat generated by an electronic component coupled to a backside of a carrier substrate may be transferred to an opposite front side of the carrier substrate through a thermal conductor sized to pass through an opening in the carrier substrate.
