    Abstract: Piezoelectric wafers are affixed to a circuit card to control displacement of the circuit card when vibrated. A trigger wafer located at an anti-node of the dominant mode shape produces a voltage as a function of modal displacement. A control system responsive to the trigger wafer produces voltages that are applied to flex wafers at a different anti-node of the dominant mode shape. The flex wafers expand and contract in a manner that reduces the modal displacement of the circuit card. Multiple flex wafers can exist, affixed to the circuit card substantially opposite each other, or a single flex wafer can exist with a single trigger wafer. The trigger wafer can be located substantially opposite the flex wafer or can be located elsewhere on the circuit card.

    Abstract: An enhanced joint thickness lead used for surface mounting electronic devices to a substrate, wherein a portion of the enhanced joint thickness lead that is substantially parallel to the substance. The enhanced joint thickness lead includes an arcuate structure, which provides an enhanced joint thickness for the solder used to connect the lead to the substrate. The enhanced joint thickness of the solder results in a more robust attachment of the electronic device.

    Abstract: Piezoelectric material is embedded in epoxy layers of circuit cards to control thermal expansion and contraction as a function of temperature changes. A temperature sensor and thermostat generates a controlled voltage as a function of temperature and applies the voltage to piezoelectric blocks within the circuit card. Local areas of the circuit card can have different amounts of piezoelectric material or different thermostats. Piezoelectric blocks can be arranged in regular patterns or can be randomly or pseudo-randomly placed.

    Abstract: A conventional land grid array (LGA) socket assembly uses the same socket contact in the power delivery area and the signal delivery area. Using low current socket contacts in the power delivery area may create self-heating and limit power delivery from a printed circuit board (PCB) to an IC package mounted in the socket. Embodiments of the present invention are directed to an LGA socket assembly that has a separate power delivery contact, which includes contact pins and contacts pads that are ganged using a cross beam to form a comb-shaped contact. In an alternative embodiment of the present invention, an LGA socket assembly has a shorter channel in the power delivery area than in known LGA socket assemblies. In still another embodiment, an LGA socket assembly has a shorter channel in the power delivery area in the signal delivery area.
