    Abstract: A circuit board includes a large scale logic device and at least one outrigger device wherein signals having a transmission delay budget that exceed a threshold value are produced to the outrigger device for coupling to circuit devices of the circuit board that are external to the large scale logic device. One embodiment of the invention comprises a plurality of outrigger devices that communicate with the large scale logic device by way of parallel data buses, as well as multi-gigabit transceiver data lines. Logic within the outrigger devices is generally limited to signal routing and transmission logic. The large scale logic device further comprises logic to transmit and receive signals to and from the outrigger devices in a way that is transparent to internal logic of the large scale logic device.

    Abstract: An electrical connector assembly (1) includes an LGA connector (2) having a metal clip (25) and a pick up cap (3). The pick up cap has a planar body (30) forming a plane top surface (300). Several holes (302, 303, 309) are defined in the planar body. When the pick up cap is engagingly mounted onto a top portion of the connector, the holes are in communication with a window (258) of the clip. A vacuum suction device can engage the top surface of the pick up cap to move the connector assembly to a desired location on a PCB. When curing adhesive film at high temperature, heated air can flow through the holes to a bottom portion of the connector. Reliable electrical connection between the contacts of the connector and the metal contact pads of the PCB is subsequently produced in a wave solder machine or drag soldering equipment.
