  • Patent number: 10477684
    Abstract: Techniques and mechanisms for facilitating connection between a packaged device and a substrate of another device. In an embodiment, a device—such as a printed circuit board—comprises a substrate and a hardware interface at a first side of the substrate, the hardware interface to couple the device to a package including integrated circuitry. The device is further configured to couple to a bridge device via contacts disposed at a second side of the substrate. An interconnect extends from the hardware interface to one of the contacts at the second side. In another embodiment, coupling the substrate to the bridge device interconnects two of the contacts at the second side to one another via the bridge device, where one or more contacts of the hardware interface (e.g., only a subset of all such contacts) are also interconnected with the bridge device via the second side.
