  • Patent number: 11355427
    Abstract: Techniques and mechanisms to facilitate connectivity between circuit components via a substrate. In an embodiment, a microelectronic device includes a substrate, wherein a recess region extends from the first side of the substrate and only partially toward a second side of the substrate. First input/output (IO) contacts of a first hardware interface are disposed in the recess region. The first IO contacts are variously coupled to each to a respective metallization layer of the substrate, wherein the recess region extends though one or more other metallization layers of the substrate. In another embodiment, the microelectronic device further comprises second IO contacts of a second hardware interface, the second IO contacts to couple the microelectronic device to a printed circuit board.

  • Publication number: 20060192280
    Abstract: A method of forming polymer reinforced solder-bumped containing device or substrate is described. The method comprises the following steps: providing a device or substrate having at least one solder bump formed thereon; coating a predetermined portion of the device or substrate with a curable polymer reinforcement material forming a layer on the device or substrate, partially curing the curable polymer reinforcement material to provide a solder-bumped structure comprising a partially cured polymer reinforcement material, and, making a connection between the solder-bumped structure formed and a printed circuit board or array of attachment pads and fully curing the partially cured polymer reinforcement material to provide a reinforced interconnection. Full curing of the polymer reinforcement material may take place either during the “reflow step” or subsequent to it (post-curing).
