  • Patent number: 11528809
    Abstract: A BGA structure having larger solder balls in high stress regions of the array is disclosed. The larger solder balls have higher solder joint reliability (SJR) and as such may be designated critical to function (CTF), whereby the larger solder balls in high stress regions carry input/output signals between a circuit board and a package mounted thereon. The larger solder balls are accommodated by recessing each ball in the package substrate, the circuit board, or both the package substrate and the circuit board. Additionally, a ball attach method for mounting a plurality of solder balls having different average diameters is disclosed.

  • Publication number: 20220113788
    Abstract: The present disclosure describes programmable logic that may be operated in a turbo processing mode to cause an ongoing operation to be completed faster than a scheduled completion time. With at least some of the remaining time to the scheduled completion time, power savings may be realized by operating the programmable logic into a deep sleep mode, where configuration memory associated with the programmable logic may be set to a suitable voltage level as to not cause data loss at lower or zero voltage levels but otherwise realize power savings relative to an amount of power consumed during average processing operations.
