Methods and apparatus for package on package devices with reduced strain
Methods and apparatus for package on package structures. A structure includes a first integrated circuit package including at least one integrated circuit device mounted on a first substrate, a plurality of package on package connectors extending from a bottom surface and arranged in a pattern of one or more rows proximal to an outer periphery of the first substrate; and a second integrated circuit package including at least another integrated circuit device mounted on a second substrate and a plurality of lands on an upper surface coupled to the plurality of package on package connectors, and a plurality of external connectors extending from a bottom surface of the second substrate; wherein the pattern of the external connectors is staggered from the pattern of the package on package connectors so that the package on package connectors are not in vertical alignment with the external connectors. Methods for forming structures are disclosed.
