    摘要: The invention provides an apparatus and method for simulating a mold cooling process for injection molding. The mold includes a moldbase and a cavity; the method comprises the steps of creating a plurality of cavity meshes for the cavity, automatically creating a plurality of uniform or adaptive moldbase meshes for the moldbase, and determining the relationship between the cavity meshes and the moldbase meshes. Based on the relationship, a numerical method is applied to calculate the temperature distributions of the cavity and moldbase in the mold cooling process.

    摘要: 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.
