Abstract:
A method of producing an array of interconnecting contacts for an integrated circuit package and connecting the array of interconnecting contacts to the package, the method comprising the steps of:a) providing an integrated circuit package having a plurality of contact pads to which an array of interconnecting contacts is to be attached;b) providing three molds, the three molds being configured such that, when the molds are stacked adjacent to one another, the molds form an overall mold which defines a desired shape and relative position for a plurality of interconnecting contacts which make up the array of interconnecting contacts;c) molding the array of interconnecting contacts by filling a first and a third mold with a low temperature contact forming material and filling a second mold with a high temperature contact forming material;d) positioning the three molds containing the molded array of interconnecting contacts adjacent to the integrated circuit package in order from the first mold to the third mold such that each interconnecting contact is positioned adjacent to a corresponding contact pad of the integrated circuit package; ande) attaching the molded interconnecting contacts to their corresponding contact pads of the integrated circuit package.
