US Patent 7262079 Consolidated flip chip BGA assembly process and apparatus

A flip chip packaging technique and associated apparatus that consolidates many or all of the steps in a conventional flip chip packaging process results in substantially decreased packaging time, e.g., only one to two hours, complexity, e.g., requiring fewer pieces and much simpler equipment, and cost, arising from reduced equipment operation and maintenance time and decreased labor. An assembly fixture useful for implementing the consolidated assembly technique engages and holds in place a semiconductor flip chip die with a plurality semiconductor package components in a desired package configuration so that they can be assembled into a semiconductor package with a single application of heat and pressure.
