Abstract: The package comprises a plurality of metal/polymer laminates whereby electronic components or functional units may be directly attached or plugged into laminated elements to form a unitary package. An element or thermal transposer is included in the package to minimize thermal expansion mismatch between the components and the laminates and conduct thermal energy away from the attached electronic components. The polymer laminates are selected to have a configuration and thermal coefficient of expansion (TCE) that will permit the insertion and locking of materials within the laminates to form the unitary package. A wide variety of components and functional units having different electrical, thermal characteristics may be included in the package. The package is amenable to mass production processes that may be controlled by a designer to obtain packages at a low cost, more flexibility and suitable for complex electronics system.
