Abstract:
An electronic package that includes a composite material base. In one embodiment the electronic package is an expanded wafer-level package. The composite material base is composed of woven strands and polymer material. In one embodiment the composite material base is composed of woven fiberglass strands and an epoxy material. In various embodiments the package includes an electronic circuitry layer on one or another face of the composite material base. In other embodiments conductive vias connect the circuitry layers, including a redistribution layer. In yet another embodiment an electronic package is mounted on the composite material base and electrically couples to the circuit of the expanded wafer-level package. The package having the composite material base is mechanically stronger and can be made thinner than a package that relies on an encapsulant material for structure, and resists cracking.
