Abstract:
A method of making an electronic package, said method comprising the steps of:providing a substrate having a substantially planar surface; patterning the surface of the substrate to define a circuit area having a circuit on a first portion of the surface and a bare area of substrate material without a circuit on a second portion of the surface, the bare area being substantially coplanar with the surface of the substrate; applying a first dielectric layer to the first portion of the surface of the substrate defining the circuit area but not to the second portion of the surface of the substrate defining the bare area, thereby creating an anchor opening in the first dielectric layer corresponding to the bare area; positioning an electronic component on the circuit area and electrically coupling the component to the circuit; and applying an encapsulant to the electronic component, to the first dielectric layer, and through the anchor opening to the planar surface of the substrate, but not past the planar surface into the substrate, thereby bonding the encapsulant directly to the surface of the substrate, with the anchor opening spaced inwardly from the perimeter of the encapsulant.
