Abstract
A method for producing a panel of a multi-layer electronic circuit package and resulting article of manufacture is provided comprising the steps of coating a circuitized core material that has been cut into panels with a dielectric material and copper cover sheets; forming circuits from the cover sheets by etching; applying an adhesive polymer across the dielectric material covering the entire area of the panel; applying a cover sheet; drilling the panel to form through-holes and vias; seeding and plating the through-holes and vias with joining metal; applying photo-resist to the panels exposed with an image of the area of the panel to be joined and developed; and etching the cover sheet and the photo-resist away in the area of the panel to be joined to expose the adhesive polymer.
