Patent ID: 7197818

Claim:
A method for implementing customizable dielectric printed circuit card traces comprising the steps of: providing an outer layer of a printed circuit card including a plurality of signal traces; electroplating selected signal traces to provide a selectively increased trace height; said selectively increased by electroplating traces surrounding a plurality of said signal traces; selectively removing dielectric material from the outer layer to define a void near selected signal traces of said plurality of surrounded signal traces filling said void with a selected dielectric material having a selected property; said dielectric material being selected to alter at least one predefined electrical property of the selected signal traces; providing a mating circuit card layer including a plurality of matching signal traces; and attaching said mating circuit card layer to said outer layer by soldering together selected matching traces of said mating circuit card layer and said selectively increased by electroplating traces of said outer layer to create a cavity near selected signal traces.
