Abstract:
A method of fabricating a hybrid printed circuit board on a dielectric substrate, the method comprising the steps of:masking a first pattern on a first side of the dielectric substrate;masking a second side of the dielectric layer;etching said first side of the dielectric layer to form a first conductive pattern while maintaining the integrity of said second side of the dielectric layer;removing the mask from said second side of the dielectric layer and from said first conductive pattern;then 1) masking a second pattern on said second side of the dielectric substrate;2) masking said first side of the dielectric layer;then 3) etching said second side of the dielectric layer to form a second conductive pattern while maintaining the integrity of said first side of the dielectric layer; andremoving the mask from first side of the dielectric layer and from said second conductive pattern.
