ABSTRACT:
A structure and method are disclosed for making high density circuit board. Using photosensitive or other dielectric materials over a circuitized power core, vias and lands are opened up, filled with joining metal and aligned with the next level, eliminating a major registration problem in building up a high density composite and reducing the number of steps in the manufacturing process.
