CIRCUIT BOARD

摘要

A method of manufacturing a circuit board includes providing a metal substrate and applying a dielectric layer to the metal substrate and sacrificial bumps on the dielectric layer. The method also includes printing a conductive seed layer on the dielectric layer and the sacrificial bumps and plating a conductive circuit layer onto the conductive seed layer. The method includes removing sections of the conductive seed layer and sections of the conductive circuit layer during a circuit common removal process
