Abstract:
A circuit board includes a dielectric layer and sacrificial bumps on the dielectric layer in predetermined circuit common areas. A conductive seed layer is printed on the dielectric layer and the sacrificial bumps. A conductive circuit layer is plated onto the conductive seed layer. Sections of the conductive circuit layer and the conductive seed layer in the circuit common areas are removed. Optionally, the circuit board may include a metal substrate, with the dielectric layer applied on the metal substrate.
