ABSTRACT:
An improved circuit board structure and method of forming the same are provided. The circuit board includes an insulating core and has plated through holes connecting the circuitry on both sides and intermediate layers of the core. A permanent dielectric material is applied on at least one surface of the board covering the circuitry and plated through holes. Vias are formed through the dielectric material and signal lines are formed on the top of the dielectric material connected to the circuitry onto the board through the vias. Additional layers of dielectric material with additional wiring and vias can also be formed for multi-level wiring.
