Manufacturing computer systems with fine line circuitized substrates

Circuit boards are manufactured by forming a substrate with a dielectric surface and laminating a metal foil onto the substrate. The metal foil is patterned to form a first wiring layer. A permanent photoimagable dielectric layer is formed over the wiring layer and via holes are formed through the d...
