I'm trying to design a costing matrix for raw cards so our designers can estimate the costs of their raw card designs, this will hopefully slow down their lust for technology and get them considering project budget costs. Does anyone know of where I can access this information so I know a basic cost / sq. inch and then add percentage costs for extra layers, different surface finishes, impedance control, extra drilled holes and if I use buried via's. Any information will be gratefully received.
