Abstract
A method of making a laminated substrate by forming a registration mark on a core layer of the substrate. Then, forming a first layer on the core layer using the registration mark as a fiducial registration point. The first layer is laser drilled through to expose the registration mark on the core layer. A second layer is then formed on the first layer using the registration mark as a fiducial point.
