A method of creating a mathematical model which is employed in the
determination of at least one work location in a multi-layered laminated
circuit panel. The mathematical model for modifying drill data takes into
consideration translational and rotational compensations caused by the
encountered stretching or shrinking of the multi-layered panel subsequent
to pressing or due to thermally processing, whereby the mathematical
model may be utilized to modify drill data in order to accurately predict
hole or via locations.
