Abstract
Through-holes in a substrate are masked during plating of the substrate by substantially filling the through-holes with a liquid material, followed by applying a photoimageable material to an external surface of the substrate, forming a predetermined pattern in the photoimageable material, circuitizing the predetermined pattern and then removing both the photoimageable material and the liquid material from the through-holes.
