This is through the solid copper (un-etched) outer layers and feature etched internal layers (for a 4+ layer board). Copper burrs are removed in the deburring … In integrated circuit (IC) design, a via is a small opening in an insulating oxide layer that allows a conductive connection between different layers. A via on an integrated circuit that passes completely through a silicon wafer or die is called a through-chip via or through-silicon via (TSV). Through-glass vias (TGV) have been studied by Corning Glass for semiconductor packaging, due to the reduced electrical loss of glass versus silicon packaging. A via connecting the lowest laye…
