WebbFirst of all, the process is filling the via hole with a conductive or non-conductive material, and then plating the via on the surface, which provide a smooth flat for solderable surface; There are used in via in pad designs where it can mount the component over the via, or extend the solder joint to the via connection. 2. WebbFill the via with non-conductive material. Conductive material can be used but it’s not recommended since conductive material expands much more quickly than the surrounding laminate when heated which can cause cracks and pad failures during the assembly process. The surface of the plugged via is then plated over with copper.
