WebJun 18, 2024 · The most common type of via is a plated through hole (PTH) which involves drilling a hole through all the layers in a PCB until you exit out the other side. The walls of a PTH are plated with a thin layer of copper that forms a conductive barrel that links all the layers together. There are also non-plated through holes (NPTH) which are used ... WebPCB vias should ideally provide conductive paths, passing electrical signals from one layer to another to integrate each PCB layer they pass. The Use of Non-Plated-Through-Holes in …
WebMay 12, 2015 · 5. Placing a via on or very near to a pad can result in a weak connection or even tombstoning due to the solder being pulled away during reflow. It is recommended to have a small amount of solder mask between the pad and the via in order to prevent this from happening. Share. Cite.
WebJan 14, 2024 · Type I HDI may use PTH vias and blind vias, but no buried vias.
