Through Hole Via Definition
A through-hole via is a hole that runs through the entire PCB, connecting the top and bottom layers. It can be used to achieve internal connections or serve as a mounting hole for components. Because through-hole vias are easier to produce and more cost-effective, they are the most commonly used type of via.
FAQs
A via consists of a barrel, a pad, and an anti-pad. A through-hole via is a copper plated hole that traverses the entire printed circuit board from one top to bottom. It forms a conductive path that connects all the layers. Through-hole vias are the easiest and most cost effective to fabricate.

PTHs and vias are holes used in PCBs for conducting electricity. PTHs pass through the entire board and connect different layers. In contrast, vias are used to connect different parts or components on the same PCB layer.

The term via (or via hole) means an electrical connection between different layers of a printed circuit board. Via is basically a small hole made through the PCB laminates that crosses two or more adjacent layers.
In summary, PTHs and vias both enable vertical conductivity through a PCB, but have distinct differences:Â PTHs span entire multilayer boards while vias only interconnect locally within or between adjacent layers. PTHs connect components across layers whereas vias route traces between layers.
