Via

Meaning in electrical & electronics engineering, with examples

nounCommon term

In electrical & electronics engineering, via means: A small plated hole in a PCB that connects a trace or copper area on one layer to another layer.

In Turkish: via, geçiş deliği, katmanlar arası geçiş

How it is used

Used in multilayer PCB design. Engineers place or add vias, talk about via size and drill size, and distinguish through-hole vias from blind and buried vias. Groups of vias under hot components carry heat to other layers and are called thermal vias.

Example sentences

  1. Put a via next to each decoupling capacitor to reach the ground plane.

  2. Blind vias would make the board much more expensive.

Common collocations

  • through-hole via
  • blind via
  • thermal via
  • via size
  • add a via
  • PCBShort for printed circuit board: a flat board of insulating material with copper tracks that hold electronic components and connect them to each other.
  • traceA copper line on a PCB that carries current or a signal between pads, working like a flat wire. British engineers often call it a track.
  • ground planeA large, continuous area of copper on a PCB layer that is connected to ground. It gives signals a short, low-impedance return path and helps reduce noise.
  • footprintThe pattern of copper pads, holes and markings on a PCB that matches a component's package, so that the part can be placed and soldered correctly.
