Using Vias to Improve PCB Density

Vias are very small, yet they are an important part of a circuit board, as they interconnect layers of a multi-layer printed circuit board (PCB). Nothing, not even a component lead, will ever enter a via hole for soldering, which is what differentiates them from a plated through hole (PTH). Moreover, it is not necessary for a via to extend from one side of the board to the other, although they can do so as a through via. Since those momentous beginnings, Advanced Assembly has never strayed from this focus, assembling the most complex boards for some of the largest and most innovative tech companies in the world, including many Fortune 500 organizations.
