Drill Hole Vias at Lisa Bridges blog

Drill Hole Vias. Through hole vias, buried vias, and blind vias. Find out the considerations for aspect ratio, annular ring, signal integrity, and fabrication cost of vias. Where and how to use them. These are referred to as blind vias (from a surface layer to the next layer in) and buried vias (between two internal layers). Learn the difference between blind and buried vias, two types of holes that connect different layers of a printed circuit board (pcb). It is this parameter that is an important determinant of via reliability. When a via is placed in a pcb, the drill size and the depth into the pcb define a via's aspect ratio. There are three main types of pcb vias used: Vias can be used to connect component leads to signal traces or planes or to allow a signal to change signal layers. By drilling vias at certain points during the fabrication process, it was possible to create vias that only spanned two adjacent signal layers. A via is a drilled and plated hole in a pcb that allows a signal to pass from one side of a pcb to the other or to an inner layer. The ability to reliably fabricate vias with different aspect ratios depends on several factors.
