PCB Via: Essential Guide to Vertical Interconnect Access in Circuit Boards
Printed Circuit Board Vertical Interconnect Access (PCB VIAs) are small plated holes that create electrical connections between different circuit board layers. This article delves into the various types, functions, and best practices of PCB VIAs to help you optimize your PCB design. Introduction A via, short for Vertical Interconnect Access, is an essential component of a printed circuit board (PCB) that creates electrical connections between different PCB layers. This small copper-plated hole is drilled or laser-cut through the PCB laminates, intersecting two or more adjoining layers. Comprising a barrel, a pad, and an anti-pad, the via facilitates the flow of electrical and thermal currents across the board. Vias are crucial […]
