Why Immersion Gold and Gold Plating are Used on PCB Boards
Introduction Printed Circuit Boards (PCBs) form the backbone of modern electronics, providing the physical platform to mount and interconnect electronic components. Among the various surface finishing techniques applied to PCBs, immersion gold (ENIG – Electroless Nickel Immersion Gold) and gold plating (electrolytic gold) have become two of the most important and widely used processes in…
