Released by IPC (Association Connecting Electronics Industries), is the comprehensive specification that outlines the requirements for ENEPIG plating on printed circuit boards (PCBs). While earlier standards touched on gold-related finishes, IPC-4556 was specifically developed to provide a reliable framework for ENEPIG, ensuring optimal shelf-life, solderability, and wire bonding capabilities. The Three Layers of ENEPIG (2 to 6 µin)
