Review: IPC-4556 (PDF) – Specification for Electroless Nickel/Immersion Gold (ENIG) for Printed Boards
IPC-4556
In the high-stakes world of printed circuit board (PCB) manufacturing, surface finish is not merely an aesthetic choice—it is a critical determinant of solderability, reliability, and shelf life. Among the many standards governing these finishes, stands out as the definitive specification for Electroless Nickel / Immersion Gold (ENIG) .
ENEPIG (Electroless Nickel/Electroless Palladium/Immersion Gold)
In the rapidly evolving world of electronics manufacturing, reliability is the bedrock of success. As components become smaller and circuit boards more complex, the industry has turned to as a multi-functional surface finish. Central to the success of this technology is the IPC-4556 Specification , the definitive guide for implementing this tertiary layered finish. What is IPC-4556? ipc4556 pdf
This standard bridges the gap between standard circuit boards and thick-film technology, allowing designers to combine logic-level control circuits with high-power current carriers on a single substrate. Buy it: IPC Store (~$80–150 USD for members/non-members)
