IPC-4556 establishes that ensure the ENEPIG finish meets its intended functions. The standard's core requirements focus on specific deposit thicknesses, which are critical for preventing corrosion and ensuring reliable joints.

IPC-4556: The Definitive Guide to ENEPIG Surface Finish Specification ipc-4556 pdf

Surface finishes serve two primary roles: protecting the copper circuitry from oxidation and providing a solderable surface for component assembly. IPC-4556 was established to provide clear requirements for ENEPIG, offering a more robust alternative to Electroless Nickel/Immersion Gold (ENIG) by adding a palladium layer that protects the nickel from hyper-corrosion. IPC-4556 establishes that ensure the ENEPIG finish meets
