ENIG is an answer to major industry trends such as lead-free requirements and rise of complex surface components (especially BGAs and flip chips), which require flat surfaces. But ENIG can be expensive, and at times can result in what is commonly known as “black pad syndrome,” a buildup of phosphorous between the gold and nickel layers that

The ENIG PCB plating process The Electroless Nickel step, standing for the EN in ENIG, is an auto-catalytic process that involves depositing nickel on the palladium-catalyzed copper surface. The reducing agent, containing nickel ions, must be replenished to provide the proper concentration, temperature, and pH levels necessary to create a consistent coating.

Grain sizes are about 60 times larger with ENIG plating, and hardness runs between 20 and 100 HK 25. ENIG plating holds up well at only 35 grams of contact force or less, and ENIG plating typically lasts for fewer cycles than hard plating. ENIG plating boards underdo even coating using nickel and gold to achieve a proper bond.
