WebENIG plating is much softer than hard gold plating. 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 is also better for the joining ... WebJan 15, 2024 · 1u" of gold for 10cm*10cm costs $0.2, and most Chinese fabs require additional charge for gold coverage >=30%, so the actual cost of gold for a 10cm*10cm board with maximum free coverage would be $0.06. JLCPCB quotes $1496 for 2000pcs of 10cm*10cm 2L 1.6mm FR4 w/ ENIG, and $1104 w/o ENIG. That's $0.20 per board …

An ENIG PCBs have only nickel gold on the pads, which conforms well within the copper layer and doesn't creep outside it.
WebENIG (electroless nickel immersion gold) is a two-layer metallic surface finish that consists of a very thin layer of gold plated over a layer of nickel. Using an electroless chemical reaction, a nickel layer is first plated on copper pads. An immersion method is then used to apply gold on top of the nickel layer to cover the pads and traces.
