Immersion gold is mostly used to call this ENIG (Electroless Nickle Immersion Gold) surface treatment method. The advantage is that nickel and gold can be attached to the copper skin without the use of an electroplating process, and its surface is flatter than electroplated gold. This is especially important for increasingly shrinking electronic parts and components that require flatness. Because PCB ENIG uses a chemical replacement method to produce the effect of the surface gold layer, the maximum thickness of the gold layer cannot reach the same thickness as electroplated gold, and the more the bot...
