We are looking at potentially doing a pcb that is enig finished as called out on its fab. drawing. We plan on a standard 63/37 water soluble paste. Is there any pro's and cons to this process with a pcb plated as such. What is the main advantage that

It stands for Elettroless Nikel Immersion Gold, a kind of PCB finishing Entek (there are several kinds) is a brand name of an OSP (Organic Solderability Preservative)kind of PCB finishing. Regards............GS

We have been using this finish almost exclusively for fine pitch boards for about 5 years. Make SURE you use a board house that does the gold plating in-house. There are some potential issues as DaveF stated. The only problem we have encountered is w

We use ENIG whenever possible, to the extent that we will try to talk customers out of Pb-free HASL until our keyboard punching fingers bleed. It's much more solderable than HASL and it's flat.

They probably the same. Most likely someone is saying immersion gold [immersion Au] as a short hand for ENIG [ Electroless Nickel - Immersion Gold]. It is very uncommon to plate gold directly on copper, because gold and copper form a brittle interm
