If your fabricator understands and controls their in-house ENIG, you should be OK. It seems that fabs don't undererstand ENIG processes well enough to duplicate hyper-corroded nickel, but those that have not seen the defect usually never see it.

Hi 1. Does anyone know what the pros and cons are of ENIG vs Electroplating ? 2. Is there a likelyhood that in either of these processes the gold can flake off after a period of time ? Thanks in advance Milas

So true :) But I think we will have the final fight with the supplier when we will have troubles with the ENIG. We will assembly the product. From my experience, i never found a product with no black pad defects. It depends of the fabrication lots. T

Nicoleta, We're a CM and have produced many millions of solder joints with ENIG boards with no failure attributed to this surface finish. This represents several boards houses. Another poster is correct that any supplier you choose should have a c

I have no experience with soldering to a flash gold finish. We have specified ENIG for a prototype PCB order and the supplier is asking us if they can use flash gold. They are telling us that the two are interchangable which I don't believe. The

Hi Nicoleta, As a board shop, either are good choices but in my experience with my customers ENIG has alway been the favorite due to it is easier to work with in regards to not having to tweak your equipment. As long as the board shop that you are u

Flash gold is just thin gold plating over electroless nickel or electrolytic nickel. Flash gold is electrolytic gold where the panel is connected to a plating rectifier and current causes the plating process to occur. Gold thickness is controlled b

Hi Milas, Here is a link to an artical on the subject. http://pcdandf.com/cms/content/view/4784/95/ The big difference in the to is that ENIG is self limiting where as electroplating is not. All product manufactured with either finish goes throug
