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

One of our customer wants to change the process from OSP boards to ENIG. His question was: what is the failure rate for ENIG in the last 3 years? well...what to say? I was suggesting a ImAg instead of ENIG. But..nope. Any ideea about this topic? For

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.

Do you have experience with wear resistance of spring contacts on ENIG vs Flash Au? regards, Huub.

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
