Interesting coat comparisons, I suspect the low Pd costs will hold only till auto production resumes, as that is the driver (ho ho) for Platinum, Palladium and Rhodium pricing. At the same/similar time for similar economic reasons people will presumably stop buying and holding gold. But if I really knew about this sort of stuff I would not be reading TechNet.

Using palladium after nickel and before gold, limits the gold deposition to normally about two microinches as opposed to about four microinches in normal ENIG. If you look at metal pricing, palladium is currently selling for about $230 per oz and gold is selling for about $920 per oz. The ENEPIG process averages about 5 microinches of palladium. By the self limiting nature of the palladium with the gold you are saving around 2 microinches of gold (at $920 per oz) and replacing it with 5 microinches of palladium (at $230 per oz) the cost difference is very small, in fact I have talked to some manufactures using this process and they have stated the process cost less. I believe the perception of the high cost is from the late 90's early 2000 when palladium went as high as $1300 per oz. ENEPIG was gaining popularity in the late 90's when the price of palladium went through the roof. Because of the huge impact of the palladium, it effectively killed this process. In recent years with the cost of palladium stabilizing back down to reasonable levels, we are seeing increased interest in this process. With cost no longer a factor and the enormous benefits using palladium between the nickel and gold layer, I expect you are going to see significant growth in this process.

Hillman Sent: Thursday, April 23, 2009 10:41 PM To: [log in to unmask] Subject: Re: [TN] Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG) Hi Lee - ENEPIG is a very good finish - look up the 1996 SMI conference proceedings where Rockwell published a paper on the topic. One of the big drawbacks of the finish is its cost. There are a couple of good reference books that talk about ENEPIG. When I get back off business travel, I can send your the exact references.
