I thought the RoHS compliant stuff that Elecraft is doing was all in the ENIG process. I've ordered a K1 and a K3 since RoHS and all the boards are ENIG. Perhaps for the W1 they are using IMAg?
I should explain: ENIG = Electroless Nickel Immersion Gold (or gold pads) or IMAg = Immersion Silver (or silver (whiteish) pads) For the record both have their pluses and minuses such as the IMAg is more susceptibile to oxidization and other cleaning issues (cleaning when the boards are made) where as ENIG is usually less often plagued by cleaning issues however contamination in the process can lead to whats referred to as black pads. ENIG costs a little more and is generally accepted as slightly "better". Probably mostly because of the higher cost. ;) ~BTH On Sat, 2009-07-25 at 19:52 -0400, Don Wilhelm wrote: > David, > > I believe that is one version of the RoHS compliant solder pads. > > 73, > Don W3FPR > > David Heinsohn wrote: > > I just started working on the W1.
