I'm surprised the percentage of OSP still being processed.

I have the chart that Inge sent me posted. It's at: http://stevezeva.homestead.com/files/PCB_Finish.jpg Actually, I'm not surprised at all. From my own perspective at my current employer, I can count the number of ENIG boards we build here on one hand... everything else is HASL. I haven't built an OSP finished PCB since I was out in California in 1999, and I've only built one ImAg PCB. At my last employer we built a few more ENIG boards, but the overwhelming percentage was HASL...more like 85-95%. -Steve Gregory- -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Ingemar Hernefjord (KC/EMW) Sent: Tuesday, September 19, 2006 5:32 AM To: [log in to unmask] Subject: Re: [TN] ENIG I've seen all answers on your question. I'm surprised that ENIG has such a low part of the total market, just some 3%, while HASL has more than 60%. See tart statistics which I send to Steve's wall. The statistics is from McMurdy. Inge -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Dan Skweres Sent: den 18 september 2006 23:54 To: [log in to unmask] Subject: [TN] ENIG We have, at times, had an outside plating service have difficulties with plating of ENIG on our bare boards. The interesting anomaly we have encountered is lack of plating on certain pads. They tell us there is something on the surface of the pads but when they return the panels to us we micro etch (copper looks beautiful) and all pads look similar in appearance. We even took a panel and coated immersion white tin with out problems. This tells me that there isn't any thing on the surface of the copper. There is one thing I did leave out. The pads that aren't taking ENIG all happen to be in the same net. Has anyone encountered this? It's almost like there is a charge being created in certain nets not allowing the ion exchange to happen. Could it be entrapped chemistry within vias? Any help and/or direction would be greatly appreciated.
