Get a couple of quotes on ENIG. You may be surprised at the price. HASL, (which is often considered to be the cheapest finish), is now more expensive for us than ENIG due to the extra processes involved.

Hi Ted, look at this tread: Lead-free solder alloy: SN100C from AIM solder then see note of Bob Gilbert (from FCT Assembly) you can have from him very interesting documentation CD about HASL made by SN100C alloy Regards GS

If you are using fine lines and tight spacing ENIG may be cheaper than HASL. This is because there is not as much bridging at the board house between traces so they do less touch up. This would probably be even more true with no-lead. We have been us

Mat, Are you sure you should be using SnPb HASL boards if you are doing prep for lead free? If you aren't actually going to comply with RoHS then fire away. Nearly all of our assemblies are now ENIG and as any re-design comes up on a HASL board it is

Has anyone had issues with chips not making a reliable connection in sockets with a matte tin finish (RoHS compatible)? We have had issues with these types of sockets. I sent some to the manufacturer, and was told there weren't any problems. We re
