Scott, I can think of multiple directions your process may take you, depending other attributes of the part. Not sure just how much actual brazing you will be doing with one component being tin plated. Maybe you just want a higher temp solder than the normal SnPb or SAC solders. I would certainly work with Indium for preforms and pastes, SPM for precious metal preforms, and Handy & Harmen for pastes and performs. I would be greatly surprised if you had to go anywhere else to get the assistance you required. If your project just required a higher temp solder alloy, like a 300+°C high-lead alloy, that will open you up to a whole slew of other solder mfrs as well. Hope this helps a bit.

I'll be brazing a Sn plated Cu leadframe to a rather thick (0.062") copper bracket which may or may not also be plated. Can anyone point me towards reputable suppliers of brazing materials? Hopefully a supplier with good apps engineering support to help bring me up the learning curve. Google turns up quite a few sources, so I'm hoping to narrow the field some with recommendations from you folks. Scott Post Staff Manufacturing Engineer P.O.U. 0000-001E-0CTC 2151 E.
