This is one reason why we changed package styles. Maybe consider getting a different size tube, say from 500g to 1000g or something like that. We use jars for lead paste, and tubes for lead free (different application method) If lead free comes off t

I am Just starting to explore the Pb free soldering processes. It sounds like you have been involved for some time. I have a million questions, do you have contact info that I could use to discuss off line? Thanks

Our preference has been ENIG. We find that we achieve higher quality (visually) soldering for through hole and surface mount parts, with less handling issues than when we use white-tin, or immersion tin. We are about to do a test on some boards tha

Lead free solder is bad for the environment, while increasing product costs. The US looked at restricting lead use a few years ago, took no action, and has no plans to enact frivolous legislation like the "greens" have foisted upon the Eurolanders a

on sections ive looked at with 7 microns of silver and 4microns of copper, the silver had been totally absorbed into the solder in most places and a large amount in some places all the copper as well, so i think the answer is that to provide long ter

Silver on your copper or brass part is a solderability protection. The silver diffuses into the solder and you solder to the base metal, either the copper or brass in your case. Soldering to copper is well known. The issues are soldering to brass

What are the long term issues with high tin content solders on parts plated with silver over copper? Is it possible that the silver will be absorbed by the solder then over a long period of time the tin will react with the copper causing it to part

We bought a new lead free wave from Electrovert about a year ago and opted to not have the nitrogen options installed on this machine. We could not justify the cost of the nitrogen used versus the benefits that we would see. One downfall is that you

We are changing /adding a lead free wave. This will either be a conversion of a leaded wave or a new purchase. Nitrogen seems to be a necessity in selective soldering lead free, should I presume the same for a wave process? I am interested in first h

You will need to preheat the boards for a lead free selective solder process. A preheat module is critical for any wave or selective solder process, if you don't get the board preheated properly the solder is going to resist flowing to the top of the
