Lead free solder issue -tin whiskers

I assume by mere fact the process applies to anything being currently made will have a level of both problems. In my last link it was noted that when switched over from old to new, problem arose as the learning curve was encountered. As you stated, it does happen and i haven't come across so many weird problems for the sake of me. I don't fall back to resoldering because of the close contacts may actually solder more than the problem area with a typical soldering iron. I use a stiff brush now and alcohol to straighten so-called whiskers or electronic wipe towelettes. It seems to help and far easier than resoldering. But that's me and my old eyes... -----Willy

And it was all about this area if you can find the right articles.

And now about technology. http://www.youtube.com/watch?v=C9I_xhaDyxs

Pb is nothing I'll let near such systems.

to the inside, only minimal contact with water is made. Unless the water has reactive contaminants, no lead salts will be produced. It's my guess that the potentially worst practice was using the cold water pipe as an earth ground for one's home. If he plumbing carried much current, there can be damage to the solder joints. I think the jury is still out on PVC and glues used. We tend to find out about the ill effects of some things many decades later.

i saw on "Dirty Jobs" DVD the process where they cleaned a micro-brewery and distillery. They braze, union or flare connect all those fittings. BTW, the custom you're allowed to drink on the job as a benefit but over time, you wean yourself from over-indulgence. ------Willy

Due to the weather we had a broken copper pipe. I had to play with far longer than normal. I "pre-tin" the connections or sweats and rag wipe it down to remove excess. Then flux the heck out of it. It works and believe me you don't want any water near-by because of its own removal but this cold metal takes forever to heat anyways. My aching back is testament to the labor I had to do in awkward place. -----Willy
