Hello Hey Wood! I have to say Bismuth is a no-no for late night snacking. Although it is low in calories and tastes even better with sprinkles on top, the dang Canadians dissagree! http://www.eurekalert.org/pub_releases/2004-11/uot-sob111504.php

H.W. At a lead-free seminar I took last year, the PhD lecturer, who is known to be a huge proponent of Bismuth, said the same thing. It is absolutely non-toxic and is used in foods, makeup, etc.

Russ, I believe the concern over solders with bismuth in them was that if you did happen to get a little Pb in your solder joint, you could create an alloy that could melt at around 100 degrees C, and that's not all that warm. At least, that's what

Hi Samir, Bismuth seminar! Good ol' Jenny. Yes, you should see me there! No karaoke this year, OK? You singing rap tunes is just so..... WRONG!

If you can't find bismuth wire, use 42Sn58Bi. For more, look here: http://www.mrs.org/s_mrs/bin.asp?CID=2274&DID=48689&DOC=FILE.PDF

What is your alloy composition? Although your solder paste may have lower melting point, what about the alloy / metal used for plating solder lands on PCB and component termination? In most cases, there is no reliable joint as such solder may not com

We currenty process SnBi. I have not ever seen silver added though. What kind of issues are you having?

Hi, I didnt use currently . . . but seriously looking to make use of SnBi or SnBiAg. I would like to know any limitations/reliability study on this process . . . moreover need some guidance/help to adopt this alloy in process Regards Vijai

The only problem with non silver tin bismuth is its very prone to shock damage and components fall off,literally. Would only recommend it with Silver additions and around 1%.

This is the dilema during this transition period. Here is a tip: If you see typcial solder joints on a lead free process, but only on one component type....it probably has a significant quantity of lead in it (ex. Sn90/Pb10...and so on) If using T
