So I am curious, what are people thinking about the use of bismuth in lead
free termination finishes. I am not talking about solder containing Bi.
The only supplier I have come across so far specifically mentioning they use
Bi is NEC. They have a doc on their website, called "Japan's best kept
secret" http://www.cel.com/pdf/marcomnews/japan_best.pdf that claims
that SnBi is recommended by JEITA, as opposed to the recommendation of JEDEC
for Matte Sn. They make it sound as if a lot of companies are using this
plating, but I haven't come across any other components so far that use it.
The main concern I have is that I keep getting the impression that the next
metal that the EU will be gunning for eliminating is Bi, so it doesn't sound
like a smart direction to go.
Thoughts?
