This is a question for Jens Schönfeld:
A few years back, regulations took effect that reduce or in some cases ban lead use for PCBs. For which products that you have made is this the case?
The reason I ask is because of the phenomenon of micro-fissures in solder joints with low lead content.
If you are wary of answering this, I should tell you this is just a heads-up question for the future, right now I enjoy my ACA630 which works fine and probably will for years
It's just an information gathering question intended for many years from now, and not really a concern at all at this point. I'd love it if you could share some thoughts on the subject.
