why is 63-37 eutectic solder not universally preferred?

Because you can't sell it in the EU if it's got lead in it.


It is illegal to produce boards with lead, just check the internet on
RoHS. It is allowed in military applications and some medical devices
as reliability is lower.

Let's be clear that the United States has less stringent regulations.
AIUI, commercial (as opposed to consumer) boards for sale in the U.S.
may still use leaded solder.

As far as Mark's belated entry into this old thread, I assume he's
trolling.


Hmm.. I didn't realize that there were any regulations on leaded solder here
in the USA. I just thought we got consumer grade crap that was manufactured
for sale in the EU that happens to be ROHS compliant.
