Fortuantely, we (in the UK) are sitll allowed to
use leaded solder for
prototypes/home contruction, and for repairs on things that were
originally soldered with leaded solder. But not for devices osld
commerically (except for a few specific uses). So you can sell a kit
and the builder can solder it with lead/tin solder with no problems.
But if you sell the PCB pre-built, you have to use lead-free. Oh
well..
I'm getting used to lead-free solder repairs. The latest was the
PCB in a coffee maker--most people would simply have thrown it into
the trash.
All of the relay PCBs in my Volvo have been reworked using leaded
solder after I started to see odd failures in the electrical system.
I see... A lot cheaper than the official repair of replacing the PCB (in
my expeirence car electronic modules are a form of legalised robbery!),
and doubtless much more reliable.
You'd think that with the massive electronics recycling industry we
have, it'd be simply to simply recycle the (leaded) solder as well.
I don't believe that's got much to do with it!. I am, alas, of the
opinion that manufacturers want to make stuff that fails and can't be
repaired after a rerasoanbel time (a few years) in the hope that you'll
buy a new device. And if they can arrange this in a way that seems
'green' then so much the better.
A major source of lead pollution was the frit seal on
TV CRTs--but
who buys a CRT television nowadays? The problem took care of itself.
Well, I would if I could. I'd buy adelta-gun CRT-bnased TV if I could. I
don;'t mind having to set up the convergence in the position it is to be
used.
Actually, given the choice I'd not have a TV at all. I cna think of
little worth watching...
