Unfortunately, since the demise of Borders bookshops over here, I can no
longer get Circuit Cellar Ink off the shelf. And I didn't find enough of
interest in each issue to feel it was worth subscribing to. So I have not
had a chance to see this editorial.

I've heard it said that tthe extra energy required to heat the solder
bath to the highter temperature needed for lead-free solder does more
environmetal damage than leaded solder would.
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..
Of course like most classiccmpers, I intend to minimiue the environmetal
impact of my lead/tin solder by keeping the things I have made/repaired
out of the landfill for many, many, years.
