I can't help but generally agree...
To 'me' Solder means 'lead'. I mean, we are talking about tiny amounts compared to the Massive amounts of 'Lead'
used in numerous other types of industry. Does it really matter!!!
So much MASSIVE reduction in the use of Lead these days, far out weighs the use of 'solder' at Home on a Cct Board..
P.S. A few 'fun-facts'...
The term 'Plumber', meant a Lead Worker, from the word 'Plumb' meaning 'Lead'. And a 'Plumb-Bob' was a 'Lead' weight
hung from a string, in order to check the vertical accuracy, 90 deg from a 'Level'. Not much Lead work now, but glueing
PVC pipes!!
