Ah yes, I did mean I still use the leaded stuff, maybe I should stop chewing it.
?
And at least in Australian, you can buy it easily enough and it’s $10/roll cheaper than lead-free, so yay for us I guess.
?
As far as RoHS, Wikipedia has a reasonable write-up: .? Huh, there’s 10 things on the list now.
?
Weighing by individual materials eliminates cheating.? Say your cable is a metre long, weighs 1000 grams and the solder joints have 2 grams of lead, at 0.2% it’s double the limit.? No problems, just make the cable twice as long.? You still have the same amount of leaded solder but now 2 grams of lead in a 2000 gram cable is 0.1%, so it passes!? Everyone happy!
?
Under RoHs both cables have 40% lead in the solder, so you need to sort that out.
?
They don’t make the limit 0% because easier said than done, plus a tiny little bit of lead in steel & brass makes it easier to machine.
I think you meant to type, "leaded" instead of, "lead free" - your 2nd link is to classic 60-40 Sn-Pb solder. Some of the early Pb free solders were genuinely unpleasant to work with, enough so that whoever did the plumbing in my house chose to silver braze everything instead of using whatever Pb free soft solder was available locally.
