Do you still use leaded solder? I was today refused to buy it ...

This is everything from soldering boards with SMT devices to building audio cables.

Seriously, i think those of you railing against lead-free solder are just complaining about "The Gubbmint won't let me do something I want to do waaaah waaaahh complain complain bitch moan."

That, or they were dealing with early alloys that maybe weren’t as good, with equipment not quite up to the task. Then they never looked at it again, even though it’s been tweaked a ton.

Those certainly haven’t proven to be the widespread calamity predicted 20 years ago.

One client asked us if there were any substitute for the lead shielding, and the only ones available were tungsten (quite expensive) and gold (very expensive).
For medical equipment, one vendor sold a lovely tungsten-loaded polymer shielding material that could be injection molded and was safe for human contact, also quite expensive.

It is about lead-containing electronics going to landfills w/o proper recycling. Hopefully X-ray machines are not just dumped but recycled instead, so supposedly no problem with lead in them.

This looks like an interesting alternative to try
Just read quality vary significantly between manufacturers  :-//

I use Nihon Superior for SN100C, and Chipquik for bismuth alloys. I am very happy with both.

It was not that long when it was common for electronics to end in the landfills and just anywhere
Today with dedicated bins for electronics and every shop compulsory to take it back not a big issue and you do not see much thrown away in woods and rivers
Even when recycling is done mostly in third world countries in terrible conditions and poisons the people and environment

Someone here on the forum said STANNOL one is terrible

I think that is a big issue as you do not see a huge difference between brands in SnPb stuff
People might just buy some nasty stuff from even reasonably looking brand  :-//
