Basic solder, basic tools
Basic solder basic tools
I teach soldering , brazing and gas welding to plumbers.
Basic: clean bright and shiny, flux is a must and basic solder.
For electrical parts basic flux core solder. Basic tools.

MULTICORE/LOCTITE MM00975 Solder Wire, 63/37, 0.022" Diameter, 183!aC, 1.102lb: Amazon.com: Industrial & Scientific (thin wire is good)
Wash your hands before you take a leak.

The fact remains that lead free solders just dont work very well regardless of the enviroment considerations
There are much larger sources of pollution that need tackling first

I read somewhere that lead free solder has a tendency to whisker.
Eventually over time close solder joints can short out.
Re:> nigelwright7557.Thats a new one on me. Possibly one more reason NOT to use lead free. Perhaps LARGE scale manufacturers can get away with lead free,But not us small people.BTW what about GaAs thats Arsenic init ???very nasty.
Whisker (metallurgy - Wikipedia)
It's indeed still a problem. In fact, I was under the impression that lead was only added to solder to combat whiskers in the first place... Lead free solder might be a pain in the *** for the average DIYer who's used to leaded solder, but industry has moved on without issue.

Same here. I used to like the old Ersin Multicore stuff, but the modern version of it is not the same.

Very good, but the rosin flux doesn't smell like an old TV repair shop anymore.

The only times I have encountered a whisker is when the equipment has been exposed to moisture and is very old, the whisker does not occur in a couple of hours or so it will for special circumstances but in our homes there is no chance that it would happen but I do not know how you have it.
Nowadays I only use lead-free and there have never been problems, yes there are those who have happened for different things that have happened we do not know the circumstances for it to occur. But use the solder you trust when you are beginner it is always easier to use basic solder for electronic.

I have heard about hifi nervous but not solder nervous it must be something new. 😀😀

I have had to analyze some power supply failures, as we have over a thousand of them, and one failure brings down the entire machine.
Failure analysis helps us minimize recurrences.
Within the last few I autopsied, a selector switch had grown rather fuzzy, the classic tin whisker problem. So, that is roughly 4 years.
The environment the supplies are in are temp controlled to 1 degree C, and humidity is monitored as well, with no variations outside the consistent 45% give or take.
The tin is a plated surface, but forms whiskers in a very well controlled environment.

Lead has always been MUCH cheaper than Tin. Today's quote:
Lead USD/lb 0.91
Tin USD/lb 7.76
Tin is 8.5X the price of Lead. You want more Lead to keep the cost down.
Tin+Lead melts at a lower temperature than Tin or Lead alone. That's why you pay for 60% Tin.
Tin is often an "impurity" in raw lead (also Copper, and Tin-rich ores). Ancient metallurgists noticed that some "Lead" melted easier than others. As they learned to separate the Tin and make deliberate mixes, they found the ~~60:40 mix with the lowest melting point, which eased many soldering chores.
For rougher work like roofing and plumbing (literally "lead"), high-Lead solders are usable and much cheaper; also 50:50 solder has a long pasty phase where it may be "wiped" into a smooth joint. (Of course Lead in plumbing is now history...)
In any case, it is not the pig's fault, but who feeds him .....
Lead pipes for water transportation have been banned, and I guess rightly, beyond the cost of it vs. plastic.
But in which country is it severely penalized to throw the spent batteries into the river from the boat when they were exhausted?
I have seen it in person and they have laughed in my face when I was able to approach these antisocial people.
I believe that there comes a time in life when one ends up accepting that education cannot do everything (I do not say it is not important), there are good people and people who do not deserve to be born.

Those that are too clever by half are the last to admit it.
Some times I do push the envelope for the fun of it.
How about you Ed?
Thanks DT

The market has reacted to concerns re:- the eviroment,Unfortunatly the resulting product is simply not as user friendly.
