I have an old roll of solder- not sure of its provenance, probably belonged to my late father in law- and it's marked 60%.... what does that mean?- Something to do with its composition I guess- lead?
Corollary to that: I have a reasonable soldering station (no name, Chinese, but seems pretty good) with adjustable temp. For that solder, is there a recommended temp?
(I've been soldering since about 1962 when I dropped hot solder on my bare leg, so I know it's hot but never really thought about the actual temperature. My late Dad had an Adcola back in the day...)
And final question: if I were to go buy a new roll of solder today, what should I ask for in terms of composition and what temp would that be soldered at?
Edit.... I suppose I should have Googled first... 60% is 60/40 lead/tin and i melts at 360.
