Ugh, I'm with you but don't ever make the mistake of repeating this in front of old dudes that played with CB radios in the 70s unless you like pointless tirades.

I hear you. We used to ride the old timers who always had flux tins in their arsenal even though there were cases of rosin core solder in the parts department.

Carn-farnds ya, you young whippersnappers!!   ;D

I'll give that a go! Thanks!

I need to watch some tutorial videos on how to do it right. I plug in the iron, let it get hot, touch the end of the wire and end of the solder together to mount it on the PCB, hope it makes a nice shinny melted ball that hardens, and repeat. In the end, it works, but I'd like to make sure it will stay working.

My technique must be way off or my "rosin core" solder must be crap or something. I wasn't getting very consistent solder joints, probably about 50% would turn out like crap. So I obtained some flux, dab a little smidge on with a fine brush or swab and my solder jobs are much much cleaner. Out of a recent 46 pin solder job, only one or two weren't very clean. I'm inclined to think exhaustion probably had more to do with the "unclean" joints. The only drawback is I must clean it off.  :-\ I probably should find some no-clean flux and see how it works.

I mean, how long is rosin core solder expected to last before it "expires"? Five years? 2?

I use a $15 Radio Shack grounded soldering iron.  15 Watt I think.  It's more technique & proper solder (lead) than anything else.

Use sand paper to scuff the battery a little and then solder quickly.

But most people probably don't have 15-20 year old rosin core solder lying around I guess...  ;D

I have a roll of rosin core solder that I use on occasion. It's from the 1960's and it works better than the stuff I get from radio shack.  I mostly use it for larger wire that's hard to twist together.  Haven't had a problem with the rosin drying out.  I see the drying around the cut edge of the strand but once I melt past that I've got brand new solder.  Well, 50yrs old new.  Awesome stuff.
