I am just coming to the end of my old 60:40 tin/lead fluxed solder
and after a quick look it seems that
old style solder is not easy to find - if at all.

I did read something about this months / years ago, saying it is not
as easy to use, but forgot to stock up at the time

Can anyone bring me up to date with the new stuff, suitable fluxes
or whether the old stuff is actually available.

I don't use much, generally for small PCB repairs and every
soldering, so a 500 gram would last me ages

Thanks,
Nick
