Never trust a pretty cone (rephrasing Amanda Lear :-) Sometimes when I
de-soldered one leg of, say, 0.5W resistor, the other leg would just
drop out from what looked like a good cone. Preventive reheating of
almost all solder joints with flux after each 5 years (5000 work
hours) seems to be a good idea for a single sided PCB with more or
less massive and hot components (CRT monitors for example)
