Today I finished a spool of Sn60/ Pb40 solder with 3.3% flux, 0.8 mm diameter. Now I'm using solder that is Sn63/ Pb37 with 1.1% flux, 1mm diameter. Comparing the brightness of the previous solder joints to what I am making now with the new spool, the previous joints are much more shiny. In fact by comparison the joints prepared with the new spool are quite dull. I'm heating the joints the same as before. Should I be concerned about the new joints being less shiny, or is this just because of the lower percentage of flux?
Putting together a circuit that I don't want to spoil after a lot of developing it,
