Fact: when soldering electronics, you SHOULD use additional flux. Fact: One cannot use "too much flux." Between flux and solder, flux is more important than solder. If you have solder, but no flux? Put the iron away until you get more flux. Now: one CAN reach a point where, when one has both flux and solder, and yet, one is too tired to do more soldering without making mistakes and/or wasting components. HOW DOES ONE recognize this all to real, all too perilous state? It's not difficult, actually. WHEN you solder a junction together, and you see it is gleamingly, shiningly, perfect ... AND this then reminds you of your wife's perfectly pretty brown eyes ... THEN you KNOW it is TIME to unplug the soldering iron, put it away, and get some sleep. You can explain everything else to your wife, the next day, after you have had some sleep. Flowers help a lot, as does the ability to grill with charcoal. You can't go wrong with Salmon, seriously, because anything from "mildly warm but raw" to "fully cooked and crispy," it'll be good. You're welcome, SVTP ... wherever you are!
