The components in the solder dont start to seperate, what you get there when you leave the heat on the solder for too long that it goes real tacky and brittle like is just the flux burning up, so if that ever happens all you need to do is add a bit more flux (this is where having extra to add comes in handy) will make the solder flow back to how it was when you first melted it off the roll and leave you with perfect results
All a cold joint needs in the end is some flux on it and a reflow

In which the solder is exposed to a heat too high for it to stay inert and the components in the solder start seperating. But I never leave it on the tip longer then a second or so. You can pretty much spot a dry joint by its discoloration and texture. A cold not will not be shiney and it will be convex. A dry joing just looks ugly. I usually tug on the joint to ensure its a strength afterwards. |
