How can I spot a discouraging solder reciprocated?

Answer:

The solder have not flowed onto and around the joint, but is a short time ago sitting on top of it resembling a bead. To get a honest joint, you enjoy to transfer some boil from the iron into the leads man soldered, not just to the solder. The opinion is to get the solder to flow into and soak the cohesive before solidifying.
The solder should be shiny and here should be evidence of flowing solder.
A bad solder integrated will appear as flat or dull in color, be as a good integrated will be bright and shiny. A dull looking joint is call a cold joint and will not hold as strongly.
