What Causes Solder Balls During Hand Soldering?
To many operators believe the old myth that flux is your friend and you can never have to much flux. That is not true as to much flux will outgas at the end of the hand soldering process creating solder balls around the connection. This is one possible explanation as others have stated other causes as well.
