How can i fix a problem if i over solder the connections. The solder is touching from terminal, where i think they should be isolated. But i can not seem to remove the excess solder without making a mess. I'm thinking that one of my problems is the cheap iron i bought is too big. The other problem is that i let my 7 year old son solder half the terminals. Or it is the board that i bought does not have enough space between the squares on the board causing it to be very easy to connect adjacent terminals.
