Tools and materials needed to solder You will need tools, like soldering iron, soldering wire, soldering paste (paste flux) or liquid flux and damp solder sponge and a circuit board, you can find a universal board as a carrier of soldering, or you can use

How to Solder a Circuit Board. Next, let’s see how to solder through-hole components to a circuit board. Start by placing the component into its holes. Place it so that its legs come out on the same side as the solder pads. On the solder side of the boa

Soldering components onto a circuit board when the leads can be pushed through holes in the board is the easier of the two methods of soldering small components onto boards. Many circuit components need to be surface mounted on circuit boards, which force
