Why can't the solder be soldered

Share us:

Specific how operate, hope friends can answer in detail

Need to help the flux to weld, such as welding a wire, wire end need to use an electric iron to solder the tin wire, solder pad also need tin, so it is very simple to weld the wire together, need to pay attention to the welding end must not have oxidation, otherwise it is difficult to weld.
