Soldering Made Simple

Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the filler metal having a lower melting point than the workpiece. Soldering differs from welding in that soldering does not involve melting the work pieces.

Introduction
Through hole soldering is when you have parts that go through metal holes in the printed circuit board

Nearly all my kits and other simple projects are done using through-hole parts. Practice and master this skill first, then you can move onto more advanced techniques!
