ApogeeKits Free Guide to Electronics Soldering
A FREE guide of hand soldering techniques for the beginner level hobbyist or student.
This guide applies to “through-hole” technology hand soldering practices and though most “surface mount”
soldering rules are similar, it does not address some specific intricacies of surface mount soldering practices.

Many people have never taken the opportunity to pick up a soldering tool and use it to assemble an
electronic project. If you fall into this category, then this paper was written for you, so that the door to the
fascinating world of electronics might be opened a little wider for your education and enjoyment.
Many of the same soldering skills used to assemble electronic projects or kits are also applied to component
removal or making service repairs. Lets examine the concept of basic soldering techniques used for plated-
through-hole (PTH) electronic component installation, beginning with the most fundamental tools needed to do
the job right.
Safety glasses (or at a minimum, your vision correction lenses if you wear any) are your most valuable
yet often forgotten or overlooked tool when performing soldering tasks. After all, it’s hard to solder if you can’t
see. The “smallness” of the job at hand, soldering a component lead to a circuit pad, especially on a printed
circuit board (PCB) crowded with other components that are “in the way”, often require
