There are a variety of materials required for the
through-hole soldering of axial leaded components. For this
type of placement and soldering, the following tools and
components are required:
Printed circuit board (PCB)
Axial leaded components
Soldering iron with chisel tip
Pliers (lead forming)
Before beginning the soldering process,
there are a few safety and electrostatic
discharge (ESD) precautions one needs to
take before soldering components.
Soldering tips get very hot (+445°F!) and
therefore are a very painful potential burn
hazard to some of the most sensitive parts of
your body — your fingers! Always assume the
soldering tips are hot! Make sure to wash
your hands after soldering prior to eating —
especially when soldering with tin-lead soldering systems.
While the safety aspect of soldering has to do with
protecting yourself from hot objects and foreign chemicals,
the other things that need to be protected are the devices.
While the majority of through-hole devices are passive in
While SMT (surface-mount technology) components are the predominant
type of package today, there still remain many through-hole components
that must be soldered on most mixed technology projects. This is typically
because these components have a better mechanical rigidity for interaction
with your project, or for higher voltage components such as some power
transistors or capacitors.
