Mastering the Art of Soldering
4. Creating Awesome Soldering Joints
4.1. General Guidelines for Soldering
While soldering, there should be at least 20 cm distance between the eyes and the board
and the soldering iron movement should be easy. An incorrect position can lead to fume
inhalation and back pain.
4.2. Soldering Through-Hole Technology (THT) Components
After introducing precautions and tools that are used with soldering process, we now
proceed to learning how to solder THT parts/components or through-hole-technology
soldering using a point to point soldering method. Let us begin with some definition of terms
and some terminologies.
4.2.1. Through-hole Technology or THT
Through-hole technology or through-hole soldering as the name implies (through-hole or
thru-hole) is the method when you build your electronic circuits by mounting or inserting
electronic component leads into holes drilled in printed circuit boards or PCB. The leads are
then manually or automatically soldered or affixed to pads on the opposite side of the board.
The electronic components used in this process are called THT components.
