Soldering Techniques
Soldering is an important skill for electrical technicians. Good soldering is important for the proper operation of equipment.
Solder is an alloy of tin and lead. The solder used most is 60/40 solder. This means it is made from 60% tin and 40% lead. Solder melts at a temperature of about 400 °F (205 °C).
For solder to adhere to a joint, the parts must be hot enough to melt the solder. The parts must be kept clean to allow the solder to flow evenly. Rosin flux is contained inside the solder. It is called rosin-core solder.
A good mechanical joint must be made in soldering. Heat is applied until the materials are hot. When the materials are hot, solder is applied to the joint. The heat of the metal parts (not the soldering ...
