Aim:
To learn about the soldering of electronic components and also have hands on experience of the same.
Objective: - At the end of this experiment the student should learn how to solder electronic components employing suitable precautions as not to have dry soldered joints.
A Brief on Soldering: -
Soldering is the process of a making a sound electrical and mechanical joint between certain metals by joining them with a soft solder. Soft solder is a low temperature melting point alloy of Lead and Tin. The joint is heated to an appropriate/required temperature by soldering iron. Soldering iron consists of a handle onto which is mounted the heating element. On the end of the heating element is what is known as the "bit", so called because it is the bit that heats the joint up. Solder melts at around 190oC, and the bit reaches a temperature of over 250oC. Soldering irons come with various ratings from 15W to over 100W.
Precautions: -
• The temperature of the soldering iron is considerably not enough to inflict a nasty burn. So, care should be taken during soldering.
• Do not give any supply voltage to the circuit; it is given just for practicing soldering.
