Soldering Path
Hands-on Skills Logical Thinking
What We Are Doing
By using a soldering pen, solder wire, and various components
we perform soldering on the integrated circuit board
to complete the circuit connections
and check the circuit continuity using crocodile clips with positive and negative terminals
Life is a Challenge
Continuously trying new things
In the last lesson, we discussed the functions of various components and their circuit symbols. By understanding these, we can determine the positions of components on the integrated circuit board.
Soldering Wire is a Challenge
Soldering wire is not as simple as it seems!!!
The temperature of the pen tip and the angle of inclination
The pressure and duration of contact with the solder wire
Calm and Determined
The connectivity between components and the uniformity of the solder wire are also factors we need to consider; otherwise, we may encounter issues like intermittent connections, looseness, or even short circuits, which we definitely want to avoid.
