Today's Topic: Introduction to Soldering and making my own 5V Power Supply.
Tonight, we learned about how to solder electronic components to a solder board and to solder two wires together.
At first, the class was to solder around 20 components to the solder board. However, I ran out of time and I was only able to solder 7 component to the solder board.
The component should be either parallel to the board or perpendicular to the board, but never tilted at an angle!!
According to the course material, the solder should be melted and cooled to a shiny conical shape. At the same time, the solder should cover the copper on the solder boarder. As a hint from the experts, ALWAYS put flux to clearn the surface for soldering.
Not the best conical geometry, but still conical and shiny! Caution: Do not forget to trim the lead after soldering.
Covering the specific copper surface with solder.
The second project of the day was to solder a loop of wire. First, the wire was cut into 3 sections and 6 parts. The wires are connect in series. At the end of each sections, the rubber insulator were to be striped. Then the copper wire of two sections were to be put side to side parallel to each other. At last, they can be soldered together.
Unfortunately, my loop was broken because I had cut too deep and damaged the copper wire inside when I was stripping the wire.
The soldered connection survived the test but not the partially damaged copper wire.
After soldering two wire together, wrap a heat shrink around the joint and apply heat to it to let the shrink and hold onto the wire. the heat shrink will insulate the copper wire from outside.
I was unable to complete the 5V power supply on time nor finish repairing the wire loop. But they will be done the next day.
