In this first lab we were given a PCB and asked to solder
ten components on to the board. Before the class I had try soldering a little,
so I had a rough understanding of soldering before this class. However, I did
learn that before soldering you should touch the iron to the board and the wire
of the component for a few seconds to heat them up. Then take the solder and
touch it to where the iron meets the board so that it ‘melts’ onto the board
covering the entire, little copper pad. In constructing the 5V power supply we took and old cell phone charger and cut off the end that connected to the cell phone. From that we took the two wires that were inside the cable and soldered wires to the two wires inside identifying them as positive or negative. In this process I learned how to use a Digital Multimeter.
