Today we soldered two wires from a female power plug to some header pins as well as two more wires from a male power jack to a battery snap. The basic point of the lab was to simply make sure our solder job was good enough to where we could run a constant current through our wires. We learned the concept of pre-soldering and why it will save you time and hassle while soldering. We did experience problems with our solder not wanting to melt when we touched the tip of the soldering iron to it but that was simply because we had not tinned the tip of the brand new soldering iron yet. Tinning the tip of your new soldering iron allows for a better transfer of heat from the tip to your solder so lesson learned - always tin the tip of your new soldering iron before you try anything else.
