 - Set the soldering iron's temperature to *much* higher than normal, as the pads are large and shed heat quickly, and cold solder joints here will result in poor electrical connections
 - Apply the right amount of solder to ensure a good connection and good mechanical strength, but not too much that it makes it easy to form cold joints
