This is the latest version of the Simon SMD soldering kit, the surface mount version of our popular Simon Kit. It's considered an intermediate kit for people who have soldered before and wish to learn how to solder surface mount components. Don't worry, we've added extras of the small components to help you out if you misplace a super tiny resistor.
