Surface mount soldering is the way to go for small footprint projects and multiple production runs. However, surface mount components arenâ€™t always the most friendly for a soldering iron setup. Imagine a surgeon trying to operate with bulky leather gloves on and you kindÂ of get the picture for what happens when you try to solder a handful of closely-spaced 0402 or 0603 chip resistors with a soldering iron. Hot air soldering is the solution for these tiny components. With hot air, you basically have two choices, a hot air rework station or a reflow oven.
Kevin wanted to take the next stepÂ for his home electronics workshopÂ but didnâ€™t want to go all out and buy an expensive reflow tool that wouldnâ€™t get frequent use. After some Internet research, he decided to go the route of using an old toaster oven, a solid state relay, an Arduino, and a reflow oven shield for his build. Check out the projects wiki for all of the details of his build.
