Reflow Soldering Hotplate

Soldering tiny SMD components can be quite challenging, but the process can also be automated. This can be done by applying soldering paste and baking it, either in a (reflow) oven or on a hot plate (like a cooking plate in your kitchen). Around the web, I’ve seen many DIY reflow ovens; in my opinion they have one big downside: they take up a lot of space. So I decided to build a hotplate instead.
The hotplate is fully programmable, so that any reflow profile can be added. The reflow process is then fully automated. Let’s get building!”
