For the latest MMDVM_HS_Hat project by me and Mathis, DB9MAT I arranged for a reflow oven model T-962 which is a good assistant for SMD soldering work. As per Toufik, F0DEI there were some interesting modifications to make in order to improve the results as well as to get rid of smelly evaporations.
There is a famous article on hackaday (See ). It was the reason to open up the unit and get some improvements done. In order to support this there is a nice YT video  describing the mods in detail.
