The idea for this project started when I got the T-962 reflow oven, after running a few tests I discovered that it had some hot-spots which meant some areas inside the oven were hotter than others and this could lead to trouble, you could get melted connectors in some places and cold joints in other places. Now it’s hard to tell how bad the situation is without doing some measurements so I decided to design & build this board which is capable of reading 10 thermocouples and logging the data. This way I could place the thermocouples inside the oven, something like a 3×3 or 4x2x2 matrix and I could get a sense of what’s going on inside the oven.
