Hello friends, I built a garage-made* SMT reflow oven in 2003, used a simple glass NTC as temperature sensor.
(*) we don't do those things inside "home", it is really made in the only place wife allow us to work on it, the garage, isn't it?

As a sensor, I used a common glass NTC to a small piece of a regular Printed Circuit Board, so it simulates exactly what the real boards are receiving of temperature.
