Combi Steam Oven

At the start, we had to overcome EMC issues, caused from the connection of the metal oven connected to the ground. We tuned the microchip controller until there were no more ghost touches. The controller is integrated to the customer`s PC-board. The customer consigns 23 variants of glasses. Due to uneven quality of the cheap glasses, OCR bonding is used for the touch bonding.
