The precision oven is designed for aging, drying, and baking semiconductor devices that require a dust-free space. It is integral, with supporting feet, and easy to move. The workshop of the drying oven is made of stainless steel material and filled with environmentally friendly aluminum silicate fiber cotton in the middle, which is durable. It uses high-efficiency and energy-saving heaters, a reasonable air blowing system, and a complete control system to make the temperature of the workshop more uniform. Adopting a dual digital temperature controller, it is eye-catching and intuitive,PIDAccurate temperature control, no temperature shock phenomenon. Equipped with timed control function and secondary over temperature protection function. The control box is located on the upper part of the machine for easy operation. Front air outlet method addedHEPAFilter, ensure cleanliness100Grade.
