Uniform-temperature oxidation diffusion furnace

product introduction:

Configuration details

Equipment features:
n1. Uniform temperature field, length and precision of constant temperature area: 300 ~ 1250mm, 800~1200℃±1℃
n2. With powerful software functions and NBD-101EP embedded operating system, users can easily modify process control parameters and display various process states at any time;
nEquipped with fault self-diagnosis software;
n3. The program can realize manual/automatic work. After power failure or halfway shutdown, it can be started again to manually heat up according to the process, saving the process time;
n4. It has a variety of process pipelines, which can be easily selected by users;
n5. Cold end detection of ambient temperature for temperature compensation, to avoid environmental temperature change, impact on furnace temperature, to avoid inter-layer interference;
n6. Multiple PID parameters can be stored for system operation and call function, with multi-point temperature compensation
n7. Precise digital control of gas flow, closed-loop control of analog signal, separation of strong and weak electricity, standard bus for various data interactions, to improve anti-interference ability and ensure data safety;
nGas opening has slow start function;
n8. Multiple alarm functions and safety protection functions;
n9. Automatic adjustment of constant temperature area and cascade control can accurately control the actual process temperature of the reaction tube;
n10. Automatic pressure adjustment technology introduces pressure parameters into crystal silicon oxidation process, which effectively reduces the interference of tail exhaust on the process and reduces the process fluctuation caused by exhaust
