The Control system of Reflow Oven Equipment
1. It adopts imported thermostat control which owns fuzzy logic and PID closed loop control system. It can quick response to the changes in heating condition and ensure efficient heat compensation to achieve required temperature.
2. Using thermocouple imported from Taiwan to every heating zone, it can rapid feedback changes in each temperature zone, real-time monitoring to maintain the temperature in each zone.
3 .Special SSR solid state relay matched with dedicated heat dissipating block prolong the lifetime effectively. No contact output and fuzzy control function by thermostat, can monitoring the changes of environmental temperature and calorific value, applying the heating device by minimum pulse, ensuring the high precision of the temperature control & uniform temperature within zones. The zone length, flow direction, temperature distribution, all these are meet with IPC standards.
4. Powerful heating elements, heat up fast, it’s only need approx. 20 minutes from room temperature to set-point temperature.
5 .Failure diagnosis, visual & audio alarm.
6. Delay shutdown production function, uniform cooling after the shutdown: prevent hard-wares from any thermal damaged.
