No.1 The unique advanced long life heating system
1. The heating system adopt the Swedish nickel heater with efficiency and energy-saving. The peak wave length of the radiation power is 4UM with curved surface reflector enhance temperature ramp up speed, improve the thermal efficiency. And the special forced-air circulation system make PCB and the component uniformly heated and eliminate the "shadow effect" efficiently.
2. Using special high temperature resistant protection material in heating preservation structure and cast iron in heating passage.
3. Using imported Taiwan SanYue long shaft high temperature blower motor and W shaped heat duct, critical design for no noise or vibration and convenient for maintenance .
4. Heating zones are structured with porous aluminum air director, hot air is uniformly distributed to the PCB surface. Hood can open completely so as to easily proceed maintenance.
No.2 Smooth and reliable transmission system
1. The conveyor driving system use STK adjustable speed motor imported from Taiwan matched with the 1:150 turbine reducer can running extremely stable, speed range can varies between 0-1000mm/min.
2. Independent roller structure support and mesh belt running smooth and the speed precision is up to ±20 mm/min .
3. Mesh belt: durable and wear-resistant, not easy to deform and long life.
No.3 Stable and reliable electrical control system
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.
