Economic Lead Free Hot Air Reflow Oven A8 Up 8 Hot Air Bottom 8 IR Heating Zone PID Control
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 increasing temperature ramp up speed, improve the thermal efficiency. The special forced-air circulation system make PCB and the component heated uniform and eliminate the "shadow effect" completely.
2. Using special high temperature barrier structure for heat preservation and special iron in
3. Using imported Taiwan SanYue long shaft high temperature blower motor and W shaped heat duct, no noise & vibration, convenient for maintenance.
4. Heating zones with porous aluminum plate directing the hot air to guarantee the heat evenly distributed to the PCB. Hood can open completely so that convenient for cleanup.
No.2 Smooth and reliable transmission system
1. The conveyor system use STK adjustable speed motor imported from Taiwan matched with the 1:150 turbine reducer can running smooth, speed varies in 0-1000mm/min.
2. Independent roller structure support and match stainless steel mesh belt to make the running smoothly and the speed precision is up to ±20 mm/min.
3.Special stainless steel mesh belt: durable and wear-resistant, long lifetime.
No.3 Stable and reliable electrical control system
1. It adopts imported thermostat control which owns fuzzy logic and PID close loop system. It can fast response to temperature changes and ensure temperature compensation by PID intelligent operation.
2. Using thermocouple imported from Taiwan to each temperature zone, it can fast and sensitive response the changes in each temperature zone, feedback and control timely, compensate the temperature stability in each zone.
3. Special SSR solid state relay matched with dedicated heat dissipating block improve the heat efficiency greatly and prolong the lifetime effectively. Non-contact output and fuzzy control function by thermostat, can monitor the changes of environmental temperature, controlling the heating device by minimum pulse, ensuring the high precision of the temperature control & the uniform internal temperature. The length ,direction, temperature distribution, all these meet with IPC standards .
4. Heat energy is abundant, heat up fast, it’s only need 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 hardwares thermal damaged.
