Introduction:
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 Stable and reliable conveyor 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
0-1500mm/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.
