* it adopts multi-point blast principle,full-range microcirculation structure and upper and lower heating means;the air range in the heating area is short but has high heating efficiency.

* it adopts high efficiency pressurized air duct that can provide sufficient circulation air flow;no temperature interference occurs in each temperature zone.

* special imported long-life winding nickel-chromium heater thread is adopted so that high thermal efficiency and sensitivity,small thermal inertial can be achieved;the temperature control precision of each temperature zone is within + 1℃;air can be heated and circulated;temperature rise is fast and it takes approximately 15min to reach the set temperature from room temperature.

* it adopts imported high-temperature motor that can be connected directly to drive hot air to heat;equal hot air,low noise and slight shock can be achieved.

* there are two compulsory cooling zones set.one can reach --5℃/s cooling speed,which can meet the requirements of various lead-free production processes;the industrial cold air machine can be used to conduct compulsory cooling.

* the special transportation guide rail is adopted;it is made of temperature-regulation and wearable aluminum alloy,so it has high rigidity and cannotbe distorted easily.

* the transportation system adopts transducer stepless variable frequency speed regulation and is equipped with ups power supply and manual shake-out function,so it can effectively prevent the pcb board from being burnt in the hearth during sudden outage.

* it is set with automatic oil dipping function.

* the whole system adopts siemens plc+dell computer control,with standard lcd screen and windows xp operation system;so it has flexible curve test and powerful dynamic curve analysis function.

* all electric components are imported and all signal cables undergo screening treatment,thus the whole control system is more stable and reliable.
