Features: Control system:Computer or Instrument control,make sure machine working steadily. Hot air heating:Both top and bottom zones hot air heating,good heater compensatory,High thermal efficiency,energy saving,speedy heating,suitable for soldering components like BGA, CSP etc. Special forced hot air circulation structure makes PCB and components heat evenly, Temperature Accuracy ± 1.5 , room temperature settling time less than 20 minutes. PID intelligent precision controller,automatically control heating volume, fuzzy control function changes the external heating fast,and by internal control ensures more balanced temperature. Use imported big current solid relay,without touch point output,safe,reliable,with special SSR radiator,greatly improve thermal efficiency and lifetime. Temperature protection: ETA using third-party over-temperature protection, multiple layers protection to ensure safe operation. Products comply with CE, CCC, UL and other standard or specifications. User-friendly design: fault detection (such as heaters abnormal alarm, etc.), regular maintenance reminders, the economy functions and tool-free maintenance, reducing equipment failure rates. Main parts:Imported main parts ensure equipment runs smoothly and lower the maintenance cost.
