1. Control System Computer or Instrument control, make sure machine working steadily. 2. Hot Air Heating System 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 °C, room temperature settling time less than 20 minutes. 3. Cooling System Independent cooling area ensures the low temperature when PCB comes out. 4. Transmission system Use imported motors, speed adjuster, smoothly running, adjustable speed at 0-2000mm/min.

①　The heating system adopts SMT patented heating technology. ②　It adopts imported high-current solid-state relays with contactless output, which is safe and reliable. It is equipped with a special SSR heat sink, which greatly improves the heat dissipation efficiency and effectively extends its service life. ③　The heating components adopt imported high-quality components to ensure the high stability and reliability of the system, and can also guarantee a longer service life. ④　The modular design of the heating area is convenient for maintenance and disassembly. ⑤　It has temperature deviation, fault diagnosis, and sound and light alarm functions. ⑥　Independent small-circulation air supply design, upper and lower heating methods, good thermal compensation, high thermal efficiency, power saving, and fast heating speed, suitable for welding high-quality products such as BGA and CSP components. The special forced hot air circulation structure system makes the PCB and components heated evenly, with high efficiency and fast heating speed. ⑦　The air supply system adopts advanced air duct design, with uniform air supply and high heat exchange efficiency. ⑧　The preheating zone, welding zone and cooling zone are heated independently, circulated independently, and temperature controlled independently. The temperature difference between adjacent temperature zones can reach 3℃ at most, without temperature cross-talk. The temperature and wind speed of each temperature zone can be adjusted independently. ⑨　The imported high-temperature motor is directly connected to drive the hot air circulation, which has good hot air balance, stable operation, long life and low noise. ⑩　The power of each temperature zone is properly matched, and the temperature rises rapidly, from room temperature to the set working temperature in about 15 minutes. And it has fast and efficient thermal compensation performance. ⑪　Modular design, compact structure, and easy maintenance. ⑫　The independent cooling zone ensures the required low temperature when the PCB board is out of the board. ⑬　The transmission system adopts a variable frequency motor imported from Taiwan, with a 1:100 imported turbine reducer, which runs smoothly and the speed can be adjusted from 0 to 1500mm/min. ⑭　The independent roller structure and leveling support are adopted, combined with a stainless steel mesh belt, which runs smoothly and is suitable for BGACSP and other welding. ⑮　Special stainless steel mesh belt, durable and wear-resistant. It is not easy to deform after long-term use.
