Characteristics of lead-free reflow soldering

1. Patented hot wire heating technology, small-scale lead-free reflow soldering, independent small circulation air transportation design, up-down heating mode, good thermal compensation, high thermal efficiency, power saving, fast heating speed, especially suitable for welding high-quality products such as BGA and CSP

2. Unique air duct design, imported spiral case air transportation with three-layer air equalizing device, uniform Phoenix transportation and high heat exchange efficiency

3. Preheating zone, constant temperature zone and welding zone are heated up and down, with independent circulation and independent temperature control. Temperature control accuracy of each temperature zone ± 1 ℃

4. The difference between adjacent temperature zones of lead-free reflow soldering can be up to 100 ℃, and there is no cross temperature. The temperature and hot wind speed of each temperature zone of small lead-free reflow soldering can be adjusted independently. The transportation adopts frequency conversion control, and the humidity control accuracy can reach ± 10mm/min, which is especially suitable for bga/csp and 0201 welding

5. It is suitable for debugging the temperature curves of various models. The lead-free reflow soldering has two or three soldering zones. The eight wire profile test △ t can be as low as 8 ℃, and the wiring curve test is especially corresponding to the small-scale reflow soldering lead-free soldering process of Japanese or European and American standards

6. Imported high-temperature motor is used to directly drive hot air heating, with good thermal balance, low noise and small vibration. 0201 components do not shift

7. The temperature of small lead-free reflow soldering rises rapidly, and it takes about 15 minutes from room temperature to the set working temperature. Lead free reflow soldering has fast and efficient thermal compensation performance, and the difference between the set temperature and the actual temperature in the welding area is less than 5 ℃

8. Modular design, compact structure, long-term convenient maintenance

9. Two independent micro circulation cooling zones, optional forced internal circulation cooling system and flux recovery system

10. The intelligent PLC temperature control system can realize the off-line function, and the system reliability is very high
