Full hot air eight temperature zone lead-free reflow

Function

Inside the device is a heating circuit that heats air or nitrogen to a high enough temperature and blows it to a circuit board already attached to the component, allowing the solders on both sides of the component to melt and Bond to the motherboard. The advantage of this process is that temperature is easy to control, oxidation can be avoided during welding, and manufacturing costs are easier to control.

Product features

1. All temperature zones are heated separately up and down, independent hot air circulation, independent temperature control, and the temperature control accuracy of each temperature zone is ±1℃.

2. Modular heating structure can effectively prevent the influence of airflow in the temperature range, ensure that the components are heated evenly, and the lateral temperature deviation is <±2℃.

3. The opening of the upper furnace body adopts pneumatic jacking, which is safe and reliable and convenient for furnace cleaning.

4. Special long-life nickel-nosed heating wire type heat source, abundant power, rapid heating, less than 20 minutes from room temperature to constant temperature.

5. Adopting imported high-speed air-carrying motor direct drive for thermal cycle, low noise, low vibration and high thermal cycle efficiency.

6. It adopts Panasonic PLC industrial control products to control the upper and lower computer, which has first-class stability.

7. It has a delay switch protection function to prevent the transmission parts from deforming due to uneven cooling.

8. It has a power-off protection function to ensure the normal output of the PCB board without damage after power-off.

9. With over-temperature sound and light alarm and emergency braking system.

10. Simplified and traditional Chinese MMI operation interface and artificial intelligence software control, which greatly facilitates the use of users

11. It has a complete online temperature test curve and analysis, storage, recall and printing functions.
