MINI series high-end hot air reflow oven parameters


Mini-led has smaller pads, less solder paste and smaller chips. It has higher requirements for the welding equipment cleanliness, temperature uniformity and other process parameters, and needs special MINI series high-end hot air welding equipment. The aero-engine turbine blade and eddy current technology hot air system and nitrogen heating technology are adopted, to ensure high quality and stability of the welding and meet the high requirements of MINI welding in the industry.


1. Efficient thermal compensation capability, customized hot air system to achieve the best thermal balance.

2. Multi-frequency converter control, fine temperature control, to achieve smaller welding spot temperature deviation.

3. New and upgraded flux recovery system, multi-stage filtration recovery, fully improve the recovery efficiency.

4. With nitrogen protection in the whole process, independent nitrogen control in each temperature zone, multi-point monitoring, the oxygen content will be within 200-500PPM.

5. Multi-cooling zones structure, with high power cooling system, improve cold and heat exchange capacity, to meet the cooling slope requirements of each process;

6. Super wear-resistant high stable special rail system, auto cleaning, to meet the furnace cleanliness requirements, and ensure product welding quality;
