Lead-free reflow soldering series brings the concept of environmental protection and energy saving into the new design.
The new cooling structure design reduces the heat loss while making the flux recovery more thorough.
It has the excellent characteristics of ultra-low power consumption and easy maintenance.
Higher transmission reliability, better system stability and improved heat transfer efficiency allow for lead-free processes for larger and more complex welded products.




In the Surface Mount Technology process, Hot Air Reflow equipment provides an optimized lead-free, lead-free Soldering process, which has been highly favored in terms of low energy consumption and high productivity.



Hot Air Reflow adopts advanced production process control, provides strong equipment and process guarantee for production and processing, and provides "valuable products and services" for enterprises. It is a full-featured and cost-effective product in the industry.
