Sino-micro Nitrogen Reflow Soldering oven

Sino-micro Nitrogen Reflow Soldering Oven Equipment Advantages:

This advanced Sino-micro Nitrogen Reflow Soldering oven system has been adopted by global industry leaders such as Huawei and Foxconn, demonstrating its reliability and performance in demanding manufacturing environments.

Technical Specifications:
– Vacuum Performance: Achieves a vacuum level down to 1 mbar.
– Temperature Uniformity: Maintains exceptional temperature consistency with deviations of ≤±0.3℃ across the process zone.
– Full-Process Nitrogen Protection: Incorporates cutting-edge nitrogen shielding technology, introducing high-purity nitrogen (oxygen content ≤50ppm) during soldering. This effectively prevents component oxidation and significantly enhances solder joint quality.

Core Value Proposition:
Delivers outstanding process improvements by dramatically reducing void formation rates to ≤2%, ensuring superior product integrity and reliability.

 

Sino-micro Nitrogen Reflow Soldering oven uses advanced inert gas protection technology to inject high-purity nitrogen (N₂) during the welding process, effectively reducing oxidation and improving solder joint quality. It is especially suitable for high-precision electronic assembly (such as PCB, SMT patch, BGA package, etc.). The equipment has the ability to accurately control temperature, uniformly heat and control low-oxygen environment, making it an ideal choice in the field of electronic manufacturing.
