Nitrogen Lead-Free Formic Acid Reflow Oven — A12N

The components adopted for the main electrical parts and the temperature control design reach an advanced level with high uniformity, making it suitable for the soldering of CSP and BGA components. The furnace liner features an energy-saving design with a heat-insulating and airtight structure, ensuring excellent thermal insulation and low power consumption (the average power consumption of reflow ovens in the industry is 15 kW per hour, while the average power consumption of the A9N is only 8.5 kW per hour), achieving a 40% energy reduction. Calculated based on 24 hours of operation per day, it can save more than 50,000 RMB annually. The self-developed software system is stable, reliable and powerful, which enables real-time temperature measurement and monitoring of PCB boards online, conducts data analysis at any time, and supports data storage and printing. Each temperature zone adopts forced independent circulation and independent PID control, with separate upper and lower heating methods, ensuring accurate and uniform temperature in the furnace chamber with large heat capacity. Rapid temperature rise: the time from room temperature to operating temperature is ≤ 20 minutes. Imported high-temperature and high-speed motors ensure stable air supply with low vibration and low noise; the aluminum alloy guide rails are treated with high-temperature processing to prevent deformation. It is equipped with a power-off protection function, with a built-in computer and transmission UPS to ensure the normal output of PCB boards after power failure and avoid damage. The furnace liner is made of stainless steel, which is corrosion-resistant and free of slag falling, protecting the cleanliness of PCB boards during the soldering process. Automatic monitoring and display of equipment working status. Custom-designed wind wheels ensure stable air speed; the hot air speed of the furnace body is adjusted by frequency conversion, and the thermal shock degree is controllable. Forced air cooling is adopted with a pressurized forced air cooling structure, featuring a long cooling temperature zone and excellent cooling effect. Circulating water cooling: cooled by an external industrial water chiller for uniform and rapid cooling; the cooling water temperature is adjustable, and the temperature of the cooling zone is displayable. A nitrogen flow meter allows real-time monitoring of nitrogen flow; an oxygen analyzer enables real-time monitoring of oxygen content, and the software records the changes in oxygen concentration. A water cooling module is added to the furnace chamber seals to reduce the operating temperature, extend the service life, ensure an excellent sealing effect and reduce the replacement frequency.
