Nitrogen Reflow Oven

  • Windows 7 Chinese and English systems, easy to learn, can be replaced at any time.
  • The digital control system adopts PLC and modular circuits, and the repetition accuracy is stable and accurate.
  • The Intelligent Diagnosis System (IDS) has functions of failure reminder, alarm, list, and data saving.
  • Temperature and fan speed can be controlled independently to meet high precision requirements.
  • The length of the effective heating zone, the heat conduction is fully and evenly distributed, which greatly improves the heating efficiency.
  • Forced cooling system, fast cooling speed, suitable for various lead-free solder pastes.
  • PLC and PID closed-loop control to achieve high-precision temperature control and repeatable curves.
  • Equipped with a patented air management system with 8 upper and lower zones as standard, making hot air convection more efficient and heat compensation faster.
  • The guide rail is hardened and more stable.
  • The width of the guide rail can be adjusted manually (optional: automatic adjustment by SPG geared motor).
  • The chain guide rail is lubricated by the central oil storage device and controlled by a computer.
  • The powerful software system can save all settings, and print all data and configuration files through the PC.
  • It has a flux collection system to keep the area clean and ensure more environmentally friendly emissions.
  • Nitrogen with the machine is optional.

Nitrogen system:
1. High-precision and reliable oxygen analyzer + cooling water
2. With a nitrogen flow meter and nitrogen pipeline
3. Furnace body sealing optimization design reduces nitrogen loss. An external chiller provides a high-quality cold source.
4. Prevent oxidation
5. Improve wetting force and wetting speed
6. Reduce solder, avoid bridging, and get good soldering quality.
7. Nitrogen flow controller: normal nitrogen consumption: 20m3/hr.500-1000ppm (oxygen concentration)
8. Fully automatic oxygen analyzer: fast response time; complete self-diagnosis and testing of important functions and parameters
9. Cooling water machine: 3HP; external; sufficient heat dissipation capacity to meet the requirements of a lead-free process
10. Flux management: The nitrogen furnace is equipped with an air circulation filter as standard to optimize the environment in the furnace and facilitate maintenance
