12-Zone Lead-Free Hot Air Reflow Oven JA-F12
Currency:
The 12-Zone Lead-Free Hot Air Reflow Oven JA-F12 is a large-capacity oven for high-throughput SMT and PCBA lines. 24 independent heating elements and Siemens PLC + IPC control deliver uniform, stable profiles for complex boards. Pairs well with our solder paste. Part of our Reflow Oven range.
Key Features
| Key Feature | Description |
| 12-Zone Heating System (24 Elements) | 12 independent heating zones with 24 elements (UP 12 / BOTTOM 12), each with individual temperature and switch control. Provides the precise thermal profiling required for complex BGAs, QFNs, and mixed-component assemblies. |
| New Energy-Saving Furnace Design | 4-sided return air circulation design ensures optimal hot air convection, best-in-class temperature uniformity (±1~2°C), and faster thermal compensation — reducing energy consumption during continuous production. |
| Plug-In High-Temperature Motors | Imported plug-in type high-temperature motors allow quick replacement in under 5 minutes, minimizing maintenance downtime and ensuring continuous production reliability. |
| Siemens PLC + IPC Control System | Dual-architecture control: Siemens PLC for real-time machine performance, combined with a professional Industrial PC (IPC) running Windows 7. If IPC crashes, PLC continues offline — production is never interrupted. |
| Mesh & Chain Conveyor System | Precision mesh and chain transmission controlled by computer for smooth, shake-free PCB transport. Stepless frequency converter speed control (0.35–1.5 m/min), accuracy ±2 mm/min. Rail width adjustable 50–400 mm. |
| Forced Air Dual Cooling Zones | 2 independent cooling zones (UP 2 / BOTTOM 2) with axial fan forced air cooling ensure rapid, uniform heat dissipation from boards after reflow — preventing component thermal stress and deformation. |
| Automatic Cylinder Body Lifting | The furnace body lifts automatically via cylinder for safe, convenient access to the internal heating chamber for inspection, cleaning, and maintenance. |
| UPS & Auto Delay Shutdown | Built-in UPS and automatic delay shutdown system protect PCBs and the machine in the event of power failure or overheat — preventing component damage and ensuring safe shutdowns. |
| Nitrogen Option Available | Optional nitrogen atmosphere module for oxide-free, void-minimized soldering — suitable for high-reliability applications requiring inert atmosphere reflow. |
| Comprehensive Alarm System | Multi-mode alarms: abnormal temperature (extra-high / extra-low), board-dropped alarm, and 3-color tower light (Yellow = Warning, Green = Normal, Red = Abnormal) for clear operator visibility. |
Product Description
The JA-F12 is a large-capacity, 12-zone lead-free hot air reflow oven engineered for high-throughput SMT (Surface Mount Technology) and PCBA production lines. Featuring 24 independent heating elements (12 top / 12 bottom), the F12 delivers exceptional temperature uniformity and thermal stability across the full PCB width — making it ideal for complex, high-density assemblies in demanding industrial environments.
Powered by a Siemens PLC + professional IPC (Industrial PC) dual-control architecture running on Windows 7, the F12 combines precision process control with a user-friendly bilingual interface. Its new energy-saving furnace design with 4-sided return air circulation, plug-in high-temperature motors, and forced air cooling system ensure consistent, high-quality lead-free solder joints with maximum production uptime.
