The ERSA HOTFLOW 3/20 SI Reflow Soldering Oven is a premium high-capacity SMT reflow system engineered for manufacturers requiring exceptional soldering quality, high throughput, and intelligent process control. As one of ERSA’s flagship reflow solutions, the HOTFLOW 3/20 SI combines advanced convection technology, precise thermal management, and Industry 4.0 connectivity to meet the demanding requirements of modern electronics manufacturing.
Designed with 20 independently controlled heating zones and optimized multi-stage cooling, the HOTFLOW 3/20 SI delivers outstanding thermal uniformity across the entire PCB surface. Its highly efficient forced convection system ensures even heat distribution while minimizing thermal stress on sensitive electronic components. This enables manufacturers to achieve superior solder joint reliability for complex PCB assemblies including BGAs, CSPs, QFNs, PoP devices, fine-pitch ICs, and large multilayer boards.
The SI (Smart Intelligence) platform incorporates advanced software that continuously monitors temperature stability, airflow performance, conveyor speed, and production parameters. Intelligent recipe management allows operators to quickly switch between products while maintaining consistent soldering quality. The system also supports comprehensive process traceability, making it ideal for automotive, medical, aerospace, and industrial electronics production where quality documentation is essential.
Energy efficiency is another major advantage of the HOTFLOW 3/20 SI. High-performance insulation materials, optimized airflow channels, and intelligent heating control significantly reduce electricity consumption without compromising production performance. The oven supports both lead-free and traditional soldering processes and can be seamlessly integrated into fully automated SMT production lines.
Every refurbished ERSA HOTFLOW 3/20 SI supplied by Fuliu undergoes a rigorous refurbishment process including heating module inspection, blower balancing, conveyor calibration, thermal profile verification, electrical testing, software diagnostics, and continuous production simulation. Fuliu also provides turnkey SMT line planning, installation, commissioning, operator training, spare parts support, preventive maintenance, and lifetime technical service to ensure reliable long-term operation.
