HW-R10 Reflow Oven
The HW-R10 is a large ten-zone, rail-type SMT reflow oven from China SMT machine manufacturer HWGC. It melts solder paste on PCB pads through forced hot-air convection to join components to the board. Twenty independently controlled zones, ten above and ten below the conveyor, span a 3,940 mm tunnel, with a 500 mm mesh belt, a 50-380 mm adjustable rail and 0-2 m/min transport. PID plus SSR control holds ±1-2°C static accuracy up to 300°C for lead-free and leaded PCB assembly.
Key Features
- Twenty switchable heating zones (10 upper, 10 lower) reduce startup power
- Rectified jet hot-air heating for strong, uniform heat transfer
- Two-zone forced-air cooling with adjustable fan speed, water cooling optional
- External flux recovery with two zones at tunnel inlet and outlet
- Mesh belt, rail chain or synchronous mesh-and-rail conveying
- 3°C/s ramp, ≤0.5 s thermal recovery, three-channel profiling
- Siemens PLC with daily logs, production reports and alarm records

SMT Industry News
Demand for AI server boards and other high-end computing PCBs is putting pressure on SMT capacity, and those assemblies are large, thick and heavy on copper, so they absorb a great deal of heat. Twenty independently controlled zones, a 3,940 mm tunnel and 3°C/s ramp capability help factories hold a repeatable lead-free profile on heavy boards without slowing the line. Smart factory and Industry 4.0 projects are also spreading across SMT production lines, with MES connectivity and real-time process data expected as standard; the HW-R10 feeds that layer with Windows control, daily logs and profile recording.
Applications
The HW-R10 suits medium and high-volume PCB assembly in SMT production lines, especially large boards and high-thermal-mass assemblies where tunnel length and even heat distribution matter. Typical users include consumer electronics, power supply, industrial control, automotive electronics and LED lighting factories running several board variants on one line. As a rail-type SMT reflow oven for lead-free soldering, it offers a repeatable, documented process backed by a responsive China SMT machine manufacturer.
