Core Advantages:
- Full process integrity: The bottom infrared preheating system is standard, and the heating ratio (0-100%) can be adjusted by computer to reduce PCB thermal stress, improve solder wettability, and reduce defects such as cold solder joints and cold solder joints.
- High-precision motion control: The XYZ axes all use Panasonic servo motors and drivers, with ball screws and linear guides, with positioning accuracy of ±0.1mm, stable motion, low noise, and adaptable to complex welding paths.
- Intelligent operation and traceability: The software system developed based on Windows 10 supports direct programming paths of PCB images, and real-time monitoring of key parameters (temperature, speed, pressure, etc.); standard real-time monitoring cameras can intuitively observe the welding process, and parameter configuration files can be stored and traced to ensure welding quality consistency.
- Flexible adaptability: The maximum welding area is 300×300mm (customizable), compatible with larger PCB sizes; the operating height is 900±30mm, ergonomic and reduces operating fatigue; the clearance above the PCB is 50mm, suitable for plates with raised components.
- Stable and reliable structure: The bottom of the steel frame is equipped with a base plate to enhance equipment stability and reduce vibration; the tin furnace is made of titanium alloy and is equipped with a nitrogen online heating system to reduce solder oxidation and extend service life.
Workflow:
1. Manual loading: manually place the PCB board on the motion platform.
2. Preheating stage: the PCB board moves to the bottom preheating position through the XYZ axis and is preheated by the infrared heater (temperature 25-240℃, time can be set).
3. Flux coating: the PCB board moves to the spraying area, and the flux is evenly coated on the welding point through the Japanese imported injection valve (the flux is stored in a stainless steel box with constant pressure).
4. Welding process: the PCB board moves to the top of the tin furnace, adjusts the position through the XYZ axis, cooperates with the nitrogen heating system of the tin furnace (temperature 0-350℃), and uses the wave crest to complete the welding (wave crest height, welding speed and other parameters can be set).
5. Manual unloading: after welding is completed, the PCB board is manually removed.

Advantages Over H3200
| Comparison dimensions | DEZ-H3600A | DEZ-H3200A |
| Process integrity | The standard bottom infrared preheating system can reduce PCB thermal stress and improve welding quality (especially suitable for thick plates and heat-sensitive components). | There is no preheating system, it only depends on the temperature of the tin furnace, and it is not adaptable to PCBs that need to be preheated. |
| Motion system | The XYZ axis is fully servo-driven (Panasonic servo motor + driver), with more stable movement, faster response, and higher positioning accuracy consistency. | The XY axis is a stepper motor + synchronous belt, and the Z axis is a servo drive, with slightly inferior overall accuracy and stability. |
| Applicability range | The maximum welding area is 300×300mm (customizable), which is larger than the 300×250mm of H3200; the clearance above the PCB is 50mm, which is suitable for more plates with raised components. | The maximum welding area is 300×250mm; there is no clear limit on the clearance above the PCB, but it is not optimized specifically. |
| Operational convenience | The operating height is 900±30mm, which is more ergonomic and reduces operating fatigue. | The operating height is 700±30mm, which is relatively low, and long-term operation is prone to fatigue. |
| Preheating control | The preheating temperature and time can be accurately adjusted by computer, and the heating ratio is 0-100%, which meets the preheating requirements of different PCBs. | There is no preheating function, and the preheating parameters cannot be adjusted. |
| Power and heating efficiency | The total power is 5kw, and the preheating system is heated independently, which can stabilize the temperature in advance and is suitable for complex welding processes. | The total power is 3kw, there is no preheating system, and the process support for multiple temperature curves is insufficient. |
