Almost every technological product—whether laptops, smartphones or vehicle-mounted control systems—cannot do without sensitive electronic components. Ensuring good contact of components on circuit boards through high-quality soldering processes is crucial to the proper operation of these products. Therefore, Rehm is committed to building high-quality reflow soldering systems for customers.
Rehm VisionXC reflow soldering system features mature technology and first-class manufacturing. Adopting a convection design, it transfers heat via airflow—with two options available: air or nitrogen. As an inert shielding gas, nitrogen is the ideal heat transfer medium and can also prevent oxidation during the soldering process. The modular design provides maximum application flexibility for your production line.
Do you need a soldering system that can precisely meet your personalized production requirements? Do you need to process sensitive electronic components at specific temperatures? We can meet all your needs and provide you with a variety of personalized system solutions.

Choose Rehm to meet all your application needs!
VisionXC can provide optimal solutions for different production environments and conditions to achieve the best soldering process. Depending on the system type, you can select process zones of varying lengths. In addition, the preheating zone, high-temperature zone and cooling zone feature the same pitch, supporting modular configuration and deployment. A wide range of functional options are available to meet your diverse application requirements.
• Modular and flexible system
• Energy-efficient and high-performance with minimal carbon dioxide emissions
• Stable lead-free soldering process
• Minimal downtime and maintenance requirements
• Intelligent software tools for maximum traceability
• Minimal total cost of ownership
During the soldering process, electronic components pass through each zone of the system in sequence: from the preheating zone through the high-temperature zone to the cooling zone. For continuous processes, safe component transmission is particularly critical. Therefore, we provide you with a highly flexible conveyor system.
Our conveyor system can perfectly adapt to your components regardless of the circuit board geometry. In addition, both the conveyor track width and speed are flexibly adjustable, enabling parallel dual-track soldering (synchronous/asynchronous) within a single reflow soldering system. Depending on specific requirements, you can select different transmission modes, such as single-track and dual-track transmission, four-track or multi-track transmission, as well as mesh belt conveyor systems.
When soldering large circuit boards or flexible substrates, the optional central support system prevents component deformation and ensures maximum process stability.
• Parallel transmission for reliable and trouble-free production
• Precisely adjustable conveyor width
• Temperature profile unaffected by the conveyor system or central support system
• Conveyor system drive mechanism located outside the furnace chamber, resulting in minimal maintenance requirements
• A variety of conveyor systems available to suit all applications
• Integrated central support plate for maximum process reliability
Although different products have different process requirements, optimal thermal conductivity is the foundation for achieving excellent soldering results for all products.
The VisionXC series reflow soldering system is equipped with flexibly adjustable preheating zones for preheating PCB boards to the temperature required for actual soldering. In addition, each zone of the system can be independently controlled by adjusting the fan frequency to ensure optimal results.
VisionXC is fitted with a special air straightener to ensure uniform airflow across the PCB board for optimal thermal conductivity. Furthermore, you can adjust the gas flow rate of the top and bottom heating zones separately to ensure that components are heated completely and evenly, preventing material stress from interfering with the soldering process. At the same time, it ensures that small components do not overheat and large components are sufficiently and thoroughly heated.
To stabilize the airflow in the system and minimize outward heat radiation, VisionXC adopts optimal thermal insulation measures between the furnace chamber and the outer wall.
By creating precise and reproducible temperature profiles, our system can perfectly meet your process requirements and match your component dimensions, materials and other process parameters.
Like all industrial processes, SMT production lines also generate residues that may contaminate the system, so these residues must be promptly discharged from the process cycle. Our high-efficiency residue management system can safely and reliably purify process gases, keeping the system clean and dry.
Liquid residues are first condensed and filtered in the cooling zone unit before being discharged. The filter unit is easy to clean, and the filter can be directly replaced through the back of the system without opening the furnace chamber. An optional seven-stage filtration is available, with a maximum filtration efficiency of up to 98%.
• High-efficiency cleaning to ensure a clean and dry furnace chamber
• Integrated system solution
• Reliable and stable process
• Easy to operate
• Low maintenance requirements

A high-performance cooling system is essential for optimal soldering results and gentle cooling of components.
Rehm offers a variety of cooling systems for VisionXC, with precise fine-tuning capabilities to adapt to personalized production processes. The standard water-cooled solution with heat exchanger and adjustable ventilation system can operate as a closed-loop system for efficient cooling. For large, high-density PCB boards, you can opt for the bottom cooling system.
• Stress-free cooling achieved via multiple independently adjustable fans in the cooling zone
• Optional bottom cooling system for perfect cooling of large, high-density components
• Multiple cooling options supporting flexible configurations
• Innovative and sustainable liquid nitrogen cooling technology
When switching production lines, adjustments to production process settings are usually required. When switching from a higher temperature profile to a lower one—such as transitioning from lead-free soldering to leaded soldering—the system requires a relatively long cooling time. To achieve faster cooling, Rehm offers a variety of optional features to reduce waiting time.
Rehm has developed the straightforward ViCON software for the VisionXC reflow soldering system, providing you with an intuitive operating experience via a touch screen.
Through the equipment view on the main interface, you can easily access all information, commands, and parameters. ViCON offers a range of outstanding features, such as a freely configurable favorites bar, structured parameter grouping, independent process tracking and archiving, etc., providing optimal support for your production process.
During the software development phase, Rehm experts made in-depth improvements in many areas, including product management—for example, supporting the creation of new products or copying specific attributes while production is in progress. Additionally, parameters can be directly set when creating new products, which means production can be launched more quickly without any interruptions.
Similarly, you can immediately identify the system's operating mode based on the working status, detect errors more quickly, and reliably evaluate alarm information.
Another major advantage of the ViCON software is its support for user management. By flexibly assigning user roles, each user can obtain corresponding operating permissions—no strict hierarchy is required.
• Intuitive software operation with touch screen
• Clear product management supporting offline programming
• Parameter transparency through module grouping
• Favorites bar for easy adaptation to different processes
• Multi-language support
