Modular system concept – ideally matched to your manufacturing environment

Flexibility is in greater demand than ever before in modern electronics manufacturing. A modular system concept provides for high levels of flexibility in production. The systems included in the VisionX range are distinguished by their modular design, and they’re available in various lengths and with different conveyor variants. Depending on throughput or product diversity, you can change your production line over to the required system at any time.

The modular design saves time and reduces costs because your system is ideally matched to the production of customer-specific products. The VisionXS is especially well suited for mid-range and high-end series production.

Total Cost of Ownership: in search of the actual costs

Against the backdrop of the current economic situation, companies have to think about where cost savings are possible when procuring manufacturing equipment. Rehm’s total cost of ownership program provides solutions to these challenges. It’s targeted at helping companies to reduce their operating costs in a lasting fashion, and to maximize profitability.

Advantages of the total cost of ownership program:

  • Reduced operating costs
  • Improved plant efficiency and minimized downtime
  • Control over the costs and the performance of your reflow system
  • Budget control

We’re aware of the fact that your considerations go above and beyond one-time procurement costs when investing in a machine. Which daily operating costs have to be taken into consideration? How can the consumption of resources be reduced to the greatest possible extent in production? How often is maintenance necessary?

With systems from Rehm, production can be made highly efficient. Our systems are equipped with numerous features such as optimized insulation, best possible heating and cooling performance and a standby mode, all of which go easy on your pocketbook and the environment in a lasting and sustainable fashion. For example, with effective heat recovery you can use waste heat from you production line for in-house hot water supply, cooling regulation and heating support. Our after-sales employees would be happy to provide you with advice on other ways of achieving energy-efficient production with our systems.

Minimal maintenance costs

The design of our reflow systems is extremely compact and consistently planned out – all the way down to the smallest of details. We use sustainable materials and components with a long service life in order to ensure smooth production at you facility. As a result, our systems are very easy to maintain and their operating costs are kept at reasonable levels. Your production line runs smoothly with only minimal downtime and interference. We make sure that your system runs reliably – even when subjected to extreme loads. Our service technicians are at your disposal for routine maintenance of the machine or its individual components, for example the pyrolysis units.

Only as much as actually necessary: controlled nitrogen regulation

Nitrogen offers an ideal process atmosphere for the soldering process. As an inert gas, it doesn’t chemically interact with other substances. Oxidation, corrosion and undesirable influences on the material are prevented.

We offer numerous features for energy-efficient manufacturing. For example, by measuring residual oxygen in the process chamber at regular intervals, you can precisely control the working atmosphere and consistently maintain the desired ppm level. As a result, only as much gas as is actually needed is fed to the process, thus making it possible to reduce nitrogen consumption. Nitrogen control is advisable for flexible SMD production lines with variable loading scenarios and conveyor widths.

Smallest possible ΔT – optimized heat transfer

Heat transfer has been significantly optimized for the VisionXS through the use of 2, 3 or 4 peak zones. Minimal distance between the nozzle sheets and the conveyor, as well as separately adjustable flow rates for the upper and lower heat zones, assure that the PCBs are heated up in an extremely uniform fashion. Stressing within the PCBs is thus minimized and related soldering defects are reduced

A stable conveyor system reduces maintenance and downtime

Our flexible system saves you money. Thanks to a continuous process based on absolutely reliable conveyance, and by locating the mechanical system outside of the process chamber, contamination is minimized and maintenance and downtime are reduced. The conveyor system has been laid out in accordance with requirements specified for future placement machines and optionally for a maximum width of 508 mm.

The optionally available center support makes it possible to process large panel formats. An additional advantage for flexible manufacturing!

Various conveyor options are available depending on system configuration:

  • Single-lane conveyor
  • Two-lane conveyor (synchronous, asynchronous)
  • Four-lane conveyor
  • Multi-track conveyor

A great advantage for your manufacturing process

  • Reliable, disturbance-free production thanks to absolutely parallel conveyance
  • Highly accurate adjustment of conveyor width with good repetition accuracy
  • No influence on the temperature profile caused by the conveyor or the center support
  • Maintenance is minimized by keeping the mechanical system outside of the process chamber
  • Ideal for any application thanks to variable conveyor systems
  • Outstanding process reliability assured by integrated center support

Maintenance just once a year? Pyrolysis makes it possible!

Substances are released from the PCBs, the solder paste and the components during production with modern SMT manufacturing lines, and these can lead to contamination of the soldering system and must therefore be filtered out of the process gas. Modern ovens with nitrogen atmosphere are equipped with so-called residue management systems which recirculate process gas within the system and purify it.

The residue management system included with the VisionXS combines pyrolysis in the preheating and peak zones with cold condensation in the cooling zone. In this way, both liquid residues (in particular the formation of droplets) and crystalline residues can be drastically reduced.

Pyrolysis is laid out so that cleaning is only required once a year – this results in long maintenance cycles and a clean, dry process chamber.

Efficient cracking at 500 °C

Stress-free to below 50 °C

Depending on system type, the VisionXP is equipped with a 2, 3 or 4-stage cooling tract. The fans in the individual zones, which can be controlled separately as an option, allow for accurate control and cooling gradients can be correspondingly influenced. This assure stress-free cooling for your PCBs to below 50 °C, for lead-free soldering as well.

Clever, foolproof software: extremely easy operating concepts

Our software solutions assure precise retraceability of all processes. The Visu 2 includes process and product traceability tools, remote maintenance and a comprehensive product library. It features an intuitive user interface which considerably reduces the effort required for setup and operator training. Complete documentation can be accessed with just a few clicks. The Visu 2 also provides password-protected administration with several access levels, language selection, data logging and maintenance reports.

Process and product traceability is handled by means of barcode management and logging of all relevant process parameters with time stamp.

RPI – Reflow Process Inspection

RPI – Reflow Process Inspection

Reflow process inspection (RPI) supplies continuous information indicating to what extent the reflow profile complies with the specified requirements. It also offers support in creating the ideal profile based on available specifications for solder pastes and reflow ovens, and makes it possible to create one’s own solder joint and component specifications as well.
