Vision XP+
We take all relevant parameters into consideration in the process of this. Take for example the throughput rate, this is one of the most important parameters for determining the optimum process zone length. If frequent product changes and multi-shift operation are added to the equation, additional options will be required that need also be taken into account. After clarifying all the process-relevant parameters, you can rest assured that you will have a reflow soldering system adapted to all your needs, one with which you can manufacture reliably and efficiently. The diverse range of options within the Vision range means that we have the right system for every manufacturing environment.
The convection soldering systems in the Vision series are available in different lengths and with different transport options. This modular system concept provides a huge amount of flexibility in the production process. Thanks to the flexible transport system, the VisionXS can be set up on an individual basis in accordance with the requirements in terms of the transport tracks and the transport speed. The integrated cold condensation option guarantees you simple cleaning and maintenance of the system thanks to the ease of changing the cooling filter on the reverse side of the system. The maintenance of the system is made even more user-friendly thanks to the use of sustainable materials and durable components. With the Power Cooling Unit, the assemblies can be cooled in a manner that is as gentle as possible in a multistage cooling process in a stable atmosphere.
The VisionXP+ is our “best in class” reflow convection soldering system, which is clearly in line with the trend towards the sustainable management of resources. With a particular focus on energy efficiency, reducing emissions and operating costs, EC motors were integrated into the VisionXP+ and these enable you to save on energy in a provable manner. The option of carrying out vacuum soldering enables you to create a time-efficient and stable production procedure, as well as to reduce voids, in order to ensure low-maintenance manufacturing. With the VisionXP+, you have various options available to you for gentle cooling, including underside cooling. With this, especially high-mass boards in particular can be cooled easily.
Vacuum chamber
With the VisionXP+. we offer innovative solutions for reflow soldering. In just one process, a vacuum module enables convection soldering processes to be carried out with a vacuum.
This reliably removes pores, gas occlusions and voids immediately after the soldering process whilst the solder is still in its optimal molten state. Complex processing of the assembly via an external vacuum system is no longer necessary and the workpieces are moved straight into the vacuum process from the peak zones.
Rehm Cool Flow
In cooperation with Air Liquide, we developed an innovative cooling principle for more efficient use of the nitrogen required for inertisation and built the first reflow soldering system without any cooling water with a nitrogen cooling system. The cryogenic liquid nitrogen (as cold as –196°C) provides its cooling properties inside the system’s cooling zone, evaporates and can then be used for inertisation in its gaseous state. This means that the system is provided both with the required cooling properties and the inert atmosphere. The cooling water, which previously required high energy use for cooling, including cooling unit and refrigerant, is completely eliminated.
Pyrolysis
During the soldering process, substances that are released from circuit boards, solder paste or components must be filtered out of the process gas. This is why the VisionXP+ has a residue management system which recycles and cleans the process gas in the system. It combines the effect mechanisms of pyrolysis in the preheating and peak range with cold condensation in the cooling zone. The pyrolysis is set up so that it only needs to be cleaned once a year, which results in long maintenance cycles, as well as a clean and dry process chamber.
SSP+
In comparison with the SSP, the SSP+ is characterised by a further setting option at high temperature differences between the individual heating zones. Since from a zone with a high temperature, this temperature is transferred to the neighbouring zone, it may be necessary to actively cool this zone on an ongoing basis in order to ensure the right temperature profile. The in-house extraction system permanently draws in the colder surrounding air and thus ensures precise temperature resistance in the respective zone. The heat which is transferred from neighbouring zones is reduced drastically like this, which ensures optimum zone division.
