Description

VisionXC Convection soldering 

The reliable Reflow Soldering System for your production!

Established since 1990, Rehm company has successfully been a leading position in the European and Global Market for its Extraordinary
Quality Standard and Know-how in design and manufacturing of modern Reflow-Convection-Soldering Systems.
Equipped with our experience, VisionXC is specially designed for the Mid-sized Manufacturer, that can at the same time provide productivity, quality and a well balanced technology with the best price-performance level.

The Transport System

Due to our secure transport system and the arrangement of the transport mechanism outside of the process chamber you receive a stabile process while reducing maintenance expenses and machine downtime. The optionally available centre support
makes it possible to process large panel formats – an additional advantage for flexible manufacturing!

Ideal Heat Transfer

Heat transfer has been significantly optimized for the VisionXC through the use of two, three or four 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.

Stress-free cooling

Depending upon the length of the system, the cooling tract in the VisionXC nitro is laid out in 1- to 4 stages. 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 assures stress-free cooling for your PCBs, for lead-free soldering as well.

 

Residue Management System

Residues which accumulate during soldering are separated by a new Residue Management System included in VisionXC systems. Depending on the system length it is equipped with a 1 up to 3-stage Residue Management System. Each stage consists of a cooling and a filter unit.
With this combination liquid and crystalline residues can be drastically reduced. Out of this you gain the big advantage of a lower rate of maintainance intervals and a higher efficiency in working.
