Page 35 Rehm Enables Fine Control of Reflow Cooling


ROSWELL, GA — With the VisionXP+ con- vection soldering system from Rehm Ther- mal Systems, the soldering process does not end with the melting of the solder. For an op- timal soldering result, a stable and reliable cooling process is particularly important, which can be flexibly designed with this type of system. In addition to standard cooling with


four cooling modules, customers can also choose an extended cooling section (power cooling unit), underside cooling or an ener- gy-saving cooling variant. With Rehm CoolFlow, Rehm also of-


fers an innovative cooling system using liq- uid nitrogen. The standard cooling system installed in all Vision convection soldering systems consists of up to four in- dividual cooling modules. These allow a precisely controlled cool- ing process as well as individual adjustment of the cooling gradi- ent.


For the cooling process, a


small part of the warm and charged air volume present due to the soldering process is first ex- tracted into the lower part of the system. It is then cleaned over sev- eral cooling modules and cooled to

the desired temperature. The air is then blown back from above


onto the assembly to cool it. The closed-loop de- sign guarantees an isolated atmosphere cycle.


The standard cooling section consists of active and passive cooling modules. The active cool- ing modules are supplied with water via a heat exchanger. For gentle cooling, especially for com-


plex assemblies, an extended cooling sec- tion can be connected to the VisionXP+. This can be implemented as an exten-


sion to standard cooling zones under a ni- trogen atmosphere or as a separate, down- stream module in an air atmosphere for higher cooling performance for insensitive materials. Contact: Rehm Thermal Systems,
