Multi Vacuum
The Multi Vacuum soldering process is essential for the quality for modern applications. In the Multi Vacuum soldering process, an assembly can be subjected to several vacuum applications during one soldering process. The Multi Vacuum process offers the possibility of carrying out vacuum processes both before and during the melting of the solder paste.
Benefits of Multi Vacuum for your assembly
Higher mechanical stability
Increased lifetime of the assembly
Improved heat removal (power electronics)
Reduced signal interference (high frequency technology)
Cost savings. Since the performance of the individual component is higher due to the void reduction, fewer components are required for the overall performance of the assembly.

- Useful supplement to the vapor phase soldering process for high quality requirements.
- Due to the arrangement of the vacuum chamber outside the hot process zone (Clean Vacuum), reduced maintenance work as well as longer maintenance cycles are guaranteed
