Thanks to the in-vapour technology vacuum process integrated in the process chamber, voids can be avoided during the soldering process. This enables void-free soldering. The innovative technology of the VAC series therefore guarantees void-free soldering results.

Vacuum soldering with precision and process reliability

Thanks to the unique system architecture, the VAC745 and VAC765 are particularly suitable for vacuum soldering demanding components such as BGAs, where quality and precision are crucial. The patented technology of these machines ensures outstanding results in terms of performance and quality. The system copes with:

  • most complex assembly structures
  • regardless of the number of layers in the circuit board
  • even with a high component mix

The machine concept is therefore particularly suitable for automated vacuum soldering in series production.

The "Intelligent Profiling System (IPS)" enables the user:

  • full control over the temperature rise,
  • precise creation of optimum soldering profiles,
  • and thus a high reproducibility of the soldering processes.

This precise control is a key success factor for efficient vacuum soldering processes.

In combination with the patented "Soft Vapour Phase" will:

  • reliably prevents an excessive temperature increase of the components
  • material stress significantly reduced
  • and thus sustainably increases the reliability of the soldering process.

The system guarantees consistent soldering results regardless of the weight of the assembly.

Compared to other vacuum reflow ovens, the VAC series is impressive:

  • exceptionally low energy consumption
  • lower operating costs
  • excellent heat transfer in an inert, oxygen-free atmosphere, without the use of expensive nitrogen.
  • two-chamber system with large touch display enables
  • intuitive and user-friendly vacuum soldering.

This ensures efficient vacuum soldering at the highest level.

Product highlights

  • patented vacuum chamber inside the process chamber
  • maintenance-free transport system (patented)
  • low medium consumption due to 2-chamber design and medium recovery
  • automatic monitoring of the vacuum pressure
  • controllable vacuum generation in stages, multi-vacuum or linear mode

Further added value

  • intelligent Profiling System (IPS) for controlling the thermal profile in the high-end range
  • convenient 15″ touch screen
  • integrated PC enables permanent data acquisition and professional data management
  • unlimited program memory with many sample programs
  • network-compatible
  • password-protected operating levels
  • energy management system
  • heat output monitoring
  • automatic infeed and outfeed of the workpiece carrier
  • medium level control and automatic filtering
  • minimal maintenance and low wear, as all moving parts are outside the process chamber
  • easy access to the soldering chamber for cleaning and maintenance purposes
  • viewing window into the illuminated soldering chamber
  • connection for a suction unit
