A patented vacuum chamber within the process chamber ensures process reliability and void-free soldering results, as both the number and size of voids are minimized. The system can be fully integrated into a production line and operated in batch mode if required.

Three variants - maximum flexibility with minimum space requirements

The customer can choose between three machine types with different carrier sizes. Both variants:

  • work with a integrated vacuum system
  • are for inline and batch operation designed
  • only need small footprint

Thanks to the unique vapour phase technology, the machines in the VAC Inline series guarantee excellent soldering results with high reproducibility. Circuit boards with different numbers of layers and an extensive mix of components can be reliably soldered with the vacuum soldering systems. Thanks to the "Intelligent Profiling System", the user has full control over the temperature rise. This allows outstanding soldering profiles to be achieved with pinpoint accuracy.

With the soft vapour phase control an unnecessary rise in temperature is avoided. This means:

  • less component stress
  • lower energy consumption
  • lower operating costs

Further advantages:

  • excellent heat transfer in a inert, oxygen-free atmosphere
  • no need for expensive nitrogen
  • user-friendly two-chamber system with large touch display
  • identical profile for all assembly weights usable

The systems in the VAC Inline series are available in three different configurations. All systems are designed for inline vapour phase soldering under vacuum. The customer can choose between three models depending on the workload. Compared to the VAC745i and VAC765i, the machine model VAC745HDxi works simultaneously with 2 workpiece carriers, which increases the throughput by up to 70 % compared to the VAC745i and VAC765i.

In addition, the soldering:

  • independent of weight possible with the same profile in one system
  • both for lead-free as well as lead-containing processes suitable with only one medium

Product highlights

  • patented vacuum chamber inside the process chamber
  • highest precision and process quality with patented Soft Vapour Temperature Control (SVTC)
  • integrated PC enables permanent data acquisition and professional data management
  • create a high-end soldering profile in just a few steps with the Intelligent Profiling System (IPS)

Further added value

  • convenient 15″ touch screen, mounted on a swivel arm
  • live temperature recording via IBL machine software
  • traceability and documentation via IBL machine software, optionally with barcode function
  • unlimited program memory with many sample programs
  • network-compatible
  • password-protected operating levels
  • buffer in the loading and unloading area and automatic loading and unloading of the workpiece carrier
  • flexible vacuum parameters, system and multi-vacuum possible
  • heat output monitoring
  • energy management system
  • lead-free and leaded soldering with only one medium with different soldering temperatures
  • two chamber design with medium recovery and integrated heat exchanger result in very low liquid consumption
  • fill level control and automatic medium filtering
  • patented rapid cooling system (RCS) for sensitive components
  • integrated cooling fan
  • 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
  • signal light
  • connection for a suction unit
