Vacuum und protective gas soldering

Technology for Vacuum Soldering / Brazing

Pocess steps:

• Loading, evacuating, heating, soldering, forced cooling and ready for a new use after in 4 hours
• Separate Data recording for each process run
• High availability
• Best quality results coming from temperature homogeneity ± 3 K
• Final vacuum better than 5x10-6 mbar
• Accelerated processing with forced cooling at the process end
• Cooling system on board (no cooling water installation)
