Vacuum soldering systems for R&D and pilot scale production

The centrotherm c.VACUNITE contact heat system platform covers a wide range of thermal vacuum applications. The versions 24, 12 and 6 are designed for process performance-based R&D and pilot scale production. In the field of vacuum soldering the systems meet highest requirements of voidless soldering for Advanced Packaging and Power Semiconductor applications. The void-affected area can be reduced to less than 1% whereas common reflow soldering systems range at 5%.

c.VACUNITE systems ensure fast heat-up and cool-down rates for short cycle times and reach temperatures up to 450 °C.

c.VACUNITE vacuum soldering systems allow processes under pure and oxygen-free atmospheres and provide surface activation with 100% hydrogen (H2), formic acid (HCOOH), forming gas (N2H2) and/or additional MW plasma. All systems are suited for 100% paste and flux.

The process control computer is equipped with an user-friendly touch screen for operating, process profile editing and recipe storing. Accessibility through Ethernet and USB interfaces allows connection with printers, external storage devices and remote access.
