Most versatile multi plate vacuum soldering systems

The centrotherm c.VACUNITE 300 and 180 multi plate vacuum soldering systems are designed for thermal vacuum-based processing of various materials in high-volume production. The systems meet highest requirements of ultra-clean voidless soldering for advanced packaging and power semiconductor applications. With c.VACUNITE 300A, which is equipped with an automated door closure centrotherm provides an excellent solution for fully automated production lines.

Depending on the field of application the systems ensure fast heat-up and cool-down rates for short cycle times and large processed area per hour while reaching temperatures up to 650 °C.

c.VACUNITE systems allow processes under pure and oxygen-free atmospheres and provide surface activation with 100% hydrogen (H2), formic acid (HCOOH) or forming gas (N2H2).

The void-affected area can be reduced to less than 1% whereas common reflow soldering systems range at 5%.

The process control computer is equipped with a 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.
