Soldering Technology

Plants and systems for void-free soldering with vacuum

Vacuum soldering for high-quality production

The power density of advanced electronic components like e.g. power modules, hybrid and multichip components, etc. is continuously growing. Therefore, the quality of solder connections must fulfill the increasing demands as well. Gas inclusions (= voids) in the solder connections must be avoided.

The best way to remove such from the liquid solder is the systematic use of vacuum during the soldering process.

The vacuum soldering systems by PINK provide void-free solder connections, e.g. of large power modules, with preform solders and / or pastes in a continuous process.
