Flux-free vacuum soldering

vacuum soldering

Flux-free vacuum soldering with preforms is very unique compared to conventional soldering techniques with paste. A set of completely different parameters must be considered for the development of soldering profiles. As the removal of contaminations is severely limited at flux-free soldering, the material quality of the components is crucial. Mostly, formic acid, hydrogen, forming gas or plasma is used to reduce surface oxides.

We offer advanced vacuum soldering training courses, which will enable engineers to develop more robust soldering processes in a shorter amount of time.

Possible training and project contents:

  • Development of flux-free soldering profiles
  • Typical faults that arise during soldering and temperature profiling
  • Temperature measurement techniques and sources of errors
  • Influence of previous processes on the paste-free soldering
  • Material quality check, soldering jigs and fixtures, as well as systems with rapid testing functions
  • Identification of save process windows
  • Transfer of laboratory processes to mass production
  • Introduction of inline measurements and statistical process control
seminars for data science
