As part of a joint project, SEHO is currently working with CERN on a prototype system for a key process step in the production of non-insulated coils made from high-temperature superconductors. These superconductors are considered as a key technology for high-performance, highly compact magnetic coils that will enable unprecedented magnetic field strengths in future particle accelerators, while also increasing efficiency.
The project is part of the MuCol (Muon Collider) program coordinated by CERN and thus makes an important contribution to the development of the next generation of accelerator technologies.

A breakthrough for a process step that was previously impossible to monitor

The application of flux in wave and selective soldering is a key process step, but one that has been difficult to control until now. Too little flux leads to soldering errors such as incomplete penetration or cold solder joints, while too much can cause residues that can impair the function of the assembly.
Previous monitoring methods are generally based on random sampling or purely functional checks of the fluxer. They therefore do not provide any information about the actual application on the individual printed circuit board.
