In industrial and power electronics, 95% of all modules use mixed-mode assembly. We integrate HEEB laser-guided assembly tables into partial linear production.

Part preparation – involving the bending, cutting, beading and programming of all types of IC components – is completed directly within the unit.

A transponder system ensures that modules can be identified at any time and at any point within the production process.
