The project focuses on ICT for agile and environmentally friendly manufacturing. The advanced level of automation that the fully integrated (laser) welding station will offer, will allow the approach not only for mainstream high-volume manufacture, but also for small-series production. The application of the laser scanner, for instance, allows fast, versatile programming of laser paths, which can be altered for each product, if necessary. The dual-wavelength nature of the scanner will facilitate a fast change-over between the welding of copper and aluminium interconnections. Smallscale manufacturing (and to some extent large-scale manufacturing) requires traceability of products, through its production life and its in-serve lifecycle. Using the same laser source for marking will facilitate this aspect of small-series production.
