Summary
A dual-wavelength laser platform (combined 532nm and 1064nm wavelengths) for welding copper and aluminium for electrical connections in solar cell and battery applications, using fixed and scanning optics.
Innovation: Single laser source capable to deliver Green and IR wavelength at the same time. Proportion of Green and IR radiation is set online via pulse shaping.
Customers target:
- Electronics industry (Ribbon and wire bonding).
- Solar industry (thin film bonding).
Benefits:
- More reliable and reproducible copper welding process.
- Higher yield, less pre-processing costs.
