Laserline's main topics at Coiltech 2025 from March 26 to 27 in Augsburg will be the contacting of copper wire windings in electric motors, the additive manufacturing of electronic components and the recycling-oriented separation of soldered joints. The industrial laser specialist will also be providing information on the wide range of options for copper material processing using blue diode lasers.
Stripping and contact welding
For electrical contacting - for example of electric motor coils - Laserline will be presenting system solutions for preparatory stripping in the joining area (wire stripping) and subsequent laser welding of the contacts (wire/poles connection). Both solutions are based on blue diode lasers with a wavelength of around 445 nm and are supported by high-precision beam shaping optics.
Additive manufacturing of copper-based electronic components
With a beam quality of ≤ 4 mm∙mrad and output powers of 400 and 800 watts, the new blue high-brilliance lasers LDFblue 400-wbc and LDFblue 800-wbc with WBC technology enable the additive manufacturing of copper-based electronic components using laser powder bed fusion in robust and spatter-free processes. They combine high beam quality with a robust system architecture.
Recycling-oriented separation of solder joints
With blue diode lasers in combination with flexibly adjustable OTZ zoom optics, Laserline will also be showing system configurations for the heat-based separation of soldered copper connections, as can be used for the recycling of copper busbars or other copper-based electronic components.
