High-Precision Laser Welding of Transparent Plastic
LPKF paper at the Laser Manufacturing Conference available as a TechPaper
Complex systems with channel cross-sections in the micrometer range are used for fast analysis in a number of fields including food safety, clinical diagnosis, chemical synthesis and biological research.
The high-precision mechanical and optical positioning system in the LPKF PrecisionWeld uses the welding properties of transparent plastics at a laser wavelength of 2 μm. This creates an effective technology for the prototyping and series production of microfluidic components.
The TechPaper describes the technical principles, the design implementation as a laser welding system, and the resulting welding parameters which can then be achieved. The TechPaper can be downloaded free-of-charge on the LPKF website in the Knowledge Center (www.lpkf.com/knowledge-center).
