Laser induced direct joining of metal to thermoplastics


reinforced materials. Te laser can be used in nearly any production step, including cutting, perforation, ablation, gluing preparation, and marking. Te first step in the production of fibre


reinforced polymer parts is cutting the semi- finished product, using a solid state-laser and a laser remote-scanner for beam movement. Tis ensures rapid and precise cutting. www.trumpf-laser.com

Product traceability of PCB1 electronic and medical devices with mini DPSS lasers


Alexander Jäckl, Innolas Photonics Annett Klotzbach, Fraunhofer IWS Dresden


In the field of lightweight construction, load- capable mixing compounds with the specific material advantages of metal and thermoplastic are increasingly significant. For this, efficient process chains, including adapted pre-treatment and joining processes in combination with process simulation tools, are required. Te presentation will introduce thermally induced direct joining of metal and thermoplastics. It will be shown that an optimised surface pre-treatment enables joints with lap shear strengths of 25MPa and more, depending on the material configuration. By optimising the heat transfer into the metallic section by laser pre-heating, the processing time can be reduced to seconds. www.iws.fraunhofer.de

3D laser processing of fibre- reinforced plastics


Marc Kirchhoff, Trumpf Laser- und Systemtechnik


Fibre reinforced materials are becoming increasingly important in the automotive industry. Terefore, new techniques are needed for processing these materials. Te laser, with its high productivity and precision, could be the right tool for processing these materials, such as carbon fibre reinforced polymers (CFRPs), glass fibre reinforced polymers (GFRPs) or other fibre

marking. Innolas Photonics’ compact Air Mark laser marking modules act as a perfect upgrade for production equipment. Te all-in-one design not only contains the laser and all necessary electronics, but also a beam expander, scanner, pointing laser and scan lens within a small, air-cooled housing. Air Mark laser marking modules provide up to 16W at 1,064nm, 532nm or 355nm, and are controlled by the standard XY2-100 interface. www.innolas-photonics.com

Advances in UV laser micromachining


Scott White, Spectra-Physics


Ultraviolet lasers are increasingly being used in industrial micromachining applications when precision and accuracy are critical. UV lasers can produce very fine and precise features in many materials used in semiconductor, display, microelectronics, printed circuit board, and battery manufacturing industries.


@lasersystemsmag | www.lasersystemseurope.com Production breakthroughs, such as tripling of


silicon machining throughput, have been enabled by increases in UV laser power and repetition rate, shortening of laser pulse widths, and controllability of laser pulse intensity in the time domain. Te presentation highlights some exciting results of high speed and quality precision micromachining, using the latest high power, high repetition rate UV lasers. www.spectra-physics.com

Advanced 3D processing with liquid-jet guided laser


Dr Helgi Diehl, Synova


Te Laser MicroJet technology uses a laser that is guided to the workpiece by means of a high pressure water jet. Tis technique can cut all the same materials as a dry laser, exhibiting a number of additional advantages, like combining high speed parallel kerf machining with a high surface quality. Moreover, being able to cut thick composite


materials with high aspect ratios makes it an optimal customer solution. Synova reports on a new five-axis machine, which enables versatile cutting of PCD/WC tools with a roughness of Ra = 0.2µm and a radius of 5-7µm on the edge. Tis all-in-one solution demonstrates lower roughness than wire cutting, less interface erosion than electrical discharge machining and a higher speed than short pulsed dry laser processing. www.synova.ch

Polygon scanners: capabilities, applications and system integration considerations


Lars Penning, Next Scan Technology


In recent years, high average power for ultrafast pulsed lasers has become available. However, to be competitive in laser micromachining, high throughput is essential to compete with currently established techniques.
