[SLPC9-04] Experimental Characterization of Shock Wave Expansion in Innovative Nanosecond Laser Ablation Process Enabling Repair and Recycling

*Dominic Heunoske1, Martin Lueck1, Jens Osterholz1 (1. Fraunhofer EMI)

In the Rapid-KI project a new process is developed to control laser ablation for repairing or recycling electronic components that are protected by a coating. Therefore experimental data obtained from nanosecond single pulse experiemnts was used to calibrate a simulation model of laser ablation. The expansion of the shock wave was determined using a schlieren imaging system and the Sedov-Taylor theory.
