Laser Cleaning of Polypropylene Contamination on Magnetic Head Slider Surface

Abstract:

This work aims to obtain the well-implemented laser cleaning to remove polypropylene (PP) contamination of sizes ragne 10-60 µm on magnetic head slider by excimer laser at 248 nm. The finite element: FEM [1] simulations shows non-destructive cleaning at laser fluence of 100mJ/cm². The experiment shows that laser fluence is non-destructive at 70mJ/cm² and can remove 15-40% of polypropylene (PP) contamination.
