Selective laser ablation is applied where individual layers have to be ablated without significantly damaging the layers or substrates below. The ablation geometry can be spot or line shaped or two-dimensional.
Examples can be found in many areas of industrial manufacturing: Laser ablation in photovoltaics, laser ablation in the electronics industry.
Lasers with best beam quality (TEM00) and very high repetition rates of up to 200 kHz are used for the ablation of 20–50 microns wide scribe lines at process speeds of up to 2000 mm/s without damaging the glass substrate or the layers beneath.
For this application we recommend: PowerLine-Series, x-Lase, Roll-to-Roll System, Lab System
Ablation of polymer layers out in a polymer-metal compound for realizing electromagnetic shielded housings. The polymer-conductor-compound is injection molded and then the pre.defined layers is ablated by a CO2 laser. The exposed metal fabrics provide conductive contact to surrounding housing parts.
For this application we recommend: StarShape
