Coating Removal

Selective removal of one material deposited on top of another material can be successfully performed by using a laser beam. In each particular case, laser wavelength, pulse energy, and the amount of pulses determine conditions, which are efficient for removal of top coating without affecting properties of the base material. Selective material removal allows patterning metal coating on top of polymer, glass and ceramic substrates. It also allows removing polymer coating (like Teflon, PVC, Parylene etc.) from metal surfaces. Coating removal with a laser is more environmentally friendly than other methods like conventional chemical etching. Typical applications include:

Creating electrode patterns
Patterning ITO coating
Removing dielectric cover material to expose electrodes
Machining pockets in a coating for drug-eluting stents
Forming transmissive patterns in optically reflective coatings
Machining day and night knobs for automotive industry
Patterning coating on windshield glass for automotive industry
Removing metal coating from both sides of polymer base film for electronic industry
