Laser metal coating on polymer substrate
Laser micromachining is widely used for patterning thin (thickness less than 0.1um) metal coatings deposited on the surface of thicker polymer substrates. Removal of metal coating is based on photo-thermal absorption of the laser energy and takes place when laser induced tensile pressure wave reaches the metal to polymer interface and tensile force exceeds forces of adhesion.
