Laser Patterning

”Direct Laser Patterning of coatings such as aluminum on polyimide (Kapton). Rapid removal of large and small areas with feature sizes down to a couple of microns. All that is required to get started for this maskless process is a CAD file.”

Careful choice of laser process parameters allows shallow marking of almost any substrate material or controlled removal of surface coatings with micron precision.

Best results are achieved when the laser wavelength and pulse duration are chosen to provide a strong interaction with the material to be removed. In many cases laser removal and patterning of surface coatings can be a highly selective process if the laser interacts strongly with the coating and only weakly with the underlying substrate.
