Laser Scribing & Patterning

Laser scribing is well suited to the creation of fine lines and other blind features and patterns. Laser energy can be applied to the material in one of two ways, either focused to a small spot and scanned over the surface or imaged through a mask to project the pattern onto the surface. The use of laser scribing allows for very accurate writing of fine features both in the surface of a material and by the selective removal of one or more layers in a multi-layer substrate.

demetaltrack4Thin oxide layers on flexible and rigid materials may be be patterned to determine conductive and non-conductive areas.
