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.
Selective laser machining allows for the removal of metalic layers and coatings with little or no machining of the underlying substrate. Very fine lines can be written to create high density circuitry and decorative patterns.
Laser micromilling is applied to create features in flat or contoured surfaces. Beam scanning, mask imaging or a combination of the two provides great flexibility in the range of features that may be produced.
