Photo Etching: Tolerances


Photo etching tolerances in millimeters or as a percentage of material thickness. Please note that tolerances may be improved upon with development, and are subject to feature geometry, material type and sheet size.


For greater chemical etching tolerances see Laser Evolved Etching Process
