Standard Laser Tolerances

GENERAL GUIDELINES

  • Typical Scribe Depth: 40% - 50% of Substrate Thickness
  • Typical Pulse Spacing: .005" +.002"/-.001"
  • Standard Dimensional Tolerance (after snapping): .002"
  • Standard Tolerance for "Slag": <.002"

NOTE: All holes are measured on the laser exit side of the material either optically or with pin gauges.

All tolerances are specified in inches and on 91% to 99.9% Alumina.
All dimensions and tolerances are LPT standards. Consult with LPT when more stringent tolerances are required.
