Laser  Scribing makes possible the cost effective manufacture of arrays (multiple ceramic parts) that may be then singulated by breaking them apart. Scribing also provides a cost effective means of improving part quality by allowing the removal of the outside borders that contain defects such as rough or non-parallel edges.

A laser scribe line consists of a series of small, closely spaced holes in the substrate that are produced by pulses of laser energy. Viewed under magnification, the scribe holes should appear essentially clean and free of recast. under backlighting a plugged hole will appear dark. An occasional plugged hole will not affect the scribe.
