| The advantages of laser driiJiDg of ceramics are that boles can be
accurately positioned with higher precision as compared to conventional
methods. A continuous wave C01 laser is used to driB holes in
sintered alumina substrates. The mic:rostrnctures have been stnclied,
using a scanning electron microscope. The morphology of the hole
formed has been studied near the aftected zones, both radially and
axially. |
