Laser etching, imagwiritsidwa ntchito posankha kusungunula ndikuchotsa utoto kumadera ena apamwamba. Utotowo ukachotsedwa, kuyatsa kumbuyo kudzawunikira makiyi m'derali.

Ndikofunika kuzindikira kuti makiyipilo a mphira a silikoni nthawi zambiri amakhala opangidwa ndi laser kuti awonjezere kuyatsa kwapambuyo.Kuyika kwa laser kumangogwira ntchito, komabe, ngati kiyibodi ya mphira ya silikoni ili ndi zowunikira kumbuyo. Popanda kuyatsa kumbuyo, malo okhala ndi laser kapena malo sangawunitsidwe. Sikuti makiyipilo onse a mphira a silikoni okhala ndi zounikira kumbuyo amakhala ndi laser, koma makiyipilo a rabara onse kapena ambiri amakhala ndi zowunikira kumbuyo.
