I-Laser etching, isetyenziselwa ukukhetha ukunyibilika kunye nokususa ipeyinti kwiindawo ezithile zomgangatho ophezulu. Nje ukuba ipeyinti isusiwe, ukukhanya ngasemva kuya kukhanyisa ikhiphedi kuloo ndawo.

Kubalulekile ukuqaphela ukuba i-keypads yerabha ye-silicone ihlala i-laser-etched ukunyusa imiphumo yokukhanya kwangasemva.I-Laser etching isebenza kuphela, nangona kunjalo, ukuba i-keypad yerabha ye-silicone ine-back-lighting. Ngaphandle kokukhanyisa ngasemva, indawo ene-laser okanye iindawo aziyi kukhanyiswa. Ayizizo zonke iiphedi zerabha ze-silicone ezinokukhanya ngasemva zifakwe ngelaser, kodwa zonke okanye uninzi lwezitshixo zerabha ze-silicone ezifakwe ngelaser zinezikhanyiso zangasemva.
