Kubata Chengetedzo: Chishandiso ichi chinogona kukuvara semhedzisiro ye electrostatic discharge (ESD).
A static free environment inokurudzirwa zvikuru.Tevedzera nhungamiro zvinoenderana nekwakakodzera ESD maitiro.
Laser Kuchengeteka: Radiation inoburitswa nelaser zvishandiso inogona kuve nengozi kumaziso evanhu.Dzivisa kuratidzwa kweziso kune yakananga kana isina kunanga mwaranzi.
