Zida zowongolera mafakitale nthawi zambiri zimakhala ndi anti-magnetic, anti-fumbi, anti-shock ndi zina zotero, ndipo zimakhala ndi mawonekedwe a mbale yapadera, mphamvu zotsutsana ndi kusokoneza mphamvu, mphamvu zogwira ntchito nthawi yayitali ndi zina zotero.Pakalipano, China yazindikira makina a chitukuko cha mafakitale, zomangamanga za 5G zimalimbikitsa chitukuko cha malo otsika pansi ndi matekinoloje monga intaneti ya zinthu, ndikufulumizitsa kukhazikitsidwa kwa mafakitale.

Zogulitsa zamagetsi zamagetsi monga gawo lofunikira la makina opanga mafakitale, zikuyenera kupanga chitukuko mwachangu pamsika womwe ukukulawu.Ndi chitukuko cha makina owongolera mafakitale, zida zamagetsi zamagetsi zamagetsi zikuchulukirachulukira, zomwe zimabweretsa kufunikira kwa zida zamagetsi zakumtunda za PCB.

Kufunika kwa msika kwa PCB pankhani yoyang'anira mafakitale ndi zida zamankhwala kukuchulukirachulukira, ndipo opanga ma PCB ambiri amafufuza mwachangu ndikutumiza maloboti akumafakitale ndi zida zamankhwala zapamwamba.
