Kodi nduna youma ndi iti? Ntchito yake ndi chiyani? Khothi louma ndi makina amagetsi omwe amapangidwira kuti athe kuyanika kwa zinthu. Sungani nyumba youma imapereka zosungidwa za zinthu zamagetsi zamagetsi, mapiritsi, mankhwala mu ufa, zimatanthauzira, zida zamatabwa. Muyezo wa nduna umatha kuwunika kutentha komwe kumafunikira komanso chinyezi.Chida cha Matanda S ndiosavuta chotenga kachilombo ka chinyezi. Awo amachita nthawi yayitali ngati akasungidwa chinyezi chokwanira. Zida zamatabwa zikufunika kusungidwa pamalo okhazikika 45-55% rh.

Popeza anali kupereka chinyezi / kutentha kwa ma semiconductor ndi zipsera kwa zaka zopitilira khumi, Yunboshi amatsogolera chinyezi komanso kutentha ku China. Kutumikira makasitomala ake kwa zaka zopitilira 10, Yunboshi yamagetsi amalandila malamulo abwino kuchokera kwa makasitomala ochokera ku America, Asia, makasitomala aku Europe. Chinyezi / kutentha kwa kutentha ndi makabati ogulitsira amagulitsidwa msika wachi China komanso wapadziko lonse lapansi. Zogulitsa zimagwiritsidwa ntchito kwambiri kunyumba ndi mafakitale, mwachitsanzo, mankhwala, labotactory, semiconductor, lcd ndi mafakitale ena ndi mapulogalamu ena.
