Semunductic yopanga Chuma Chachilengedwe Chachilengedwe Chinalengeza kuti limapeza ndalama kuchokera ku Maboma a Chitchaina. Semisonducnge atapanga Chuma chapadziko lonse lapansi limatulutsa 6,000. Wofers ndiosavuta kutenga kachilomboka. Kukhala wopereka ma seciokiki omwe amapereka, Yunboshi akutsogolera munyezi ndi kutentha kutentha kotheratu kwa zaka zopitilira khumi. Khola louma limagwiritsidwa ntchito kuteteza zinthu ku chinyezi ndi chinyezi chofanizira zowononga monga heewa, bowa, dzimbiri, makoko, oxidation, ogula. Nthawi yotsogola yolowera pamsika ya mphindi zosakwana 3 imapereka nthawi zonse zosungidwa. Yunboshi amayang'ana kwambiri pakufufuza ndikukula kwake chinyezi chowongolera m'misika yambiri mu mankhwala ogulitsa, zamagetsi, semiconductor ndi ma CD.
