I kēia pule, ua hāʻawi ʻo Yunboshi i kahi keʻena maloʻo kila kila no ka hui SMT (semiconductor mounting technology). Ma ke ʻano he alakaʻi hoʻopihapiha chip home a me ka ʻoihana hoʻāʻo, hoʻokūkū a nani hoʻi kā lākou huahana i ka ʻoihana semiconductor. Eia nō naʻe, ma muli o kekahi mau pilikia a me nā pilikia i ka mālama ʻana i ka wafer, ʻo nā wafers i hana ʻia e lākou he koi kiʻekiʻe loa no ka mālama ʻana. Hiki i nā loli iki ke hōʻino i nā wafers, a ua maʻalahi nā wafers i ka oxidized a me ka haumia. No laila, pono lākou e mālama ʻia i loko o kahi wahi ʻole o ka oxygen a me ka lepo ʻole. ʻO ke Keʻena maloʻo kila kila no nā ʻoihana SMT. Hāʻawi ʻo Yunboshi i kahi hoʻomalu wela a me ka haʻahaʻa kūpono a me ka hopena anti-oxidation no ke keʻena nitrogen. Mālama ka waihona nitrogen i nā wafers mai ka oxidation a me ka pollution ma o ka hāʻawi ʻana i kahi wahi mālama mālama ʻole o ka oxygen a me ka lepo ʻole, e hōʻoia ana i ka paʻa a me ka hilinaʻi o nā wafers i ka wā e waiho ai.
