ʻO QFN a me DFN, kēia mau ʻano ʻelua o nā ʻāpana semiconductor ʻāpana, e huikau pinepine i ka hana pono. ʻAʻole maopopo ʻole ʻo wai ka QFN a ʻo wai ka DFN. No laila, pono mākou e hoʻomaopopo i ke ʻano o QFN a me ka DFN.
ʻO QFN kahi ʻano o ka ʻeke. ʻO ia ka inoa i wehewehe ʻia e ka Japan Electronics and Machinery Industries Association, me ka hua mua o kēlā me kēia o nā huaʻōlelo Pelekane ʻekolu i hoʻopaʻa nui ʻia. Ma ka ʻōlelo Pākē, ua kapa ʻia ʻo ia ʻo "square flat no-lead package."
ʻO DFN kahi hoʻonui o QFN, me ka hua mua o kēlā me kēia o nā huaʻōlelo Pelekania ʻekolu i hoʻopaʻa nui ʻia.
Māhele ʻia nā pine o ka pahu QFN ma nā ʻaoʻao ʻehā o ka pūʻolo a ʻo ka hiʻohiʻona holoʻokoʻa he huinahā.
Hoʻokaʻawale ʻia nā pine o ka pahu DFN ma nā ʻaoʻao ʻelua o ka pūʻolo a ʻo ka hiʻohiʻona holoʻokoʻa he rectangular.
No ka hoʻokaʻawale ʻana ma waena o QFN a me DFN, pono ʻoe e noʻonoʻo i ʻelua mau kumu. ʻO ka mua, e nānā inā aia nā pine ma nā ʻaoʻao ʻehā a i ʻole ʻelua ʻaoʻao. Inā aia nā pine ma nā ʻaoʻao ʻehā, ʻo QFN ia; inā ʻelua ʻaoʻao wale nō nā pine, ʻo ia ka DFN. ʻO ka lua, e noʻonoʻo inā he huinahā a ʻehā paha ke ʻano holoʻokoʻa. ʻO ka mea maʻamau, hōʻike ka hiʻohiʻona huinaha i ka QFN, a ʻo ka hiʻohiʻona ʻāʻī e hōʻike ana iā DFN.
