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 he aha 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.
