I-QFN ne-DFN, lezi zinhlobo ezimbili zokupakishwa kwengxenye ye-semiconductor, zivame ukudideka kalula emsebenzini ongokoqobo.Ngokuvamile akucaci ukuthi iyiphi i-QFN nokuthi iyiphi eyi-DFN.Ngakho-ke, sidinga ukuqonda ukuthi iyini i-QFN nokuthi iyini i-DFN.
I-QFN iwuhlobo lokupakisha.Yigama elichazwe yi-Japan Electronics and Machinery Industries Association, enohlamvu lokuqala lwegama ngalinye kwamathathu esiNgisi anosonhlamvukazi.NgesiShayina, ibizwa ngokuthi "iphakeji eliyisikwele elingenawo umthofu."
I-DFN isandiso se-QFN, enohlamvu lokuqala lwegama ngalinye kwamathathu esiNgisi anosonhlamvukazi.
Izikhonkwane zephakeji ye-QFN zisatshalaliswa kuzo zonke izinhlangothi ezine zephakeji futhi ukubukeka okuphelele kuyisikwele.
Izikhonkwane zephakeji ye-DFN zisatshalaliswa ezinhlangothini ezimbili zephakheji futhi ukubukeka okuphelele kungunxande.
Ukuze uhlukanise phakathi kwe-QFN ne-DFN, udinga kuphela ukucabangela izici ezimbili.Okokuqala, bheka ukuthi izikhonkwane zisezinhlangothini ezine noma izinhlangothi ezimbili.Uma izikhonkwane zikuzo zozine izinhlangothi, yi-QFN;uma izikhonkwane zisezinhlangothini ezimbili kuphela, yi-DFN.Okwesibili, cabanga ukuthi ukubukeka okuphelele kuyisikwele noma kuwunxande.Ngokuvamile, ukubukeka kwesikwele kubonisa i-QFN, kuyilapho ukubukeka kukanxande kubonisa i-DFN.
