QFN ne-DFN, lezi zinhlobo ezimbili zokufakwa kwengxenye ye-semiconductor, zivame ukudideka kalula emsebenzini osebenzayo. Ngokuvamile kungacaci ukuthi iyiphi i-qfn futhi iyiphi i-DFN. Ngakho-ke, kudingeka siqonde ukuthi yiliphi i-QFN nokuthi yini i-DFN.
QFN uhlobo lokupakisha. Yigama elichazwa yiJapan Electronics kanye nemishini Association, ngencwadi yokuqala yawo nalawo magama amathathu esiNgisi akhishwe. NgesiShayina, ibizwa ngokuthi "iphakethe lesikwele elingenamkhawulo."
I-DFN isandiso se-QFN, ngencwadi yokuqala yawo nalawo magama amathathu esiNgisi akhishwe.
Izikhonkwane zokupakishwa ze-QFN zisatshalaliswa kuzo zonke izinhlangothi ezine zephakeji nokubukeka okuphelele kuyisikwele.
Izikhonkwane zokupakishwa kwe-DFN zisatshalaliswa ezinhlangothini ezimbili zephakeji nokubukeka okuphelele kungunxande.
Ukuhlukanisa phakathi kwe-QFN ne-DFN, udinga kuphela ukubheka izinto ezimbili. Okokuqala, bheka ukuthi izikhonkwane zisezinhlangothini ezine noma ezinhlangothini ezimbili. Uma izikhonkwane zikuzo zonke izinhlangothi ezine, yi-qfn; Uma izikhonkwane zisezinhlangothini ezimbili kuphela, i-DFN. Okwesibili, cabanga ukuthi ukubukeka okuphelele kuyisikwele noma unxande. Ngokuvamile, ukubukeka kwesikwele kukhombisa i-QFN, ngenkathi ukubukeka okungunxande kukhombisa i-DFN.
