I-QFN kanye ne-DFN, lezi zinhlobo ezimbili zokupakisha izingxenye ze-semiconductor, zivame ukudideka kalula emsebenzini osebenzayo. Ngokuvamile akucaci ukuthi iyiphi eyi-QFN nokuthi iyiphi eyi-DFN. Ngakho-ke, sidinga ukuqonda ukuthi iyini i-QFN nokuthi iyini i-DFN.
I-QFN uhlobo lokupakisha. Yigama elichazwa yi-Japan Electronics and Machinery Industries Association, kanti uhlamvu lokuqala lwamagama amathathu esiNgisi lubhalwe ngosonhlamvukazi. NgesiShayina, libizwa ngokuthi "iphakethe lesikwele elingashayi eceleni."
I-DFN iyisandiso se-QFN, kanti uhlamvu lokuqala lwamagama amathathu esiNgisi lubhalwe ngosonhlamvukazi.
Izikhonkwane zephakheji ye-QFN zisakazwa kuzo zonke izinhlangothi ezine zephakheji futhi ukubukeka kwayo konke kuyisikwele.
Izikhonkwane zokupakisha ze-DFN zisakazwa ezinhlangothini ezimbili zephakheji futhi ukubukeka kwayo konke kuyisikwele.
Ukuze uhlukanise phakathi kwe-QFN ne-DFN, udinga ukucabangela izici ezimbili kuphela. Okokuqala, bheka ukuthi amaphini asezinhlangothini ezine noma ezinhlangothini ezimbili. Uma amaphini esezinhlangothini ezine, yi-QFN; uma amaphini esezinhlangothini ezimbili kuphela, yi-DFN. Okwesibili, cabanga ukuthi ukubukeka okuphelele kuyisikwele noma kuyisikwele. Ngokuvamile, ukubukeka kwesikwele kubonisa i-QFN, kanti ukubukeka kwesikwele kubonisa i-DFN.
