QFN na DFN, ubu bwoko bubiri bwo gupakira igice cya semiconductor, akenshi bitiranya byoroshye mubikorwa bifatika. Akenshi ntibisobanutse nimwe QFN niyindi DFN. Kubwibyo, dukeneye gusobanukirwa QFN icyo aricyo na DFN icyo aricyo.
QFN ni ubwoko bwo gupakira. Nizina ryasobanuwe n’Ubuyapani Electronics and Machinery Industries Association, hamwe n’inyuguti ya mbere ya buri jambo uko ari itatu ry'icyongereza ryanditse mu nyuguti nkuru. Mu Gishinwa, byitwa "kwaduka kare nta-kuyobora."
DFN niyagurwa rya QFN, hamwe ninyuguti yambere ya buri jambo ryicyongereza bitatu ryanditse mumutwe.
Amapine ya QFN apakira yatanzwe kumpande enye zose zapakiye kandi isura rusange ni kare.
Amapaki yo gupakira DFN yatanzwe kumpande ebyiri za pake kandi isura rusange ni urukiramende.
Gutandukanya QFN na DFN, ugomba gusa gusuzuma ibintu bibiri. Ubwa mbere, reba niba pin ziri kumpande enye cyangwa impande ebyiri. Niba amapine ari kumpande enye, ni QFN; niba amapine ari kumpande ebyiri gusa, ni DFN. Icya kabiri, reba niba isura rusange ari kare cyangwa urukiramende. Mubisanzwe, kare kare yerekana QFN, mugihe urukiramende rugaragaza DFN.
