I-QFN kunye ne-DFN, ezi ntlobo zimbini zokupakishwa kwecandelo le-semiconductor, zihlala zibhideka ngokulula kumsebenzi osebenzayo.Kuhlala kungacaci ukuba yeyiphi i-QFN kwaye yeyiphi eyi-DFN.Ngoko ke, kufuneka siqonde ukuba yintoni i-QFN kwaye yintoni i-DFN.
I-QFN luhlobo lokupakisha.Ligama elichazwe yiJapan Electronics and Machinery Industries Association, enobumba bokuqala begama ngalinye kwamathathu esiNgesi anoonobumba abakhulu.NgesiTshayina, ibizwa ngokuba yi "square flat no-lead package."
I-DFN sisongezo se-QFN, unobumba wokuqala wegama ngalinye kwamathathu esiNgesi anoonobumba abakhulu.
Izikhonkwane zokupakishwa kwe-QFN zisasazwa kuwo onke macala omane epakethe kwaye imbonakalo iyonke isikwere.
Izikhonkwane ze-DFN zokupakisha zisasazwa kumacala amabini epakethe kwaye ukubonakala ngokubanzi kuxande.
Ukwahlula phakathi kwe-QFN kunye ne-DFN, kufuneka uqwalasele izinto ezimbini kuphela.Okokuqala, jonga ukuba izikhonkwane zimacala amane okanye amacala amabini.Ukuba izikhonkwane zikumacala omane, yi-QFN;ukuba izikhonkwane zikumacala amabini kuphela, yi-DFN.Okwesibini, qwalasela ukuba imbonakalo iyonke isikwere okanye uxande.Ngokuqhelekileyo, inkangeleko yesikwere ibonisa i-QFN, ngelixa ukubonakala kwexande kubonisa i-DFN.
