I-QFN kunye ne-DFN, ezi ntlobo zimbini zecandelo le-semicondcuctor, zihlala zididekile ngomsebenzi owenziwayo. Ihlala ingacacanga yi-QFN kwaye yeyiphi i-DFN. Ke ngoko, kufuneka siqonde ukuba yintoni i-QNN kunye ne-DFN.
I-QFN luhlobo lokupakisha. Ligama elichazwe yi-elektroniki ye-elektroniki kunye noMatshini weMizi-mveliso yoMatshini, kunye nonobumba wokuqala we-English nganye yesiNgesi. NgesiTshayina, ibizwa ngokuba "yiphakheji yeflethi yeflethi."
I-DFN yindawo eyandisiweyo ye-QFN, kunye nonobumba wokuqala wayo nganye yamagama amathathu esiNgesi abelwe.
Izikhonkwane zenkqubo ye-QFN zisasazwa kuwo onke amacala omgangatho kunye nenkangeleko epheleleyo sisikwere.
Izikhonkwane zephakheji ze-DFN zisasazwa kumacala amabini ephakheji kwaye inkangeleko iyonke ingumba ongxamisekileyo.
Ukwahlula phakathi kwe-QFN kunye ne-DFN, kuya kufuneka uqaphele izinto ezimbini. Okokuqala, jonga ukuba izikhonkwane zingamacala amane okanye amacala amabini. Ukuba izikhonkwane zikuwo onke amacala omane, yi-QFN; Ukuba izikhonkwane zingamacala amabini kuphela, yi-DFN. Okwesibini, qwalasela ukuba inkangeleko iyonke iyisikwere okanye inxandereni. Ngokubanzi, imbonakalo yesikwere ibonisa i-QFN, ngelixa inkangeleko yoxande ibonisa i-DFN.
