QFN thiab DFN, ob hom kev ntim khoom semiconductor, feem ntau yooj yim tsis meej pem hauv kev ua haujlwm.Nws feem ntau tsis paub meej tias qhov twg yog QFN thiab qhov twg yog DFN.Yog li, peb yuav tsum nkag siab tias QFN yog dab tsi thiab DFN yog dab tsi.
QFN yog ib hom kev ntim khoom.Nws yog lub npe uas txhais los ntawm Nyiv Electronics thiab Machinery Industries Association, nrog thawj tsab ntawv ntawm txhua tus ntawm peb lo lus Askiv sau.Hauv Suav, nws yog hu ua "square flat non-lead pob."
DFN yog qhov txuas ntxiv ntawm QFN, nrog rau thawj tsab ntawv ntawm txhua ntawm peb lo lus Askiv sau.
Cov pins ntawm QFN ntim tau muab faib rau tag nrho plaub sab ntawm pob thiab tag nrho cov tsos yog square.
Cov pins ntawm DFN ntim tau muab faib rau ob sab ntawm lub pob thiab tag nrho cov tsos yog duab plaub.
Txhawm rau paub qhov txawv ntawm QFN thiab DFN, koj tsuas yog yuav tsum xav txog ob yam.Ua ntej, saib seb cov pins nyob ntawm plaub sab lossis ob sab.Yog hais tias tus pins nyob rau tag nrho plaub sab, nws yog QFN;Yog tias cov pins tsuas yog ntawm ob sab, nws yog DFN.Qhov thib ob, xav txog seb lub ntsej muag tag nrho yog square lossis duab plaub.Feem ntau, lub ntsej muag square qhia QFN, thaum lub duab plaub qhia tias DFN.
