Nyob rau hauv xyoo tas los no, nrog rau kev nce hauv cov kev xav tau ntawm cov khoom siv ntse xws li cov xov tooj ntse thiab cov ntsiav tshuaj, SMT kev lag luam muaj kev xav tau ntau dua rau cov khoom siv me me thiab thinning ntawm cov khoom siv hluav taws xob.Nrog kev nce ntawm cov khoom siv hnav, qhov kev thov no ntau dua.nce ntxiv.Daim duab hauv qab no yog kev sib piv ntawm I-phone 3G thiab I-phone 7 motherboards.Lub xov tooj ntawm tes I-phone tshiab muaj zog dua, tab sis cov motherboard sib sau ua ke me dua, uas yuav tsum muaj cov khoom me me thiab cov khoom ntom ntom.Kev sib dhos tuaj yeem ua tiav.Nrog rau cov khoom me me thiab cov khoom me me, nws yuav dhau los ua nyuaj rau peb cov txheej txheem ntau lawm.Kev txhim kho ntawm tus nqi dhau los tau dhau los ua lub hom phiaj tseem ceeb ntawm SMT cov txheej txheem engineers.Feem ntau hais lus, ntau dua 60% ntawm qhov tsis xws luag hauv SMT kev lag luam yog cuam tshuam nrog kev luam ntawv luam tawm, uas yog txheej txheem tseem ceeb hauv SMT ntau lawm.Kev daws qhov teeb meem ntawm solder paste printing yog sib npaug rau kev daws teeb meem feem ntau ntawm cov txheej txheem SMT tag nrho.
Daim duab hauv qab no yog cov lus sib piv ntawm cov metric thiab imperial qhov ntev ntawm SMT cov khoom.
Cov duab hauv qab no qhia txog keeb kwm kev loj hlob ntawm SMT cov khoom thiab cov kev loj hlob zoo saib rau yav tom ntej.Tam sim no, British 01005 SMD li thiab 0.4 pitch BGA / CSP feem ntau siv hauv SMT ntau lawm.Ib qho me me ntawm metric 03015 SMD cov khoom siv kuj tseem siv rau hauv kev tsim khoom, thaum metric 0201 SMD cov cuab yeej tam sim no tsuas yog nyob rau theem kev sim tsim khoom thiab xav tias yuav maj mam siv hauv kev tsim khoom hauv ob peb xyoos tom ntej no.
