Tam sim no, ntau cov khoom siv hluav taws xob zoo tshaj plaws hauv tsev thiab txawv teb chaws tau tshaj tawm cov khoom siv tshiab lub tswv yim "kev saib xyuas synchronous" txhawm rau txhawm rau txo qhov cuam tshuam ntawm kev saib xyuas ntawm kev tsim khoom.Ntawd yog, thaum lub qhov cub reflow ua haujlwm ntawm qhov muaj peev xwm tag nrho, kev hloov kho tsis siv neeg hloov pauv ntawm cov cuab yeej siv los ua kev saib xyuas thiab kev saib xyuas ntawm qhov cub reflow tag nrho synchronized nrog ntau lawm.Qhov kev tsim qauv no tso tseg qhov qub "kev saib xyuas kev kaw haujlwm" lub tswv yim, thiab ntxiv dag zog rau kev tsim khoom ntawm tag nrho SMT kab.
Cov kev xav tau rau kev siv cov txheej txheem:
Cov cuab yeej siv tau zoo tsuas yog tuaj yeem tsim cov txiaj ntsig los ntawm kev siv tshaj lij.Tam sim no, ntau yam teeb meem tshwm sim los ntawm feem ntau ntawm cov tuam txhab tsim khoom hauv cov txheej txheem ntawm cov hlau lead-dawb soldering tsis tsuas yog los ntawm cov khoom siv nws tus kheej, tab sis yuav tsum tau daws los ntawm kev hloov kho hauv cov txheej txheem.
l Kev teeb tsa ntawm qhov cub kub qhov nkhaus
Vim tias cov txheej txheem ntawm cov hlau lead-dawb soldering qhov rais me me heev, thiab peb yuav tsum xyuas kom meej tias tag nrho cov pob qij txha yog nyob rau hauv lub qhov rais txheej txheem nyob rau tib lub sij hawm nyob rau hauv lub reflow cheeb tsam, yog li ntawd, cov hlau lead-dawb reflow nkhaus feem ntau teem ib tug "flat top" ( saib daim duab 9).
Daim duab 9 "Plat top" nyob rau hauv qhov cub kub qhov nkhaus qhov chaw
Yog tias cov khoom qub ntawm lub rooj tsavxwm muaj qhov sib txawv me ntsis hauv thermal muaj peev xwm tab sis muaj kev cuam tshuam ntau dua rau thermal shock, nws yog qhov tsim nyog los siv qhov "linear" cub kub nkhaus.(Saib daim duab 10)
Daim duab 10 "Linear" rauv kub nkhaus
Kev teeb tsa thiab kev hloov kho ntawm lub cub tawg kub yog nyob ntawm ntau yam xws li cov khoom siv, cov khoom qub, cov tshuaj txhuam hniav, thiab lwm yam. Cov txheej txheem teeb tsa tsis zoo ib yam, thiab kev paub yuav tsum tau sau los ntawm kev sim.
l Rauv kub nkhaus simulation software
Yog li puas muaj qee txoj hauv kev uas tuaj yeem pab peb sai thiab raug teeb tsa lub qhov cub kub qhov nkhaus?Peb tuaj yeem txiav txim siab tsim software nrog kev pab cuam ntawm qhov cub kub qhov nkhaus simulation.
Nyob rau hauv ib txwm muaj xwm txheej, tsuav yog peb qhia cov software qhov xwm txheej ntawm lub rooj tsav xwm hauv Circuit Court, qhov xwm txheej ntawm cov khoom qub, lub sijhawm ntawm lub rooj tsavxwm, cov saw nrawm, qhov kub thiab txias thiab xaiv cov khoom siv, software yuav simulate lub cub tawg kub nkhaus generated. nyob rau hauv tej yam kev mob.Qhov no yuav raug kho offline kom txog rau thaum tau txais qhov kub ntawm qhov cub kub.Qhov no tuaj yeem txuag tau lub sijhawm rau cov txheej txheem engineers rov qab kho qhov nkhaus, uas yog qhov tseem ceeb tshwj xeeb rau cov tuam txhab uas muaj ntau yam thiab cov khoom me me.
Lub neej yav tom ntej ntawm reflow soldering technology
Cov khoom siv xov tooj ntawm tes thiab cov khoom siv tub rog muaj cov kev cai sib txawv rau reflow soldering, thiab Circuit Court board ntau lawm thiab semiconductor ntau lawm muaj cov cai sib txawv rau reflow soldering.Cov khoom me me thiab cov ntim loj pib maj mam txo, thiab qhov sib txawv ntawm cov khoom siv rau cov khoom sib txawv pib tshwm sim ib hnub.Qhov sib txawv ntawm reflow soldering nyob rau hauv lub neej yav tom ntej yuav tsis tsuas yog xav txog nyob rau hauv tus naj npawb ntawm kub cheeb tsam thiab cov kev xaiv ntawm nitrogen, lub reflow soldering lag luam yuav tsum tau muab faib mus rau hauv subdivided, uas yog lub foreseeable txoj kev loj hlob kev taw qhia ntawm reflow soldering tshuab nyob rau hauv lub neej yav tom ntej.
