Ntau lub tuam txhab hluav taws xob xav tias kev yuav lub tshuab reflow loj dua tuaj yeem ua tau raws li cov kev xav tau ntawm kev ua haujlwm, tab sis feem ntau nws raug nqi nyiaj ntau thiab txi rau qhov chaw nyob.8 mus rau 10 cheeb tsam reflow thiab ceev txoj siv ceev yuav yog qhov zoo tshaj plaws kev daws teeb meem nyob rau hauv ib tug high ntim ntau lawm ib puag ncig, tab sis peb cov kev paub tau pom tias qhov me me, yooj yim dua, pheej yig dua 4 mus rau 6 cheeb tsam qauv yog peb tus neeg muag khoom zoo tshaj plaws thiab ua haujlwm zoo heev. ntawm tuav de thiab qhov chaw throughput, raws li solder paste manufacturers 'reflow specifications, thiab muab txhim khu kev qha, hwm soldering kev kawm.Tab sis ua li cas koj thiaj paub tseeb?Muaj pes tsawg cov khoom tuaj yeem ua 4-zone, 5-zone lossis 6-zone reflow txheej txheem?Qee qhov kev suav yooj yim raws li cov ntaub ntawv muab los ntawm cov tshuaj txhuam thiab cov khoom siv yuav muab rau koj siv tau zoo heev
Solder paste cua sov lub sij hawm
Thawj qhov uas yuav tsum tau xav txog yog koj cov chaw tsim khoom siv tshuaj txhuam cov tshuaj pom zoo rau cov txheej txheem muab tshuaj txhuam koj yuav siv.Solder paste manufacturers feem ntau muab lub qhov rais dav dav (nyob rau hauv cov nqe lus ntawm tag nrho cov cua sov lub sij hawm) rau ntau theem ntawm reflow profile - 120 mus rau 240 vib nas this rau preheat thiab soak lub sij hawm, thiab 60 mus rau 120 vib nas this rau reflow lub sij hawm / sij hawm saum lub xeev cov kua.Peb tau pom lub sijhawm nruab nrab ntawm tag nrho cov cua sov ntawm 4 mus rau 4½ feeb (240-270 vib nas this) los ua ib qho kev kwv yees zoo.Rau qhov kev suav yooj yim no, peb xav kom koj tsis quav ntsej qhov txias ntawm cov welded profiles.Kev ua kom txias yog qhov tseem ceeb, tab sis feem ntau yuav tsis cuam tshuam qhov zoo ntawm cov khoom siv tshwj tsis yog tias PCB txias sai heev.
Qhov ntev ntawm rhuab reflow qhov cub
Qhov kev txiav txim siab tom ntej yog tag nrho cov reflow cua sov lub sij hawm, yuav luag tag nrho cov reflow manufacturers yuav muab lub reflow cua sov ntev, tej zaum hu ua cua sov qhov ntev, nyob rau hauv lawv specifications.Hauv kev suav yooj yim no, peb tsuas yog tsom mus rau thaj chaw reflow qhov twg cov cua sov tshwm sim.
siv ceev
Rau txhua qhov rov qab uas koj siv, faib cov cua sov ntev (hauv ntiv tes) los ntawm tag nrho cov kev pom zoo lub sijhawm cua sov (hauv vib nas this).Tom qab ntawd muab 60 vib nas this kom tau txoj siv ceev hauv nti ib feeb.Piv txwv li, yog tias koj lub sijhawm kub kub yog 240-270 vib nas this thiab koj tab tom xav txog 6-zone reflow nrog 80¾ nti qhov, faib 80.7 ntiv tes los ntawm 240 thiab 270 vib nas this.Muab faib los ntawm 60 vib nas this, qhov no qhia rau koj tias koj yuav tsum tau teem lub reflow siv ceev ntawm 17.9 nti ib feeb thiab 20.2 nti ib feeb.Thaum koj txiav txim siab txoj siv ceev uas koj xav tau rau qhov rov qab uas koj tab tom xav txog, koj yuav tsum txiav txim siab qhov siab tshaj plaws ntawm cov laug cam ib feeb uas tuaj yeem ua tiav hauv txhua qhov rov qab.
Qhov siab tshaj plaws ntawm reflow phaj ib feeb
Piv txwv tias ntawm lub peev xwm siab tshaj plaws koj yuav tsum thauj cov laug cam kawg-rau-kawg ntawm lub qhov cub reflow lub conveyor, nws yooj yim los xam qhov siab tshaj tawm.Piv txwv li, yog tias koj lub rooj tsavxwm ntev 7 ntiv tes thiab txoj siv ceev ntawm 6-zone reflow qhov cub yog li ntawm 17.9 ntiv mus rau 20.2 ntiv taw ib feeb, qhov siab tshaj plaws rau qhov rov qab yog 2.6 txog 2.9 boards ib feeb.Uas yog hais, lub sab sauv thiab sab hauv Circuit Court boards yuav soldered nyob rau hauv li 20 vib nas this.
Qhov Reflow Qhov cub yog qhov zoo tshaj plaws rau koj cov kev xav tau
Ntxiv nrog rau cov xwm txheej saum toj no, muaj ntau yam ntxiv los xav txog.Piv txwv li, ob tog ntau lawm yuav xav tau reflowing ob sab ntawm tib lub ntsiab, thiab phau ntawv sib dhos ua haujlwm kuj tuaj yeem cuam tshuam ntau npaum li cas reflow muaj peev xwm tiag tiag.Yog tias koj lub rooj sibtham SMT nrawm heev, tab sis lwm cov txheej txheem txwv tsis pub koj lub Hoobkas dhau los, ces lub ntiaj teb qhov loj tshaj plaws reflow tsis zoo rau koj.Lwm qhov yuav tsum tau xav txog yog lub sijhawm hloov pauv ntawm ib yam khoom mus rau lwm qhov.Nws siv sijhawm ntev npaum li cas rau qhov ntsuas kub ntawm reflow kom ruaj khov thaum hloov ntawm ib qho kev teeb tsa mus rau lwm qhov?Muaj ntau yam sib txawv los xav txog.
Chengyuan Kev Lag Luam tau tsom mus rau reflow soldering, yoj soldering, thiab txheej tshuab rau ntau tshaj kaum xyoo.Txais tos hu rau Chengyuan engineers los xaiv qhov tsim nyog reflow soldering rau koj.
