Tam sim no kev lag luam yog cov khoom siv hluav taws xob ntau heev, ua cov txheej txheem kuj zoo heev, tsuav yog qhov tsim qauv siv hluav taws xob hauv ntau yam khoom ntse, yuav siv lub rooj tsav xwm Circuit Court no, cov hauv qab no rau koj los piav qhia cov txheej txheem. ntawm SMT ntau lawm los tsim cov kab nrib pleb yog vim li cas.
SMT kev ua cov vuam tawg ua rau feem ntau yog cov hauv qab no
1. Circuit Board pads thiab cov khoom ntawm cov vuam nto infiltration tsis tau raws li qhov yuav tsum tau ua ntawm kev tsim khoom thiab kev ua haujlwm.
2. Flux paste tsis ua raws li cov qauv tsim raws li xav tau.
3. Soldering thiab hluav taws xob theem ntawm ntau yam khoom siv thermal expansion coefficient tsis sib luag, qhov chaw vuam nyob rau hauv lub condensation ntawm lub sij hawm tsis ruaj khov.
4. Reflow qhov cubsoldering kub profile ntawm tus txheej txheem teeb tsa tsis muaj txhais tau tias tso cai rau cov flux muab tshuaj nyob rau hauv cov organic chemicals thiab cov dej ntws rov qab mus rau pem hauv ntej ntawm evaporation ntawm cheeb tsam.
5. Qhov nyuaj ntawm cov ntaub ntawv tsis muaj hmoov txhuas ntawm cov txheej txheem smt yog qhov kub thiab txias, siab interfacial nro, thiab viscosity siab. Lub siab nro ntawm lub interface yuav yeej ua rau lub vapor tawm ntawm lub txias txheej txheem nyuaj, cov pa roj tsis yooj yim rau paug, uas yuav ua rau cov feem pua ntawm cov kab nrib pleb ntau heev, vim hais tias ntawm cov hlau lead-free soldering nyob rau hauv ib co thaj ua rau muaj. yuav ntau tawm ntawm cov pa roj thiab cov kab nrib pleb.
6. Tsis tas li ntawd, qhov kub ntawm cov hlau lead-free soldering yuav ntau dua li cov hlau lead soldering, tshwj xeeb tshaj yog nyob rau hauv qee qhov loj ntawm lub rooj tsavxwm multilayer, thiab thermal conductivity ntawm cov khoom siv hluav taws xob, tus nqi siab ntawm qhov kub yog feem ntau ua. 260 degrees los yog li ntawd, lub tub yees condensation mus rau sab hauv tsev ntawm qhov kub thiab txias qhov sib txawv ntawm qhov kub thiab txias yuav loj heev, yog li cov hlau lead-free soldering ntawm cov kev ntxhov siab hauv av kuj tseem loj heev.

1. Ua-nyob rau hauv vuam fume filtration system, zoo filtration ntawm teeb meem gases, zoo nkauj tsos thiab ib puag ncig tiv thaiv, ntau nyob rau hauv txoj kab nrog kev siv high-end ib puag ncig.
2. Cov kev tswj xyuas muaj cov yam ntxwv ntawm kev sib koom ua ke siab, cov lus teb raws sij hawm, tsis tshua muaj nqi, kev saib xyuas yooj yim, thiab lwm yam.
3. Mus txog rau 4-txoj kev ntawm lub sijhawm tiag tiag ntawm PCB board nto vuam kub nkhaus.
4. Lub teeb yuag, miniaturization, kev tsim muaj kev lag luam, hloov tau yooj yim daim ntawv thov scenarios, ntau tib neeg.
5. Kev txuag hluav taws xob, kev siv hluav taws xob tsawg, kev siv hluav taws xob tsawg, hluav taws xob zoo tib yam tuaj yeem ua tau raws li kev siv, piv rau cov khoom zoo sib xws hauv ib xyoos tuaj yeem txuag nqi hluav taws xob thiab tom qab ntawd yuav 1 chav tsev ntawm cov khoom no.
6. Independent circulating cua tsim ntawm qhov chaw txias, tag nrho cais los ntawm ib puag ncig sab nraud ntawm qhov kub thiab txias hauv kab noj hniav.
7. Los ntawm qhov tshwj xeeb airflow simulation software sim optimized vuam fume filtration system, tuaj yeem ua tiav qhov pom ntawm cov pa phem tib lub sijhawm los xyuas kom meej tias cov khoom siv plhaub kom tswj tau qhov kub thiab txias, txo cov cua sov thiab txo lub zog noj.
