Lub hauv ntej kawg ntawm kev ua SMD yogstenciltshuab luam ntawvthiabSMTtshuab, rov qab kawg yuav tsum taureflow solderingtshuabKev kub ceev vuam, cov tshuaj txhuam hniav yuav yaj cov khoom siv hluav taws xob thiab cov ntaub qhwv kom nruj ua ke kom tsis txhob poob.Reflowqhov cubFeem ntau muaj 4 thaj chaw kub, raws li, thaj chaw tshav kub nqus, qhov kub thiab txias, thaj chaw soldering, thaj chaw txias, qhov kub ntawm qhov chaw sib txawv yuav tsum sib txawv, thiaj li ua tau zoo heev soldering zoo, yog li txhim kho qhov vuam los ntawm tus nqi, txo qhov vuam. tus nqi tsis raug. Yog li SMD ua reflow soldering kub profile tswj yog qhov tseem ceeb heev
Reflow soldering kub profile ntsuas kub, koj yuav tsum siv qhov ntsuas kub profile tester. Kev ntsuas muaj cov khoom siv, cov kab xev kub kub ruaj khov rau hauv qhov ntsuas qhov ntsuas, qhib qhov hloov pauv ntawm lub ntsuas ntsuas, ntsuas ntsuas kub nrog PCBA rau hauv qhov cub tawg, raws li cov txheej txheem kev ua haujlwm thiab kev ceev ntawm cov qauv ntsuas thiab kaw lub qhov cub kub, cov ntaub ntawv xeem tiav. , tus tester yuav txuas nrog lub tshuab luam ntawv, koj tuaj yeem luam tawm qhov ntsuas kub nkhaus ntawm qhov sib txawv ntawm qhov kub thiab txias.
Thaum siv cov ntsuas kub ntsuas, muaj cov hauv qab no yuav tsum tau muab sau tseg.
1. Kev ntsuas yuav tsum tau siv thaum lub rooj tsavxwm tau teeb tsa
Ua ntej ntawm tag nrho cov, cov thermal tsom xam ntawm cov PCB Cheebtsam, vim hais tias ntawm txawv thermal zog ntawm lub PCB, qhov luaj li cas ntawm lub Cheebtsam thiab cov khoom sib txawv, thiab lwm yam., qhov tseeb kub sawv ntawm txhua lub ntsiab lus tsis zoo ib yam, mus nrhiav tau ntau tshaj. cov ntsiab lus kub thiab txias, koj tuaj yeem ntsuas qhov kub thiab txias tshaj plaws.
2. Teeb tsa cov ntsiab lus xeem ntxiv kom paub qhov tseeb ntawm lub tshav kub
Piv txwv li, qhov nruab nrab ntawm PCBA lub rooj tsavxwm thiab ntug ntawm lub tshav kub tsis zoo ib yam, cov khoom ntim loj thiab cov khoom me me uas muaj peev xwm sib txawv thiab cov khoom siv hluav taws xob kub-rhiab yuav tsum tau teeb tsa cov ntsiab lus xeem.
3. Thermocouple sojntsuam cov duab yog me me, yuav tsum tau kho nyob rau hauv qhov kev xeem txoj hauj lwm nrog cov teev high-temperature solder los yog nplaum, txwv tsis pub tshav kub loosening, deviating los ntawm lub hom phiaj ntsuas taw tes, ua rau kev xeem yuam kev.
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. tuaj yeem khaws 40 cov ntaub ntawv ua haujlwm.
4. Mus txog rau 4-txoj kev ntawm lub sijhawm tiag tiag ntawm PCB board nto vuam kub nkhaus.
5. Lub teeb yuag, miniaturization, kev tsim muaj kev lag luam, hloov tau yooj yim daim ntawv thov scenarios, ntau tus neeg.
6. Cov phaj cua kub tshwj xeeb tsim tau zoo ua kom cov cua txias tsis sib xws tom qab cov cuab yeej nres cua sov, tiv thaiv cov khoom kom tsis txhob raug puas los ntawm qhov kub thiab txias thiab qhov tshwm sim deformation.
7. Cov qauv tsim zais zais yog yooj yim rau kev thauj mus los, siv tau yooj yim, zoo nkauj thiab dav.
8. lub kaw lus tswj siv cov chips txawv teb chaws, kev tswj qhov kub thiab txias ntawm ± 0.5 feem pua.
