Kev Tswj Xyuas Qhov Kub ntawm SMT Reflow Cub kom Zoo Dua Qhov Vuam Zoo
Muaj teeb meem tswj qhov kub ntawm qhov cub Reflow thaum lub sijhawm tsim khoom? Tus qauv teeb tsa no yuav pab tau
Hauv cov txheej txheem tsim khoom SMT (Surface Mount Technology), qhov tseeb ntawm kev tswj qhov kub ntawm lub qhov cub reflow ncaj qha txiav txim siab qhov zoo ntawm kev vuam thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob. Txawm tias qhov sib txawv me me tuaj yeem ua rau muaj qhov tsis zoo xws li cov pob qij txha txias, qhov khoob, lossis kev puas tsuaj ntawm cov khoom.
RICH FULL JOY Electronics, raws li kev paub dhau los ntawm kev tsim khoom PCBA thiab kev txawj ntse, tau tsim "Reflow Oven Temperature Profile Setting Standard," muab cov lus qhia txog kev tshawb fawb, kev ua haujlwm, thiab kev siv tau rau SMT reflow qhov cub tswj qhov kub.
Txheej Txheem Txheeb Xyuas
Cov qauv no siv rau txhua lub qhov cub reflow hauv peb lub rooj cob qhia SMT, nrog cov kws tshaj lij SMT engineers uas muaj lub luag haujlwm teeb tsa thiab tswj cov qauv kub kom ntseeg tau tias qhov kub thiab txias raug thaum vuam.
Kev Npaj Cov Cuab Yeej
Yuav kom ntsuas thiab teeb tsa cov qauv kub kom raug, cov cuab yeej hauv qab no yuav tsum muaj: PROFILE tester, cov xov hlau thermocouple, cov laug cam PCB tiag tiag rau kev ntsuas, cov hnab looj tes tiv thaiv, thiab cov lus qhia txog cov tshuaj nplaum solder.
Kev Teeb tsa Cov Qauv
1. Lub Hauv Paus Siv Los Ua Piv Txwv
Teem cov kev teeb tsa xws li tus nqi nce, qhov kub ua ntej, thiab qhov kub rov ua dua raws li cov yam ntxwv ntawm cov tshuaj nplaum sib txawv (piv txwv li, tsis muaj txhuas, cov tshuaj nplaum uas muaj txhuas).
2. Lub Hauv Paus Ntsuas
Cov qauv kub yuav tsum tau ntsuas rau ntawm cov laug cam PCB tiag tiag kom qhia tau qhov tseeb ntawm cov teebmeem ntawm qhov chaw tsim khoom tiag tiag rau kev hloov pauv cua sov.
3. Cov Qauv Dav Dav
· Tus Nqi Nce Mus: 1–4 ℃ / s
Thaj Chaw Ua Kub Ua Ntej: 150–200 ℃, 60–120s
· Thaj Chaw Rov Ua Dua: ≥220 ℃ rau 30–60 vib nas this
Kub Tshaj Plaws: 235–250 ℃
·Tus nqi txias:
4. Cov Kev Cai Tshwj Xeeb
Kho qhov profile raws li cov lus tawm tswv yim zoo ntawm cov khoom lossis ua raws li cov neeg siv khoom xav tau.
5. Cov Kev Ntsuas Kho Mob I-Glue
Qhov kub ntawm I-glue yog 120 ℃, lub sijhawm kho yog 90-150 vib nas this, thiab qhov siab tshaj plaws yog 170 ℃.
Cov kev ceev faj
1. Kev Ntsuas Txhua Hnub
Yuav tsum tau ua thiab sau cia qhov kev sim kub tag nrho tom qab qhib hluav taws xob lossis hloov kab ntau lawm txhua hnub.
2. Lub Chaw Haujlwm
Tsuas yog cov kws tshaj lij SMT engineers thiaj li tau tso cai hloov kho qhov chaw teeb tsa kub.
3. Kev Ua Raws Li Cov Lus Qhia Txog Cov Neeg Siv Khoom
Teem cov txheej txheem raws li cov neeg siv khoom xav tau reflow.
4. Kev Txij Nkawm Khoom Siv
Ua qhov kev ntsuam xyuas cua ntawm lub qhov cub reflow txhua rau lub hlis, kom ntseeg tau tias kev ua haujlwm ruaj khov. Qhov sib txawv ntawm qhov kub thiab txias ntawm thaj chaw yuav tsum tsis pub tshaj 70 ℃.
Xaus lus
Los ntawm kev siv "Reflow Oven Temperature Profile Setting Standard," RICH FULL JOY Electronics ua kom muaj kev vuam SMT zoo, txhim kho kev ntseeg siab ntawm kev tsim khoom thiab kev ua haujlwm ntawm cov khoom, thiab pab cov neeg siv khoom kom nrawm dua lub sijhawm mus rau kev ua lag luam thiab tau txais txiaj ntsig sib tw.
