SMT Zauvyog cov txheej txheem thev naus laus zis rau kev ua raws li tus PCB. Nws muaj qhov zoo ntawm cov siab loj mounting qhov tseeb thiab nrawm nrawm, yog li nws tau txais los ntawm ntau cov khoom lag luam hauv hluav taws xob. Tus txheej txheem SMT ua qauv ua haujlwm tsuas yog suav nrog cov kab xev cia li ua kom tiav, rov ua kom zoo nkauj lossis rov ua kom tiav cov txheej txheem tag nrho.
1.Xreen luam
Cov cuab yeej kawg hauv ntej-kawg nyob hauv SMT cov kab ntau lawm yog lub tshuab luam ntawv luam tawm lossis cov kua nplaum tseem ceeb rau cov pcb los npaj rau cov soldering ntawm cov khoom siv.
2. Dispensing
Cov khoom siv nyob rau ntawm sab xub ntiag ntawm SMT cov kab ntau lawm lossis tom qab lub tshuab tshuaj sojntsuam yog cov kua nplaum dispenser. Nws lub ntsiab muaj nuj nqi yog kom tso cov kua nplaum mus rau qhov chaw ruaj khov ntawm PCB, thiab lub hom phiaj yog txhawm rau txhim kho cov khoom siv ntawm PCB.
3. Kev Tso Npe
Cov khoom siv nyob tom qab lo lo ntxhuav npo luam ntawv tshuab hauv SMT cov kab ntau lawm yog qhov chaw kaw sab hauv kom muaj txoj hauj lwm ruaj ruaj rau ntawm PCB.
4. Kho
Cov cuab yeej tom qab tso rau hauv lub tshuab SMT ntau lawm yog kom yaj cov kua nplaum thiab kom cov pawg thawj coj sab nrauv thiab tus kab mob PCB tau sib raug zoo ua ke.
5. Reflow Soldering
Cov cuab yeej tom qab tso rau hauv lub tshuab SMT cov kab ntau lawm yog cov tshuaj tiv thaiv kab npoo thiab cov kab mob PCB tau sib raug zoo ua ke.
6. Nrhiav tau
Txhawm rau kom ntseeg tau tias kev sib dhos zoo thiab ua ke zoo ntawm lub rooj sib tham pcb board tau raws li lub Hoobkas tsim tawm, ntsuas hluav taws xob (AOI), x-ray tshuaj ntsuam cov tshuab thiab lwm yam cuab yeej tshuaj xyuas. Lub luag haujlwm tseem ceeb yog los xyuas seb tus PCB board muaj cov tsis xws luag xws li virtual soldering, uas ploj lawm soldering, thiab nrib pleb.
7. Ntxuav
Tej zaum yuav muaj cov soldering cov lus uas ua rau muaj kev phom sij rau tib neeg lub cev xws li flux ntawm cov rooj sib tham PCB board, uas yuav tsum tau ntxuav nrog lub tshuab ntxuav.
