Kev tsim khoom siv hluav taws xob siv cov tshuab hluav taws xob saum npoo av (SMT) yooj yooj yim txhais tau tias cov khoom siv hluav taws xob sib sau ua ke nrog cov tshuab siv tshuab uas tso cov khoom sib txuas saum npoo ntawm pawg thawj coj (luam daim ntawv lub rooj tsavxwm, PCB). Hauv kev sib piv rau cov txheej txheem ntawm lub tshuab loj (THT) cov txheej txheem, SMT cov khoom siv tau muab tso ncaj ncaj rau saum npoo ntawm PCB tsis txhob ua rau cov hlau tsis muaj hau. Thaum nws los txog rau kev sib dhos hluav taws xob, SMT yog qhov feem ntau siv cov txheej txheem hauv kev lag luam.
Hluav taws xob sib dhos ua ke tsis yog tsuas yog tso thiab soldering Cheebtsam rau PCB, tab sis kuj ua cov theem hauv qab kev tsim khoom:
Thov soldering muab tshuaj , uas yog ua los ntawm tin hais thiab flux, mus rau lub PCB
Tso cov SMT Cheebtsam coj los txuas rau soldering ntawm PCB
Soldering cov laug cam nrog cov txheej txheem reflow.
Thov Caw Daim Ntawv Cuam Tshuam
Ua ntawv thov soldering muab tshuaj txhuam yog ib qho ntawm thawj kauj ruam hauv txheej txheem SMT los ua ke. Soldering paste yog "luam tawm" ntawm cov laug cam siv txoj kev luam xim-npo. Ua raws li cov qauv siv ntawm lub rooj tsavxwm, stencils sib txawv stainless-steel rau "luam ntawv" qhov muab tshuaj txhuam rau hauv lub rooj tsavxwm thiab ntau yam khoom lag luam tshwj xeeb raug siv. Siv lub laser txiav stainless-hlau stencil kev cai ua rau qhov project, muab tshuaj txhuam soldering kom koj tsuas yog siv rau thaj chaw uas cov cheebtsam yuav raug soldered. Tom qab qhov muab tshuaj txhuam muag nyob ntawm cov laug cam, 2D-soldering paste tshuaj xyuas kom paub tseeb tias qhov muab tshuaj txhuam tusyees thiab raug siv. Thaum cov neeg muaj tseeb ntawm daim ntawv thov los lo lus thov soldering tau paub tseeb hais tias, cov laug cam yog pauv mus rau SMT los ua ke kab, qhov twg lub Cheebtsam yuav muab soldered.
Cheeb Tsam Chaw Tso Chaw thiab Kev Sib Daws
Cov khoom siv hluav taws xob yuav tsum sib sau tuaj nyob hauv cov tais los yog reels, uas tom qab ntawd thau khoom rau hauv tshuab SMT . Thaum lub sijhawm thauj khoom, cov software software ntse xyuas kom meej tias cov khoom siv tsis txhob cia li hloov pauv lossis yuam kev. Lub SMT los ua ke tshuab tom qab ntawd txiav tawm txhua ntu nrog lub tshuab nqus dej ntawm nws lub tais lossis lus rov thiab muab tso rau nws txoj haujlwm tseeb ntawm lub rooj tsavxwm uas siv cov txheej txheem ua ntej XY ua haujlwm. Peb lub tshuab muaj peev xwm sib sau tau txog 25,000 yam hauv ib teev. Tom qab SMT sib dhos ua tiav, cov laug cam tau rhais mus rau ntawm Reflow ncu rau soldering, uas affixes lub Cheebtsam rau pawg thawj coj.
Kev Muag Khoom Tiv Thaiv Ib Leeg
Txhawm rau solder hluav taws xob Cheebtsam, peb siv ob txoj kev sib txawv, txhua tus muaj qhov sib txawv zoo nyob ntawm qhov kev txiav txim ntau. Rau cov series txiav txim ntau lawm, cov txheej txheem Reflow-soldering siv. Thaum cov txheej txheem no, cov laug cam muab tso rau hauv qhov chaw tso pa nitrogen thiab maj mam ua kom sov nrog cua kub kom txog thaum cov ntawv ci soldering yaj thiab flux vaporizes, uas cuam tshuam rau cov khoom sib xyaw rau PCB. Tom qab theem no, cov laug cam txias dua. Raws li cov yajthem hauv cov kabmob muab tshuaj ua kom tawv, lub Cheebtsam ua kom ruaj khov mus rau kev tswjhwm thiab SMT kev sib dhos ua tiav.
Rau kev ua qauv lossis cov cheeb tsam uas tsis tshua muaj neeg siab, peb muaj cov txheej txheem tshwj xeeb vapor-theem soldering. Nyob rau hauv txoj kev no, cov laug cam ua tiav kom txog thaum muab cov nplauv sib xyaw (Galden) ntawm cov zom zaws uas hu ua tiav. Qhov no pub peb ham tsawg dua kub lossis solder txawv SMT Cheebtsam ntawm qhov kub sib txawv nyob ntawm lawv tus kheej kub profile.
AOI thiab Kos Duab Tshawb Pom
Soldering yog qib thib ob-rau-kawg ntawm txheej txheem SMT los ua ke. Txhawm rau kom ntseeg tau tias qhov zoo tshaj plaws ntawm cov rooj sib sau ua ke, lossis txhawm rau txhom thiab txhim kho qhov ua yuam kev, AOI qhov kuaj pom yog ua rau yuav luag txhua daim ntawv txiav txim. Kev siv ntau lub koob yees duab, AOI system cia li kuaj txhua lub rooj tsavxwm thiab muab piv rau txhua lub rooj sib txig nrog cov duab kom raug, muaj cim ua ntej. Yog tias muaj cov kev hloov pauv, tus neeg teb xov tooj ntawm lub tshuab tau paub txog qhov teeb meem muaj peev xwm, leej twg tom qab kho qhov yuam kev lossis rub lub rooj tsavxwm los ntawm lub tshuab rau kev tshuaj xyuas ntxiv. AOI kev kuaj pom pom tseeb tias xwm yeem thiab raug nyob hauv SMT cov txheej txheem sib dhos ntau lawm.
