AOI xeem technology yog dab tsi
AOI yog ib hom tshiab ntawm kev sim thev naus laus zis uas tau nce sai hauv xyoo tas los no.Tam sim no, ntau lub tuam txhab tau tsim cov khoom siv AOI xeem.Thaum kuaj pom tsis siv neeg, lub tshuab cia li luam theej duab PCB los ntawm lub koob yees duab, sau cov duab, sib piv cov pob qij txha kuaj nrog cov kev tsim nyog hauv cov ntaub ntawv, tshawb xyuas qhov tsis xws luag ntawm PCB tom qab ua cov duab, thiab qhia / cim qhov tsis xws ntawm PCB los ntawm cov zaub los yog tsis siv neeg lub cim rau cov neeg ua haujlwm kho.
1. Lub hom phiaj ntawm kev ua tiav: kev siv AOI muaj ob lub hom phiaj tseem ceeb hauv qab no:
(1) kawg qhov zoo.Saib xyuas lub xeev kawg ntawm cov khoom thaum lawv tawm ntawm cov kab ntau lawm.Thaum qhov teeb meem ntau lawm yog qhov tseeb heev, cov khoom sib xyaw yog siab, thiab qhov ntau thiab ceev yog qhov tseem ceeb, lub hom phiaj no nyiam dua.AOI feem ntau yog muab tso rau ntawm qhov kawg ntawm cov kab ntau lawm.Hauv qhov chaw no, cov khoom siv tuaj yeem tsim ntau yam kev tswj cov ntaub ntawv.
(2) Txheej txheem taug qab.Siv cov cuab yeej tshuaj xyuas los saib xyuas cov txheej txheem tsim khoom.Feem ntau, nws suav nrog cov ncauj lus kom ntxaws qhia qhov tsis xws luag thiab cov ntaub ntawv kev tso kawm offset.Thaum cov khoom lag luam ntseeg tau yog qhov tseem ceeb, tsis tshua muaj kev sib xyaw ntau lawm, thiab cov khoom siv ruaj khov, cov tuam ntxhab muab qhov tseem ceeb rau lub hom phiaj no.Qhov no feem ntau xav kom cov cuab yeej tshuaj xyuas tau muab tso rau hauv ntau txoj haujlwm ntawm cov kab ntau lawm los saib xyuas cov xwm txheej tshwj xeeb hauv online thiab muab lub hauv paus tsim nyog rau kev hloov kho cov txheej txheem ntau lawm.
2. Qhov chaw tso chaw
Txawm hais tias AOI tuaj yeem siv tau rau ntau qhov chaw ntawm cov kab ntau lawm, txhua qhov chaw tuaj yeem kuaj xyuas qhov tsis xws luag, AOI tshuaj xyuas cov cuab yeej yuav tsum tau muab tso rau hauv ib txoj haujlwm uas feem ntau cov teeb meem tuaj yeem txheeb xyuas thiab kho sai li sai tau.Muaj peb qhov chaw soj ntsuam tseem ceeb:
(1) Tom qab ntawv luam tawm.Yog tias cov txheej txheem luam ntawv muab tshuaj txhuam tau ua tau raws li qhov yuav tsum tau ua, tus naj npawb ntawm cov teeb meem kuaj pom los ntawm ICT tuaj yeem txo qis heev.Tej yam tsis xws luam ntawv muaj xws li cov hauv qab no:
A. Tsis txaus solder ntawm lub ncoo.
B. Muaj ntau ntau solder ntawm lub ncoo.
C. Qhov sib tshooj ntawm solder thiab pad tsis zoo.
D. Solder choj ntawm cov ntaub qhwv.
Hauv ICT, qhov tshwm sim ntawm qhov tsis xws luag ntawm cov xwm txheej no ncaj qha rau qhov hnyav ntawm qhov xwm txheej.Ib qho me me ntawm cov tin tsis tshua muaj ua rau muaj qhov tsis xws luag, thaum muaj mob hnyav, xws li qhov pib tsis muaj tin tag nrho, yuav luag txhua zaus ua rau muaj qhov tsis xws luag hauv ICT.solder tsis txaus tej zaum yuav yog ib qho ntawm cov uas ploj lawm Cheebtsam los yog qhib solder pob qij txha.Txawm li cas los xij, kev txiav txim siab qhov chaw tso AOI yuav tsum lees paub tias qhov kev poob qis yuav yog vim muaj lwm yam uas yuav tsum tau suav nrog hauv txoj kev tshuaj ntsuam xyuas.Kev tshuaj xyuas ntawm qhov chaw no feem ntau ncaj qha txhawb kev taug qab cov txheej txheem thiab tus cwj pwm.Cov txheej txheem ntau yam tswj cov ntaub ntawv nyob rau theem no suav nrog luam tawm offset thiab solder kom muaj nuj nqis cov ntaub ntawv, thiab cov ntaub ntawv zoo txog cov ntawv luam tawm kuj tau tsim.
(2) Ua ntej reflow soldering.Kev tshuaj xyuas ua tiav tom qab cov khoom tau muab tso rau hauv cov khoom siv tshuaj pleev xim rau ntawm lub rooj tsavxwm thiab ua ntej PCB raug xa mus rau qhov cub reflow.Qhov no yog qhov chaw raug tso rau lub tshuab tshuaj ntsuam xyuas, vim tias feem ntau qhov tsis xws luag los ntawm kev luam ntawv luam tawm thiab kev tso tshuab tuaj yeem pom ntawm no.Cov txheej txheem ntau tswj cov ntaub ntawv tsim tawm ntawm qhov chaw no muab cov ntaub ntawv calibration rau high-speed film machines thiab kaw spaced element mounting khoom.Cov ntaub ntawv no tuaj yeem siv los hloov kho qhov chaw tso lossis qhia tias tus mounter yuav tsum tau calibrated.Kev tshuaj xyuas ntawm qhov chaw no ua tau raws li lub hom phiaj ntawm kev taug qab cov txheej txheem.
(3) Tom qab reflow soldering.Kev tshuaj xyuas ntawm cov kauj ruam kawg ntawm cov txheej txheem SMT yog qhov kev xaiv nrov tshaj plaws rau AOI tam sim no, vim tias qhov chaw no tuaj yeem txheeb xyuas txhua qhov yuam kev.Kev tshuaj xyuas tom qab reflow muab kev ruaj ntseg siab vim tias nws txheeb xyuas qhov yuam kev tshwm sim los ntawm kev luam ntawv paste, cov khoom tso rau hauv, thiab cov txheej txheem reflow.
