ThaumSMT AOI tshuabtuaj yeem siv rau ntawm ntau qhov chaw ntawm SMT cov kab ntau lawm txhawm rau txheeb xyuas qhov tsis xws luag, AOI tshuaj xyuas cov cuab yeej yuav tsum tau muab tso rau hauv qhov chaw uas qhov tsis xws luag feem ntau tuaj yeem txheeb xyuas thiab kho kom sai li sai tau.Muaj peb qhov chaw kuaj xyuas tseem ceeb:
Tom qab solder paste yog luam tawm
Yog tias cov txheej txheem luam ntawv solder paste ua tau raws li qhov yuav tsum tau ua, tus lej ntawm ICT tsis xws luag tuaj yeem txo qis.Tej yam tsis xws luam ntawv muaj xws li cov hauv qab no:
A. Insufficient soldering tin ntawmstencil tshuab luam ntawv.
B. Ntau dhau ntawm cov nplaum nplaum.
C. Tsis zoo coincidence ntawm solder rau solder ncoo.
D. Solder choj ntawm cov ntaub qhwv.
Hauv ICT, qhov tshwm sim ntawm qhov tsis xws luag ntawm cov xwm txheej no yog ncaj qha ncaj qha rau qhov hnyav ntawm qhov xwm txheej.Tsawg me ntsis tin tsis tshua muaj ua rau muaj qhov tsis xws luag, thaum mob hnyav, xws li cov tin hauv paus, yuav luag txhua zaus ua rau muaj qhov tsis xws luag hauv ICT.Tsis zoo solder tej zaum yuav ua rau cov khoom poob los yog qhib cov 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 tshwm sim rau lwm qhov laj thawj uas yuav tsum tau suav nrog hauv txoj kev tshuaj ntsuam xyuas.Qhov kev tshuaj xyuas qhov chaw no feem ntau ncaj qha txhawb cov txheej txheem taug qab thiab ua tus cwj pwm.Cov txheej txheem tswj cov ntaub ntawv nyob rau theem no suav nrog kev luam tawm offset thiab cov ntaub ntawv ntim cov ntaub ntawv, thaum cov ntaub ntawv zoo txog cov ntawv luam tawm kuj raug tsim.
Ua ntejreflow qhov cub
Kev tshuaj xyuas yog ua tiav tom qab cov khoom siv tau muab tso rau hauv cov tshuaj pleev xim rau ntawm lub rooj tsavxwm thiab ua ntej lub PCB raug pub rau hauv qhov cub reflow.Qhov no yog ib qho chaw zoo rau tso lub tshuab tshuaj ntsuam xyuas, vim tias feem ntau qhov tsis xws luag los ntawm solder paste luam ntawv thiab kev tso tshuab tuaj yeem pom ntawm no.Cov txheej txheem kev tswj kom muaj nuj nqis tsim tawm ntawm qhov chaw no muab cov ntaub ntawv qhia txog kev ntsuas lub siab ceev cov tshuab nti thiab cov khoom siv sib txuas sib ze.Cov ntaub ntawv no tuaj yeem siv los hloov kho qhov chaw tso khoom lossis qhia tias tus mounter xav tau calibration.Kev tshuaj xyuas ntawm qhov chaw no ua tau raws li lub hom phiaj ntawm cov txheej txheem taug qab.
Tom qab reflow soldering
Txheeb xyuas qhov kawg ntawm cov txheej txheem SMT, uas yog qhov kev xaiv nrov tshaj plaws rau AOI, vim tias qhov no yog qhov uas txhua qhov kev sib dhos yuam kev tuaj yeem pom.Kev tshuaj xyuas tom qab rov qab rov qab muab qhov kev nyab xeeb siab vim tias nws txheeb xyuas qhov yuam kev tshwm sim los ntawm kev luam ntawv luam tawm, cov khoom sib txuas, thiab cov txheej txheem rov qab.
