Hauv kev lag luam electronics, lub luam tawm hauv Circuit Court board (PCB) yog cov khoom tseem ceeb ntawm ntau yam khoom siv hluav taws xob. Qhov zoo ntawm cov khoom ntawm PCB ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov khoom. Yog li ntawd, kev soj ntsuam zoo thiab kev ntsuam xyuas ntawm PCB boards yog kev tswj xyuas zoo ntawm PCB daim ntawv thov cov tuam txhab. Ib qhov txuas tsis tseem ceeb. Tam sim no, feem ntau ntawm PCB soldering zoo soj ntsuam ua hauj lwm yog ua los ntawm phau ntawv pom kev soj ntsuam. Kev cuam tshuam ntawm tib neeg yam yog ib qho yooj yim kom nco thiab tsis pom tseeb.

Yog li ntawd, kev lag luam PCB xav tau kev tshuaj xyuas hauv online automated, thiab cov khoom txawv teb chaws yog kim heev. Raws li qhov xwm txheej no, lub teb chaws pib tsim qhov no. Detection Systems. Daim ntawv no tsuas yog kawm txog kev txheeb xyuas ntawm PCB board vuam qhov tsis xws luag: kev txheeb xyuas cov xim nplhaib tsis kam, kev txheeb xyuas cov khoom xau vuam thiab kev txheeb xyuas cov kab hluav taws xob polarity.

Cov txheej txheem ua hauv daim ntawv no yog muab cov qauv kev sib piv thiab cov qauv kev sib piv uas tsis yog siv los muab cov duab PCB pawg thawj coj los ntawm lub koob yees duab digital, thiab siv cov txheej txheem ntawm kev tso duab, duab ua ntej thiab kev paub txog cov duab, kev rho tawm kom paub qhov tsis siv neeg nrhiav kev ua haujlwm. Los ntawm kev sim ntawm ntau cov duab PCB, txoj kev muab tso rau ntawm PCB duab nta tau txhim kho kom tau txais qhov tseeb duab tso.

Cov qauv txheej txheem ntawm kev tawg yog ib feem tseem ceeb. Qhov no yog lub rooj tsav xwm Circuit Court thiab tus qauv board. Ua thawj kauj ruam ntawm kev sib tw tiag tiag. Nyob rau hauv cov duab ua ntej ua ntej, ib txoj kev kho geometric tshiab yog siv los kho cov duab kom tau txais cov duab PCB raug thiab meej pixel tswj xyuas ntawm txhua qhov khoom, thiab ua cov duab binarization, nruab nrab filtering, ntug nrhiav pom thiab lwm txoj hauv kev kom tau txais kev lees paub zoo tshaj. Nyob rau hauv daim duab tom ntej no paub txog cov nyhuv duab, cov yam ntxwv yog muab rho tawm los ntawm cov duab tom qab preprocessing, thiab cov kev paub sib txawv yog saws rau txawv vuam tsis xws luag.

Siv cov kev txheeb cais los rho tawm tus qauv xim lub zog kom raug txheeb xyuas cov xim nplhaib tsis kam, thiab daws qhov kev txheeb xyuas ntawm cov xim nplhaib tsis kam los ntawm cov xim segmentation mus rau saturated filling. Hais txog cov yam ntxwv geometric ntawm lub ncov qaumteb qabteb capacitor, txoj kev txheeb xyuas geometric yog siv rau daim ntawv thov ntawm cov khoom xau vuam. Txoj kev paub txog qhov tseeb tau ua tiav cov txiaj ntsig zoo. Yog li ntawd, txoj kev no muaj cov txiaj ntsig zoo rau kev txheeb xyuas qhov tsis zoo ntawm PCB hauv Suav teb.
