Kev soj ntsuam kev ua haujlwm ntawm ntau yam SMT tsos tshuaj xyuas cov cuab yeej AOI

a) : Siv los ntsuas lub tshuab luam ntawv zoo tshaj plaws SPI tom qab lub tshuab luam ntawv: SPI tshuaj xyuas yog ua tom qab solder paste luam ntawv, thiab qhov tsis zoo hauv cov txheej txheem luam ntawv tuaj yeem pom, yog li txo qhov tsis zoo ntawm cov khoom siv los ntawm cov khoom siv tsis zoo. luam ntawv kom tsawg.Kev luam ntawv tsis zoo muaj xws li cov ntsiab lus hauv qab no: tsis txaus lossis ntau dhau ntawm cov ntaub qhwv;luam ntawv offset;tin choj nruab nrab ntawm cov ntaub qhwv;thickness thiab ntim ntawm cov luam ntawv solder paste.Nyob rau theem no, yuav tsum muaj cov txheej txheem saib xyuas cov ntaub ntawv muaj zog (SPC), xws li luam tawm offset thiab solder ntim cov ntaub ntawv, thiab cov ntaub ntawv zoo txog cov ntawv luam tawm yuav raug tsim los rau kev tshuaj xyuas thiab siv los ntawm cov neeg ua haujlwm tsim khoom.Nyob rau hauv txoj kev no, cov txheej txheem yog txhim kho, cov txheej txheem yog txhim kho, thiab tus nqi txo.Cov cuab yeej no tam sim no tau muab faib ua 2D thiab 3D hom.2D tsis tuaj yeem ntsuas qhov tuab ntawm solder paste, tsuas yog cov duab ntawm cov muab tshuaj txhuam.3D tuaj yeem ntsuas ob qhov tuab ntawm cov nplaum nplaum thiab thaj tsam ntawm cov tshuaj txhuam hniav, kom cov ntim ntawm cov tshuaj txhuam tuaj yeem suav tau.Nrog rau qhov miniaturization ntawm cov khoom, lub thickness ntawm lub solder paste yuav tsum tau rau cov khoom xws li 01005 tsuas yog 75um, thaum lub thickness ntawm lwm yam loj Cheebtsam yog hais txog 130um.Ib lub tshuab luam ntawv tsis siv neeg uas tuaj yeem luam tawm sib txawv solder paste thicknesses tau tshwm sim.Yog li ntawd, tsuas yog 3D SPI tuaj yeem ua tau raws li cov kev xav tau ntawm yav tom ntej solder paste txheej txheem tswj.Yog li dab tsi ntawm SPI peb tuaj yeem ua tau raws li qhov xav tau ntawm cov txheej txheem yav tom ntej?Feem ntau cov kev xav tau no:

1. Nws yuav tsum yog 3D.
2. Kev soj ntsuam ceev ceev, tam sim no laser SPI thickness ntsuas yog qhov tseeb, tab sis qhov ceev tsis tuaj yeem ua tau raws li qhov xav tau ntawm ntau lawm.
3. Yog los yog adjustable magnification (optical thiab digital magnification yog ib qho tseem ceeb heev tsis, cov tsis muaj peev xwm txiav txim qhov kawg nrhiav tau lub peev xwm ntawm lub ntaus ntawv. Kom meej meej ntes 0201 thiab 01005 pab kiag li lawm, optical thiab digital magnification yog ib qho tseem ceeb heev, thiab nws yog tsim nyog los xyuas kom meej tias lub nrhiav pom algorithm muab rau AOI software muaj txaus daws teeb meem thiab cov ntaub ntawv duab).Txawm li cas los xij, thaum kho lub koob yees duab pixel, qhov kev nthuav dav yog inversely proportional rau FOV, thiab qhov loj ntawm FOV yuav cuam tshuam rau qhov ceev ntawm lub tshuab.Nyob rau tib lub rooj tsavxwm, cov khoom loj thiab me me muaj nyob rau tib lub sijhawm, yog li nws yog ib qho tseem ceeb uas yuav tsum xaiv qhov tsim nyog kho qhov muag los yog kho qhov muag kho qhov muag raws li qhov loj ntawm cov khoom ntawm cov khoom.
4. Kev xaiv lub teeb pom kev zoo: kev siv cov programmable teeb pom kev zoo yuav yog ib qho tseem ceeb los xyuas kom meej qhov kev kuaj pom qhov tsis zoo.
5. Ntau dua qhov tseeb thiab rov ua dua: Cov khoom siv me me ua rau qhov raug thiab rov ua dua ntawm cov cuab yeej siv hauv cov txheej txheem tsim khoom tseem ceeb dua.
6. Ultra-low misjudgment rate: Tsuas yog los ntawm kev tswj cov kev txiav txim siab tsis ncaj ncees tuaj yeem muaj, xaiv thiab ua haujlwm ntawm cov ntaub ntawv nqa los ntawm lub tshuab rau cov txheej txheem siv tiag tiag.
7. SPC txheej txheem tsom xam thiab cov ntaub ntawv tsis raug sib koom nrog AOI nyob rau hauv lwm qhov chaw: muaj zog SPC txheej txheem kev soj ntsuam, lub hom phiaj kawg ntawm kev tshuaj ntsuam xyuas yog los txhim kho cov txheej txheem, rationalize tus txheej txheem, ua kom pom lub xeev, thiab tswj cov nqi tsim khoom.

b).AOI nyob rau hauv pem hauv ntej ntawm lub cub tawg: Vim lub miniaturization ntawm Cheebtsam, nws yog ib qhov nyuaj rau kho 0201 tivthaiv qhov tsis xws luag tom qab soldering, thiab qhov tsis xws luag ntawm 01005 Cheebtsam yuav kho tsis tau.Yog li ntawd, AOI nyob rau hauv pem hauv ntej ntawm lub cub tawg yuav dhau los ua qhov tseem ceeb.Lub AOI nyob rau hauv pem hauv ntej ntawm lub cub tawg tuaj yeem kuaj xyuas qhov tsis xws ntawm cov txheej txheem kev tso kawm xws li misalignment, tsis ncaj ncees lawm qhov chaw, qhov uas ploj lawm, ntau qhov chaw, thiab rov qab polarity.Yog li ntawd, AOI nyob rau hauv pem hauv ntej ntawm lub cub tawg yuav tsum tau nyob online, thiab cov cim tseem ceeb tshaj plaws yog kev kub ceev, siab raug thiab rov ua dua, thiab kev txiav txim siab tsawg.Nyob rau tib lub sijhawm, nws tseem tuaj yeem muab cov ntaub ntawv qhia txog kev noj zaub mov, tsuas yog tshawb xyuas qhov tsis ncaj ncees lawm ntawm cov khoom siv refueling thaum lub sijhawm refueling, txo cov ntaub ntawv tsis raug, thiab tseem xa cov ntaub ntawv sib txawv ntawm cov khoom mus rau SMT programming system los hloov kho. SMT tshuab program tam sim ntawd.

c) AOI tom qab lub cub tawg: AOI tom qab lub cub tawg tau muab faib ua ob hom: online thiab offline raws li txoj kev nce qib.AOI tom qab lub cub tawg yog qhov kawg gatekeeper ntawm cov khoom, yog li nws yog tam sim no siv AOI tshaj plaws.Nws yuav tsum tau kuaj xyuas PCB qhov tsis xws luag, cov khoom tsis xws luag thiab tag nrho cov txheej txheem tsis xws luag hauv tag nrho cov kab ntau lawm.Tsuas yog peb-xim high-brightness dome LED lub teeb qhov chaw tuaj yeem ua kom pom qhov sib txawv ntawm qhov sib txawv kom pom qhov tsis xws luag.Yog li ntawd, yav tom ntej, tsuas yog AOI ntawm qhov teeb pom kev zoo no muaj chaw rau kev txhim kho.Tau kawg, yav tom ntej, txhawm rau cuam tshuam nrog PCBs sib txawv Qhov kev txiav txim ntawm cov xim thiab peb-xim RGB kuj yog programmable.Nws hloov tau ntau dua.Yog li dab tsi ntawm AOI tom qab lub cub tawg tuaj yeem ua tau raws li qhov xav tau ntawm peb qhov kev tsim khoom SMT yav tom ntej?Ntawd yog:

1. kev kub ceev.
2. High precision thiab siab repeatability.
3. High-resolution koob yees duab los yog variable-resolution koob yees duab: ua tau raws li qhov yuav tsum tau ntawm ceev thiab precision tib lub sij hawm.
4. Kev txiav txim siab tsis zoo thiab tsis tuaj yeem txiav txim siab: Qhov no yuav tsum tau ua kom zoo dua ntawm cov software, thiab kev kuaj xyuas cov yam ntxwv ntawm vuam feem ntau yuav ua rau kev txiav txim tsis raug thiab tsis raug txiav txim.
5. AXI tom qab lub cub tawg: Cov teeb meem uas tuaj yeem kuaj xyuas muaj xws li: cov pob qij txha, txuas hniav, tombstones, tsis txaus solder, pores, cov khoom uas ploj lawm, IC lifted taw, IC tsawg tin, thiab lwm yam, tshwj xeeb tshaj yog, X-RAY kuj tuaj yeem tshawb xyuas cov pob qij txha hauv qhov zais zais xws li raws li BGA, PLCC, CSP, thiab lwm yam. Nws yog ib qho zoo ntxiv rau pom lub teeb AOI.
