SMT SPI khoom yog dab tsi?

Taw qhia

In the field of modern electronics manufacturing (EMS/SMT), PCBs are rapidly evolving toward higher density and miniaturization (such as 01005 and 008004 components, as well as fine-pitch BGAs). Raws li qhov sib txawv ntawm lub ncoo txuas ntxiv zuj zus, qhov tseeb xav tau rau kev luam ntawv luam tawm tau mus txog qib micrometer.

Kev lag luam txheeb cais qhia tau hais tias ntawm tag nrho cov soldering tsis xws luag nyob rauSMT cov kab ntau lawm, ntau tshaj 60% mus rau 70% los ntawm covsolder paste luam ntawvtheem.

Txhawm rau cuam tshuam qhov tsis xws luag thaum ntxov hauv kev tsim khoom, txo cov nqi rov ua haujlwm, thiab txhim kho cov txheej txheem tawm los,solder paste soj ntsuam cov cuab yeejtau dhau los ua ib qho tseem ceeb ntawm kev tswj xyuas qhov zoo hauv cov kab ntau lawm SMT.

SMT SPI Cov Khoom Siv Ua Dab Tsi?

1. SPI feem ntau yog siv rau Solder Paste Printing Quality Inspection

Cov cuab yeej SPI tshwj xeeb yog tsim los tshuaj xyuas qhov zoo ntawm cov tshuaj pleev xim rau ntawm PCBs tom qab luam ntawv. Nws lub luag haujlwm tseem ceeb yog ua cov kev soj ntsuam morphological thiab cov ntaub ntawv kom muaj nuj nqis ntawm solder paste ntawm PCB pads siv lub qhov muag pom kev pom tseeb-tom qab solder paste luam ntawv tiav thiab ua ntej qhov kev tso kawm.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias SPI tshuaj xyuas "cov txiaj ntsig luam ntawv luam tawm", tsis yog cov khoom siv hluav taws xob lawv tus kheej.

2. Vim li cas thiaj li yuav tsum tau soj ntsuam tom qab solder paste printing?

Hauv kev tsim SMT ib txwm muaj, kev tshuaj xyuas qhov muag lossis tso siab rau ntawm lub tshuab luam ntawv tsis tuaj yeem txheeb xyuas qhov ntim peb sab thiab qhov siab ntawm cov tshuaj txhuam. Yog tias muaj teeb meem luam ntawv tshwm sim thiab tsis pom nyob rau lub sijhawm, lub rooj tsav xwm Circuit Court yuav mus rau qhov kev tso kawm thiab rov ua cov txheej txheem rov ua dua. Cov teeb meem xws li luv luv Circuit Court, tombstones, tsis txaus solder, los yog voids uas tsim tom qab soldering yuav ua rau rework nqi rau skyrocket thiab tej zaum yuav ua rau lub rooj tsavxwm raug scrapped.

SPI tuaj yeem kuaj pom cov kev tsis sib xws hauv qab no:

• Solder paste txoj hauj lwm offset
• Qhov txawv txav ntawm cov tshuaj txhuam hniav ntim (Volume High / Low)
• Qhov txawv txav ntawm qhov chaw muab tshuaj txhuam (Tej cheeb tsam loj heev / me)
• Qhov siab tsis zoo solder paste qhov siab (qhov siab dhau / qis)
• Solder paste spikes, bridging, lossis localized underprinting / solder deficiency

Cov teeb meem luam ntawv dhau los tau raug kuaj pom, qhov yooj yim dua rau cov kws tsim khoom los ntxuav thiab rov luam tawm PCB lossis kho cov tshuab luam ntawv tsis ua ntej muab tso rau hauv, yog li ua kom zoo dua tus nqi tswj.

3. Lub luag haujlwm ntawm SPI hauv SMT Cov Kab Ntau Lawm

Tus txheej txheem zoo automated SMT ntau lawm kab txheej txheem yog raws li nram no:

Solder Paste tshuab luam ntawv -----> Cov cuab yeej tshuaj xyuas SPI -----> Pick-and-Place Machine -----> Reflow Qhov cub -----> AOI Inspection

SMT SPI ua haujlwm li cas?

Kev tshuaj xyuas kev ua haujlwm rau tus qauv 3D SPI feem ntau muaj plaub kauj ruam:

Track Conve ───► Mark Lub Koob Yees Duab Alignment ───► 3D Raster Scan ───► Pass / Fail & Qhia

1. PCB nkag mus rau hauv cov khoom siv SPI

PCB nkag mus rau hauvSPI tshuabntawm ib qho automated khiav, qhov twg ib tug clamping thiab positioning mechanism ruaj ntseg nws mus rau lub kho qhov muag tshuaj xyuas platform.

• Phau Ntawv Qhia Xaiv:CovNeoDen S1txhawb PCB qhov ntau thiab tsawg los ntawm qhov tsawg kawg nkaus ntawm 50 × 50 hli mus rau qhov siab tshaj plaws ntawm 500 × 460 hli, nrog lub rooj tsav xwm thicknesses los ntawm 0.6 mus rau 6 hli, npog feem ntau ntawm kev lag luam tswj, automotive electronics, thiab cov neeg siv khoom siv hluav taws xob.

2. Mark Alignment thiab PCB Identification

Lub koob yees duab kev lag luam nrhiav thiab ua raws li cov ntsiab lus preset ntawm PCB, kho qhov me me qhov sib txawv thiab deformations uas tshwm sim thaum lub sij hawm thauj khoom. NeoDen S1 txhawb cov ntsiab lus ntawm ntau cov ntsiab lus siv feem ntau (xws li Mark 0, Mark 1), tso cai rau kev kho qhov muag nrawm nrawm ncaj qha hauv software interface.

3. 3D Vision-Based Solder Paste Data Acquisition

Lub kaw lus siv lub koob yees duab 3D kho qhov muag (xws li lub koob yees duab 3D raster nrog raster projection) los tsim cov qauv raster mus rau thaj tsam scanned. Los ntawm kev siv cov hauv paus ntsiab lus ntawm kev hloov kho qhov muag thiab triangulation, nws ntes peb-dimensional topographic cov ntaub ntawv ntawm solder paste nto. NeoDen S1 ib txhij muab cov duab tiag tiag ntawm ob qho tib si 2D thiab 3D cov duab tseeb xim, ua kom pom kev pom ntawm cov ntaub ntawv ntsuas.

4. Cov ntaub ntawv pov thawj ntawm kev soj ntsuam thiab SPC cov ntaub ntawv

Cov cuab yeej SPI tsis tsuas yog tso tawm cov txiaj ntsig ntawm OK / NG lub sijhawm tiag tiag rau cov ntaub qhwv ib tus neeg tab sis kuj suav nrog cov ntaub ntawv tag nrho rau Kev Tswj Xyuas Txheej Txheem Txheej Txheem (SPC). NeoDen S1 muaj lub zog Offline SPC thiab SPC Daim Ntawv Qhia Txog Kev Ua Haujlwm, txhawb nqa kev xa tawm ntawm cov ntaub ntawv tshuaj ntsuam xyuas-xws li ntim, cheeb tsam, qhov siab, thiab offset-rau hom xws li Excel, JPG, thiab BMP, ua kom muaj txiaj ntsig zoo thiab txhim kho cov txheej txheem.

Dab tsi yog qhov txawv ntawm 2D SPI thiab 3D SPI?

2. Vim li cas 3D solder paste soj ntsuam tau txais kev saib xyuas hauv SMT ntau lawm?

Nyob rau hauv cov txheej txheem pad loj loj, 2D ntsuas yuav ua tau raws li qhov yuav tsum tau ua. Txawm li cas los xij, thaum cuam tshuam nrog cov khoom me me (xws li 01005) lossis cov rooj sib txoos zoo, cov feeb hloov pauv hauv qhov siab thiab qhov ntim feem ntau yog thawj qhov ua rau muaj qhov tsis xws luag. Thickness cov ntaub ntawv tsis tuaj yeem tau los ntawm cov duab ob sab ib leeg. Yog li ntawd, 3D SPI cov cuab yeej nruab nrog 3D raster lub koob yees duab tau dhau los ua tus qauv kev lag luam rau cov kab niaj hnub, zoo SMT ntau lawm.

Qhov txawv ntawm SPI thiab AOI yog dab tsi?

Qhov no yog ib qho ntawm feem ntau cov ntsiab lus tsis meej pem hauv SMT kev yuav khoom thiab kev npaj txheej txheem. Txawm hais tias ob qho tib si yog automated kev soj ntsuam cov tshuab, lawv ua lub luag haujlwm sib txawv ntawm cov kab ntau lawm:

Xaus:SPI thiab AOI tsis yog kev sib koom ua ke; es, lawv tsim ib qho ntxiv "dual quality defense line."

Yuav xaiv SMT SPI Khoom Siv Li Cas?
