PCB los ua ke Cov Kev Pabcuam Tsis Zoo Siv Kev Tshawb Fawb Kev Tshawb Fawb (AOI)

Automated Optical Inspection (AOI), uas yog ib qho kev tshuaj xyuas qhov muag pom ntawm lub Rooj Tswjhwm Saib Circuit Court (PCB), muab 100% pom kev tivthaiv thiab kev tshuaj xyuas kev sib koom ua ke.Txoj kev ntsuas no tau siv hauv PCB tsim rau yuav luag ob xyoo lawm.Nws plays lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias tsis muaj qhov yuam kev hauv kev sib dhos.Cov txheej txheem, uas siv cov teeb pom kev zoo, cov koob yees duab, thiab cov khoos phis tawj pom kev, tau muab tso rau hauv cov txheej txheem sib dhos kom lav qhov ua tau zoo tshaj plaws thoob plaws txhua theem ntawm cov khoom lag luam lub neej voj voog.Cov txheej txheem ua kom nrawm thiab raug kuaj xyuas thiab tuaj yeem siv rau ntau theem ntawm kev tsim khoom.Yog li, dab tsi txhua yam tuaj yeem tshawb xyuas Automated Optical Inspection (AOI) cov cuab yeej kuaj xyuas hauv ib qhoPCB sib dhos?

Kev kuaj pom tsis zoo siv AOI

Qhov kev kuaj pom sai sai, qhov yooj yim dua nws yuav ua rau cov khoom kawg kom phim cov qauv tsim yam tsis muaj qhov tsis zoo.Qhov kev paub zoo, lees paub thev naus laus zis tuaj yeem siv los kuaj xyuas cov hauv qab no hauv PCB los ua ke:

• Nodules, khawb thiab stains
• Qhib circuits, luv luv thiab thinning ntawm solder
• Tsis raug, tsis muaj thiab skewed Cheebtsam
• Tsis txaus muab tshuaj txhuam, smearing, thiab bridging
• Cov chips ploj los yog offset, skewed chips thiab chip-orientation defects
• Solder txuas hniav, thiab lifted leads
• Kab dav kev ua txhaum cai
• Kev ua txhaum qhov sib txawv
• Tshaj tooj liab, thiab nco nco nco
• Nthuav luv luv, txiav, dhia
• Cheeb tsam tsis xws luag
• Cheebtsam offset, tivthaiv polarity,
• Cov khoom muaj nyob los yog tsis muaj, cov khoom skew los ntawm nto mount pads
• Cov pob qij txha ntau dhau thiab cov pob qij txha tsis txaus
• Flipped Cheebtsam
• Muab tshuaj txhuam ib ncig ntawm cov hlau lead, cov txuas txuas, thiab cov ntawv sau npe ntawm cov tshuaj txhuam

 

Nrog rau cov teeb meem no tau raug kuaj pom nyob rau theem ntxov tshaj plaws, cov neeg tsim khoom tuaj yeem tsim lub rooj tsavxwm raws li cov qauv tsim nyog.Txhawm rau pab txhawb rau cov txheej txheem kuaj, muaj ntau yam khoom siv nrog cov teeb pom kev zoo, kho qhov muag, thiab cov duab ua kom muaj peev xwm rau qhov tshwj xeeb tsis xws luag.Cov tshuab no muab kev ua haujlwm yooj yim, ntse thiab muaj zog, ua rau txo koj cov nqi rov ua haujlwm thiab txhim kho cov txheej txheem kuaj.AOI yog ib qho tseem ceeb ntawm txoj kev ntsuam xyuas uas txiav txim siab tag nrho qhov zoo ntawm lub rooj tsavxwm, nws yog ib qho tseem ceeb kom tau txais kev pabcuam los ntawm cov tuam txhab ua lag luam.Nws yog ib qho kev xaiv zoo tshaj plaws los koom tes nrog PCB cov tuam txhab uas muab AOI kuaj tes hauv tes.Qhov no pab cov neeg tsim khoom los ntsuas lub rooj tsavxwm ntawm txhua theem ntawm kev sib dhos yam tsis muaj kev ncua.
