Yuav ua li cas PCB sib dhos manufacturers kom PCB zoo?

Raws li thev naus laus zis txuas ntxiv mus, cov ntawv luam tawm Circuit Board (PCBs) tau dhau los ua cov khoom tseem ceeb ntawm ntau cov khoom siv hluav taws xob. Los ntawm cov xov tooj smartphones mus rau cov khoom siv kho mob, PCBs ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm kom zoo ntawm cov khoom siv no. Yog li ntawd, PCB los ua ke manufacturers yuav tsum ua raws li nruj soj ntsuam thiab soj ntsuam cov txheej txheem los lav qhov zoo ntawm lawv cov khoom.Hauv tsab ntawv tshaj tawm no, peb yuav tshawb txog ntau cov kauj ruam thiab ntsuas cov tuam txhab lag luam ua kom ntseeg tau zoo tshaj PCBs.

Initial Visual Inspection:

Thawj kauj ruam hauv cov txheej txheem tswj kev ua tau zoo yog kev soj ntsuam pom ntawm PCB. PCB los ua ke cov tuam txhab ua tib zoo tshuaj xyuas cov rooj sib tham hauv lub cev kom muaj qhov tsis xws luag xws li khawb, dents, lossis cov khoom puas. Qhov kev tshuaj xyuas thawj zaug no pab txheeb xyuas cov teeb meem pom uas yuav cuam tshuam rau PCB kev ua tau zoo lossis kev ntseeg siab.

kev xeem ua haujlwm:

Tom qab kev tshuaj xyuas thawj zaug tiav, cov chaw tsim khoom pib mus rau kev sim ua haujlwm. Cov kauj ruam no suav nrog kev ntsuas hluav taws xob ua haujlwm ntawm PCB los ntawm kev ua ntau yam kev ntsuam xyuas ntawm PCB. Cov kev ntsuam xyuas no txheeb xyuas tias PCB ua haujlwm raws li qhov xav tau thiab ua tau raws li qhov xav tau tshwj xeeb. Kev sim ua haujlwm tuaj yeem suav nrog cov kev sim xws li kev ntsuas hluav taws xob, ntsuas qhov ntsuas nkag, ntsuas qhov ntsuas kev ncaj ncees, thiab ntsuas ciam teb ntsuas.

Automated Optical Inspection (AOI):

Txhawm rau kom ntseeg tau tias qhov zoo thiab qhov tseeb ntawm PCB cov rooj sib txoos, cov tuam txhab feem ntau siv cov khoom siv kho qhov muag kho qhov muag (AOI) tshuab. AOI siv lub koob yees duab daws teeb meem los ntes cov duab ntawm PCBs sib dhos. AI-tsav software tom qab ntawd muab cov duab no sib piv rau cov qauv siv, txheeb xyuas qhov tsis sib xws xws li cov khoom ploj lawm, kev sib raug zoo lossis kev tsis sib haum xeeb. AOI txhim kho qhov tseeb thiab ceev ntawm kev soj ntsuam, thiab tuaj yeem tshawb pom txawm tias qhov tsis xws luag uas yuav tsum tau kuaj xyuas.

X-ray soj ntsuam:

Rau cov PCBs nyuaj nrog cov khoom zais lossis tsis pom, kev kuaj x-ray tuaj yeem pab tau. Kev kuaj X-ray tso cai rau cov neeg tsim khoom pom los ntawm cov txheej txheem ntawm PCB thiab kuaj pom muaj qhov tsis xws luag, xws li cov txuas txuas txuas lossis cov voids. Txoj kev kuaj tsis muaj kev puas tsuaj no pab txheeb xyuas cov teeb meem uas tsis tuaj yeem tshawb pom los ntawm kev tshuaj xyuas qhov muag lossis AOI, ua kom muaj kev ncaj ncees thiab kev ua haujlwm ntawm PCB.

Online Test (ICT):

Kev ntsuam xyuas hauv Circuit Court (ICT) yog lwm kauj ruam tseem ceeb hauv kev tswj xyuas qhov zoo. Thaum lub sijhawm ICT txheej txheem, cov tuam txhab tsim khoom siv cov cuab yeej tshwj xeeb los ntsuas kev ua haujlwm ntawm tus kheej thiab cov khoom siv hluav taws xob ntawm PCB. Los ntawm kev siv cov voltages tshwj xeeb thiab cov teeb liab, tus tester tuaj yeem kuaj xyuas txhua yam tsis ua haujlwm, luv Circuit Court lossis qhib Circuit Court. ICT pab txheeb xyuas cov khoom tsis raug lossis kev sib txuas uas tuaj yeem ua rau PCB ua tsis tau lossis ua tiav ntawm nws qhov zoo.

Kev kuaj kev laus:

Txhawm rau ntsuas qhov kev cia siab ntev ntev thiab kev ruaj ntseg ntawm PCBs, cov tuam ntxhab feem ntau ua qhov ntsuas kub rau lawv. Kev ntsuas hluav taws xob cuam tshuam nrog kev nthuav tawm PCB rau qhov kub thiab txias (feem ntau tshaj nws qhov kev ua haujlwm ntau) rau lub sijhawm ntev. Qhov kev ntsuam xyuas nruj no pab txheeb xyuas qhov muaj peev xwm tsis zoo lossis qhov tsis muaj zog ntawm cov khoom siv thiab ua kom ntseeg tau tias PCB tuaj yeem tiv taus kev ua haujlwm ib txwm tsis ua haujlwm.

Environmental xeem:

Txij li PCBs tuaj yeem cuam tshuam los ntawm ntau yam ib puag ncig, nws yog ib qho tseem ceeb rau kev sim lawv cov kav ntev thiab kev ua tau zoo nyob rau hauv cov xwm txheej sib txawv. Kev ntsuam xyuas ib puag ncig cuam tshuam nrog kev nthuav tawm PCBs rau qhov kub thiab txias, av noo, kev co thiab kev poob siab. Cov kev ntsuam xyuas no ntsuas qhov tsis kam ntawm PCBs rau cov xwm txheej tsis zoo thiab xyuas kom meej tias lawv tuaj yeem tiv taus qhov xav tau ntawm cov ntawv thov tiag tiag hauv ntiaj teb.

xeem kawg:

Ua ntej PCBs raug xa mus rau cov neeg siv khoom, lawv tau txais kev soj ntsuam zaum kawg los xyuas kom meej tias lawv ua tau raws li txhua qhov kev cai. Kev tshuaj xyuas no suav nrog kev tshuaj xyuas zoo ntawm PCB qhov pom, qhov ntev, kev ua haujlwm hluav taws xob thiab kev ua haujlwm. Kev tshuaj ntsuam xyuas zaum kawg txo qis qhov ua tau ntawm PCBs raug xa mus rau cov neeg siv khoom, yog li lav cov qauv zoo tshaj plaws.

Hauv kev xaus, PCB sib dhos cov tuam txhab ua cov txheej txheem kuaj thiab tshuaj xyuas kom ntseeg tau tias lawv cov khoom zoo.Kev tshuaj xyuas qhov muag, kev sim ua haujlwm, AOI, X-ray tshuaj xyuas, ICT, kev ntsuas kub hnyiab, kev ntsuas ib puag ncig thiab kev soj ntsuam zaum kawg txhua tus ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tswj kom zoo. Los ntawm kev ua raws li cov txheej txheem no nruj me ntsis, cov tuam ntxhab tuaj yeem xyuas kom meej tias PCBs lawv tsim tau raws li cov qauv tsim nyog, yog li muab cov neeg siv khoom nrog cov khoom lag luam txhim khu kev qha thiab zoo.
