Taw qhia
Hauv -kev tswj hwm qhov chaw ntawm PCBA kev tsim khoom, kev hloov pauv zoo ntawm lawv tus kheej tsis txaus ntshai. Dab tsi yog qhov ceeb toom yog qhov ua rau thaj tsam ntawm kev tsis sib haum xeeb thaum tsis quav ntsej txog kev tshem tawm cov hauv paus hauv paus. DMR (Defective Material Report) thiab CAPA (Kev Kho thiab Tiv Thaiv Kev Ua Haujlwm) tsim cov ncej ntxaib ntawm kev tswj hwm tus nqi siab. Yog tias DMR yog tus scalpel hais txog cov teeb meem tshwj xeeb, ces CAPA yog lub cev tiv thaiv kab mob tiv thaiv lub Hoobkas kev noj qab haus huv tag nrho.
Triggering DMR: Precise Capture of Anomalies
Cov txheej txheem DMR tau pib tam sim ntawd thaum QA txheeb xyuas cov khoom tsis xws luag thaum kuaj kab lossis kev kuaj zaum kawg, lossis thaum IQC pom tias cov khoom xa tuaj tsis yog- ua raws. Lub siab -DMR zoo tsis yog luv luv, nws yuav tsum suav nrog cov yam ntxwv ntawm lub cev ntawm qhov tsis xws luag, qhov chaw ua haujlwm qhov twg nws tshwm sim, cov lej batch koom nrog, thiab kev ntsuas kev cais tawm ua ntej.
Rau cov luv luv los yog cov khoom tsis zoo hauv kev ua PCBA, DMRs yuav tsum suav nrog siab - daws teeb meem cov duab microscopic thiab AOI cov ntaub ntawv yuam kev. Qhov kev txiav txim tseem ceeb yog kev tuav pov hwm: tam sim ntawd kaw kev ua haujlwm - hauv - kev nce qib ntawm cov kab ntau lawm thiab tag nrho cov ntaub ntawv los ntawm tib pawg hauv kev khaws cia. Qhov no tiv thaiv kev nce ntxiv thiab tsim qhov chaw rau kev soj ntsuam tsis ua haujlwm tom ntej. Qhov kev muaj peev xwm teb sai sai no ncaj qha txiav txim siab lub Hoobkas qhov kev tiv thaiv kev hloov pauv sai sai.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: Siv 5-Vim li cas thiaj li pom cov teeb meem hauv qab
Kev ua tiav ntawm DMR tsis qhia txog qhov kawg ntawm cov txheej txheem. Rau kev rov tshwm sim lossis siab -kev pheej hmoo tsis zoo, kev hloov pauv mus rau txheej txheem CAPA yog qhov yuav tsum tau ua. Nyob rau theem no, tus ntoo khaub lig- pab pawg ua haujlwm (feem ntau suav nrog Cov Txheej Txheem, Cov Khoom Siv, Kev Zoo, thiab Kev Muag Khoom) yuav tsum ua qhov kev tshuaj xyuas sib sib zog nqus siv 5-Vim li cas lossis daim duab pob txha.
Piv txwv li, tsis txaus solder sib koom lub zog tom qabreflow solderingtej zaum yuav superficially tshwm raws li qhov cub kub nkhaus fluctuations. Txawm li cas los xij, kev tshawb nrhiav tob dua tuaj yeem nthuav tawm cov txheej txheem tswj xyuas cov khoom siv tsis txaus, cov neeg ua haujlwm tshiab txhais tsis raug rau thaj chaw kub, lossis txawm tias kev yuav khoom hloov pauv flux tsis tau ceeb toom rau engineering. Hauv kev tsim PCBA, 90% ntawm cov teeb meem zoo rov qab mus rau qhov tsis muaj kev tswj hwm hauv "5M" lub ntsiab lus: txiv neej, tshuab, khoom siv, qauv, thiab ib puag ncig. Tsuas yog los ntawm kev hais txog cov hauv paus hauv paus hauv kev tswj hwm qib tuaj yeem kho cov kev ua tau zoo mus ntev.
Kev Siv CAPA: Los ntawm Point- mus rau -Kim Kho Kom Zoo Rau Cov Qauv Txheej Txheem
Kev kho kom raug daws teeb meem tam sim ntawd, thaum cov kev tiv thaiv tiv thaiv kev rov tshwm sim ntawm lwm cov kab ntau lawm lossis cov haujlwm yav tom ntej.
- Txheeb xyuas qhov ua tau zoo:Tom qab siv kev txhim kho, kaw yuav tsum tsis txhob cia siab rau ntawm daim ntawv tshaj tawm uas tau kos npe. Cov ntaub ntawv yuav tsum tau sau los ntawm me me -batch sim ntau lawm, nrog txuas ntxiv taug qab ntawm thawj- kis tawm los ntawm 3-5 batch kom paub meej tias qhov tsis xws luag raug tshem tawm tag nrho.
- Cov ntaub ntawv Standardization:Qhov no yog cov kauj ruam uas saib tsis taus. Ua tiav CAPA yuav tsum tau muab txhais ua cov txheej txheem kev ua haujlwm tshiab, tswj cov phiaj xwm, lossis FMEA databases. Piv txwv li, kev hloov kho stencil aperture tsim qauv tuaj yeem txo cov kev pheej hmoo ntawm kev sib txuas rau cov pob pins tshwj xeeb. Qhov kev paub txog kev sib koom ua ke no qhia txog kev hloov pauv tseem ceeb los ntawm kev paub-raws li kev tswj hwm digital hauv cov chaw tsim khoom.
Kaw-Loop Management: Tsim kom muaj peev xwm ceeb toom ntxov hauv cov ntaub ntawv zoo
Hauv cov chaw tsim khoom digitalized PCBA, txhua DMR thiab CAPA tau kaw rau hauv lub kaw lus, tsim lub dashboard zoo. Los ntawm kev txheeb xyuas cov ntaub ntawv keeb kwm yav dhau los, cov pab pawg ua tau zoo tuaj yeem kwv yees lub voj voog rov tshwm sim ntawm cov hom tsis ua haujlwm tshwj xeeb.
Thaum lub kaw lus pom qhov nce tsis ntev los no hauv DMR zaus rau ib qho tshwj xeeb, kev yuav khoom tuaj yeem pib qhov kev tshuaj xyuas tus neeg muag khoom. Qhov kev kaw no - lub voj voog tshuab hloov CAPA los ntawm kev tawm tsam hluav taws mus rau pem hauv ntej - saib kev tiv thaiv zoo. Nws tsis tsuas yog txhim kho cov khoom ua ntej- kis tawm los tab sis kuj txo cov nqi zais uas cuam tshuam nrog kev rov ua dua tshiab.
