Lub khw muag khoom hluav taws xob tsheb yog qhov thib peb loj tshaj plaws hauv thaj chaw thov rau PCBs tom qab khoos phis tawj thiab kev sib txuas lus. Raws li lub tsheb tau maj mam hloov zuj zus los ntawm cov khoom siv tshuab hauv cov kev xav ib txwm muaj los ua cov khoom siv high-tech uas muaj kev txawj ntse, qhia, thiab cov tshuab mechatronics, cov cuab yeej siv hluav taws xob tau siv dav hauv tsheb, txawm tias nws yog lub cav lossis lub chassis, cov khoom siv hluav taws xob yog siv nyob rau hauv kev ruaj ntseg systems, cov ntaub ntawv systems, thiab nyob rau hauv lub tsheb ib puag ncig systems. Kev lag luam tsheb tau pom meej meej dhau los ua lwm qhov chaw ci ntsa iab hauv kev lag luam khoom siv hluav taws xob. Txoj kev loj hlob ntawm automotive electronics tau ib txwm tsav txoj kev loj hlob ntawm automotive PCBs.
Hauv cov ntawv thov tseem ceeb niaj hnub no rau PCBs, automotive PCBs tuav txoj haujlwm tseem ceeb. Txawm li cas los xij, vim qhov chaw ua haujlwm tshwj xeeb, kev nyab xeeb thiab siab tam sim no ntawm lub tsheb, nws cov kev xav tau ntawm PCB kev ntseeg siab thiab kev hloov pauv ib puag ncig yog siab, thiab hom PCB thev naus laus zis koom nrog kuj tseem dav. Qhov no yog qhov teeb meem loj rau cov tuam txhab PCB. Kev sib tw; thiab rau cov tuam txhab uas xav tsim kho tsheb PCB kev ua lag luam, kev nkag siab ntau ntxiv thiab kev tshuaj xyuas ntawm lub khw tshiab no yog xav tau.
Automotive PCBs hais txog kev ntseeg siab thiab qis DPPM. Yog li, peb lub tuam txhab puas muaj cov khoom siv thev naus laus zis thiab kev paub hauv kev tsim khoom muaj kev ntseeg siab? Puas yog nws ua raws li cov khoom lag luam txhim kho yav tom ntej? Hais txog kev tswj cov txheej txheem, nws puas tuaj yeem ua raws li cov cai ntawm TS16949? Nws puas tau ua tiav DPPM qis? Tag nrho cov no yuav tsum tau ua tib zoo soj ntsuam. Tsuas yog pom lub ncuav mog qab zib no ntxias thiab dig muag nkag mus rau nws yuav ua rau muaj kev puas tsuaj rau lub tuam txhab nws tus kheej.
Cov hauv qab no muab cov neeg sawv cev ntawm qee qhov kev coj ua tshwj xeeb hauv kev tsim cov tuam txhab tsheb PCB thaum lub sijhawm kuaj cov txheej txheem rau feem ntau ntawm PCB cov npoj yaig rau kev siv:
1. Txoj kev xeem thib ob
Qee cov tuam txhab PCB tau txais "txoj kev sim thib ob" los txhim kho tus nqi ntawm kev nrhiav cov laug cam tom qab thawj zaug hluav taws xob tawg.
2. Phem board foolproof xeem system
Ntau thiab ntau lub tuam txhab PCB tau teeb tsa "zoo board marking system" thiab "phem board error-proof box" nyob rau hauv lub optical board kuaj tshuab kom tsis txhob muaj neeg to. Lub Rooj Tswjhwm Saib Xyuas Lub Rooj Tswjhwm Saib tau zoo ua rau lub rooj tsavxwm kuaj PASS rau lub tshuab kuaj, uas tuaj yeem tiv thaiv lub rooj tsavxwm kuaj lossis lub rooj tsavxwm tsis zoo los ntawm kev ntws mus rau hauv cov neeg siv khoom txhais tes. Lub thawv ntawv pov thawj tsis zoo yog tias thaum lub sijhawm xeem, thaum lub rooj tsavxwm PASS raug kuaj, qhov kev xeem ntawv tso tawm lub teeb liab uas lub thawv qhib; txwv tsis pub, thaum kuaj lub rooj tsavxwm tsis zoo, lub thawv kaw, tso cai rau tus neeg teb xov tooj tso lub rooj tsav xwm kuaj xyuas kom raug.
3. Tsim kom muaj PPm zoo
Tam sim no, PPm (Partspermillion, qhov chaw ib lab tus nqi tsis zoo) tau siv dav hauv PCB cov tuam txhab. Ntawm cov neeg siv khoom ntau ntawm peb lub tuam txhab, daim ntawv thov thiab kev ua tiav ntawm Hitachi ChemICal hauv Singapore yog qhov tsim nyog tshaj plaws ntawm kev siv. Nyob rau hauv lub Hoobkas, muaj ntau tshaj 20 tus neeg uas yog lub luag hauj lwm rau cov txheeb cais tsom xam ntawm online PCB zoo abnormalities thiab PCB zoo txawv txav rov qab. Siv cov txheej txheem kev txheeb xyuas ntawm SPC cov txheej txheem tsim khoom, txhua lub rooj tsav xwm tawg thiab txhua lub rooj tsav xwm rov qab tau raug cais tawm rau kev txheeb xyuas cov ntaub ntawv, thiab ua ke nrog micro-slicing thiab lwm yam cuab yeej pabcuam los tshuaj xyuas cov txheej txheem tsim cov txheej txheem tsis zoo thiab tsis zoo. Raws li cov ntaub ntawv txheeb cais, lub hom phiaj daws teeb meem hauv cov txheej txheem.
4. Txoj kev xeem sib piv
Qee cov neeg siv khoom siv ob lub qauv ntawm cov khoom sib txawv rau kev sib piv ntawm cov khoom sib txawv ntawm PCBs, thiab taug qab PPm ntawm cov khoom siv sib xws, kom nkag siab txog qhov ua tau zoo ntawm ob lub tshuab ntsuas, thiab tom qab ntawd xaiv lub tshuab ntsuas kev ua tau zoo dua los kuaj cov tsheb PCBs. .
5. Txhim kho qhov ntsuas ntsuas
Xaiv cov kev ntsuas siab dua kom nruj xyuas cov PCBs. Vim hais tias, yog tias koj xaiv qhov hluav taws xob ntau dua thiab qhov pib, ua kom cov xov tooj ntawm cov hluav taws xob nyeem cov xaim hluav taws xob ntau, tuaj yeem txhim kho qhov txheeb xyuas tus nqi ntawm PCB lub rooj tsavxwm. Piv txwv li, ib lub tuam txhab Taiwanese PCB loj hauv Suzhou tau siv 300V, 30M, thiab 20 Euros los ntsuas cov tsheb PCBs.
6. Txheeb xyuas qhov ntsuas lub tshuab ntsuas lub sijhawm
Tom qab lub sijhawm ua haujlwm ntev ntawm lub tshuab kuaj, qhov kev tiv thaiv sab hauv thiab lwm yam kev ntsuas ntsuas yuav raug deviated. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau kho lub tshuab tsis tu ncua kom paub meej qhov tseeb ntawm qhov ntsuas ntsuas. Cov cuab yeej kuaj xyuas yog tswj hwm hauv ib feem ntawm cov tuam txhab PCB loj rau ib nrab xyoo lossis ib xyoos, thiab cov kev ua haujlwm sab hauv tau hloov kho. Kev nrhiav ntawm "zero defect" PCBs rau tsheb yeej ib txwm yog cov kev taw qhia ntawm kev siv zog ntawm feem ntau ntawm cov neeg PCB, tab sis vim muaj kev txwv ntawm cov txheej txheem cov cuab yeej thiab cov khoom siv raw, cov tuam txhab saum toj kawg nkaus 100 PCB hauv ntiaj teb tseem niaj hnub tshawb nrhiav txoj hauv kev. txo PPm.
