Embonini yezimoto, ikhwalithi yezingxenye ze-elekthronikhi ithinta ngqo ukusebenza nokuphepha kwemoto, lapho i-PCB ingenye yezingxenye eziyinhloko. Ngakho-ke, kubaluleke kakhulu ukukhetha umphakeli webhodi le-automotive electronics PCB board. Ngakho-ke, ungamkhetha kanjani umphakeli webhodi le-automotive electronics PCB? Namuhla ngizokunikeza isingeniso esinemininingwane yokuqinisekisa ukuzinza kwe-supply chain kanye nekhwalithi ephezulu yemikhiqizo.
一． Qonda izidingo ezikhethekile ze-automotive electronic PCB
1. Ukuthembeka: Ama-PCB e-Automotive electronic adinga ukusebenza isikhathi eside ngaphandle kokwehluleka.
2. Umthelela wendawo: Kumelwe uvumelane nezimo ezinjengamazinga okushisa aphezulu naphansi, izinguquko ezinkulu zomswakama, nokudlidliza.
3. Ukuthobelana nezindinganiso zomkhakha: njenge-ISO 26262 (izinga lamazwe ngamazwe lezinhlelo zikagesi eziphathelene nokuphepha kwezimoto), i-IPC-A-600 ne-IPC-6012 (izindinganiso zokukhiqiza ne-PCB zokwamukela).
二、Hlola amakhono obuchwepheshe abahlinzeki nolwazi
1. Iziqu zobungcweti: Ukuthi umphakeli unezitifiketi ezifanele zesistimu yokuphathwa kwekhwalithi, njenge-ISO 9001, IATF 16949 (uhlelo lokuphatha ikhwalithi lomkhakha wezimoto).
2. Amandla ezobuchwepheshe: Amakhono okucwaninga nokuthuthukisa omphakeli emikhakheni yobuchwepheshe ethuthukisiwe ye-PCB efana nefrikhwensi ephezulu kanye nokudluliswa kwesignali yesivinini esikhulu.
3. Izinsizakalo ezenziwe ngokwezifiso: Ukuthi izixazululo ze-PCB ezenziwe ngezifiso zinganikezwa ngokuya ngezidingo ezikhethekile zogesi wezimoto.
三、Hlola ukuzinza nokungafihli kwe-supply chain
1. Umthombo wezinto zokusetshenziswa: Abahlinzeki abahle kakhulu bazosebenzisa izinto zokwakha zekhwalithi ephezulu futhi banikeze obala emthonjeni wezinto zokwakha.
2. Amandla okukhiqiza: Qonda izindawo zokukhiqiza zomphakeli kanye nemigqa yokukhiqiza ukuze ubone ukuthi akhona yini amandla okukhiqiza anele ukuhlangabezana nezidingo zakho.
3. Ikhono lokubhekana nezimo eziphuthumayo: Uma kwenzeka ukuphazamiseka kokuhlinzeka, ingabe umphakeli unalo uhlelo oluphuthumayo lokuqinisekisa ukuthi ukukhiqizwa akuthinteki?
四、Hlola inqubo yokulawula ikhwalithi yomhlinzeki
1. Izindlela zokuhlola ikhwalithi: Abahlinzeki kufanele babe nezindawo zokuhlola eziphelele nezindlela, njengokuhlola i-X-ray, ukuhlola okuzenzakalelayo kokubona (i-AOI), njll.
2. Uhlelo lokulandeleka: Abahlinzeki be-PCB bekhwalithi ephezulu bazoba nohlelo oluphelele lokulandelela umkhiqizo olungalandelela umlando wokukhiqiza nowokuhlola we-PCB ngayinye.
3. Impendulo yekhasimende: Ukuqonda impendulo yekhasimende ekhona yomphakeli, ikakhulukazi impendulo yekhasimende ehlobene nezimoto, kunganikeza ulwazi olubalulekile lwereferensi.
Lapho ukhetha umphakeli webhodi le-automotive electronics PCB, udinga ukucabangela ngokucophelela izici eziningi. Ngokuhlaziya okungenhla, ungakwazi ekuqaleni ukuhlola abahlinzeki abanolwazi lwemboni, amakhono aqinile ezobuchwepheshe, ikhwalithi ethembekile kanye nesevisi ecabangelayo, ucabangela ukusimama kokubambisana kwesikhathi eside. , kunconywa ukuthi kusungulwe ubudlelwano besikhathi eside nobuzinzile bokusebenzisana nabahlinzeki ukuze kubhekwane ngokuhlanganyela nezinselele ezingaba khona zesikhathi esizayo embonini yezimoto.
Izidingo zokwenza ngokwezifiso zebhodi le-PCB ye-automotive electronic
Ngokuthuthuka okusheshayo kobuchwepheshe be-automotive electronics, i-PCB iya ngokuya isetshenziswa
ku-elekthronikhi yezimoto. Kusukela kumasistimu okulawula injini kuya kumasistimu ezikhwama zomoya kuya ezinhlelweni ezithuthukisiwe zokusiza ukushayela, ikhwalithi nokusebenza kwamabhodi e-PCB kuthinta ngqo ukuphepha kwemoto. Izindinganiso nezimfuneko eziqinile kufanele zilandelwe lapho kwenziwa ngendlela oyifisayo amabhodi e-PCB kagesi ezimoto. Ngakho, ake sibheke. Qonda izimfuneko zokwenza ngokwezifiso zamabhodi e-PCB e-automotive electronic.
1. Ukukhetha izinto ezibonakalayo
Ukukhethwa kwezinto ezibonakalayo zamabhodi e-PCB ezimoto kubaluleke kakhulu. Ingasebenza ngokuzinza ngaphansi kwezimo zemvelo ezimbi kakhulu. Izinga lokushisa eliphezulu, izinga lokushisa eliphansi, umswakama, ukudlidliza kanye nokungcola yizo zonke izici okufanele zicatshangelwe. Izinto ezisetshenziswa kakhulu zebhodi le-PCB zifaka i-FR-4, i-PTFE (i-polymer) i-Tetrafluoroethylene) nezinto ezisekelwe ensimbi, njll., zinganikeza amandla anele emishini nokuzinza kokushisa.
2. Imininingwane yokuklama
Lapho wenza ngendlela oyifisayo amabhodi e-PCB e-automotive electronic, imininingwane yedizayini ibaluleke kakhulu. Ngokuvamile zimboza ubukhulu bebhodi, inani lezendlalelo, ukujiya kwe-foil yethusi, ubukhulu kanye nesikhala samaphedi, ububanzi bomugqa/isikhala somugqa, njll. Kuma-PCB ezimoto, ukunakwa okukhethekile kuyadingeka. Ukuklanywa kongqimba lwamandla ayo kuqinisekisa ukuzinza nokusabalalisa okufanayo kwamanje.
3. Ukuphathwa kokushisa
Ngenxa yezici zokushisa eziphakeme zemvelo yezimoto, ukuphatha okushisayo sekube yinto ebalulekile yokucatshangelwa lapho uklama amabhodi e-PCB e-automotive electronic. Umklamo oshisayo onengqondo awukwazi kuphela ukuqinisekisa ukusebenza okuzinzile kwezingxenye ze-elekthronikhi, kodwa futhi wandise impilo yesevisi yomkhiqizo. Amasu okuphatha okushisayo asetshenziswa ngokuvamile ahlanganisa ukusebenzisa izinto ze-substrate ezine-conductivity enhle yokushisa, ukuklama izindlela zokuqhuba ukushisa okuphumelelayo, nokwengeza ama-radiator noma amapayipi okushisa.
4. Ukusebenza kukagesi
Amabhodi e-PCB ezimoto kufanele abe nezakhiwo zikagesi ezinhle kakhulu, okuhlanganisa amandla e-dielectric anele, ukumelana nokufakwa kahle kwe-insulation namandla e-anti-electromagnetic interference (EMI), ikakhulukazi ezinhlelweni zokuphepha nokulawula izimoto. Noma yiluphi uhlobo lokuhluleka kukagesi lungabangela imiphumela emibi kakhulu.
5. Ukuhlolwa kanye nesitifiketi
Wonke amabhodi e-PCB e-automotive electronic enziwe ngokwezifiso adinga ukuthi adlule ekuhlolweni okuqinile kanye nenqubo yokunikeza izitifiketi ukuze aqinisekise ukusebenza kwawo nokuphepha ezinhlelweni zokusebenza zangempela. Lezi zivivinyo zingabandakanya ukuhlolwa kukagesi, ukuhlolwa kokufaneleka kwemvelo, ukuqinisekiswa kokusebenza, njll., futhi kufanele futhi kuthobelane ne-IATF 16949, ISO 9001 kanye namanye amazinga ohlelo lokuphathwa kwekhwalithi lomhlaba jikelele.
6. Ukwethembeka nokuqina
Ukuthembeka nokuqina kwamabhodi e-PCB yezimoto yizinkomba ezibalulekile zokukala ukusebenza kwawo. Izinto ezisezingeni eliphezulu kanye nezinqubo ezithuthukisiwe kumele zisetshenziswe ekwakhiweni nasekukhiqizeni ukuze kuqinisekiswe ukuthi ibhodi le-PCB lingaqhubeka nokusebenza kuwo wonke umjikelezo wokuphila wemoto, ikakhulukazi ngesikhathi Lapho ubhekene nomgwaqo onzima nezimo zezulu.
7. Ubungane bemvelo
Njengoba umhlaba ukunaka kakhulu ukuvikelwa kwemvelo, imboni yezimoto nayo igqugquzela ukukhiqizwa okuluhlaza kanye nentuthuko esimeme. Ukukhiqizwa kwamabhodi e-PCB e-automotive electronic kufanele futhi kucabangele izici zemvelo, njengokusebenzisa i-solder engenamthofu nezinto ezihambisana namazinga emvelo afana ne-RoHS ne-REACH.
Ukwenza ngokwezifiso amabhodi e-PCB e-automotive electronic kuyinqubo eyinkimbinkimbi futhi eqinile ehlanganisa izici eziningi zobuchwepheshe namazinga, kusukela ekukhethweni kwezinto ezibonakalayo kuye ekuklanyweni, kusukela ekuphathweni okushisayo kuya ekusebenzeni kukagesi, kuya ekuhlolweni kwesitifiketi kanye nobungane bemvelo, sonke isixhumanisi kufanele sibe izilawuli ezinembile ukuze kuqinisekiswe umkhiqizo wokugcina. ukusebenza nokuphepha. Ngokuthuthuka kobuchwepheshe kanye nesidingo semakethe, amazinga nezimfuneko zokwenza ngokwezifiso i-PCB yezimoto zizoqhubeka nokuvela ukuze zivumelane nezinguquko zesikhathi esizayo embonini yezimoto.
