Imakethi ye-automotive electronics iyindawo yesithathu enkulu yokusetyenziswa kwePCBs emva kweekhompyuter kunye nonxibelelwano. Njengoko iimoto ziye zavela ngokuthe ngcembe kwiimveliso zoomatshini ngokwengqiqo yemveli zaba ziimveliso zobugcisa obuphezulu obukrelekrele, ulwazi, kunye ne-mechatronics, itekhnoloji ye-elektroniki isetyenziswe ngokubanzi kwiimoto, nokuba yinkqubo ye-injini okanye inkqubo ye-chassis, iimveliso zombane ezisetyenziswa kwiisistim zokhuseleko, iinkqubo zolwazi, kunye neenkqubo zokusingqongileyo kwimoto. Imarike yeemoto ngokucacileyo ibe yenye indawo eqaqambileyo kwimarike ye-elektroniki yabathengi. Ukuphuhliswa kwee-automotive electronics kuye kwaqhuba ngokwendalo uphuhliso lweePCB zemoto.
Kwizicelo eziphambili zanamhlanje zeePCBs, iiPCB zeemoto zikwindawo ebalulekileyo. Nangona kunjalo, ngenxa yendawo ekhethekileyo yokusebenza, ukhuseleko kunye neemfuno eziphezulu zangoku zemoto, iimfuno zayo kwi-PCB yokuthembeka kunye nokuguquguquka kokusingqongileyo ziphezulu, kunye neentlobo zobuchwepheshe be-PCB ezibandakanyekayo nazo zibanzi. Lo ngumba omkhulu kwiinkampani zePCB. Imingeni; kunye nabavelisi abafuna ukuphuhlisa imarike yePCB yeemoto, ukuqonda ngakumbi kunye nohlalutyo lwale marike intsha iyafuneka.
IiPCB zeemoto zigxininisa ukuthembeka okuphezulu kunye ne-DPPM ephantsi. Ke, ngaba inkampani yethu inengqokelela yetekhnoloji kunye namava kwimveliso ethembeke kakhulu? Ngaba iyahambelana nesikhokelo sophuhliso lwemveliso yexesha elizayo? Ngokumalunga nolawulo lwenkqubo, ngaba inokwenziwa ngokuhambelana neemfuno ze-TS16949? Ngaba ifumene i-DPPM ephantsi? Zonke ezi zifuna ukuphononongwa ngononophelo. Ukubona nje le khekhe ehendayo kunye nokungena kuyo ngobumfama kuya kubangela ingozi kwishishini ngokwalo.
Oku kulandelayo kubonelela ngenxalenye emele ezinye izenzo ezikhethekileyo kwimveliso yeenkampani ze-PCB zeemoto ngexesha lenkqubo yokuvavanya uninzi lwabalingane be-PCB ukuze kubhengezwe:
1. Indlela yokuvavanya yesibini
Abanye abavelisi be-PCB bamkela "indlela yovavanyo lwesibini" ukuphucula izinga lokufumana iibhodi ezineziphene emva kokuqhawuka kombane wokuqala we-high-voltage.
2. Inkqubo yokuvavanya ibhodi engalunganga
Bayanda abavelisi be-PCB bafake "inkqubo yokumakisha ibhodi elungileyo" kunye "nebhokisi yobungqina bempazamo yebhodi" kumatshini wokuvavanya ibhodi ukuze uphephe ngokufanelekileyo ukuvuza kwabantu. Inkqubo yokumakisha ibhodi elungileyo iphawula ibhodi yePASS evavanyiweyo kumatshini wokuvavanya, enokuthintela ngokufanelekileyo ibhodi evavanyiweyo okanye ibhodi embi ukuba igeleze ezandleni zabathengi. Ibhokisi elibi lobungqina bephutha lebhodi kukuba ngexesha lovavanyo, xa ibhodi yePASS ivavanywa, inkqubo yokuvavanya ivelisa umqondiso wokuba ibhokisi ivuliwe; ngaphandle koko, xa ibhodi embi ivavanywa, ibhokisi ivaliwe, ivumela umqhubi ukuba abeke ibhodi yesekethe evavanyiweyo ngokuchanekileyo.
3. Ukuseka inkqubo yomgangatho wePPm
Okwangoku, inkqubo yomgangatho we-PPm (i-Partspermillion, iinxalenye kwisigidi sesiphene) isetyenziswe ngokubanzi kubavelisi be-PCB. Phakathi kwabathengi abaninzi benkampani yethu, isicelo kunye neempumelelo zeHitachi ChemICal eSingapore zezona zifanele ukubhekiswa. Kumzi-mveliso, kukho abantu abangaphezu kwama-20 abanoxanduva lohlalutyo lweenkcukacha-manani lwe-intanethi ye-PCB engaqhelekanga kunye nembuyekezo engaqhelekanga ye-PCB. Ukusebenzisa indlela yokuhlalutya izibalo zenkqubo yokuvelisa i-SPC, ibhodi nganye eyaphukileyo kunye nebhodi nganye enesiphene ebuyisiwe ihlelwa kuhlalutyo lwamanani, kwaye idibaniswe ne-micro-slicing kunye nezinye izixhobo ezincedisayo ukuhlalutya apho inkqubo yokuvelisa ibhodi embi kunye nesiphako iveliswa. Ngokweziphumo zedatha yamanani, ukusombulula ngabom iingxaki kwinkqubo.
4. Indlela yokuvavanya yokuthelekisa
Abanye abathengi basebenzisa iimodeli ezimbini zeempawu ezahlukeneyo zovavanyo lokuthelekisa iibhetshi ezahlukeneyo zePCB, kwaye balandelele iPPm yeebhetshi ezihambelanayo, ukuze baqonde ukusebenza koomatshini bovavanyo ababini, kwaye emva koko ukhethe umatshini wokuvavanya ukusebenza ongcono ukuvavanya iiPCB zeemoto. .
5. Phucula iiparamitha zovavanyo
Khetha iiparameters zovavanyo eziphezulu ukufumana ngokungqongqo ezo PCB. Kuba, ukuba ukhetha i-voltage ephezulu kunye ne-threshold, yongeza inani le-high-voltage yokufunda ukuvuza, kunokuphucula izinga lokubona ibhodi enesiphene ye-PCB. Ngokomzekelo, inkampani enkulu ye-PCB yaseTaiwan e-Suzhou yasebenzisa i-300V, i-30M, kunye ne-Euro ye-20 ukuvavanya ii-PCB zeemoto.
6. Qinisekisa ngamaxesha athile iiparamitha zomatshini wokuvavanya
Emva kokusebenza kwexesha elide lomatshini wokuvavanya, ukuchasana kwangaphakathi kunye nezinye iiparitha zovavanyo ezinxulumene nazo ziya kuphambuka. Ngoko ke, kuyimfuneko ukulungelelanisa amaxesha athile iiparitha zomatshini ukuqinisekisa ukuchaneka kweeparitha zokuvavanya. Izixhobo zokuvavanya zigcinwa kwinxalenye enkulu yamashishini amakhulu e-PCB kwisiqingatha sonyaka okanye unyaka, kwaye iiparitha zokusebenza zangaphakathi zihlengahlengiswa. Ukusukela “zero defect” iiPCB zemoto ibisoloko isalathiso kwimizamo yabantu abaninzi be-PCB, kodwa ngenxa yokusikelwa umda kwezixhobo zenkqubo kunye nezinto ezikrwada, iinkampani eziphezulu ze-PCB ezili-100 ehlabathini zisahlola rhoqo iindlela. ukunciphisa iPPm.
