Intengiso ye-elektroniki yeemoto yindawo yesithathu ngobukhulu yokwenza isicelo PCB emva kweekhompyuter kunye nonxibelelwano. Ngeemoto ezivela kwiimveliso zemveli zoomatshini, indaleko, ethe chu yaphuhliswa yaba kukuqonda, ulwazi, ukudityaniswa koomatshini kunye nombane weemveliso zetekhnoloji ephezulu, ubuchwepheshe be-elektroniki busetyenziswa ngokubanzi emotweni, nokuba yinkqubo ye-injini, okanye inkqubo ye-chassis, inkqubo yokhuseleko, ulwazi Inkqubo, imeko-bume yendawo yangaphakathi zihlala zamkelwa njengemveliso ye-elektroniki. Ngokucacileyo, imarike yeemoto iye yaba yenye indawo eqaqambileyo kwintengiso yabathengi ye-elektroniki. Uphuhliso lwee-elektroniki zeemoto luqhube ngokwendalo ukukhula kwePCB yemoto.

Kule PCB into yesicelo esingundoqo sento yanamhlanje, i-automobile PCB ithatha indawo ebalulekileyo. Nangona kunjalo, ngenxa yendawo yokusebenza ekhethekileyo, ukhuseleko, imeko yangoku ephezulu kunye nezinye iimfuno zeemoto, baneemfuno eziphezulu ekuthembekeni kwe-PCB kunye nokuziqhelanisa nokusingqongileyo, kwaye kubandakanya uluhlu olubanzi lweentlobo zobuchwephesha be-PCB, olucelomngeni kumashishini e-PCB. Kubavelisi abafuna ukuphuhlisa intengiso ye-PCB yemoto, kufuneka benze ukuqonda ngakumbi kunye nohlalutyo lwentengiso entsha.

I-PCB yezeMoto igxininise ngokukodwa ekuthembekeni okuphezulu nakwi-DPPM esezantsi. Ke, ngaba inkampani yethu inetekhnoloji kunye namava kwimveliso ethembekileyo ephezulu? Ngaba iyahambelana nokhokelo lophuhliso lweemveliso ezizayo? Kulawulo lwenkqubo, ngaba unokwenza ngokweemfuno ze-TS16949? Ngaba iDPPM esezantsi ifezekisiwe? Zonke ezi zinto kufuneka ziphononongwe ngononophelo, jonga nje ikeyiki enokuhenda kwaye ungene ngokungaboni, ziya kuzisa ingozi kwishishini ngokwalo.

Ungakuphucula njani ukuthembeka kwePCB yemoto

Oku kulandelayo kubonelela ngeendlela ezithile ezimeleyo zabavelisi be-PCB yemoto kwinkqubo yovavanyo loogxa be-PCB ngokubanzi ukuze babhekiswe kuyo:

1. Indlela yesibini yovavanyo

Abanye abavelisi be-PCB bamkela “indlela yesibini yovavanyo” ukuphucula izinga lokufumana isiphene emva kokuphazamiseka kwamandla ombane wokuqala.

2. Ibhodi engalunganga yovavanyo lokuhlala

Ngakumbi nangakumbi abavelisi be-PCB bafake “inkqubo yokumakisha yebhodi elungileyo” kunye “nebhokisi ebubungqina bebhodi engalunganga” kumatshini wokuvavanya ibhodi yokujonga ukuthintela ukuvuza okungafunekiyo. Inkqubo yokumakisha yeplate elungileyo iphawula ipleyiti ye-PASS evavanyiweyo kumatshini wovavanyo, enokuthintela ngokufanelekileyo ipleyiti evavanyiweyo okanye ipleyiti embi ekubalekeni kuye kumthengi. Ibhokisi enobungqina bebhodi embi luphawu lokuvulwa kwebhokisi yenkqubo yovavanyo xa ibhodi ye-PASS ivavanywa kwinkqubo yovavanyo. Endaweni yokuba xa kuvavanywa ibhodi embi, ibhokisi iyavalwa, ivumele umqhubi ukuba abeke ngokufanelekileyo ibhodi evavanyiweyo.

3. Ukuseka inkqubo esemgangathweni ye-PPm

Okwangoku i-PPm (i-defect rate permillion) inkqubo esemgangathweni isetyenziswa kakhulu kubavelisi be-PCB. Phakathi kwabathengi abaninzi benkampani yethu, iHitachiChemICal eSingapore yeyona ndawo ifanelekileyo ekubhekiswa kuyo kwisicelo sayo kunye neziphumo ezifunyenweyo. Kukho abantu abangaphezulu kwama-20 kumzi-mveliso abanoxanduva lokuhlalutya ubalo lwezinto ezingaqhelekanga ezisemgangathweni zePCB kunye nomgangatho wePCB wokungaqhelekanga obuyileyo. Inkqubo yokuvelisa inkqubo ye-SPC yohlalutyo yayisetyenziselwa ukwahlula ibhodi nganye engalunganga kwaye nganye ibuyise ibhodi enesiphene kuhlalutyo lweenkcukacha-manani, kwaye idityaniswe nesilayidi esincinci kunye nezinye izixhobo ezincedisayo zokuhlalutya ukuba yeyiphi inkqubo yemveliso evelisa ibhodi engalunganga nengalunganga. Ngokweziphumo zeenkcukacha-manani, sombulula iingxaki kwinkqubo.

4. Uvavanyo lokuthelekisa

Abanye abathengi basebenzise iintlobo ezimbini ezahlukeneyo zeemodeli zePCB kwiibhetshi ezahlukeneyo zovavanyo lokuthelekisa, kwaye balanda i-PPm yeebhetshi ezihambelanayo, ukuze baqonde ukusebenza koomatshini bovavanyo ababini, ukuze ukhethe umatshini wovavanyo kunye nokusebenza okungcono ukuvavanya iimoto I-PCB.

5. Ukuphucula iiparameter zovavanyo

Khetha iparameter yovavanyo oluphezulu ukuze ulufumane ngokungqongqo olu hlobo lwe-PCB, kuba ukuba ukhetha amandla ombane aphezulu kunye nomda, yonyusa inani levolthi ephezulu yokufunda ukuvuza, kunokuphucula ukubonwa kwebhodi yesiphene sePCB. Umzekelo, inkampani enkulu ye-PCB exhaswa yi-Taiwan eSuzhou isebenzisa i-300V, 30M kunye ne-20 Euro ukuvavanya i-PCB yemoto.

6. Jonga iiparameter zovavanyo rhoqo

Emva kokusebenza kwexesha elide kumatshini wovavanyo, uxhathiso lwangaphakathi kunye nezinye iiparameter zovavanyo ezinxulumene nazo ziya kutenxa. Ke ngoko, kuyafuneka ukuba uhlengahlengise iiparameter zoomatshini rhoqo ukuqinisekisa ukuchaneka kweeparameter zovavanyo. Izixhobo zovavanyo zigcinwa kwaye iiparameter zangaphakathi zisebenza zilungelelaniswe kwisiqingatha sonyaka okanye unyaka omnye kwinani elikhulu lamashishini e-PCB. Ukufuna “zero isiphene” imoto PCB bekusoloko ulwalathiso iinzame PCB abantu, kodwa ngenxa yokusikelwa umda kwezixhobo processing, izinto ekrwada kunye nezinye iinkalo, ukuza kuthi ga ngoku phezulu 100 amabhizinisi PCB nangoku nangoku ukuhlola iindlela ukunciphisa PPm.
