Imakethe ye-automotive electronics iyindawo yesithathu enkulu yokufakwa kwezicelo zama-PCB ngemuva kwamakhompyutha nokuxhumana. Njengoba izimoto ziye zavela kancane kancane emikhiqizweni eyimishini ngomqondo wendabuko zaba imikhiqizo yobuchwepheshe obuphezulu ehlakaniphile, enolwazi, kanye ne-mechatronics, ubuchwepheshe be-elekthronikhi busetshenziswe kabanzi ezimotweni, kungaba uhlelo lwenjini noma uhlelo lwe-chassis, imikhiqizo ye-elekthronikhi isetshenziswa kabanzi ezimotweni. esetshenziswa ezinhlelweni zokuphepha, izinhlelo zolwazi, kanye nezinhlelo zemvelo ezingaphakathi emotweni. Imakethe yezimoto ngokusobala isiphenduke enye indawo ekhanyayo emakethe ye-electronics yabathengi. Ukuthuthukiswa kobuchwepheshe bezimoto ngokwemvelo kuqhubekisele phambili ukuthuthukiswa kwama-PCB ezimoto.

Kuzicelo ezibalulekile zanamuhla zama-PCB, ama-PCB ezimoto athatha isikhundla esibalulekile. Nokho, ngenxa yendawo ekhethekile yokusebenza, ukuphepha kanye nezidingo eziphakeme zamanje zemoto, izidingo zayo ekuthembekeni kwe-PCB nokuvumelana nezimo zemvelo ziphezulu, futhi izinhlobo zobuchwepheshe be-PCB ezihilelekile nazo zibanzi uma kuqhathaniswa. Lokhu kuyinkinga enkulu yezinkampani ze-PCB. Izinselele; futhi kubakhiqizi abafuna ukuthuthukisa imakethe ye-PCB yezimoto, ukuqonda okwengeziwe nokuhlaziywa kwale makethe entsha kuyadingeka.

Ama-PCB ezimoto agcizelela ukwethembeka okuphezulu kanye ne-DPPM ephansi. Ngakho-ke, ingabe inkampani yethu inakho ukuqoqwa kobuchwepheshe kanye nesipiliyoni ekukhiqizeni okunokwethenjelwa okuphezulu? Ingabe iyahambisana nesiqondiso sokuthuthukiswa komkhiqizo wesikhathi esizayo? Mayelana nokulawulwa kwenqubo, kungenziwa ngokuhambisana nezidingo ze-TS16949? Ingabe isizuze i-DPPM ephansi? Konke lokhu kudinga ukucutshungulwa ngokucophelela. Ukubona nje leli khekhe elihehayo nokungena kulo ngobumpumputhe kuzodala umonakalo ebhizinisini ngokwalo.

Okulandelayo kunikeza ingxenye emele ezinye zezinqubo ezikhethekile ekukhiqizweni kwezinkampani ze-PCB zezimoto ngesikhathi senqubo yokuhlola iningi lozakwethu be-PCB ukuze bathole inkomba:

1. Indlela yokuhlola yesibili
Abanye abakhiqizi be-PCB bamukela "indlela yokuhlola yesibili" ukuze bathuthukise izinga lokuthola amabhodi angasebenzi kahle ngemva kokuphuka kokuqala kukagesi onamandla amakhulu.

2. Ibhodi elibi lohlelo lokuhlola olungenangqondo
Abakhiqizi abaningi be-PCB bafake “uhlelo oluhle lokumaka lwebhodi” kanye “nebhokisi lobufakazi bephutha lebhodi elibi” emshinini wokuhlola ibhodi lokubona ukuze kugwenywe ngempumelelo ukuvuza komuntu. Uhlelo oluhle lokumaka ibhodi luphawula ibhodi le-PASS elihloliwe lomshini wokuhlola, elingavimbela ngokuphumelelayo ibhodi elihloliwe noma ibhodi elibi ukuthi lingagelezi ezandleni zamakhasimende. Ibhokisi lobufakazi bephutha lebhodi elibi liwukuthi ngesikhathi sokuhlolwa, lapho ibhodi le-PASS lihlolwa, uhlelo lokuhlola lukhipha isignali ukuthi ibhokisi livuliwe; ngaphandle kwalokho, lapho ibhodi elibi lihlolwa, ibhokisi livaliwe, okuvumela opharetha ukuthi abeke ibhodi lesifunda elihloliwe ngendlela efanele.

3. Sungula uhlelo lwekhwalithi ye-PPm
Njengamanje, uhlelo lwekhwalithi ye-PPm (Partspermillion, izingxenye ngesigidi sesilinganiso sokukhubazeka) selusetshenziswe kabanzi kubakhiqizi be-PCB. Phakathi kwamakhasimende amaningi enkampani yethu, isicelo kanye nezimpumelelo ze-Hitachi ChemICal e-Singapore yizona ezifanele kakhulu ukubhekisela kuzo. Embonini, kunabantu abangaphezu kuka-20 abanomthwalo wemfanelo wokuhlaziya izibalo zokungajwayelekile kwekhwalithi ye-PCB eku-inthanethi kanye nezimbuyiselo ezingavamile zekhwalithi ye-PCB. Kusetshenziswa indlela yokuhlaziywa kwezibalo yenqubo yokukhiqiza ye-SPC, ibhodi ngalinye eliphukile kanye nebhodi ngalinye elinesici elibuyisiwe lihlukaniswa ukuze kuhlaziywe izibalo, futhi kuhlanganiswe nokusika okuncane namanye amathuluzi asizayo ukuze kuhlaziywe ukuthi inqubo yokukhiqiza ikhiqizwa kuphi ibhodi elibi nelingenasici. Ngokwemiphumela yedatha yezibalo, xazulula izinkinga ngenqubo.

4. Indlela yokuhlola yokuqhathanisa
Amanye amakhasimende asebenzisa amamodeli amabili emikhiqizo ehlukene ukuhlola okuqhathanisayo kwamaqoqo ahlukene e-PCB, futhi alandelela i-PPm yamaqoqo ahambisanayo, ukuze aqonde ukusebenza kwemishini emibili yokuhlola, bese ekhetha umshini wokuhlola ukusebenza ongcono ukuze ahlole ama-PCB ezimoto. .

5. Thuthukisa amapharamitha wokuhlola
Khetha amapharamitha wokuhlola aphezulu ukuze uthole ngokuqinile ama-PCB anjalo. Ngoba, uma ukhetha i-voltage ephezulu kanye ne-threshold, ukwandisa inani lokuvuza okufundeka kwe-voltage ephezulu, kungathuthukisa izinga lokutholwa kwebhodi elingasebenzi le-PCB. Isibonelo, inkampani enkulu yase-Taiwanese PCB e-Suzhou yasebenzisa i-300V, 30M, nama-Euro angu-20 ukuhlola ama-PCB ezimoto.

6. Qinisekisa ngezikhathi ezithile amapharamitha omshini wokuhlola
Ngemuva kokusebenza isikhathi eside komshini wokuhlola, ukumelana kwangaphakathi neminye imingcele yokuhlola ehlobene izophambuka. Ngakho-ke, kuyadingeka ukulungisa ngezikhathi ezithile imingcele yomshini ukuze uqinisekise ukunemba kwemingcele yokuhlola. Izinto zokuhlola zigcinwa engxenyeni enkulu yamabhizinisi amakhulu e-PCB isigamu sonyaka noma unyaka, futhi imingcele yokusebenza yangaphakathi iyalungiswa. Ukuphishekela “zero defect” PCBs ezimotweni bekulokhu kuwumhlahlandlela wemizamo yeningi labantu be-PCB, kodwa ngenxa yokulinganiselwa kwemishini yokusebenza nezinto zokusetshenziswa, izinkampani eziphezulu eziyi-100 ze-PCB emhlabeni zisahlola njalo izindlela. ukunciphisa i-PPm.
