Imakethe ye-elekthronikhi yezimoto iyindawo yesithathu ngobukhulu yokufaka isicelo PCB ngemuva kwamakhompyutha nokuxhumana. Izimoto ezivela kwimikhiqizo yendabuko yemishini, ukuziphendukela kwemvelo, yathuthukiswa kancane kancane yaba ukuhlanganiswa okukhaliphile, ukwaziswa, ukuhlanganiswa kwemishini kagesi nemikhiqizo ephezulu, ubuchwepheshe be-elekthronikhi busetshenziswa kabanzi emotweni, noma ngabe uhlelo lwenjini, noma uhlelo lwe-chassis, uhlelo lokuphepha, imininingwane system, uhlelo lwezemvelo lwangaphakathi luhlala luyimikhiqizo eyamukelwa ngogesi. Ngokusobala, imakethe yezimoto isiphenduke enye indawo ekhanyayo emakethe yabathengi ngogesi. Ukuthuthukiswa kwe-elekthronikhi yezimoto ngokwemvelo kuqhube ukuthuthukiswa kwe-PCB yezimoto.

Esikhathini sanamuhla se-PCB key application object, imoto ye-PCB ithatha isikhundla esibalulekile. Kodwa-ke, ngenxa yendawo yokusebenza ekhethekile, ukuphepha, izidingo zamanje eziphakeme nezinye izidingo zezimoto, zinezidingo eziphezulu ekuthembekeni kwe-PCB nasekuguquguqukeni kwemvelo, futhi zibandakanya izinhlobo ezahlukahlukene zobuchwepheshe be-PCB, okuyinselelo kumabhizinisi e-PCB. Kubakhiqizi abafuna ukuthuthukisa imakethe ye-PCB yezimoto, badinga ukwenza ukuqonda okwengeziwe nokuhlaziywa kwale makethe entsha.

I-PCB Yezimoto inokugcizelelwa okukhethekile ekuthembekeni okuphezulu nase-DPPM ephansi. Ngemuva kwalokho, inkampani yethu inabo yini ubuchwepheshe kanye nesipiliyoni ekukhiqizeni okuthembekile okuphezulu? Ngabe iyahambisana nesiqondisi sangaphambilini sokuthuthukiswa komkhiqizo? Ekulawuleni inqubo, ungenza ngokuya ngezidingo ze-TS16949? Ngabe iDPPM ephansi izuziwe? Konke lokhu kudinga ukuhlolwa ngokucophelela, bheka nje leli khekhe elilingayo bese ungena ungaboni, kuzolimaza ibhizinisi uqobo.

Ungakuthuthukisa kanjani ukuthembeka kwe-PCB yemoto

Okulandelayo kunikeza imikhuba ethile emele yabakhiqizi be-PCB yezimoto kunqubo yokuhlola ozakwabo be-PCB jikelele ukuze kubhekwe kubo:

1. Indlela yesibili yokuhlola

Abanye abakhiqizi be-PCB basebenzisa “indlela yesibili yokuhlola” ukwenza ngcono izinga lokuthola isici ngemuva kokonakala kwamandla kagesi okuqala.

2. Uhlelo olubi lokuhlola ukuhlala kwebhodi elingalungile

Bayanda abakhiqizi be-PCB abafake “uhlelo lokumaka ibhodi elihle” kanye “nebhodi elibi lokufaka iphutha” ebhodini lokuhlola umshini wokuhlola ukugwema ukuvuza okufakelwayo. Uhlelo oluhle lokumaka ipuleti lumaka ipuleti le-PASS elihloliwe lomshini wokuhlola, elingavimba ngempumelelo ipuleti elihloliwe noma ipuleti elibi ukuba lingagobhozi liye kukhasimende. Ibhokisi lobufakazi bephutha lebhodi elibi liyisiginali yokuvulwa kokukhishwa kwebhokisi ngohlelo lokuhlola lapho ibhodi le-PASS lihlolwe kwinqubo yokuhlola. Esikhundleni salokho, lapho ibhodi elibi lihlolwe, ibhokisi liyavalwa, livumele opharetha ukuthi abeke kahle ibhodi elihloliwe.

3. Sungula uhlelo lwekhwalithi ye-PPm

Okwamanje i-PPm (defect rate permillion) uhlelo lwekhwalithi lusetshenziswa kakhulu kubakhiqizi be-PCB. Phakathi kwamakhasimende amaningi enkampani yethu, iHitachiChemICal eSingapore iyona efaneleke kakhulu ukubhekiswa ekusetshenzisweni kwayo nemiphumela etholakele. Kunabantu abangaphezu kuka-20 efektri ababhekele ukuhlaziywa kwezibalo kwe-inthanethi yekhwalithi ye-PCB nokungajwayelekile kwekhwalithi ye-PCB. Inqubo yokukhiqiza yokuhlaziya ye-SPC yasetshenziselwa ukuhlukanisa ibhodi ngalinye elibi futhi ngalinye labuya nebhodi elingalungile lokuhlaziywa kwezibalo, futhi lihlanganiswe ne-micro-slice namanye amathuluzi asizayo wokuhlaziya ukuthi iyiphi inqubo yokukhiqiza ekhiqiza ibhodi elibi nelingalungile. Ngokuya ngemininingwane yezibalo, sombulula izinkinga ngenqubo.

4. Ukuhlolwa kokuqhathanisa

Amanye amakhasimende asebenzise izinhlobo ezimbili ezahlukahlukene zamamodeli we-PCB ngamaqoqo ahlukahlukene wokuhlola ukuqhathanisa, futhi alandela i-PPm yamaqoqo ahambisanayo, ukuze aqonde ukusebenza kwemishini emibili yokuhlola, ukuze akhethe umshini wokuhlola osebenza kangcono ukuhlola izimoto I-PCB.

5. Thuthukisa imingcele yokuhlola

Khetha amapharamitha wokuhlola aphakeme ukuthola lolu hlobo lwe-PCB, ngoba uma ukhetha i-voltage ephakeme kanye nomkhawulo, khulisa inani lamandla aphezulu okufunda ukuvuza, kungathuthukisa izinga lokutholwa kwe-PCB defect board. Isibonelo, inkampani enkulu ye-PCB exhaswa yiTaiwan eSuzhou isebenzisa i-300V, 30M ne-20 Euro ukuhlola i-PCB yezimoto.

6. Hlola imingcele yemishini yokuhlola njalo

Ngemuva kokusebenza kwesikhathi eside komshini wokuhlola, ukumelana kwangaphakathi namanye amapharamitha wokuhlola ahlobene azophambuka. Ngakho-ke, kuyadingeka ukuthi ulungise imingcele yemishini njalo ukuqinisekisa ukunemba kwamapharamitha wokuhlola. Imishini yokuhlola inakekelwa futhi nemingcele yokusebenza kwangaphakathi iyalungiswa phakathi nengxenye yonyaka noma unyaka owodwa kwinani elikhulu lamabhizinisi e-PCB. Ukuphishekela “i-zero defect” yezimoto ze-PCB bekulokhu kuyisiqondiso semizamo yabantu be-PCB, kepha ngenxa yemikhawulo yokusebenza kwemishini, izinto zokusetshenziswa nezinye izinto, kuze kube manje amabhizinisi aphezulu e-100 e-PCB asacubungula izindlela zokunciphisa i-PPm.
