Izindlela ezijwayelekile zokutholwa zebhodi le-PCB zimi kanje:
1, ukuhlolwa okubonakalayo kwebhodi le-PCB
Ngokusebenzisa ingilazi yokukhulisa noma isibonakhulu esilinganisiwe, ukuhlola okubonakalayo komsebenzisi kuyindlela evamile yokuhlola ukuze kutholwe ukuthi ingabe ibhodi lesekhethi liyalingana nokuthi kudingeka nini ukulungisa. Izinzuzo zayo eziyinhloko izindleko eziphansi zangaphambili futhi akukho ukulungiswa kokuhlolwa, kuyilapho ukonakala kwayo okuyinhloko kuyiphutha lomuntu, izindleko zesikhathi eside, ukutholwa kokukhubazeka okungaqhubeki, ubunzima bokuqoqwa kwedatha, njll. Njengamanje, ngenxa yokwanda kokukhiqizwa kwe-PCB, ukuncipha yesikhala sezintambo kanye nevolumu yengxenye ku-PCB, le ndlela iya ngokuya ingasebenzi.
2, PCB board test online
Ngokutholwa kwezakhiwo zikagesi ukuze kutholwe amaphutha okukhiqiza nokuhlola i-analogi, idijithali nezingxenye zesignali ezixubile ukuze kuqinisekiswe ukuthi ziyahlangabezana nokucaciswa, kunezindlela ezimbalwa zokuhlola ezifana nesihloli senaliti senaliti kanye nesihloli senaliti endizayo. Izinzuzo eziyinhloko izindleko eziphansi zokuhlola ibhodi ngalinye, amandla okuhlola aqinile edijithali nokusebenzayo, ukuhlolwa kwesifunda okufushane nokucacile okufushane nokuvulekile, i-firmware yokuhlela, ukumbozwa kokukhubazeka okuphezulu kanye nokulula kokuhlela. Ukungalungi okuyinhloko isidingo sokuhlola i-clamp, ukuhlela kanye nesikhathi sokulungisa iphutha, izindleko zokwenza ukulungiswa ziphezulu, futhi ubunzima bokusebenzisa bukhulu.
3, ukuhlolwa komsebenzi webhodi le-PCB
Ukuhlolwa kwesistimu esebenzayo ukusebenzisa imishini yokuhlola ekhethekile esigabeni esiphakathi nasekupheleni komugqa wokukhiqiza ukuze kwenziwe ukuhlolwa okuphelele kwamamojula asebenzayo webhodi lesifunda ukuze kuqinisekiswe ikhwalithi yebhodi lesifunda. Ukuhlola okusebenzayo kungashiwo njengomgomo wokuqala wokuhlola okuzenzakalelayo, osuselwe ebhodini elithile noma iyunithi ethile futhi ongaqedelwa ngamadivaysi ahlukahlukene. Kunezinhlobo zokuhlolwa komkhiqizo wokugcina, imodeli eqinile yakamuva, nokuhlola okustakiwe. Ukuhlola okusebenzayo ngokuvamile akuhlinzeki ngedatha ejulile efana nephinikhodi neleveli yokuxilongwa kwengxenye ukuze kulungiswe inqubo, futhi kudinga amathuluzi akhethekile kanye nezinqubo zokuhlola eziklanywe ngokukhethekile. Ukubhala izinqubo zokuhlola ezisebenzayo kuyinkimbinkimbi ngakho-ke ayifanele imigqa eminingi yokukhiqiza yebhodi.
4, ukubona okuzenzakalelayo
Okwaziwa nangokuthi ukuhlola okubukwayo okuzenzakalelayo, kusekelwe kumgomo wokubona, ukusetshenziswa okuphelele kokuhlaziywa kwesithombe, ikhompyutha nokulawula okuzenzakalelayo nobunye ubuchwepheshe, amaphutha okuhlangatshezwane nawo ekukhiqizeni ukuze kutholwe futhi kucutshungulwe, kuyindlela entsha uma kuqhathaniswa yokuqinisekisa amaphutha okukhiqiza. I-AOI ivame ukusetshenziswa ngaphambi nangemuva kokugeleza kabusha, ngaphambi kokuhlolwa kukagesi, ukuze kuthuthukiswe izinga lokukwamukela ngesikhathi sokwelashwa kukagesi noma isigaba sokuhlola ukusebenza, lapho izindleko zokulungisa amaphutha ziphansi kakhulu kunezindleko ngemva kokuhlolwa kokugcina, ngokuvamile kufika izikhathi eziyishumi.
5, ukuhlolwa kwe-X-ray okuzenzakalelayo
Ngokusebenzisa ukumuncwa okuhlukile kwezinto ezihlukene ku-X-ray, singabona ngezingxenye ezidinga ukutholwa futhi sithole amaphutha. Isetshenziselwa kakhulu ukuthola i-ultra-fine pitch kanye namabhodi esekethe okuminyana okuphezulu kakhulu kanye nokukhubazeka okufana nebhuloho, i-chip elahlekile kanye nokungaqondi kahle kahle okukhiqizwa enqubweni yomhlangano, futhi ingakwazi nokubona amaphutha angaphakathi e-IC chips isebenzisa ubuchwepheshe bayo be-tomographic imaging. Njengamanje iyona ndlela kuphela yokuhlola ikhwalithi yokushisela ye-ball grid array kanye namabhola ethini avikelwe. Izinzuzo eziyinhloko yikhono lokubona ikhwalithi yokushisela ye-BGA kanye nezingxenye ezishumekiwe, azikho izindleko zokulungisa; Ububi obuyinhloko isivinini esinensayo, izinga eliphezulu lokwehluleka, ubunzima bokuthola amajoyinti e-solder asetshenziwe kabusha, izindleko eziphezulu, kanye nesikhathi eside sokuthuthukiswa kohlelo, okuyindlela entsha yokuthola futhi edinga ukuqhutshekwa nokufundwa.
6, uhlelo lokutholwa kwe-laser
Intuthuko yakamuva kubuchwepheshe bokuhlola be-PCB. Isebenzisa i-laser beam ukuze iskene ibhodi eliphrintiwe, iqoqe yonke idatha yokulinganisa, futhi iqhathanise inani langempela lokulinganisa nevelu yomkhawulo ecushwe ngaphambilini. Lobu buchwepheshe bufakazelwe emapuletini akhanyayo, bucatshangelwa ukuhlolwa kwepuleti lokuhlanganisa, futhi bushesha ngokwanele emigqeni yokukhiqiza ngobuningi. Ukukhishwa okusheshayo, asikho isidingo sokulungisa kanye nokufinyelela okubonakalayo okungamaski kuyizinzuzo zakhona eziyinhloko; Izindleko eziphezulu zokuqala, ukunakekelwa kanye nezinkinga zokusebenzisa amaphutha ayo amakhulu.
7, ukutholwa kosayizi
Ubukhulu bokuma kwembobo, ubude nobubanzi, kanye nezinga lendawo kukalwa ngethuluzi lokulinganisa lesithombe esiyiquadratic. Njengoba i-PCB iwuhlobo oluncane, oluncane noluthambile lomkhiqizo, ukukalwa kokuxhumana kulula ukukhiqiza ukuguquguquka, okuholela esilinganisweni esingalungile, futhi ithuluzi lokulinganisa lesithombe esinezinhlangothi ezimbili selibe ithuluzi lokulinganisa lobukhulu obunembayo eliphakeme kakhulu. Ngemuva kokuthi ithuluzi lokulinganisa isithombe se-Sirui lihlelwe, lingakwazi ukubona ukukala okuzenzakalelayo, okungagcini nje ngokunemba okuphezulu kokulinganisa, kodwa futhi kunciphisa kakhulu isikhathi sokulinganisa futhi kuthuthukise ukusebenza kahle kokulinganisa.
