Njira zodziwika bwino za bolodi la PCB ndi izi:
1, PCB board manual zowonera
Pogwiritsa ntchito galasi lokulitsa kapena maikulosikopu, kuyang'ana kowonekera kwa wogwiritsa ntchito ndiyo njira yakale kwambiri yowunikira kuti mudziwe ngati bolodi lozungulira likukwanira komanso pamene ntchito yokonza ikufunika. Ubwino wake waukulu ndi mtengo wotsika wakutsogolo ndipo palibe choyeserera, pomwe zovuta zake zazikulu ndi zolakwika zamunthu, mtengo wanthawi yayitali, kudziwika kosalekeza, zovuta zosonkhanitsira deta, etc. Pakali pano, chifukwa cha kuchuluka kwa kupanga kwa PCB, kuchepetsa za katayanidwe ka waya ndi voliyumu ya zigawo pa PCB, njira iyi ikukhala yosatheka.
2, PCB board pa intaneti mayeso
Kupyolera mu kuzindikira katundu wamagetsi kuti adziwe zolakwika zopanga ndi kuyesa analogi, digito ndi zigawo zosakanikirana za siginecha kuti zitsimikizire kuti zimakwaniritsa zofunikira, pali njira zingapo zoyesera monga choyesera bedi la singano ndi choyezera singano chowuluka. Ubwino waukulu ndi mtengo wotsika woyesera pa bolodi, mphamvu zoyesera za digito ndi magwiridwe antchito, kuyezetsa kwakanthawi kochepa komanso kotseguka, kuyesa kwadongosolo, kufalikira kwakukulu komanso kumasuka kwa mapulogalamu. Zoyipa zazikulu ndizofunika kuyesa nthawi yochepetsera, kukonza mapulogalamu ndi kukonza zolakwika, mtengo wopanga mawonekedwewo ndi wokwera, ndipo zovuta zogwiritsira ntchito ndizokulirapo.
3, PCB board ntchito mayeso
Kuyesa kwa machitidwe ogwirira ntchito ndikugwiritsa ntchito zida zapadera zoyeserera pakatikati ndi kumapeto kwa mzere wopanga kuti achite mayeso athunthu amitundu yogwira ntchito ya board yozungulira kuti atsimikizire mtundu wa bolodi ladera. Kuyesa kogwira ntchito kunganenedwe kuti ndiye njira yoyamba yoyesera yokha, yomwe imachokera pa bolodi kapena gawo linalake ndipo imatha kumalizidwa ndi zida zosiyanasiyana. Pali mitundu yoyesera yomaliza yazinthu, mtundu waposachedwa kwambiri, komanso kuyesa kwapang'onopang'ono. Kuyesa kogwira ntchito nthawi zambiri sikumapereka chidziwitso chakuya monga ma pini ndi magawo owunikira kuti asinthe, ndipo amafunikira zida zapadera ndi njira zoyesera zopangidwira mwapadera. Kulemba njira zoyeserera ndizovuta ndipo chifukwa chake sizoyenera mizere yambiri yopanga ma board.
4, kudziwika kokha kwa kuwala
Amatchedwanso zodziwikiratu kuona anayendera, zachokera mfundo kuwala, ntchito mabuku kusanthula fano, kompyuta ndi kulamulira basi ndi matekinoloje ena, zofooka anakumana kupanga kuzindikira ndi processing, ndi njira yatsopano kutsimikizira zolakwika kupanga. AOI imagwiritsidwa ntchito nthawi zambiri isanayambike komanso itatha, kuyesa magetsi kusanachitike, kuti apititse patsogolo mlingo wovomerezeka panthawi ya chithandizo chamagetsi kapena gawo loyesa ntchito, pamene mtengo wokonza zolakwika ndi wotsika kwambiri kuposa mtengo pambuyo pa kuyesa komaliza, nthawi zambiri mpaka kakhumi.
5, kuyesa kwa X-ray kokha
Pogwiritsa ntchito mayamwidwe osiyanasiyana a zinthu zosiyanasiyana pa X-ray, titha kuwona kudzera m'zigawo zomwe zimayenera kuzindikirika ndikupeza zolakwika. Amagwiritsidwa ntchito kwambiri kuti azindikire kukwera kwapamwamba kwambiri komanso ma board ozungulira kwambiri komanso osalimba kwambiri monga mlatho, chip chotayika komanso kusanja bwino komwe amapangidwa pokonzekera msonkhano, komanso amatha kuzindikira zolakwika zamkati za tchipisi ta IC pogwiritsa ntchito ukadaulo wake wojambula tomographic. Pakali pano ndi njira yokhayo yoyesera mtundu wa kuwotcherera kwa gululi la mpira ndi mipira ya malata yotetezedwa. Ubwino waukulu ndikutha kuzindikira mtundu wa kuwotcherera kwa BGA ndi zida zophatikizidwa, palibe mtengo wokonzekera; Zoyipa zazikuluzikulu ndikuthamanga pang'onopang'ono, kulephera kwakukulu, kulephera kuzindikira zolumikizira zomwe zidagwiritsidwanso ntchito, kukwera mtengo, komanso nthawi yayitali yopanga pulogalamu, yomwe ndi njira yatsopano yodziwira ndipo ikufunika kuphunziridwa mopitilira.
6, laser kuzindikira dongosolo
Ndi chitukuko chaposachedwa kwambiri muukadaulo woyeserera wa PCB. Imagwiritsa ntchito mtengo wa laser kusanthula bolodi losindikizidwa, kusonkhanitsa deta yonse yoyezera, ndikufanizira mtengo weniweni woyezera ndi mtengo womwe udakhazikitsidwa kale. Tekinoloje iyi yatsimikiziridwa pa mbale zowunikira, ikuganiziridwa kuti iyesedwe mbale ya msonkhano, ndipo imathamanga mokwanira kuti ipange mizere yambiri. Kutulutsa mwachangu, palibe chofunikira pakukonzekera komanso mwayi wowoneka wosapaka ndi zabwino zake zazikulu; Kukwera mtengo koyambirira, kukonza ndi kugwiritsira ntchito mavuto ndizovuta zake zazikulu.
7, kuzindikira kukula
Miyeso ya malo a dzenje, utali ndi m'lifupi, ndi digiri ya malo amayezedwa ndi chida choyezera chithunzi cha quadratic. Popeza PCB ndi yaing'ono, yopyapyala komanso yofewa, muyeso wolumikizana ndi wosavuta kupanga mapindikidwe, zomwe zimapangitsa kuti pakhale muyeso wolakwika, ndipo chida choyezera chazithunzi ziwiri chakhala chida chabwino kwambiri choyezera bwino kwambiri. Chida choyezera chithunzi cha Sirui chikapangidwa, chimatha kuzindikira kuyeza kwake, komwe sikungokhala ndi kulondola kwapamwamba, komanso kumachepetsa nthawi yoyezera ndikuwongolera kuyeza kwake.
