Iibhodi zeSekethe eziShicileleyo kwicala elinye

I-PCB sisishunqulelo sebhodi yesekethe eprintiweyo ngesiNgesi. Iisekethe eziprintiweyo zidla ngokubizwa ngokuba ziipateni zokuqhuba ezenziwe ngeesekethe eziprintiweyo, iikhomponenti eziprintiweyo, okanye indibaniselwano yezi zimbini, ngokusekwe kuyilo olumiselwe kwangaphambili kwizinto zokugquma. Ipatheni yokuqhuba enika uxhulumaniso lombane phakathi kwamacandelo kwi-substrate ye-insulating ibizwa ngokuba yisekethe eprintiweyo. Ngale ndlela, iisekethe eziprintiweyo okanye iibhodi ezigqityiweyo zeesekethe eziprintiweyo zibizwa ngokuba ziibhodi zeesekethe eziprintiweyo, ezaziwa ngokuba ziibhodi eziprintiweyo okanye iibhodi zeesekethe eziprintiweyo. Kwi-PCB esisiseko, iindawo zigxininiswe kwelinye icala kwaye iingcingo zigxininiswe kwelinye icala. Kuba iingcingo zivela kwicala elinye kuphela, silubiza olu hlobo lwePCB ngokuba yiPCB esecaleni elinye. Ngenxa yokuba ii-PCB ezisecaleni zinemida emininzi engqongqo kuyilo lwesekethe, njengoko zinecala elinye kuphela, i-wiring ayikwazi ukunqumla kwaye kufuneka ihanjiswe ngokuzimeleyo.

isicelo imveliso

Phantse zonke izixhobo zombane esizibonayo ngePCB enecala elinye ayikwazi ukwenza ngaphandle kwayo, ukusuka kwiiwotshi ezincinci zombane, izixhobo zokubala, iikhompyuter zenjongo jikelele, ukuya kwiikhompyuter ezinkulu, izixhobo zonxibelelwano zombane, iinkqubo zezixhobo zomkhosi, okoko nje kukho amacandelo e-elektroniki afana neesekethe ezidibeneyo, iPCB isetyenziselwa ukunxibelelana kombane phakathi kwabo. Ibonelela ngenkxaso yomatshini kwindibano emiselweyo yamacandelo ahlukeneyo e-elektroniki afana neesekethe ezidibeneyo, iqonda iingcingo kunye noqhagamshelo lombane okanye ukugquma phakathi kwamacandelo ahlukeneyo e-elektroniki afana neesekethe ezidibeneyo, kwaye ibonelela ngeempawu zombane ezifunekayo, ezifana ne-impedance yeempawu. Kwangaxeshanye ukubonelela ngemizobo yemaski ye-solder yokuthengisa ngokuzenzekelayo; Ukubonelela ngeempawu zokuchongwa kunye nemizobo yokufakwa kwecandelo, ukuhlolwa kunye nokugcinwa.

Inkqubo yemveliso yePCB enecala elinye

IPCB enecala elinye: → ibhodi enecala elinye yobhedu → Ukungaqhwala → (Ukubrasha, ukomiswa) → Ukugrumba okanye ukugqobhoza → Ukuprintwa kwescreen seepateni ezichasayo okanye kusetyenziswa ifilim eyomileyo → Uhlolo lokunyanga kunye nokulungiswa → Ukukrolwa kobhedu → Ukususa izinto ezithintela ukurhabula, ukomisa → Ukubrasha, ukomisa iipateni ze-UV ezisetyenziswayo → Ukuprintwa kwescreen seepateni zokuphawula iimpawu, ukunyangwa kweUV → Ukufudumeza kwangaphambili, ukubethelwa ngenqindi, kunye nenkangeleko → Ukuvulwa kombane kunye novavanyo lwesekethe emfutshane → Ukomisa ibrashi → ukuqatywa kwangaphambili ngezinto zokuwelda kunye nezithinteli zeoxidation (ukomisa) okanye ukutshiza ngetoti ngomoya oshushu ukulungiselela ukulinganisa → ukuhlolwa kokupakishwa → ukuhanjiswa kweemveliso ezigqityiweyo.

Iimpawu zebhodi yePCB esecaleni

Ngenxa yokuncamathela okugqwesileyo phakathi kwe-epoxy resin kunye nefoyile yobhedu, amandla okuncamathela kunye nobushushu bokusebenza befoyile yobhedu buphezulu, kwaye inokuntywiliselwa kwi-soldering kwi-260 ℃ ngaphandle kogwebu. I-epoxy resin efakwe ngelaphu leglasi elaminates azichatshazelwa kancinci kukufuma. Eyona imathiriyeli igqwesileyo kwi-ultra-high frequency printed circuits yicopper foil polytetrafluoroethylene glass cloth laminate. Kwizixhobo zombane ezineemfuno zokunqanda amadangatye, i-laminates ene-flame-retardant copper-clad nayo isetyenziswa. Umgaqo-siseko kukufakela insulate yephepha okanye ilaphu leglasi elinentlaka enokutsha okanye engatshiyo, ukwenzela ukuba iphepha lephenolic eliveliswe ngephenolic laminates, icopper-clad epoxy paper laminates, copper-clad epoxy glass cloth laminates, kunye necopper-clad epoxy phenolic glass cloth laminates iphinde ibe nelaminates yobhedu efanayo. ukusilela.
