isicelo somkhiqizo
Cishe wonke amadivaysi e-elekthronikhi esingawabona nge-PCB eseceleni eyodwa ayikwazi ukwenza ngaphandle kwawo, kusukela kumawashi amancane e-elekthronikhi, ama-calculator, amakhompiyutha ajwayelekile, kuya kumakhompyutha amakhulu, amadivaysi e-electronic zokuxhumana, izinhlelo zezikhali zempi, inqobo nje uma kukhona izingxenye ze-elekthronikhi ezifana namasekhethi ahlanganisiwe, i-PCB isetshenziselwa ukuxhumana kukagesi phakathi kwabo. Inikeza ukusekela komshini kokuhlanganisa okuhleliwe kwezingxenye ze-elekthronikhi ezihlukahlukene njengamasekhethi ahlanganisiwe, ibona izintambo nokuxhunywa kukagesi noma ukwahlukanisa phakathi kwezingxenye ze-elekthronikhi ezihlukahlukene njengamasekhethi ahlanganisiwe, futhi inikeza izici zikagesi ezidingekayo, njenge-impedance yesici. Ukuhlinzeka ngasikhathi sinye ihluzo zemaski ye-solder ye-solder ezenzakalelayo; Nikeza izinhlamvu zokuhlonza kanye nemifanekiso ukuze kufakwe ingxenye, ihlolwe, futhi ilungiswe.
Inqubo yokukhiqiza ye-PCB ehlangothini olulodwa
I-PCB ehlangothini olulodwa: → Ibhodi eligqoke ithusi elinohlangothi olulodwa → Ukungacwayizi → (Ukuxubha, ukomiswa) → Ukubhoboza noma ukubhoboza → Ukuphrinta isikrini kwamaphethini avimbela ukucwiliswa noma kusetshenziswa ifilimu eyomile → Ukuhlola ukwelapha nokulungiswa → Ukucwiliswa kwethusi → Ukukhipha izinto ezivimbela ukubhoboza, ukomisa → Ukuxubha, ukomisa amaphethini aluhlaza okotshani → Isikrini esisetshenziswa uwoyela we-UV → Ukuphrinta isikrini kwamaphethini okumaka izinhlamvu, ukuphulukiswa kwe-UV → Ukushisa kuqala, ukubhoboza, nokubukeka → Ukuvulwa kukagesi nokuhlola isekethe emfushane → Ukuxubha Ukomisa → Ukumboza kusengaphambili ngezinsiza zokushisela nama-oxidation inhibitors (ukomisa) noma ukufutha ngethini ngomoya oshisayo ukuze kulinganiswe → ukuhlolwa kokupakishwa → ukulethwa kwemikhiqizo eqediwe.
Izici zebhodi le-PCB elinohlangothi olulodwa
Ngenxa yokunamathela okuhle kakhulu phakathi kwe-epoxy resin ne-foil yethusi, amandla okunamathela kanye nezinga lokushisa elisebenzayo le-foil yethusi kuphezulu, futhi ingacwiliswa ekufakweni kwe-solder engu-260 ℃ ngaphandle kokugwetshwa. Indwangu yengilazi ye-epoxy resin efakwe emanzini ayithinteki kangako umswakama. Izinto ezinhle kakhulu zamasekethe aphrintiwe we-ultra-high yi-copper foil polytetrafluoroethylene glass cloth laminate. Kumadivaysi e-elekthronikhi anezidingo zokunqanda ilangabi, kusetshenziswe ama-laminates ane-copper-clad-clad-clad. Umgomo ukufaka insulate yephepha noma indwangu yengilazi ene-resin engashi noma engashi, ukuze i-phenolic paper laminates ekhiqizwe nge-copper-clad, i-copper-clad epoxy paper laminates, i-copper-clad epoxy glass cloth laminates, kanye ne-copper-clad epoxy phenolic indwangu yengilazi ye-phenolic iphinde ibe ne-laminates efanayo - i-laminates ye-copper-clad ukulibala.
