Izinzuzo zezinto ezihlanganisiwe ezivame kakhulu
I-PCB yethu isebenzisa izinto ezifana ne-Regular Substrates S1000 - 2M, High - frequency series FSD255, FR - 4, kanye ne-TG170. I-S1000 - 2M inokusebenza kahle kukagesi kanye nokuzinza, i-FSD255 isebenza kahle kakhulu ekudlulisweni kwesignali yemvamisa ephezulu, i-FR - 4 inikeza ukwesekwa okuthembekile kwemishini, kanti i-TG170 iqinisekisa ukusebenza okuzinzile ezindaweni ezishisa kakhulu. Ukuhlanganiswa kwalezi zinto kwenza i-PCB ikwazi ukunciphisa ngempumelelo ukulahleka kwesignali ezinhlelweni zokusebenza zemvamisa ephezulu futhi iqinisekise ukudluliswa kwesignali okuzinzile, ihlangabezana nezidingo zamadivayisi ahlukahlukene kagesi ayinkimbinkimbi.
Umklamo wembobo eyingxenye uletha izinzuzo eziyingqayizivele kwi-PCB. Uvumela izingxenye ukuthi zixhunywe ngendlela ekhethekile. Isibonelo, kwezinye izingxenye ezixhunywe nge-plug-in ezidinga ukulungiswa kwemishini kanye nokuxhumeka kukagesi ngembobo, imbobo engxenye ingahlinzeka ngoxhumano oluzinzile futhi inciphise ingozi yokunamathela kabi. Ngesikhathi esifanayo, umklamo wembobo engxenye ungathuthukisa nokuhlelwa kwesikhala sebhodi lesifunda, okwenza imisebenzi eminingi endaweni elinganiselwe, kuthuthukiswe ukuhlanganiswa kanye nokusebenza kahle kwe-PCB, futhi kube lula ukwakheka okuncane kanye nokusebenza okuningi kwemikhiqizo kagesi.
Iinqubo yomgodi we-resin plug holeingagcwalisa ngempumelelo ama-via, ivimbele izinkinga ezifana namabhola okusoda kanye nama-short - circuits ngesikhathi sezinqubo zokukhiqiza ezilandelayo. Ngesikhathi esifanayo, imbobo ye-resin plug ingathuthukisa namandla okusebenza kwama-via futhi ithuthukise ukuthembeka okuphelele kwe-PCB. I-resin ephathwe ngokukhethekile isebenza kahle ekushiseni, iqinisekisa ukudluliswa kwesignali okuzinzile futhi igweme ukuvuza noma ukuphazamiseka kwama-via, ithuthukise ukusebenza kwe-PCB kuma-frequency aphezulu.
Ubuchwepheshe bokubhoboza emuvakuyinto evelele kakhulu kule PCB. Ngokubhoboza ngemuva, okungafuneki ngokusebenzisa izinti kungasuswa, kuncishiswe ukubonakaliswa nokulahlekelwa ngesikhathi sokudluliswa kwesignali futhi kuthuthukiswe ubuqotho besignali. Kumasekethe anemvamisa ephezulu, ikhwalithi yesignali ibaluleke kakhulu. Ubuchwepheshe bokubhoboza ngemuva bungenza ngcono indlela yokudluliselwa kwesignali ngempumelelo, kuqinisekiswe ukunemba nokuzinza kwesignali, futhi kwenze i-PCB isebenze kangcono ezimweni zohlelo lokusebenza ezifana nokudluliswa kwedatha ngesivinini esikhulu kanye nokuxhumana ngemvamisa ephezulu.
Okuvelele Kokusebenza Kwebhodi Lesekethe Yamamilimitha
