I-PCB isifinyezo sebhodi lesifunda eliphrintiwe ngesiNgisi. Amasekhethi aphrintiwe ajwayele ukubizwa ngokuthi amaphethini e-conductive enziwe ngamasekhethi aphrintiwe, izingxenye eziphrintiwe, noma inhlanganisela yakho kokubili, ngokusekelwe kumiklamo enqunywe kusengaphambili ezintweni zokuvikela. Iphethini yokuqhuba ehlinzeka ngoxhumano lukagesi phakathi kwezingxenye ku-substrate evikelayo ibizwa ngokuthi isekethe ephrintiwe. Ngale ndlela, izifunda eziphrintiwe noma amabhodi aqediwe amasekethe aphrintiwe abizwa ngokuthi amabhodi wesifunda aphrintiwe, aziwa nangokuthi amabhodi aphrintiwe noma amabhodi wesifunda aphrintiwe. Ku-PCB eyisisekelo kakhulu, izingxenye zigxilwe ngakolunye uhlangothi futhi izintambo zigxilwe ngakolunye uhlangothi. Ngenxa yokuthi izintambo zivela ohlangothini olulodwa kuphela, lolu hlobo lwe-PCB silubiza nge-PCB ehlangothini olulodwa. Ngenxa yokuthi ama-PCB anohlangothi olulodwa anemikhawulo eminingi eqinile ekwakhiweni kwesekethe, njengoba enohlangothi olulodwa kuphela, izintambo azikwazi ukuhlangana futhi kufanele zihanjiswe ngokuzimela.

I-Flexible PCB isetshenziswe kabanzi emakethe futhi isiwumkhiqizo obaluleke kakhulu embonini yezogesi. Ingakwazi ukuzivumelanisa nezinhlelo zokusebenza ezihlukahlukene zama-PCB aguquguqukayo, njengamadivayisi agqokekayo, izitho zokwenziwa, amathuluzi ezokwelapha, amamojula e-RFID, njll. I-PCB eguquguqukayo eqinile ithatha indawo ye-PCB eqinile, eyenziwe ngezinto ze-PCB kodwa enezici ezigotshwayo. Inhlanganisela ye-PCB eqinile futhi eguquguqukayo isetshenziselwa kakhulu omakhalekhukhwini nemikhiqizo egqokekayo. Womabili ama-PCB avumelana nezimo futhi aqinile ahlinzeka ngemiklamo eqinile enokuvumelana nezimo okwengeziwe ukuhambisa noma ukunyakazisa izingxenye zomkhiqizo.

Ama-PCB aqinile aguquguqukayo angagotshwa, agoqwe, noma agoqwe, bese ahlanganiswe emikhiqizweni ehlukahlukene. Banikeza ukusebenziseka kalula, ukuguquguquka, nokuhamba kwamadivayisi aphathekayo. Kubandakanya amakhadi okunweba namabhethri kumakhompyutha aphathekayo noma amakhompuyutha edeskithophu. I-PCB eguquguquka kancane ingagotshwa noma igotshwe, kodwa ayiguquguquki njengebhodi elihlanganisiwe eliguquguqukayo. Futhi ayisisombululo esisebenzayo sedivayisi ephathekayo ngoba ayidingi ukuxhumeka okuqinile ezindaweni ezinethrafikhi ephezulu yabahamba ngezinyawo, njengoba ingagoba ngaphandle kokuphuka noma ukuhlukana. Lokhu okuthunyelwe kwebhulogi kuzongena ekusetshenzisweni okuhlukahlukene kwe-PCB eguquguqukayo eqinile kanye nomklamo we-PCB oguquguquka kancane.

Ibhodi Lesifunda Eliphrintiwe (PCB), elaziwa nangokuthi Ibhodi Lesifunda Eliphrintiwe noma Ibhodi Lesifunda Eliphrintiwe. Amabhodi aphrintiwe we-Multilayer abhekisela kumabhodi aphrintiwe anezendlalelo ezingaphezu kwezimbili, ezakhiwe izintambo ezixhumayo ezingqimbeni eziningana ze-insulating substrates nama-solder pads asetshenziselwa ukuhlanganisa nokushisela izingxenye ze-electronic. Abagcini nje ngokuba nomsebenzi wokuqhuba izifunda zesendlalelo ngasinye, kodwa futhi banomsebenzi wokubambisana.

Ibhodi le-PCB lezendlalelo eziningi libhekisela ebhodini lesekethe elinezingqimba eziningi elisetshenziswa emikhiqizweni kagesi, esebenzisa amabhodi ezintambo amaningi anezinhlangothi ezimbili. Ibhodi lesifunda eliphrintiwe elisebenzisa ungqimba lwangaphakathi olunezinhlangothi ezimbili, izendlalelo zangaphandle ezimbili ezinohlangothi olulodwa, noma izendlalelo zangaphakathi ezinohlangothi olukabili, nezingqimba ezimbili zangaphandle ezinohlangothi olulodwa, futhi lixhunywe nemifanekiso eqhubayo ngokuya ngezidingo zedizayini ngezinhlelo zokubeka indawo nezinto zokubopha ezivikelayo, liba yibhodi lesifunda eliphrintiwe elinezingqimba ezine noma eziyisithupha, elaziwa nangokuthi ibhodi lesifunda elinezingqimba eziningi.

Isisekelo se-insulation sensimbi sakhiwe ungqimba oluyisisekelo lwensimbi, ungqimba olufakwa ngaphakathi, kanye nongqimba lwesekethe olugqoke ithusi. Kuyinsimbi yebhodi lesekethe yensimbi eyingxenye yezingxenye ezijwayelekile ze-elekthronikhi, ehlanganisa ungqimba olushisayo, ipuleti lensimbi, nefoil yensimbi. Ine-conductivity kazibuthe ekhethekile, i-heat dissipation enhle kakhulu, amandla aphezulu emishini, nokusebenza okuhle kokucubungula.

I-substrate ye-insulation ye-metal yakhiwe ungqimba lwe-metal substrate, ungqimba lokufakwa kwe-insulation, kanye nongqimba lwesekethe olugqoke ithusi. Ungqimba olungaphezulu luyingqimba yesekethe ye-copper clad, ekuqaleni equkethe ungqimba lwethusi. Ngokwezidingo zokuxhunywa kukagesi, isekethe ingagqwala ibe yisekethe edingekayo. I-transistor core yamandla, i-chip control chip, njll. ingadayiswa ngokuqondile kungqimba lwesekethe ye-copper clad. Ukuze kube lula ukushisela nokuvimbela i-oxidation, i-solder pad ihlanganiswe ne-Ti, Pt, Cu, Au namanye amafilimu amancane egolide, anobukhulu obuyi-35, 50, 70105140 microns; Isendlalelo esimaphakathi siwungqimba ophakathi nendawo ovikelayo, ngokuvamile owenziwe ngendwangu yendwangu yengilazi ye-epoxy ene-thermal conductivity, i-epoxy resin, noma ifilimu ye-organic dielectric egcwele izinto zobumba. Ubukhulu bayo buhlukaniswe ngemininingwane emine: 50, 75, 100, 150 microns.

Ibhodi le-PCB eliyifrikhwensi ephezulu libhekisela ohlotsheni olukhethekile lwebhodi lesifunda elinefrikhwensi ye-electromagnetic, esetshenziswa emkhakheni wefrikhwensi ephezulu (imvamisa enkulu kuno-300MHz noma ubude begagasi obungaphansi kwemitha elingu-1) kanye ne-microwave (imvamisa enkulu kune-3GHz noma ubude begagasi obungaphansi kwamamitha angu-0.1). Kuyibhodi lesifunda elikhiqizwe ebhodini le-microwave substrate yethusi lisebenzisa izinqubo ezithile zokukhiqiza ibhodi lesifunda eliqinile noma izindlela ezikhethekile zokucubungula.

Ingxenye ye-PCB yethusi esindayo iyingxenye ekhulayo yokukhiqiza kwethu. Ukuze sisekele le ngxenye ebalulekile, sakha ubudlelwano obunesikhathi eside nezimboni ezimbalwa ezikhethwe ngokucophelela enqubweni yethu yokufuna.
