Liyini ibhodi elinezinhlangothi ezimbili ezinezendlalelo eziningi ezinohlangothi olulodwa?
Amabhodi e-PCB ahlukaniswa ngokwenani lezendlalelo zesekethe: amabhodi anohlangothi olulodwa, anamacele amabili kanye namabhodi anezingqimba eziningi.Amabhodi anezingqimba eziningi ngokuvamile amabhodi anezingqimba ezi-4 noma amabhodi anezingqimba ezi-6, futhi amabhodi anezingqimba eziningi angafinyelela izendlalelo ezingaphezu kweshumi nambili.Inezinhlobo ezintathu eziyinhloko zokuhlukanisa:
Iphaneli eyodwa: Ku-PCB eyisisekelo kakhulu, izingxenye zigxilwe ngakolunye uhlangothi, futhi izintambo zigxilwe ngakolunye uhlangothi.Ngenxa yokuthi izintambo zivela ohlangothini olulodwa kuphela, lolu hlobo lwe-PCB lubizwa ngokuthi uhlangothi olulodwa (uhlangothi olulodwa).Ngenxa yokuthi ibhodi elinohlangothi olulodwa linemikhawulo eminingi eqinile ekwakhiweni kwesifunda (ngoba kukhona uhlangothi olulodwa kuphela, i-wiring ayikwazi ukuwela futhi kufanele ibe yindlela ehlukile), ngakho-ke ama-circuits okuqala kuphela asebenzisa lolu hlobo lwebhodi.
Ibhodi elinezinhlangothi ezimbili: Lolu hlobo lwebhodi lesifunda lunezintambo ezinhlangothini zombili, kodwa ukusebenzisa izintambo ezisemaceleni amabili, kufanele kube nokuxhumana kwesifunda okufanele phakathi kwezinhlangothi zombili."Amabhuloho" phakathi kwamasekhethi anjalo abizwa ngokuthi i-vias.I-Via iyimbobo encane egcwele noma embozwe ngensimbi ku-PCB, engaxhunywa ezintanjeni nhlangothi zombili.Ngenxa yokuthi indawo yebhodi enezinhlangothi ezimbili inkulu ngokuphindwe kabili kunebhodi elinohlangothi olulodwa, futhi ngenxa yokuthi izintambo zingahlukaniswa (ingalimaza ngakolunye uhlangothi), ifaneleka kakhulu ukusetshenziswa kumasekhethi. eziyinkimbinkimbi kakhulu kunebhodi elinohlangothi olulodwa.
Ibhodi le-Multilayer: Ukuze kwandiswe indawo engakwazi ukuxhunywa izintambo, ibhodi le-multilayer lisebenzisa amabhodi ezintambo angawodwa noma anezinhlangothi ezimbili.Sebenzisa okukodwa okukabili njengongqimba lwangaphakathi, okubili okuhlangothi olulodwa njengongqimba lwangaphandle noma okubili okunezinhlangothi ezimbili njengongqimba lwangaphakathi futhi okubili okunohlangothi olulodwa njengongqimba lwangaphandle lwebhodi lesifunda eliphrintiwe.Isistimu yokumisa kanye nezinto ezibophayo ezivikelayo ngokushintshana ndawonye kanye nephethini yokuqhuba Amabhodi esekethe aphrintiwe axhumene ngokuvumelana nezimfuneko zedizayini aba amabhodi esekethe aphrintiwe anezendlalelo ezine noma ayisithupha, abuye aziwe ngokuthi amabhodi esekethe aphrintelwe izendlalelo eziningi.Inani lezendlalelo zebhodi lisho ukuthi kunezingqimba zezintambo eziningana ezizimele.Ngokuvamile inani lezendlalelo liyalingana futhi liqukethe izingqimba ezimbili ezingaphandle.Amabhodi omama amaningi anezigaba ezi-4 kuye kweziyi-8 zesakhiwo, kodwa ngokobuchwepheshe, amabhodi e-PCB anezendlalelo ezicishe zibe yi-100 angazuzwa ngokombono.Amakhompiyutha amaningi amakhulu asebenzisa amabhodi omama anezingqimba eziningi, kodwa ngenxa yokuthi lolu hlobo lwekhompiyutha lungavele luthathelwe indawo yiqoqo lamakhompiyutha amaningi ajwayelekile, amabhodi ama-super-multilayer kancane kancane awasetshenziswa.
Ngenxa yokuthi izendlalelo ku-PCB zihlanganiswe ngokuqinile, ngokuvamile akulula ukubona inombolo yangempela, kodwa uma ubhekisisa ibhodi lomama, usengayibona.
Ngokusho kwesigaba esithambile nesiqinile: ihlukaniswe ngamabhodi wesifunda ajwayelekile kanye namabhodi wesifunda aguquguqukayo.Impahla eluhlaza ye-PCB i-copper clad laminate, okuyi-substrate material yokwenza amabhodi esekethe aphrintiwe.Isetshenziselwa ukusekela izingxenye ezihlukahlukene, futhi ingafinyelela uxhumano lukagesi noma ukufakwa kukagesi phakathi kwabo.Kalula nje, i-PCB iyibhodi elincanyana elinamasekhethi ahlanganisiwe nezinye izingxenye ze-elekthronikhi.Izovela cishe kuzo zonke izisetshenziswa zikagesi.
