Ibhodi yesekethe eprintiweyo (PCB) yibhodi ebhityileyo eyenziwe kwi-fiberglass, i-epoxy ehlanganisiweyo, okanye ezinye izinto ezinqabileyo.PCBs zifumaneka kumacandelo ezahlukeneyo zombane kunye ne-elektroniki ezifana beepers, radios, radars, iinkqubo zekhompyutha, njalo njalo iintlobo ezahlukeneyo PCBs zisetyenziswa ngokusekelwe izicelo.Zeziphi iintlobo ezahlukeneyo zePCBs?Funda ukuze wazi.Zeziphi iindidi ezahlukeneyo zeePCBs?IiPCB zihlala ...
- Iibhodi zeSekethe eziprintiweyo Ukwenziwa kokwenziwa
Ukuba uyazibuza ukuba zeziphi kanye iiBhodi zeSekethe eziShicileleyo (iiPCB) kwaye zenziwa njani, awuwedwa.Abantu abaninzi banokuqonda okungacacanga "kweeBhodi zeSekethe", kodwa eneneni abazizo iingcali xa kufikwa ekukwazini ukucacisa ukuba yintoni iBhodi yeSekethe eShicileleyo.IiPCB zidla ngokusetyenziselwa ukuxhasa kunye nokudibanisa ngombane izinto eziqhagamshelweyo ze-elektroniki ebhodini.Ezinye iimviwo...
- Isalathiso sokuthelekisa sokulandelela sePCB
Ukuxhatshazwa kokulandelela i-laminate ye-copper clad ngokuqhelekileyo ibonakaliswe ngesalathisi sokuthelekisa (CTI).Phakathi kweempawu ezininzi ze-laminates ezifakwe ubhedu (i-laminates ye-copper clad for short), ukumelana nokulandelela, njengesalathisi esibalulekileyo sokhuseleko kunye nokuthembeka, kuye kwanda ukuxatyiswa ngabayili bebhodi yesekethe ye-PCB kunye nabavelisi bebhodi yesekethe.Ixabiso le-CTI livavanywa ngokuhambelana ne ...
- Igridi yobhedu, ubhedu oluqinileyo.Eyiphi?
Yintoni ukutyabeka kobhedu?Okubizwa ngokuba kuthululwe ubhedu kukusebenzisa indawo engasetyenziswanga kwi-PCB njengendawo yesalathiso uze uyigcwalise ngobhedu oluqinileyo.Ezi ndawo zobhedu zikwabizwa ngokuba kukuzaliswa kobhedu.Ukubaluleka kokugubungela ubhedu kukunciphisa ukunyanzeliswa kocingo lomhlaba kunye nokuphucula amandla okuthintela ukuphazamiseka;ukunciphisa ukuhla kwamandla ombane kunye nokuphucula ukusebenza kakuhle konikezelo lwamandla;ukuba...
- Ulawulwa njani iphepha lebhodi yesekethe
I-Warping yebhodi yesekethe yebhetri iya kubangela ukubekwa okungachanekanga kwamacandelo;xa ibhodi igobile kwi-SMT, THT, izikhonkwane zecandelo ziya kuba zingaqhelekanga, eziza kuzisa ubunzima obuninzi kwindibano kunye nomsebenzi wofakelo.IPC-6012, SMB-SMT Iibhodi zeesekethe eziprintiweyo zine-warpage ephezulu okanye i-twist ye-0.75%, kunye nezinye iibhodi ngokubanzi azidluli kwi-1.5%;iphepha lemfazwe elivumelekileyo (kabini...
- Kutheni ibhodi yesekethe eprintiweyo idinga ulawulo lwe-impedance?
Kutheni ibhodi yesekethe eprintiweyo idinga ulawulo lwe-impedance?Kumgca wesiginali yothumelo yesixhobo sombane, ukuxhathisa okufunyenweyo xa isiginali ye-frequency ephezulu okanye i-electromagnetic wave propagate ibizwa ngokuba yi-impedance.Kutheni le nto iibhodi zePCB kufuneka zingasebenzi ngexesha lenkqubo yokwenziwa komzi-mveliso webhodi yesekethe?Makhe sihlalutye kwezi zizathu zine zilandelayo: 1. Ibhodi yesekethe yePCB ye ...
- Kutheni uninzi lweebhodi zeesekethe ezinamanani amaninzi zingamaleko alinganayo?
Kukho iibhodi zeesekethe ezinecala elinye, elinamacala amabini kunye ne-multi-layer.Inani leebhodi ze-multi-layer alikhawulelwanga.Ngoku kukho ngaphezu kwe-100-layer PCBs.IiPCBs eziqhelekileyo ezinomaleko obuninzi zine umaleko kunye neebhodi ezintandathu.Ke kutheni abantu benombuzo othi "Kutheni iibhodi zePCB ezininzi zingamanani alinganayo? Xa sithetha ngokuthelekisekayo, iiPCB ezinamanani alinganayo zineePCB ezingaphaya kwamanani angaqhelekanga, ...
