Izimbobo zivuliwePCBzingahlukaniswa zibe plated ngokusebenzisa izimbobo (PTH) futhi non-plated ngokusebenzisa izimbobo (NPTH) ngokusekelwe uma kukhona ugesi ezixhunywe.
I-Plated through hole (PTH) isho imbobo enensimbi ezindongeni zayo, engafinyelela ukuxhumana kukagesi phakathi kwamaphethini okuqhuba ungqimba olungaphakathi, ungqimba olungaphandle, noma kokubili kwe-PCB.Ubukhulu bayo bunqunywa ubukhulu bembobo ebhoboziwe kanye nobukhulu besendlalelo esicwecwe.
I-Non-plated through holes (NPTH) yizimbobo ezingabambi iqhaza ekuxhumekeni kukagesi kwe-PCB, eyaziwa nangokuthi izimbobo ezingenansimbi.Ngokwesendlalelo imbobo engena ngayo ku-PCB, imigodi ingahlukaniswa njenge-out-hole, igqitshwe nge/imbobo, futhi ingaboni nge/imbobo.
Ngezimbobo zingena kuyo yonke i-PCB futhi zingasetshenziselwa ukuxhumana kwangaphakathi kanye/noma ukubeka nokukhweza izingxenye.Phakathi kwazo, izimbobo ezisetshenziselwa ukulungisa kanye/noma ukuxhumeka kukagesi namatheminali ezingxenye (okuhlanganisa izikhonkwane nezintambo) ku-PCB zibizwa ngokuthi izimbobo zezingxenye.Izimbobo ezipthiwe ezisetshenziselwa ukuxhumeka kwezingqimba zangaphakathi kodwa ngaphandle kwemikhondo yengxenye yokukhwezwa noma ezinye izinto zokuqinisa zibizwa ngezimbobo.Ngokuyinhloko kunezinjongo ezimbili zokubhoboza izimbobo ku-PCB: enye iwukwenza ukuvuleka ngebhodi, okuvumela izinqubo ezilandelayo zenze ukuxhumana kukagesi phakathi kongqimba olungaphezulu, ungqimba olungezansi, kanye namasekhethi ongqimba angaphakathi ebhodi;enye iwukugcina ubuqotho besakhiwo kanye nokunemba kokuma kokufakwa kwengxenye ebhodini.
I-Vis eyimpumputhe kanye ne-vias engcwatshwe kabanzi kubuchwepheshe bokuxhumana okuphezulu kakhulu (HDI) kwe-HDI pcb, ikakhulukazi kumabhodi we-pcb wezendlalelo eziphakeme.I-Vis eyimpumputhe ngokuvamile ixhuma isendlalelo sokuqala kungqimba lwesibili.Kweminye imiklamo, i-vias eyimpumputhe nayo ingaxhuma isendlalelo sokuqala kungqimba lwesithathu.Ngokuhlanganisa ama-vias angaboni futhi angcwatshwe, ukuxhumana okwengeziwe kanye nokuminyana kwebhodi lesifunda okuphakeme okudingekayo ku-HDI kungafinyelelwa.Lokhu kuvumela ukwanda kokuminyana kwesendlalelo kumadivayisi amancane kuyilapho kuthuthukisa ukudluliswa kwamandla.I-Vis efihliwe isiza ukugcina amabhodi esekethe engasindi futhi ahlangene.Ukungaboni nokungcwatshwa ngemiklamo kuvame ukusetshenziswa ekudizayineni okuyinkimbinkimbi, ukukala isisindo, kanye nomkhiqizo we-elekthronikhi obiza kakhulu njengeama-smartphone, amaphilisi, kanyeimishini yezokwelapha.
Izimpumputhe ngeakhiwa ngokulawula ukujula kokumba noma ukukhipha nge-laser.Le yakamuva iyindlela evame kakhulu njengamanje.Ukupakishwa kwezimbobo kwakhiwa ngokwendlalelo ezilandelanayo.Okuphumayo ngezimbobo kungapakishwa noma kudidiyelwe, kwengeze izinyathelo ezengeziwe zokukhiqiza nokuhlola kanye nezindleko ezikhulayo.
Ngokusho kwenhloso kanye nomsebenzi wemigodi, zingahlukaniswa ngokuthi:
Ngezimbobo:
Ziyizimbobo ezenziwe ngensimbi ezisetshenziselwa ukuzuza ukuxhumana kukagesi phakathi kwezendlalelo ezihlukene ze-PCB, kodwa hhayi ngenjongo yokukhweza izingxenye.
PS: Ngezimbobo zingahlukaniswa futhi zibe imbobo ephumela, imbobo egqitshiwe, nembobo eyimpumputhe, kuye ngongqimba imbobo engena ngalo ku-PCB njengoba kushiwo ngenhla.
Izimbobo zengxenye:
Asetshenziselwa ukuhlanganisa nokulungisa izingxenye ze-electronic plug-in, kanye nezimbobo ezisetshenziselwa ukuxhumana kukagesi phakathi kwezingqimba ezihlukene zokuqhuba.Izimbobo zezingxenye ngokuvamile zenziwe ngensimbi, futhi zingasebenza njengendawo yokufinyelela yezixhumi.
Izimbobo ezifakwayo:
Ziyizimbobo ezinkulu ku-PCB ezisetshenziselwa ukuvikela i-PCB ku-casing noma esinye isakhiwo sokusekela.
Izimbobo zesikhala:
Akhiwa ngokuhlanganisa ngokuzenzakalelayo izimbobo eziningi ezingashadile noma ngokugaya izisele ohlelweni lokumba lomshini.Ngokuvamile asetshenziswa njengendawo yokukhweza yezikhonkwane zokuxhuma, njengezikhonkwane ezimise okweqanda zesokhethi.
Izimbobo zangemuva:
Kuyizimbobo ezijule kancane ezibhojwe ezimbotsheni ezicwebezekile ku-PCB ukuze kuhlukaniswe i-stub nokunciphisa ukubonakaliswa kwesignali phakathi nokudlulisa.
Okulandelayo ezinye izimbobo ezisizayo abakhiqizi be-PCB abangazisebenzisa ku-Inqubo yokukhiqiza ye-PCBukuthi onjiniyela bokuklama be-PCB kufanele bajwayele:
● Izimbobo zokuthola ziyizimbobo ezintathu noma ezine phezulu nangaphansi kwe-PCB.Ezinye izimbobo ebhodini ziqondaniswe nalezi zimbobo njengendawo yokubhekisela yokubeka izikhonkwane nokulungisa.Ezaziwa nangokuthi izimbobo eziqondiwe noma izimbobo zokuma okuqondiwe, zikhiqizwa ngomshini wembobo eqondiwe (umshini wokubhoboza we-optical punching noma umshini wokumba i-X-RAY, njll.) ngaphambi kokubhoboza, futhi zisetshenziselwa ukubeka nokulungisa izikhonkwane.
●Ukuqondanisa isendlalelo sangaphakathiizimbobo ezinye izimbobo onqenqemeni lwebhodi lezingqimba eziningi, ezisetshenziselwa ukubona ukuthi kukhona yini ukuchezuka ebhodini lezingqimba eziningi ngaphambi kokubhoboza ngaphakathi kwesithombe sebhodi.Lokhu kunquma ukuthi uhlelo lokumba ludinga ukulungiswa.
● Izimbobo zekhodi ziwumugqa wezimbobo ezincane ohlangothini olulodwa olungaphansi kwebhodi ezisetshenziselwa ukukhombisa ulwazi oluthile lokukhiqiza, njengemodeli yomkhiqizo, umshini wokucubungula, ikhodi yomqhubi, njll. Namuhla, izimboni eziningi zisebenzisa ukumaka nge-laser esikhundleni salokho.
● Izimbobo ze-Fiducial ezinye izimbobo ezinosayizi abahlukene onqenqemeni lwebhodi, ezisetshenziselwa ukukhomba ukuthi ububanzi bokubhoboza bulungile yini ngesikhathi sokumba.Namuhla, izimboni eziningi zisebenzisa obunye ubuchwepheshe ngale njongo.
● Amathebhu e-breakaway ayizimbobo zokunamathisela ezisetshenziselwa ukusika kwe-PCB nokuhlaziya ukubonisa ikhwalithi yezimbobo.
● Izimbobo zokuhlola ukungasebenzi kahle ziyizimbobo ezinamapulangwe ezisetshenziselwa ukuhlola ukuvinjelwa kwe-PCB.
● Izimbobo ezilindelekile ngokuvamile ziyizimbobo ezinganapuleti ezisetshenziselwa ukuvimbela ibhodi ukuthi limiswe emuva, futhi livame ukusetshenziswa ekumiseni phakathi nezinqubo zokubumba noma zokuthwebula izithombe.
● Izimbobo zamathuluzi ngokuvamile ziyizimbobo ezinganapuleti ezisetshenziselwa izinqubo ezihlobene.
● Izimbobo ze-rivet ziyizimbobo ezinganapuletiwe ezisetshenziselwa ukulungisa ama-rivets phakathi kwesendlalelo ngasinye se-core material kanye neshidi lokubopha ngesikhathi sokufakwa kwebhodi lezingqimba eziningi.Indawo ye-rivet idinga ukubhobozwa phakathi nokubhoboza ukuze kuvinjwe amabhamuza ukuthi angahlali kuleyo ndawo, okungabangela ukuphuka kwebhodi ezinqubweni zakamuva.
