Ulwazi olubandayo: Yiziphi izinkathazo ngombala webhodi le-PCB?

Uyini umbala webhodi le-PCB, njengoba igama libonisa, lapho uthola ibhodi le-PCB, enembile kakhulu ukubona umbala wamafutha ebhodini, okungukuthi, ngokuvamile sibhekisela kumbala webhodi le-PCB, imibala evamile aluhlaza, aluhlaza okwesibhakabhaka, abomvu, amnyama nokunye.Abalandelayo uXiaobian babelana ngokuqonda kwabo imibala eyahlukene.

I-1, uyinki oluhlaza yiwona osetshenziswa kakhulu kunazo zonke, umcimbi omude kakhulu womlando, futhi emakethe yamanje futhi ushibhe kakhulu, ngakho oluhlaza kusetshenziswa inani elikhulu labakhiqizi njengombala oyinhloko wemikhiqizo yabo.

2, ngaphansi kwezimo ezijwayelekile, wonke umkhiqizo webhodi le-PCB enqubweni yokukhiqiza uzodlula ebhodini kanye nenqubo ye-SMT, ebhodini, kunezinqubo eziningi okufanele zidlule egumbini lokukhanya eliphuzi, ngoba umphumela wohlaza ophuzi igumbi elikhanyayo lingcono kuneminye imibala, kodwa lesi akusona isizathu esiyinhloko.Lapho izingxenye zokushisela ze-SMT, i-PCB ukuze idlule ekunamekelweni kwe-solder nokunamathisela kanye nenqubo yokugcina yesibani yokuhlola i-AOI, lezi zinqubo ziwukufunda ukulinganiswa kokuma kokubona, umbala wangemuva oluhlaza kumphumela wokuhlonza ithuluzi ungcono.

3.Common PCB imibala obomvu, ophuzi, oluhlaza okotshani, blue and black.Kodwa-ke, ngenxa yenqubo yokukhiqiza nezinye izinkinga, inqubo yokuhlola ikhwalithi yemigqa eminingi kusafanele ithembele kubasebenzi ukuze babone futhi bahlonze ngeso lenyama (Yebo, ukusetshenziswa okuningi kwamanje kobuchwepheshe bokuhlola inaliti endizayo).Endabeni yokukhanya okunamandla, amehlo alokhu egqolozele ebhodini, okuwumsebenzi omdala kakhulu ka-Liu, uma kuqhathaniswa, okuluhlaza kuyingozi kancane emehlweni, ngakho-ke abakhiqizi abaningi emakethe basebenzisa i-PCB eluhlaza.

I-4, isimiso sombala oluhlaza okwesibhakabhaka nomnyama ukuthi zixubene nezakhi zesibani se-cobalt ne-carbon, ne-conductivity ethile kagesi, esimweni samandla kungenzeka kube nezinkinga ze-short-circuit, futhi i-PCB eluhlaza ihambisana nemvelo, uma isetshenziswa izinga lokushisa eliphezulu, ngokuvamile ngeke likhiphe amagesi anobuthi.
Futhi kukhona nenani elincane labakhiqizi emakethe bazosebenzisa ibhodi le-PCB emnyama, izizathu eziyinhloko u-Xiaobian akholelwa ukuthi kunezizathu ezimbili: okokuqala, kubonakala kuphezulu, futhi ibhodi elimnyama akulula ukubona izintambo. , okuletha ubunzima obuthile ebhodini lokukopisha.Okufundile uXiaobian ukuthi amabhodi amaningi ashumekiwe e-Android manje aseyi-PCBS emnyama.

5, cishe kusukela phakathi nesikhathi sekwephuzile kwekhulu leminyaka elidlule, imboni isiqalile ukunaka umbala webhodi le-PCB, ikakhulukazi ngoba izinhlobo eziningi zebhodi ezisezingeni eliphezulu zabakhiqizi bomugqa wokuqala bamukele umklamo wombala webhodi le-PCB oluhlaza, ngakho-ke abantu kancane kancane bacabanga ukuthi PCB umbala oluhlaza kumele kube okusezingeni eliphezulu.

Okwedlule: Mayelana nemishini ye-DIP, abantu be-PCB abanye abawukhafuli umgodi osheshayo!

Olandelayo: Ingabe uyayiqonda imithetho emibili ye-PCB yokuklama laminated?
