Ngikholwa ukuthi abantu abaningi abayazi kahle imigomo ehlobene nemboni ye-elekthronikhi njengebhodi lesifunda le-PCB kanye nokucubungula kwe-chip ye-SMT. Lokhu kuvame ukuzwakala empilweni yansuku zonke, kodwa abantu abaningi abazi okuningi nge-PCBA futhi bavame ukudideka ne-PCB. Ngakho-ke yini i-PCBA? Uyini umehluko phakathi kwe-PCBA ne-PCB? Ake sazane.

I- PCBA:
Inqubo ye-PCBA: I-PCBA = umhlangano webhodi lesifunda ophrintiwe, okungukuthi, ibhodi le-PCB elingenalutho lidlula kuyo yonke inqubo ye-SMT yokulayisha kanye ne-plug-in ye-dip, ebizwa ngokuthi inqubo ye-PCBA kafushane.

II-PCB:
Ibhodi lesifunda eliphrintiwe (PCB) liyingxenye ebalulekile ye-elekthronikhi, ukusekelwa kwezingxenye ze-elekthronikhi kanye nomthwali wokuxhunywa kukagesi wezingxenye ze-elekthronikhi. Ngenxa yokuthi yenziwe ngokuphrinta nge-elekthronikhi, ibizwa ngokuthi ibhodi lesifunda “eliphrintiwe”.

Ibhodi Lesifunda Eliphrintiwe:
Isifinyezo sesiNgisi esithi PCB (ibhodi lesifunda eliphrintiwe) noma i-PWB (ibhodi locingo eliphrintiwe) livame ukusetshenziswa. Kuyingxenye ebalulekile ye-elekthronikhi, ukusekelwa kwezingxenye ze-elekthronikhi kanye nomhlinzeki wokuxhuma kwesifunda sezingxenye ze-elekthronikhi. Ibhodi lesifunda lendabuko lithatha indlela yokuphrinta i-etchant ukwenza isifunda nokudweba, ngakho-ke kubizwa ngokuthi ibhodi lesifunda eliphrintiwe noma ibhodi lesifunda eliphrintiwe. Ngenxa ye-miniaturization eqhubekayo kanye nokucwengwa kwemikhiqizo ye-elekthronikhi, okwamanje, amabhodi amaningi wesifunda enziwa ngokunamathisela i-etching resist (ukucindezela ifilimu noma ukunamathela) kanye nokushumeka ngemva kokuchayeka nokuthuthukiswa.
Ngasekupheleni kweminyaka yawo-1990, lapho kwenziwa izikimu eziningi zebhodi lesifunda eliphrintiwe elinezingqimba eziningi, ibhodi lesifunda eliphrintiwe elinezingqimba eziningi selisetshenziswe ngokusemthethweni kuze kube manje.

Umehluko phakathi kwe-PCBA ne-PCB:
1. I-PCB ayinazo izingxenye
2. I-PCBA isho ukuthi ngemva kokuba umenzi ethole i-PCB njengempahla eluhlaza, izakhi ze-elekthronikhi ezidingekayo ukuze zishise futhi zihlanganiswe ebhodini le-PCB nge-SMT noma i-plug-in processing, njenge-IC, resistor, capacitor, crystal oscillator, i-transformer nokunye. izingxenye ze-elekthronikhi. Ngemva kokushisa okuphezulu kokushisa esithandweni sokugeleza kabusha, ukuxhumana kwemishini phakathi kwezingxenye nebhodi le-PCB kuzokwakhiwa, ukuze kwakhiwe i-PCBA.
Kusukela kusingeniso esingenhla, singakwazi ukwazi ukuthi i-PCBA ngokuvamile ibhekisela kunqubo yokucubungula, engaqondwa futhi njengebhodi lesifunda eliqediwe, okungukuthi, i-PCBA ingabalwa kuphela ngemva kokuba izinqubo eziku-PCB seziqediwe. I-PCB isho okungenalutho ibhodi yesifunda ephrintiwe kungekho zingxenye kuwo.
