Iningi labathengi befekthri ye-elekthronikhi badidekile mayelana nentengo yama-PCB.ngisho nabanye abantu abanolwazi lweminyaka eminingi ekuthengeni kwe-PCB bangase bangasiqondi ngokugcwele isizathu sangempela.Eqinisweni, intengo ye-PCB yakhiwe izici ezilandelayo:
Okokuqala, amanani ahlukile ngenxa yezinto ezahlukene ezisetshenziswa ku-PCB.
Ukuthatha izendlalelo eziphindwe kabili ze-pcb njengesibonelo, i-laminate iyahlukahluka kusuka ku-FR-4, CEM-3, njll. ngobubanzi obusuka ku-0.2mm kuya ku-3.6mm.Ugqinsi lwethusi luyahlukahluka kusuka ku-0.5Oz kuya ku-6Oz, konke okubangele umehluko omkhulu wamanani.Izintengo ze-inki ze-soldermask nazo zihlukile kuzinto ezijwayelekile zikayinki we-thermosetting kanye nempahla ye-inki eluhlaza eyi-photosensitive.
Okwesibili, amanani ahlukile ngenxa yezinqubo ezahlukene zokukhiqiza.
Izinqubo ezahlukene zokukhiqiza ziholela ezindlekweni ezahlukene.Okufana nebhodi eligqize ngegolide kanye nebhodi elifakwe ngothayela, ukuma kwendlela yokuqondisa nokushaya, ukusetshenziswa kwemigqa yesikrini sikasilika kanye nemigqa yefilimu eyomile kuzokwakha izindleko ezihlukene, okuholela ekuhlukeni kwamanani.
Okwesithathu, amanani ahlukile ngenxa yobunkimbinkimbi nokuminyana.
I-PCB izoba yizindleko ezihlukile ngisho noma izinto zokwakha nenqubo kuyafana, kodwa ngobunkimbinkimbi obuhlukene kanye nokuminyana.Isibonelo, uma kunezimbobo eziyi-1000 kuwo womabili amabhodi esekethe, ububanzi bembobo yebhodi elilodwa bukhulu kuno-0.6mm futhi ububanzi bembobo kwelinye ibhodi bungaphansi kuka-0.6mm, okuzokwenza izindleko zokumba ezihlukene.Uma amabhodi esifunda amabili afana kwezinye izicelo, kodwa ububanzi bomugqa buhlukile bubuye bubangele izindleko ezihlukene, njengokuthi ububanzi bebhodi elilodwa bukhulu kuno-0.2mm, kanti elinye elinalo lingaphansi kuka-0.2mm.Ngoba ububanzi bamabhodi bungaphansi kuka-0.2mm anezinga eliphezulu elinesici, okusho ukuthi izindleko zokukhiqiza zingaphezu kokuvamile.
Okwesine, amanani ahlukile ngenxa yezidingo ezihlukahlukene zamakhasimende.
Izidingo zekhasimende zizothinta ngqo izinga elingenasici ekukhiqizeni.Njengezivumelwano zebhodi elilodwa le-IPC-A-600E class1 zidinga izinga lokuphasa elingu-98%, kuyilapho izivumelwano zesigaba3 zidinga kuphela izinga lokuphasa elingu-90%, okubangela izindleko ezihlukene zefekthri futhi ekugcineni kuholele ezinguqukweni zentengo yomkhiqizo.
