Iyini i-PCB yethusi esindayo?

Le PCB yakudala iyinketho yokuqala lapho imisinga ephezulu ingenakugwenywa: i- PCB yethusi ewugqinsi , ekhiqizwe ngobuchwepheshe bokufaka i-etching. Ama-PCB ethusi awugqinsi abonakala ngezakhiwo ezinogqinsi lwethusi ukusuka ku-105 ukuya ku-400 µm. Lawa ma-PCB asetshenziselwa imiphumela yamanje emikhulu (ephezulu) kanye nokwenza kahle kokuphatha okushisayo. I-copper ewugqinsi ivumela i-PCB-cross-sections enkulu yemithwalo yamanje ephezulu futhi ikhuthaza ukuchithwa kokushisa. Imiklamo evame kakhulu i-multilayer noma izinhlangothi ezimbili. 

Nakuba ingekho incazelo evamile ye-Heavy Copper, ngokuvamile kuyamukelwa ukuthi uma ama-ounces (oz) angu-3 (oz) ethusi noma ngaphezulu esetshenziswa ezendlalelo zangaphakathi nezangaphandle zebhodi lesifunda eliphrintiwe, libizwa ngokuthi i- PCB yethusi esindayo . Noma iyiphi isekethe enogqinsi lwethusi olungaphezu kuka-4 oz ngonyawo lwesikwele ngasinye (ft2) nayo ihlukaniswa njenge-PCB yethusi esindayo. Ithusi eledlulele lisho u-20 oz ku-ft2 ukuya ku-200 oz ngeft2 ngayinye.

I-PCB yethusi esindayo ikhonjwa njenge-PCB enogqinsi lwethusi olu-3 oz ku-ft2 ukuya ku-10 oz nge-ft2 ngayinye kuzindlalelo zangaphandle nezingaphakathi. I-PCB yethusi esindayo ikhiqizwa ngezisindo zethusi ezisukela ku-4 oz ku-ft2 ukuya ku-20 oz ku-ft2 ngayinye. Isisindo sethusi esithuthukisiwe, kanye nokucwenga okukhudlwana kanye ne-substrate efanelekile emigodini edlulayo kungashintsha ibhodi elibuthakathaka libe inkundla yezintambo ehlala isikhathi eside nethembekile. Amakhondaktha wethusi asindayo angakhuphula yonke i-PCB ukujiya kakhulu. Ukuqina kwethusi kufanele kucatshangelwe ngaso sonke isikhathi ngesikhathi sesiteji sokuklama isifunda. Umthamo wamanje wokuthwala unqunywa kusukela kububanzi nobukhulu bethusi esindayo.

Inzuzo eyinhloko yamabhodi esekethe yethusi esindayo amandla awo okusinda ekuchayekeni kaningi kumanje ngokweqile, amazinga okushisa aphakeme kanye nokuhamba ngebhayisikili okushisayo okuphindaphindayo, okungacekela phansi ibhodi lesifunda elivamile ngemizuzwana. Ibhodi yethusi esindayo inomthamo omkhulu wokubekezelela, okwenza ihambisane nezinhlelo zokusebenza ezimweni ezinzima ezifana nemikhiqizo yemboni yezokuvikela kanye ne-aerospace.

Ezinye zezinzuzo ezengeziwe zamabhodi esekethe yethusi esindayo yilezi:

Usayizi womkhiqizo ohlangene ngenxa yezisindo ezimbalwa zethusi kungqimba olufanayo lokujikeleza

Ama-avy-plated copper asindayo adlula amandla amanje aphezulu nge-PCB futhi asize ekudluliseleni ukushisa kusinki yokushisa yangaphandle.

Umehluko phakathi kwe-Standard PCB ne-Thick Copper PCB

Ama-PCB ajwayelekile angakhiqizwa ngezinqubo ze-copper etching kanye ne-plating. Lawa ma-PCB ahlanganiswe ukwengeza ukujiya kwethusi ezindizeni, imikhondo, ama-PTH, namaphedi. Inani lethusi elisetshenziswa ekukhiqizeni ama-PCB ajwayelekile ngu-1oz. Ekukhiqizeni i-PCB yethusi esindayo, inani lethusi elisetshenzisiwe likhulu kune-3oz.

Kumabhodi esekethe ajwayelekile, kusetshenziswa amasu e-copper etching kanye ne-plating. Kodwa-ke, ama-PCB ethusi esindayo akhiqizwa nge-etching ehlukile kanye ne-step plattting. Ama-PCB ajwayelekile enza imisebenzi elula kuyilapho amabhodi ethusi esindayo enza imisebenzi esindayo.

Ama-PCB ajwayelekile aqhuba ukusebenza kwamanje okuphansi kuyilapho ama-PCB ethusi esindayo enza umthamo wamanje ophezulu. Ama-PCB ethusi aminyene alungele izinhlelo zokusebenza ezisezingeni eliphezulu ngenxa yokusabalalisa kwawo okushisayo okusebenzayo. Ama-PCB ekhopha esindayo anamandla okusebenza angcono kunama-PCB ajwayelekile. Amabhodi esekethe ethusi esindayo athuthukisa amandla ebhodi asetshenziswa kulo.

Ezinye izici ezenza ama-PCB ethusi awugqinsi ahluke kwamanye ama-PCB

Isisindo sethusi: Lesi isici esiyinhloko esihlukanisayo sama-PCB ethusi esindayo. Isisindo sethusi sibhekisela esisindweni sethusi esisetshenziswa endaweni yonyawo lwesikwele. Lesi sisindo ngokuvamile silinganiswa ngama-ounces. Kubonisa ukujiya kwethusi kungqimba.

Izendlalelo zangaphandle: Lezi zibhekisela ezingqimbeni zethusi zangaphandle zebhodi. Izingxenye ze-elekthronikhi zivame ukuboshelwa ezingqimbeni zangaphandle. Izendlalelo zangaphandle ziqala nge-foil yethusi embozwe ngethusi. Lokhu kusiza ukwandisa ukushuba. Isisindo sethusi sezendlalelo zangaphandle sisethwe kusengaphambili imiklamo evamile. Umkhiqizi we-PCB yethusi esindayo angashintsha isisindo nokujiya kwekhopha ukuze kuhambisane nesidingo sakho.

Izendlalelo zangaphakathi: Ugqinsi lwe-dielectric, kanye nenqwaba yethusi yezendlalelo zangaphakathi, kuchazwe kusengaphambili kumaphrojekthi ajwayelekile. Kodwa-ke, isisindo sethusi nokushuba kulezi zendlalelo kungalungiswa ngokusekelwe ezidingweni zakho.

Ama-PCB ethusi elisindayo asetshenziselwa izinjongo eziningi ezifana nama-planar transformer, ukuchithwa kokushisa, ukusatshalaliswa kwamandla aphezulu, iziguquli zamandla, njll. Kunesidingo esikhulayo samabhodi agqoke ithusi esindayo kumakhompuyutha, ezimoto, ezempi, nezilawuli zezimboni.

Amabhodi esekethe aphrintiwe ethusi elisindayo nawo asetshenziswa ku:

Izimpahla zamandla, iziguquli zamandla

Ukusabalalisa amandla
