Mayelana ne-Via-In-Pad PCB

Ama-PCB e-Via-In-Pad ngokuvamile ayizimbobo eziyizimpumputhe, ezisetshenziswa kakhulu ukuxhuma ungqimba lwangaphakathi noma ungqimba lwangaphandle lwesibili lwe-HDI PCB nongqimba lwangaphandle, ukuze kuthuthukiswe ukusebenza kukagesi nokuthembeka kwemikhiqizo kagesi, kufinyeze isignali. intambo yokudlulisela, yehlisa ukusabela kwe-inductive kanye nokusabela kwe-capacitive kolayini wokudlulisela, kanye nokuphazamiseka kwamagnetic kwangaphakathi nangaphandle.

Isetshenziselwa ukwenza.Inkinga enkulu yezimbobo zamapulaki embonini ye-PCB ukuvuza kwamafutha emigodini yamapulaki, okungase kuthiwe kuyisifo esiqhubekayo embonini.Kuthinta kakhulu izinga lokukhiqiza, isikhathi sokulethwa nokusebenza kahle kwe-PCB.Njengamanje, iningi lama-PCB aminyene aphezulu analolu hlobo lomklamo.Ngakho-ke, imboni ye-PCB idinga ukuxazulula ngokushesha inkinga yokuvuza kukawoyela ezimbotsheni zamapulaki

Izici Eziyinhloko Zokukhishwa Kwamafutha Kusuka Nge-Pad Plug Hole

Isikhala phakathi kwembobo yepulaki nephedi: enqubweni yangempela yokukhiqiza ye-PCB ephikisana nokushisela, ngaphandle kwembobo yepuleti kulula ukuphuma.Enye imbobo yepulaki nesikhala samafasitela singaphansi kuka-0.1mm 4mil) futhi imbobo yepulaki kanye nefasitela elivimbela ukudayiswa, ipuleti eliphambanayo libuye libe khona ngemva kokuphulukisa ukuvuza kukawoyela;

Ukujiya kwe-PCB nokuvuleka: ukujiya kwepuleti nokuvuleka kuhlotshaniswa kahle nezinga nengxenye yokuphuma kukawoyela;

Idizayini yefilimu ehambisanayo: lapho i-Via-In-Pad PCB noma imbobo encane yesikhala inqamula iphedi, ifilimu ehambisanayo ngokuvamile izoklama indawo yokukhanya endaweni yewindi (ukuveza uyinki embobeni) “ukugwema uyinki imbobo engenela kuphedi ngesikhathi sokuthuthukiswa, kodwa idizayini yokudlulisa ukukhanya incane kakhulu ukuze kuzuzwe umphumela wokuchayeka, futhi indawo yokudlulisa ukukhanya inkulu kakhulu ukuthi ingabangela kalula ukuvala.Ikhiqiza amafutha aluhlaza ku-PAD.

Izimo zokuphulukisa: ngenxa yokuthi idizayini yephoyinti elishintshashintshayo le-Via-In-Pad PCB kwifilimu kufanele ibe ncane kunembobo, ingxenye kayinki embobeni inkulu kunephuzu elikhanyayo uma liveziwe lingavezwa ukukhanya.Uyinki awulona ukwelapha okuzwela i-photosensitive, ukuthuthukiswa ngemva kwesidingo esijwayelekile sokuhlehlisa ukuchayeka noma i-UV kanye, ukuze kwelaphe uyinki lapha.Ungqimba lwefilimu elaphayo lwenziwa phezu komgodi ukuvimbela ukunwetshwa okushisayo kukayinki embobeni ngemva kokwelapha.Ngemva kokuphulukisa, isikhathi eside sesigaba sokushisa esiphansi, futhi sinciphisa izinga lokushisa kwesigaba sokushisa esiphansi, sincane isilinganiso kanye nezinga lokukhishwa kukawoyela;

Uyinki wokuxhuma: abakhiqizi abahlukene befomula kayinki umphumela wekhwalithi ehlukile nabo bazoba nomehluko othile.
