2 Ungqimba ENIG FR4 Heavy Copper PCB

Ngokukhula kogqinsi lwethusi, ukushuba kwe-PCB yethusi esindayo nakho kuyanda.I-PCB yethusi esindayo ngokuvamile ingaphezu kuka-2.0mm obukhulu, ukukhiqizwa kokumba ngenxa yobukhulu bobukhulu bepuleti kanye nezici zethusi eziwugqinsi, ukukhiqiza kunzima kakhulu.Mayelana nalokhu, ukusetshenziswa kwe-cutter entsha, ukunciphisa impilo yesevisi ye-drill cutter, ukumba kwesigaba sekube yisixazululo esisebenzayo sokumba i-PCB yethusi esindayo.Ngaphezu kwalokho, ukwenziwa kahle kwamapharamitha okubhoboza njengesivinini sokuphakelayo nesivinini sokuhlehlisa nakho kunethonya elikhulu kukhwalithi yembobo.

Inkinga yokugaya izimbobo eziqondiwe.Ngesikhathi sokumba, amandla e-X-Ray ayancipha kancane kancane ngokwanda kogqinsi lwethusi, futhi amandla awo okungena afinyelela umkhawulo ongaphezulu.Ngakho-ke, ku-PCB enogqinsi lwethusi obukhulu, akunakwenzeka ukuqinisekisa ukuchezuka kwepuleti lekhanda ngesikhathi sokumba.Mayelana nalokhu, umgomo wokuqinisekisa i-offset ungasethwa ezindaweni ezihlukene zonqenqema lwepuleti, futhi okuhlosiwe kokuqinisekisa i-offset kuqala kugaywe ngokuhambisana nendawo okuhlosiwe kudatha ephepheni lethusi ngesikhathi sokusika, kanye nethagethi. umgodi ocwecweni lwethusi kanye nembobo ehlosiwe yongqimba yangaphakathi ikhiqizwa ngokuhambisana ne-lamination.
