I-8 Layer ENIG Impumputhe Yangcwatshwa Nge-PCB
Mayelana neLeveli 1 HDI PCB
Ubuchwepheshe be-Level 1 HDI PCB busho imbobo eyimpumputhe ye-laser exhunywe kuphela kungqimba olungaphezulu kanye nobuchwepheshe bayo bokwakha imbobo yesendlalelo sesibili.
cindezela ngesikhathi esisodwa ngemva kokubhoboza → ngaphandle futhi cindezela ucwecwe lwethusi → bese kuba ukubhola ngelaser
Mayelana neLeveli 1 HDI PCB
Izinga 2 HDI PCB
Ubuchwepheshe be-Level 2 HDI PCB buwukuthuthukiswa kobuchwepheshe be-Level 1 HDI PCB.Ihlanganisa izinhlobo ezimbili ze-laser blind ngokubhoboza ngokuqondile kusuka kungqimba olungaphezulu kuya kwesesithathu, kanye ne-laser blind hole yokumba ngokuqondile kusuka kungqimba olungaphezulu kuya kwelesibili bese kusuka kungqimba lwesibili kuya kolwesithathu.Ubunzima bobuchwepheshe be-Level 2 HDI PCB bukhulu kakhulu kunobuchwepheshe be-Level 1 HDI PCB.
Cindezela kanye kanye ngemva kokubhoboza → ngaphandle futhi ucindezela ucwecwe lwethusi →i-laser, ukubhola→ngaphandle futhi ukucindezela icwecwe lethusi→ ukubhola nge-laser
8 izendlalelo Ze-Double Via Level 1 HDI PCB
Isibalo esingezansi siyizendlalelo ezingu - 8 zeleveli 2 ye-cross blind vias , le ndlela yokucubungula kanye nezendlalelo eziyisishiyagalombili ezingenhla zembobo yesitaki ye-oda lesibili , nazo zidinga ukudlala izimbobo zamalaser amabili .Kepha ama-perforations awapakishwanga ngaphezulu komunye okwenza kube nzima kakhulu ukusetshenzwa.
