Inqubo yokwelashwa kwe-Layer Pcb ebusweni: ukucwiliswa kwegolide ne-OSP

Lapho ukhetha inqubo yokwelapha engaphezulu (efana negolide lokucwiliswa, i-OSP, njll.) ye-PCB yakho enezingqimba ezi-3, kungaba umsebenzi onzima.Njengoba kunezinketho eziningi, kubalulekile ukukhetha inqubo yokwelashwa efaneleke kakhulu ukuze uhlangabezane nezidingo zakho ezithile.Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngokuthi ungakhetha kanjani ukwelashwa kwendawo engcono kakhulu ye-PCB yakho enezingqimba ezi-3, sigqamisa ubuchwepheshe be-Capel, inkampani eyaziwa ngokulawula izinga eliphezulu nezinqubo zokukhiqiza ze-PCB ezithuthukisiwe .

I-Capel idume ngama-PCB ayo aqinile, ama-PCB aguquguqukayo nama-HDI PCB.Ngezitifiketi ezinelungelo lobunikazi kanye nohlu olubanzi lwezinqubo zokukhiqiza ze-PCB ezithuthukile, u-Capel usezisungule njengomholi wemboni.Manje ake sibhekisise izici okufanele zicatshangelwe lapho ukhetha indawo engaphezulu ye-PCB enezingqimba ezi-3.

1. Isicelo nendawo

Okokuqala, kubalulekile ukucacisa isicelo nendawo ye-PCB enezingqimba ezi-3.Izinqubo ezihlukene zokwelashwa kwendawo zihlinzeka ngamazinga ahlukene okuvikela ekugqwaleni, i-oxidation nezinye izici zemvelo.Isibonelo, uma i-PCB yakho izovezwa ezimeni ezinzima, ezinjengomswakama ophezulu noma izinga lokushisa elidlulele, kuyanconywa ukuthi ukhethe inqubo yokwelapha engaphezulu enikeza ukuvikeleka okuthuthukisiwe, okufana negolide lokucwiliswa.

2. Izindleko nesikhathi sokulethwa

Esinye isici esibalulekile okufanele sicatshangelwe yizindleko nesikhathi sokuhola esihambisana nezinqubo ezahlukene zokwelashwa kwendawo.Izindleko zezinto ezibonakalayo, izidingo zabasebenzi kanye nesikhathi sokukhiqiza sisonke siyahlukahluka ngenqubo ngayinye.Lezi zici kufanele zihlolwe kuqhathaniswa nesabelomali sakho kanye nomugqa wesikhathi wephrojekthi ukuze wenze isinqumo unolwazi.Ubuchwepheshe be-Capel ezinqubweni zokukhiqiza ezithuthukisiwe buqinisekisa izixazululo ezingabizi futhi ezifika ngesikhathi ezidingweni zakho zokulungiselela indawo ye-PCB.

3. Ukuthobelana ne-RoHS

Ukuthobela i-RoHS (Umkhawulo Wezinto Eziyingozi) kuyisici esibalulekile, ikakhulukazi uma umkhiqizo wakho ungowemakethe yaseYurophu.Ezinye izindlela zokwelapha ezingaphezulu zingaqukatha izinto eziyingozi ezeqa imikhawulo ye-RoHS.Kubalulekile ukukhetha inqubo yokwelapha engaphezulu ehambisana nemithetho ye-RoHS.Ukuzibophezela kukaCapel ekulawuleni ikhwalithi kuqinisekisa ukuthi izinqubo zakhe zokwelapha ezingaphezulu ziyahambisana ne-RoHS, okukunikeza ukuthula kwengqondo uma kuziwa ekuthobeleni umthetho.

4. Solderability kanye Wire Bonding

I-solderability kanye nezici ze-wire bonding ze-PCB ziyizinto ezibalulekile zokucatshangelwa.Inqubo yokwelashwa kwendawo kufanele iqinisekise ukuthengiswa okuhle, okuholela ekunamatheleni kwe-solder okufanele ngesikhathi somhlangano.Ukwengeza, uma idizayini yakho ye-PCB ifaka isibopho sezintambo, inqubo yokwelapha engaphezulu kufanele ithuthukise ukwethembeka kwamabhondi ezintambo.I-OSP (i-Organic Solderability Preservative) iyinketho ethandwayo ngenxa yokuthengiswa kwayo okuhle kakhulu nokuhambisana kwe-wire bonding.

5. Iseluleko nokusekelwa kochwepheshe

Ukukhetha inqubo efanele yokwelashwa kwendawo ye-PCB enezingqimba ezi-3 kungaba nzima, ikakhulukazi uma umusha ekwenziweni kwe-PCB.Ukufuna iseluleko sochwepheshe nokusekelwa enkampanini ethembekile efana ne-Capel kungenza inqubo yokwenza izinqumo ibe lula.Ithimba lakwa-Capel elinolwazi lingakuqondisa enqubweni yokukhetha futhi lincome inqubo yokwelapha engaphezulu efaneleke kakhulu ngokusekelwe ezidingweni zakho ezithile.

Kafushane, ukukhetha ukwelashwa okungaphezulu okufanele kakhulu kwe-PCB yakho enezingqimba ezi-3 kubalulekile ekusebenzeni okuhle nokuphila isikhathi eside.Izinto ezifana nokusetshenziswa kanye nendawo ezungezile, izindleko nesikhathi sokuhola, ukuthobela i-RoHS, ukuthengiselana kanye nokubopha ngocingo kufanele kuhlolwe ngokucophelela.Ukulawulwa kwekhwalithi ye-Capel, izitifiketi ezinelungelo lobunikazi kanye nezinqubo zokukhiqiza ze-PCB ezithuthukisiwe ziyenza ikwazi ukuhlangabezana nezidingo zakho zokulungiselela indawo.Xhumana nochwepheshe bakwaCapel futhi uzuze olwazini lwabo olubanzi lwemboni kanye nolwazi lwabo.Khumbula ukuthi izinqubo zokwelashwa ezikhethwe ngokucophelela ezingaphezulu zingathinta kakhulu ukusebenza okuphelele nokuqina kwe-PCB enezingqimba ezi-3.
