Njengoko izixhobo ze-elektroniki zinciphisa ubungakanani kwaye uyilo lwazo luba nzima ngakumbi, isidingo sincinci PCB kunye nezinto ezibekwe ngokuchanekileyo ziyanda. Oku kuqhuba ukufuna izixhobo kunye netekhnoloji enokuthi ikuphucule ukuchaneka kwamalungu amancinci, anzima. Kungenxa yoko le nto itekhnoloji yokuxinana okuphezulu (HDI) yandisa ubungakanani beli candelo lentengiso. Itekhnoloji ivumela ukwakhiwa kweepaneli ezixineneyo kakhulu ngenani elikhulu kakhulu lezinto nge-intshi nganye yesikwere enokufakwa ngokufanelekileyo. Eli nqaku livavanya ukukhula kunye nezibonelelo zokwenza i-HDI PCB.

Ukubaluleka kokusebenzisa imveliso ye-HDI PCB

Ngokwesiqhelo, iiPCBS zinendawo enye okanye ezimbini. Ii-PCBS ze-Multilayer zinokuba nandawo ukusuka kuma-3 ukuya kuma-20 maleko, kuxhomekeke kwisicelo kunye nobunzima bayo. Ii-PCI ze-HDI zinokuba nezingqimba ezingama-40 kwaye zinamacandelo afakwe ngokuchanekileyo, imigca ebhityileyo kunye nee-microholes kwisithuba esixineneyo. Ungabachonga ngemigca yabo ebhityileyo. Ukuveliswa kwe-HDI ye-PCB nako kuphumelele kwezinye iindawo. Nazi ezinye zazo:

Nge-HDI, unokuba neemvume ezininzi kunye nendibaniselwano yomaleko. Nangona ii-cores ziyinxalenye yoyilo loyilo lwe-PCB, kwaye zibonisiwe kumzobo, i-HDI inokufezekisa uyilo olungenasiseko. Unokuba ne-HDI ezimbini okanye nangaphezulu ngemingxunya yemingxunya, kunye nasemingxunyeni ngemingxunya engcwatyelweyo, kunye neendidi ezininzi zeebhodi ze-HDI. Landela inkqubo ye-pad-hole yokuhlangana okuphezulu kunye nenani elincinci lamanqanaba. Ukuba uthelekisa oku nobuchwephesha obuqhelekileyo bomngxunya, ungafikelela kumaqweqwe asi-8 ngoncedo lwamaleko ama-4 eHDI. Sebenzisa i-HDI, abaqulunqi banokulingana ngokulula kwizinto ezincinci ngokuqinileyo kwizithuba ezixineneyo. Ukongeza kwizinto ze-elektroniki zabathengi kunye neemoto, ii-HDI ze-PCBS ziluncedo ngakumbi kwizicelo ezibaluleke kakhulu kwimishini, ezinjengeenqwelo moya zokhuselo kunye nezixhobo zonyango.

Lo ngumzobo omele i-HDI yokubeka kwi-PCB enemilenze esibhozo: Izibonelelo zetekhnoloji ye-HDI, i-HDI ibonelela ngezibonelelo ezininzi kwi-PCB nakwimveliso iyonke. Nazi ezinye ezimbalwa: Ngaphandle kwamathandabuzo, itekhnoloji ye-HDI ibonelela ngokuchaneka okuphezulu. Ii-PCI ze-HDI zinesantya esingcono somqondiso kunye nelahleko yomqondiso esezantsi ngokuthelekiswa neetekhnoloji zangaphambili. Ngomatshini ophambili, unokumba imingxunya kwesona sincinci sincinci, ngelixa une-HDI, unokuvelisa ngokuchanekileyo ulwahlulo lwangaphakathi nolwangaphandle kwindawo yePCB. Nge-HDI, unokuba ne-cores encinci kwaye usebenze kakuhle kakhulu. Ungafezekisa ukunyamezelana kwemingxuma eqinileyo kunye nokulawulwa kobunzulu obulawulwayo. I-Microbore inokuba ncinane, enobubanzi obukhulu be-0.005. Ekuhambeni kwexesha, ukuveliswa kwe-HDI ye-PCB kungabizi kakhulu kuba kunciphisa inani lamanqanaba. Ngokubanzi, inyusa ukusebenza kombane kwezixhobo. Ukuba uhlanganisa ii-PCI ze-HDI zezicelo zeshishini, qiniseka ukunxibelelana nomenzi wePCB owaziwayo oya kuziqonda iimfuno zakho kwaye azenze ngokwezifiso ngokufanelekileyo.
