Zipangizo zamagetsi zikayamba kucheperachepera ndipo kapangidwe kake kamakhala kovuta, kufunika kocheperako PCB ndizomwe zimayikidwa bwino kwambiri zikuchulukirachulukira. Izi zikuyendetsa kufunikira kwa zida ndi ukadaulo zomwe zitha kukonza kulondola kwa magawo ang’onoang’ono, ovuta motero. Ichi ndichifukwa chake ukadaulo wa high density interconnect (HDI) umakulitsa gawo la msikawu. Tekinolojeyi imalola kuti pakhale mapanema wandiweyani okhala ndi zida zochulukirapo zochulukirapo zomwe zimatha kukhazikitsidwa bwino. Nkhaniyi ikufotokoza kukula ndi maubwino opanga HDI PCB.

Kufunika kogwiritsa ntchito kupanga ma HDI PCB

Nthawi zambiri, PCBS imakhala ndi gawo limodzi kapena awiri. Multilayer PCBS imatha kukhala ndi magawo atatu mpaka 3, kutengera ntchito ndi zovuta zake. HDI PCBS imatha kukhala ndi zigawo 40 ndipo imakhala ndi magawo oyenera, mizere yopyapyala ndi ma microholes m’malo ophatikizika. Mutha kuwazindikira ndi mizere yawo yopyapyala. Kupanga kwa HDI PCB kwakwaniritsanso kupambana m’malo ena. Nawa ena mwa iwo:

Ndi HDI, mutha kukhala ndi zilolezo zingapo komanso kuphatikiza kosanjikiza. Ngakhale ma cores ndi gawo la kapangidwe ka PCB, ndipo akuwonetsedwa pachithunzichi, HDI imatha kukwaniritsa kapangidwe kopanda maziko. Mutha kukhala ndi ma HDI awiri kapena kupitilira apo kudzera m’mabowo, komanso kudzera m’mabowo kudzera m’mabowo, ndi mitundu ingapo yama board a HDI. Tsatirani njira yopyola poboola kuti musonkhane pazitali ndi zigawo zochepa. Ngati mungafanizire izi ndi njira yanthawi zonse, mutha kufikira magawo 8 mothandizidwa ndi zigawo 4 za HDI. Pogwiritsa ntchito HDI, opanga amatha kulumikiza zigawo zing’onozing’ono zolimba kwambiri m’malo ophatikizika. Kuphatikiza pa zamagetsi zamagetsi zamagalimoto ndi magalimoto, HDI PCBS imathandizanso makamaka pantchito zofunikira kwambiri, monga ndege zodzitchinjiriza ndi zida zamankhwala.

Ichi ndi chithunzi choyimira cha HDI chokhazikitsidwa pa PCB yosanjikiza eyiti: Ubwino waukadaulo wa HDI, HDI imapereka maubwino ambiri ku PCB komanso malonda ake onse. Nawa ochepa: Mosakayikira, ukadaulo wa HDI umapereka kulondola kwambiri. HDI PCBS ili ndi mayendedwe abwinoko komanso otayika ochepa poyerekeza ndi ukadaulo wakale. Ndi makina otsogola, mutha kuboola mabowo kukula kwake kocheperako, pomwe muli ndi HDI, mutha kutulutsa molondola magawo amkati ndi akunja mumalo ophatikizika kwambiri a PCB. Ndi HDI, mutha kukhala ndimakina ochepa kwambiri komanso kuboola kwabwino kwambiri. Mutha kukwaniritsa zolekerera zolimba komanso kuboola mozama. Microbore ikhoza kukhala yaying’ono, yokwanira kutalika kwa 0.005. M’kupita kwanthawi, kupanga HDI PCB kumakhala kosafuna ndalama chifukwa kumachepetsa kuchuluka kwa zigawo. Ponseponse, imathandizira magwiridwe antchito amagetsi. Ngati mukusonkhanitsa HDI PCBS pazogwiritsa ntchito mafakitale, onetsetsani kuti mwakumana ndi wopanga PCB wodziwika yemwe angamvetse zomwe mukufuna ndikuzisintha moyenera.
