HDI board , kulumikizana kwakukulu bolodi losindikizidwa
Ma board a HDI ndi amodzi mwamatekinoloje omwe akukula mwachangu mu ma PCB ndipo tsopano akupezeka ku ABIS Circuits Ltd.
Ma board a HDI amakhala ndi ma vias akhungu ndi/kapena okwiriridwa, ndipo nthawi zambiri amakhala ndi ma microvia a 0.006 kapena ocheperako.Amakhala ndi kachulukidwe kakang'ono kwambiri kuposa matabwa achikhalidwe.
Pali 6 mitundu yosiyanasiyana ya Zithunzi za HDI PCB , kuchokera pamwamba kupita kumtunda kudzera m'mabowo, ndi mabowo okwiriridwa ndi maenje, zigawo ziwiri kapena zingapo za HDI zomwe zimadutsa mabowo, magawo osasunthika opanda kugwirizana kwa magetsi, pogwiritsa ntchito awiriawiri wosanjikiza The alternating structure of the coreless structure and the coreless structure imagwiritsa ntchito awiriawiri wosanjikiza.
Gulu losindikizidwa lozungulira ndiukadaulo wa HDI Consumer Driven Technology In-pad kudzera munjira imathandizira matekinoloje ochulukirapo pamagawo ochepa, kutsimikizira kuti zazikulu sizikhala bwino nthawi zonse.Kuyambira chakumapeto kwa zaka za m'ma 1980, takhala tikuwona makatoni akugwiritsa ntchito makatiriji a inki, ofota kuti agwirizane ndi chikhatho cha dzanja lanu.Makompyuta am'manja ndikugwira ntchito kunyumba ali ndi ukadaulo wapamwamba kwambiri, womwe umapangitsa makompyuta kukhala ofulumira komanso opepuka, zomwe zimapangitsa ogula kugwira ntchito kutali kuchokera kulikonse. Ukadaulo wa HDI ndiye chifukwa chachikulu chakusinthaku.Chogulitsacho chimakhala ndi ntchito zambiri, kulemera kwapafupi ndi voliyumu yaying'ono.Zida zapadera, zida zazing'ono ndi zochepetsetsa zimapangitsa kuti zinthu zamagetsi zichepetse kukula pamene zikukulitsa luso, khalidwe ndi liwiro. Vias mu ndondomeko ya pad Kudzoza kochokera kuukadaulo wokwera pamwamba kumapeto kwa zaka za m'ma 1980 kwadutsa malire a BGA, COB, ndi CSP mpaka mainchesi ang'onoang'ono.The mu-pad kudzera ndondomeko amalola vias kuikidwa pamwamba pa lathyathyathya PAD.Mabowo odutsawo amakutidwa ndi kudzazidwa ndi epoxy yochititsa chidwi kapena yosagwirizana, kenako amaphimbidwa ndikukutidwa kuti asawonekere. Zikumveka zosavuta, koma zimatengera pafupifupi masitepe asanu ndi atatu kuti amalize ntchitoyi.Zida zamaluso ndi akatswiri ophunzitsidwa bwino amatchera khutu ku ndondomekoyi kuti akwaniritse zobisika zangwiro kudzera m'mabowo. Kudzera mtundu wodzaza Pali mitundu yambiri yosiyanasiyana ya zida zodzazira m'mabowo: non-conductive epoxy, conductive epoxy, copper-filled, silver-filled, and electrochemical plating.Izi zipangitsa kuti maenje okwiriridwa m'malo athyathyathya agulidwe kwathunthu kumalo abwinobwino.Kubowola, akhungu kapena kukwiriridwa vias, kudzaza, plating ndi kubisala pansi pa SMT pads.Kukonza mtundu uwu wa dzenje kumafuna zida zapadera ndipo kumatenga nthawi.Kangapo pobowola mkombero ndi ankalamulira mozama pobowola kumawonjezera processing nthawi. HDI yotsika mtengo Ngakhale kukula kwa zinthu zina za ogula kwatsika, khalidwe ndilofunika kwambiri la ogula pambuyo pa mtengo.Pogwiritsa ntchito ukadaulo wa HDI popanga, PCB ya 8-wosanjikiza-bowo imatha kuchepetsedwa kukhala phukusi laukadaulo la 4-wosanjikiza la HDI laling'ono la PCB.Kuthekera kwa mawaya a HDI 4-wosanjikiza bwino PCB kumatha kukwaniritsa ntchito zomwezo kapena zabwinoko monga PCB yokhazikika 8-wosanjikiza. Ngakhale njira ya microvia imawonjezera mtengo wa HDI PCB, kamangidwe koyenera ndi kuchepetsa chiwerengero cha zigawo zingathe kuchepetsa kwambiri mtengo wa mainchesi apakati pazinthu ndi chiwerengero cha zigawo. Pangani matabwa osagwirizana ndi HDI Kupanga bwino kwa HDI PCB kumafuna zida zapadera ndi njira, monga kubowola laser, plugging, kujambula kwachindunji kwa laser, ndi kuzungulira kopitilira muyeso.Mzere wa board wa HDI ndi wocheperako, malo ake ndi ang'onoang'ono, mphete ndi yothina, ndipo zida zapadera zocheperako zimagwiritsidwa ntchito.Kuti apange bwino gulu lamtunduwu, nthawi yowonjezera komanso ndalama zambiri pakupanga njira ndi zida zimafunikira. Laser pobowola luso Kubowola zing'onozing'ono zazing'ono kumapangitsa kuti njira zambiri zigwiritsidwe ntchito pamwamba pa bolodi la dera.Pogwiritsa ntchito mtengo wokhala ndi mainchesi 20 m'mimba mwake (1 mil), mtandawo umatha kuloŵa zitsulo ndi magalasi kupanga timabowo tating'onoting'ono.Zatsopano zatsopano zatulukira, monga laminates otsika-kutaya ndi yunifolomu galasi zipangizo ndi otsika dielectric constants.Zidazi zimakhala ndi kutentha kwakukulu kwa msonkhano wopanda kutsogolera ndipo zimalola kugwiritsa ntchito mabowo ang'onoang'ono. HDI board lamination ndi zipangizo Ukadaulo wapamwamba wa multilayer umalola opanga kuwonjezera mawiri awiri osanjikiza motsatizana kuti apange multilayer PCB.Kugwiritsa ntchito kubowola kwa laser kuti mupange mabowo mkati mwake kumathandizira kubisala, kujambula, ndikuyika musanayambe kukanikiza.Njira yowonjezera iyi imatchedwa sequential build.Kupanga kwa SBU kumagwiritsa ntchito ma vias olimba kuti athe kuwongolera bwino kutentha
