Ubuyobozi bwa HDI , ubucucike buri hejuru icyapa cyumuzunguruko
Ikibaho cya HDI ni bumwe mu buhanga bwihuta cyane muri PCB kandi ubu buraboneka muri ABIS Circuits Ltd.
Ikibaho cya HDI kirimo impumyi na / cyangwa zashyinguwe, kandi mubisanzwe zirimo microviya ya 0.006 cyangwa diameter nto.Bafite ubwinshi bwumuzunguruko kuruta imbaho zumuzunguruko.
Hariho ubwoko 6 butandukanye bwa Ikibaho cya HDI PCB , kuva hejuru kugeza hejuru unyuze mu mwobo, hamwe nu mwobo washyinguwe kandi unyuze mu mwobo, ibice bibiri cyangwa byinshi bya HDI byanyuze mu mwobo, insimburangingo ya pasiporo idafite umurongo w’amashanyarazi, ukoresheje ibice byombi Imiterere ihinduranya yimiterere idafite ishingiro nuburyo budafite ishingiro ikoresha ibice byombi.
Icapa ryumuzingo ryacapishijwe hamwe na tekinoroji ya HDI Ikoranabuhanga ryabaguzi In-pad ikoresheje inzira ishyigikira tekinoroji nyinshi kurwego ruto, byerekana ko binini atari byiza buri gihe.Kuva mu mpera z'imyaka ya za 1980, twabonye kamera zikoresha amakarito yerekana ubunini bwa wino, yagabanutse kugirango ahuze ikiganza cyawe.Kubara mudasobwa igendanwa no gukorera murugo bifite ubundi buhanga buhanitse, bigatuma mudasobwa yihuta kandi yoroshye, bigatuma abakiriya bakora kure aho ariho hose. Ikoranabuhanga rya HDI nimpamvu nyamukuru yizo mpinduka.Igicuruzwa gifite imikorere myinshi, uburemere bworoshye nubunini buto.Ibikoresho bidasanzwe, micro-ibice nibikoresho byoroheje bituma ibicuruzwa bya elegitoronike bigabanuka mubunini mugihe wagura ikoranabuhanga, ubuziranenge n'umuvuduko. Vias muburyo bwa padi Guhumeka biturutse ku ikoranabuhanga rya mount mount mu mpera za 1980 ryasunitse imipaka ya BGA, COB, na CSP kuri santimetero nto.In-pad ikoresheje inzira ituma vias ishyirwa hejuru ya padi.Binyuze mu mwobo wasizwe kandi wuzuyemo epoxy itwara cyangwa idayobora, hanyuma igapfundikirwa kandi igashyirwaho kugirango itagaragara. Byumvikane byoroshye, ariko bisaba impuzandengo yintambwe umunani zinyongera kugirango urangize iyi nzira idasanzwe.Ibikoresho byumwuga hamwe nabatekinisiye batojwe neza bitondera cyane inzira kugirango bagere kubintu byihishe binyuze mu mwobo. Binyuze muburyo bwo kuzuza Hariho ubwoko bwinshi butandukanye bwibikoresho byuzuza umwobo: epoxy idayobora, epoxy itwara, yuzuye umuringa, yuzuye ifeza, hamwe namashanyarazi.Ibi bizatuma unyuze mu mwobo ushyinguwe mu butaka bugurishwa rwose ku butaka busanzwe.Gucukura, guhuma cyangwa gushyingura vias, kuzuza, gusasa no kwihisha munsi ya padi ya SMT.Gutunganya ubu bwoko bwu mwobo bisaba ibikoresho byihariye kandi bitwara igihe.Inzinguzingo nyinshi zo gucukura no kugenzura uburebure bwimbitse byongera igihe cyo gutunganya. Ikiguzi cyiza HDI Nubwo ingano y'ibicuruzwa bimwe byabaguzi yagabanutse, ubuziranenge buracyari ikintu cyingenzi cyabaguzi nyuma yigiciro.Ukoresheje tekinoroji ya HDI mugushushanya, ibice 8 byanyuze mu mwobo PCB irashobora kugabanuka kugeza kuri 4 ya tekinoroji ya tekinoroji ya PCI ya PCI PCB.Ubushobozi bwo gukoresha insinga za HDI zateguwe neza PC-4-PCB irashobora kugera kubikorwa bimwe cyangwa byiza nkibisanzwe 8-PCB. Nubwo inzira ya microvia yongerera igiciro cya HDI PCB, igishushanyo mbonera no kugabanya umubare wibice birashobora kugabanya cyane igiciro cya santimetero kare y'ibikoresho n'umubare w'ibyiciro. Kubaka imbaho zidasanzwe za HDI Gukora neza kwa HDI PCB bisaba ibikoresho nibikorwa bidasanzwe, nko gucukura lazeri, gucomeka, kwerekana amashusho ya laser, hamwe no gukomeza kumurika.Umurongo wibibaho bya HDI ni muto, intera ni nto, impeta irakomeye, kandi ibikoresho byihariye biroroshye.Kugirango ubashe kubyara neza ubu bwoko bwibibaho, birakenewe igihe cyinyongera nigishoro kinini mubikorwa byo gukora nibikoresho. Tekinoroji yo gucukura Gucukura micro-mwobo ntoya ituma tekinike nyinshi zikoreshwa hejuru yikibaho.Ukoresheje igiti gifite umurambararo wa microne 20 (mil 1), urumuri runini rushobora kwinjira mubyuma nikirahure kugirango bibe bito binyuze mumyobo.Ibicuruzwa bishya byagaragaye, nka laminates-igihombo gito hamwe nibikoresho byibirahure hamwe na dielectric nkeya.Ibi bikoresho bifite ubushyuhe bwinshi bwo guterana bidafite isasu kandi byemerera gukoresha ibyobo bito. Ikibaho cya HDI hamwe nibikoresho Ikoranabuhanga ryateye imbere ryemerera abashushanya kongeramo ibice bibiri byikurikiranya kugirango bakore PCB nyinshi.Gukoresha umwitozo wa laser kugirango ukore umwobo murwego rwimbere bituma isahani, ishusho, hamwe nibindi mbere yo gukanda.Iyi nzira yo kongeramo yitwa ubwubatsi bukurikiranye.SBU ikora ikoresha vias yuzuye kugirango yemere gucunga neza ubushyuhe
