Nhanganyaya
HDI chidimbu cheHigh-Density Interconnect.Iyo yakaoma PCB dhizaini tekinoroji.HDI PCB tekinoroji inogona kutapudza akadhindwa edunhu mabhodhi mumunda wePCB.Iyo tekinoroji inopawo kushanda kwepamusoro uye hukuru hukuru hwewaya uye maseketi.
Nenzira, HDI mabhodhi edunhu akagadzirwa zvakasiyana pane akajairwa akadhindwa edunhu mabhodhi.
HDI PCBs inofambiswa nediki vias, mitsetse uye nzvimbo.HDI PCBs dzakareruka zvakanyanya, izvo zvine hukama nekuita kwavo miniaturization.
Kune rimwe divi, HDI inoratidzirwa nepamusoro frequency kutapurirana, inodzorwa yakawandisa radiation, uye inodzorwa impedance paPCB.Nekuda kweiyo miniaturization yebhodhi, iyo bhodhi density yakakwira.
Microvias, mapofu uye akavigwa vias, kuita kwepamusoro, zvinhu zvitete uye mitsetse yakanaka zvese zviratidzo zveHDI zvakadhindwa matunhu ematunhu.
Mainjiniya anofanirwa kuve nekunzwisisa kwakakwana kwedhizaini uye HDI PCB yekugadzira maitiro.Microchips paHDI akadhindwa edunhu mabhodhi anoda kutariswa kwakakosha mukati megungano rekuita, pamwe nehunyanzvi hwekusodha.
Mune compact dhizaini senge laptops, nharembozha, HDI PCB idiki muhukuru uye huremu.Nekuda kwehukuru hwawo hudiki, HDI PCBs zvakare hainyanyi kutsemuka.
HDI Vias
Vias maburi muPCB anoshandiswa kubatanidza nemagetsi zvidimbu zvakasiyana muPCB.Kushandisa akawanda akaturikidzana uye kubatanidza navo vias kunoderedza PCB saizi.Sezvo chinangwa chikuru cheHDI bhodhi ndechekuderedza ukuru hwayo, vias ndeimwe yezvinhu zvayo zvakakosha.Kune mhando dzakasiyana dzemaburi.
Tkuburikidza neburi via
Iyo inoenda kuburikidza nePCB yese, kubva padenga repamusoro kusvika pazasi, uye inonzi via.Panguva ino, vanobatanidza zvikamu zvose zvebhodhi redunhu rakadhindwa.Nekudaro, vias zvinotora nzvimbo yakawanda uye kuderedza chikamu nzvimbo.
Bofuvia
Bofu vias anongobatanidza rekunze layer kune yemukati layer yePCB.Hapana chikonzero chekuboora PCB yese.
Kuvigwa via
Kuvigwa vias anoshandiswa kubatanidza yemukati akaturikidzana PCB.Akavigwa vias hazvionekwe kubva kunze kwePCB.
Microvia
Micro vias ndidzo diki kuburikidza nesaizi isingasviki 6 mils.Iwe unofanirwa kushandisa laser drilling kugadzira micro vias.Saka zvakanyanya, ma microvias anoshandiswa kune HDI mabhodhi.Izvi zvinokonzerwa nekukura kwayo.Sezvo uchida chikamu density uye haugone kutambisa nzvimbo muHDI PCB, zvine hungwaru kutsiva mamwe akajairika vias ne microvias.Pamusoro pezvo, mamicrovias haatambure nenyaya dzekuwedzera kwekushisa (CTE) nekuda kwemadhiramu mapfupi.
Stackup
HDI PCB stack-up isangano-ne-layer sangano.Huwandu hwematanho kana mastacks anogona kutariswa sezvinodiwa.Zvisinei, izvi zvinogona kuva zvikamu zvisere kusvika kune makumi mana kana kupfuura.
Asi huwandu chaihwo hwematanho hunoenderana nekuwanda kwematanho.Multilayer stacking inogona kukubatsira kuderedza PCB saizi.Inoderedzawo mari yekugadzira.
Nenzira, kuti uone huwandu hwezvikamu paHDI PCB, unofanirwa kuona saizi yekutevera uye mambure pane yega yega.Mushure mekuvazivisa, unogona kuverenga iyo stackup inodiwa kune yako HDI bhodhi.
Mazano ekugadzira HDI PCB
1. Kunyatsosarudzwa kwechikamu.HDI mabhodhi anoda yakakwira pini kuverenga SMDs uye BGAs idiki pane 0.65mm.Iwe unofanirwa kuzvisarudza zvine hungwaru sezvazvinokanganisa kuburikidza nemhando, tsvaga hupamhi uye HDI PCB stack-up.
2. Unofanira kushandisa microvias paHDI board.Izvi zvinokutendera iwe kuti uwane kaviri nzvimbo yevia kana imwe.
3. Zvishandiso zvinoshanda uye zvinobudirira zvinofanira kushandiswa.Izvo zvakakosha pakugadzirwa kwechigadzirwa.
4. Kuti uwane yakadzika PCB pamusoro, unofanira kuzadza kuburikidza nemakomba.
5. Edza kusarudza zvinhu zvine chiyero chakafanana cheCTE chezvikamu zvose.
6. Nyatsoteerera kutungamirirwa kwekushisa.Ita shuwa kuti wakanyatso gadzira uye kuronga maseru anogona kunyatso bvisa kupisa kwakanyanya.
