18 layer HDI yefoni ine yakakosha marara akakora

Nhanganyaya

HDI chidimbu cheiyo yakakwirira-dentity interconnect. Iyo inzvimbo yakaoma pcb dhizaini. HDI PCB tekinoroji inogona kuderera yakadhindwa matunhu ematunhu muPCB munda. Iyo tekinoroji inopawo kukosha kwekuita uye yakakura density yemahwisi nematunhu.

Nenzira, mapuranga ematunhu HDI akagadzirwa zvakasiyana-siyana pane zvakajairika dunhu redunhu wedunhu.

HDI PCBS inopihwa nediki vias, mitsara uye nzvimbo. HDI PCBs akanyanya kuremerwa, ayo anonyatsoenderana neangu miniaturization.

Kune rimwe divi, HDI inoonekwa neyakakwira frequency kutapurirana, inodzorwa radiation radiation, uye yakadzora kurwiswa paPCB. Nekuda kweiyo miniaturization yebhodhi, iyo bhodhi density yakakwira.

Microvias, mapofu uye akaviga Vias, kushanda kwakanyanya, zvinhu zvakajeka uye mitsara yakanaka uye mitsara yakanaka marefu ese eHDI yakadhindwa matunhu ematunhu eHDI akapetwa.

Mainjiniya anofanirwa kuve nekunzwisisa kwakakwana kweiyo dhizaini uye HDI PCB yekugadzira maitiro. Microchips paHDI yakadhindwa matunhu emabhodhi anoda kutarisisa kwakakosha mumugungano egungano, pamwe nehunyanzvi hwakanaka hwekutengesa.

Mumabendedhi ezvigadzirwa kunge malaptops, mafoni, HDI PCBs mashoma muhukuru uye uremu. Nekuda kwehukuru hwavo hukuru, HDI PCBS hazvina zvakare kushomeka kupaza.

HDI Vias 

VISI ISHE MISANGANO muPCB iyo inoshandiswa kune magetsi emagetsi zvikamu zvakasiyana muPCB. Kushandisa akawanda marita uye kuvabatanidza neVias kunodzora PCB size. Sezvo chinangwa chikuru chechikepe cheHdi ndechekuderedza saizi yayo, vias chimwe chezvakanyanya kukosha zvinhu. Kune dzakasiyana mhando dzemabhiza.

THombe holea kuburikidza

Iyo inoenda kuburikidza neiyo PCB yese, kubva pane pamusoro peganda rezasi kusvika pasi, uye inonzi via. Panguva ino, ivo vanobatanidza zvese zvevatemo vedunhu rakadhindwa wedunhu. Nekudaro, vias utore nzvimbo yakawanda uye kuderedza chikamu chikamu.

Bofuvia

Bofu ViaLing ingobatanidza iya yekunze kune iyo yemukati yePCB. Hapana chikonzero chekuchera PCB yese.

Kuvigwa kuburikidza

Kuvigwa Vias inoshandiswa kubatanidza iyo yemukati yezvikamu zvePCB. Kuvigwa vias hakuonekwe kubva kunze kwePCB.

Microvia

Micro Vias vizi diki kuburikidza saizi isingasviki 6 mils. Iwe unofanirwa kushandisa laser inodhiraira kuumba microir vias. Saka chaizvo, Micrevas inoshandiswa kumabhodhi eHDI. Izvi zvinodaro nekuda kwehukuru hwayo. Sezvo iwe uchida chikwangwani density uye usingakwanise kutambisa nzvimbo muHDI PCB, kuchenjera kutsiva zvimwe zvinhu zvakajairika neMicrovias. Pamusoro pezvo, Micrevas haatamburi kubva kune inopararira yekuwedzera nyaya (cte) nekuda kwemarongo avo mapfupi.

Stackup

HDI PCB Stack-kumusoro iSangano Rinoyera-Rayer. Nhamba yezvikamu kana madhiri inogona kutsanangurwa sezvinodiwa. Nekudaro, izvi zvinogona kuve zvisere zvisere kusvika makumi mana ematanho kana anopfuura.

Asi iyo chaiyo nhamba yematemo zvinoenderana nehuremu hwechiedza. Multilayer Stacking inogona kukubatsira kuderedza PCB size. Izvo zvakare zvinoderedza mari yekugadzira.

Nenzira, kuti uone huwandu hwezviyero pane hdi PCB, iwe unofanirwa kuona saizi yekutevera uye mambure pane rimwe nerimwe dura. Mushure mekuvazivisa, unogona kuverenga iyo layer stackup inodiwa kune yako HDI Board.

Matipi ekugadzira HDI PCB

1. Precise component sarudzo. HDI Board anoda yakakwira PIN kuverenga uye bgas idiki pane 0.65mm. Iwe unofanirwa kuvasarudza zvine hungwaru sezvavanokanganisa kuburikidza nemhando, trace upamhi uye HDI PCB stack-up.

2. Iwe unofanirwa kushandisa Micrevias pane Hdi Board. Izvi zvichakubvumidza iwe kuti uwane kaviri iyo nzvimbo yeaina kana imwe.

3. Zvishandiso zviri zviviri zvinobudirira uye zvinoshanda zvinofanirwa kushandiswa. Izvo zvakakosha pakugadzira kuumbwa kwechigadzirwa.

4. Kuti utore flat PCB pamusoro, iwe unofanirwa kuzadza iyo makomba.

5. Edza kusarudza zvinhu zvine chiyero chimwe chete checte kune ese matanda.

6 Ita shuwa iwe iwe dhizaini uye kuronga zviyero zvinogona kunyatsoisa kupisa kwakanyanya.
