Intangiriro
HDI ni impfunyapfunyo ya High-Density Interconnect.Nubuhanga bugoye bwo gushushanya PCB.Ikoranabuhanga rya HDI PCB rirashobora kugabanya imbaho zumuzingo zacapwe mumurima wa PCB.Ikoranabuhanga ritanga kandi imikorere myinshi nubucucike bwinshi bwinsinga nizunguruka.
Nukuvugako, imbaho zumuzunguruko za HDI zakozwe muburyo butandukanye nibisanzwe byacapwe byumuzunguruko.
HDI PCBs ikoreshwa na vias ntoya, imirongo n'umwanya.HDI PCBs ziremereye cyane, zifitanye isano rya hafi na miniaturizasi yabo.
Kurundi ruhande, HDI irangwa no gukwirakwiza inshuro nyinshi, kugenzura imirasire yumurengera, no kugenzura inzitizi kuri PCB.Bitewe na miniaturizasi yinama, ubucucike bwinama buri hejuru.
Microvias, impumyi kandi zishyinguwe, gukora cyane, ibikoresho bito n'imirongo myiza nibintu byose biranga imbaho zumuzingo za HDI zacapwe.
Ba injeniyeri bagomba gusobanukirwa neza nigishushanyo mbonera cya HDI PCB.Microchips kumurongo wacapwe wa HDI bisaba kwitabwaho cyane mugikorwa cyo guterana, hamwe nubuhanga buhebuje bwo kugurisha.
Mubishushanyo mbonera nka mudasobwa zigendanwa, terefone zigendanwa, HDI PCBs ni nto mubunini n'uburemere.Bitewe nubunini bwazo, PCI ya HDI nayo ntabwo ikunda gucika.
HDI Vias
Vias ni umwobo muri PCB ikoreshwa muguhuza amashanyarazi ibice bitandukanye muri PCB.Gukoresha ibice byinshi no kubihuza na vias bigabanya ubunini bwa PCB.Kubera ko intego nyamukuru yubuyobozi bwa HDI ari ukugabanya ubunini bwayo, vias nimwe mubintu byingenzi byingenzi.Hariho ubwoko butandukanye bwo kunyura.
Binyuze mu mwobo
Binyura muri PCB yose, kuva hejuru kurwego kugeza hasi, kandi byitwa kunyura.Kuri iyi ngingo, bahuza ibice byose byacapwe byumuzunguruko.Ariko, vias ifata umwanya munini kandi igabanya umwanya wibigize.
Impumyi binyuze
Impumyi zihuza gusa guhuza igice cyimbere nigice cyimbere cya PCB.Nta mpamvu yo gucukura PCB yose.
Yashyinguwe binyuze
Viyasi yashyinguwe ikoreshwa muguhuza ibice byimbere bya PCB.Via yashyinguwe ntabwo igaragara hanze ya PCB.
Micro binyuze
Micro vias ni ntoya ikoresheje ubunini buri munsi ya mil 6.Ugomba gukoresha laser ya dring kugirango ukore micro vias.Mubusanzwe rero, microvias zikoreshwa kubibaho bya HDI.Ibi biterwa nubunini bwayo.Kubera ko ukeneye ubucucike bwibigize kandi ntushobora guta umwanya muri HDI PCB, nibyiza gusimbuza izindi vias hamwe na microvias.Byongeye kandi, microvias ntabwo ihura nibibazo byo kwagura ubushyuhe (CTE) kubera ingunguru ngufi.
Ububiko
HDI PCB ikurikirana-ishyirahamwe-ry-ishyirahamwe.Umubare wibice cyangwa ibice birashobora kugenwa nkuko bisabwa.Ariko, ibi birashobora kuba ibice 8 kugeza kuri 40 cyangwa birenga.
Ariko umubare nyawo wibice biterwa nubucucike bwibisobanuro.Gutondekanya byinshi birashobora kugufasha kugabanya ingano ya PCB.Igabanya kandi ibiciro byo gukora.
By the way, kugirango umenye umubare wibice kuri HDI PCB, ugomba kumenya ingano yumurongo hamwe ninshundura kuri buri cyiciro.Nyuma yo kubamenya, urashobora kubara layer stackup isabwa kubuyobozi bwa HDI.
Inama zo gushushanya HDI PCB
1. Guhitamo ibice neza.Ikibaho cya HDI gisaba kubara pin nyinshi SMDs na BGAs ntoya ya 0,65mm.Ugomba kubahitamo neza nkuko bigira ingaruka kubwoko, ubugari bwumurongo hamwe na HDI PCB stack-up.
2. Ugomba gukoresha microvias kurubaho rwa HDI.Ibi bizagufasha kubona inshuro ebyiri umwanya wanyuze cyangwa undi.
3. Ibikoresho bifite akamaro kandi neza bigomba gukoreshwa.Nibyingenzi kubikorwa byibicuruzwa.
4. Kugirango ubone ubuso bwa PCB, ugomba kuzuza unyuze mu mwobo.
5. Gerageza guhitamo ibikoresho bifite igipimo kimwe cya CTE kubice byose.
6. Witondere cyane gucunga ubushyuhe.Menya neza ko utegura neza kandi ugategura ibice bishobora gukwirakwiza neza ubushyuhe burenze.
Ibyerekeye:
Iherereye muri Shenzhen, ANKE PCB ni umunyamwugaSerivise ya PCButanga afite uburambe bwimyaka irenga 10 mubikorwa bya elegitoroniki.Twakoze ibicapo byumuzunguruko byacapwe kandiserivisi yo guteranya ibihugu birenga 80 kwisi.Igipimo cyabakiriya bacu kiri hafi 99%, kandi twishimiye gutanga serivise nziza hafi.
Dufite umwihariko wo guha ibigo ibikoresho byuzuye kandi byujuje ubuziranenge PCB, guteranya PCB hamwe na serivisi zitanga isokoya prototype, ibicuruzwa bito / biciriritse / binini cyane bishingiye kuri metero kare 2000 hamwe nabakozi bafite ubuhanga barenga 400. Twiyemeje gutanga serivise yuzuye ya elegitoronike izafasha abashushanya PCB kuzana imishinga yabo kumasoko mugihe no kuri bije.
Ibiciro byacu birashobora guhinduka bitewe nibitangwa nibindi bintu byamasoko.Tuzohereza urutonde rwibiciro bishya nyuma yuko sosiyete yawe itwandikire kugirango umenye andi makuru.
Igiciro cyo kohereza giterwa nuburyo wahisemo kubona ibicuruzwa.Express mubisanzwe nuburyo bwihuse ariko kandi nuburyo buhenze cyane.Kurwanira mu nyanja nigisubizo cyiza kubwinshi.Igipimo cyibicuruzwa neza turashobora kuguha gusa niba tuzi amakuru arambuye, uburemere n'inzira.Nyamuneka twandikire kubindi bisobanuro.
Nibyo, burigihe dukoresha ibicuruzwa byiza byoherezwa hanze.Dukoresha kandi ibikoresho byihariye byo gupakira ibicuruzwa bishobora guteza akaga hamwe no kohereza ibicuruzwa bikonje byemewe kubintu byoroshye ubushyuhe.Impuguke zipfunyika hamwe nibisabwa gupakira birashobora kwishyurwa amafaranga yinyongera.
Kuburugero, igihe cyo kuyobora ni iminsi 7.Kubyara umusaruro mwinshi, igihe cyambere ni iminsi 20-30 nyuma yo kubona ubwishyu.Ibihe byambere bitangira gukurikizwa mugihe (1) twakiriye kubitsa, kandi (2) dufite ibyemezo byanyuma kubicuruzwa byawe.Niba ibihe byacu byo kuyobora bidakorana nigihe ntarengwa, nyamuneka jya hejuru y'ibyo usabwa kugurisha.Mubibazo byose tuzagerageza guhuza ibyo ukeneye.Mubihe byinshi turashobora kubikora.
Nibyo, turashobora gutanga ibyangombwa byinshi harimo Impamyabumenyi Yisesengura / Ibikorwa;Ubwishingizi;Inkomoko, nizindi nyandiko zohereza hanze aho bikenewe.
