Thaum tham txog lub hauv paus tseem ceeb ntawm cov ntawv laminates tooj liab (CCLs), cov ntaub fiberglass hluav taws xob feem ntau hu ua "ntaub fiberglass." Tsis ntev los no, ntau tus thawj coj yuav khoom thiab cov engineers tau nug: Puas yog T-iav, Q-iav, thiab cov ntaub qis-Dk suav tias yog cov ntaub iav hluav taws xob siab? Dab tsi yog cov ntaub hluav taws xob qis kawg hauv kev ua lag luam, thiab qhov sib txawv tseem ceeb nyob qhov twg?

Niaj hnub no, peb rhuav tshem cov tswv yim no kom meej meej los pab koj nkag siab txog kev ua lag luam, cov kev ua tau zoo, thiab cov xwm txheej ntawm kev siv ntau yam ntaub fiberglass hluav taws xob, ua haujlwm ua cov ntaub ntawv siv tau rau kev xaiv cov khoom siv thiab kev soj ntsuam cov khoom siv.

Cov Lus Qhia Sai:Cov ntaub T-iav, Q-iav, thiab cov ntaub qis-Dk yog cov ntaub iav hluav taws xob tshwj xeeb uas ua haujlwm tau zoo, tab sis lawv cov lus qhia txog kev siv tshuab txawv kiag li. Cov ntaub iav E-iav txheem tseem yog cov ntaub hluav taws xob qis-rau-nruab nrab feem ntau hauv kev lag luam.

I. Cov Ntaub Siv Hluav Taws Xob Zoo Tshaj Plaws Ua Dab Tsi?

Cov ntaub iav hluav taws xob ua haujlwm ua "pob txha hlau txhawb nqa" sab hauv cov laminates uas muaj tooj liab. Thaum impregnated nrog resin, nws txiav txim siab lub zog kho tshuab, thermal stability, thiab kev ua haujlwm xa xov ntawm PCB substrates. Cov kev txhim kho thiab cov teeb meem daws tau los ntawm peb cov ntaub high-end loj sib txawv heev.

1. T-iav (Npuag Qis-CTE)

• Kev Tshwj Xeeb Tseem Ceeb:Kev nthuav dav thermal tsawg thiab kev ua haujlwm tiv thaiv kev sib tsoo.
• Lub Tshuab:T-iav tsis tsom mus rau qhov poob dielectric qis heev. Hloov chaw, nws cov ntsuas tseem ceeb yog qhov coefficient qis heev ntawm thermal expansion (CTE). Thaum lub sijhawm ntim khoom, qhov kub thiab txias hloov pauv hnyav heev. Yog tias lub substrate nthuav dav thiab cog lus tsis sib xws hauv qab cua sov, nws yooj yim ua rau lub substrate warpage thiab solder joint failure. T-iav yog tsim tshwj xeeb los daws qhov teeb meem "thermal mismatch" no.

• Kev Lag Luam Toj roob hauv pes:Cov tuam txhab txawv teb chaws xws li Nitto Boseki (Nittobo) tswj hwm, nrog rau cov chaw tsim khoom hauv tsev kom ua kom cov qauv qhia thiab kev lees paub me me.

2. Npuag Low-Dk (Npuag Dielectric Tsis Tu Ncua / Npuag Iav Ceev Tiam 2)

• Kev Tshwj Xeeb Tseem Ceeb:Txo qhov poob ntawm kev xa xov tooj cua rau kev sib txuas lus ceev ceev.
• Lub Tshuab:Cov iav E-txheej txheem qhia txog kev poob dielectric siab heev. Thaum lub teeb liab ceev nce ntxiv, qhov kev txo qis ntawm lub teeb liab yuav hnyav heev thiab suab nrov nrov zuj zus. Cov ntaub Low-Dk ua kom zoo dua cov qauv iav kom txo qis dielectric constant (D_k) thiab dissipation factor (D_f) cov nqi, ua kom ntseeg tau tias cov teeb liab ceev ceev muaj kev ncaj ncees.
• Cov Ntawv Thov Tseem Ceeb:5G chaw nres tsheb, 800G optical transceiver modules, cov motherboards AI server ib txwm muaj, cov keyboards ceev ceev, thiab cov ntaub ntawv tseem ceeb rau M7/M8 qib CCLs.
• Tus Nqi Tseem Ceeb:Cov pawg fiberglass loj tshaj plaws tam sim no siv rau hauv 224Gbps thiab qis dua cov PCBs ceev ceev thiab cov khoom siv computer.
• Kev Lag Luam Toj roob hauv pes:Kev lag luam hauv tebchaws tab tom nce qib sai sai, nrog rau kev tsim khoom loj twb tau pib lawm, txawm hais tias qhov sib txawv ntawm kev muab khoom thiab kev thov tseem muaj.

3. Q-Iav (Quartz Npuag/ Tiam 3 Ultra-High-Speed ​​Electronic Fabric)

• Kev Tshwj Xeeb Tseem Ceeb:Qhov kawg qis qis, ua haujlwm ua cov khoom siv kho vajtse computer tiam tom ntej.
• Lub Tshuab:Cov khoom siv raw rau Q-iav tsis yog iav ib txwm muaj lawm, tab sis yog cov fiber ntau quartz uas muaj purity siab. Nws qhov kev ua tau zoo ua tiav qhov kev dhia ceev ceev, thawb D_k thiab D_f mus rau qhov siab tshaj plaws ntawm cov ntaub ntawv fiberglass uas twb muaj lawm.
• Cov Ntawv Thov Tseem Ceeb:1.6T cov hloov pauv network, CPO (Co-Packaged Optics), cov neeg rau zaub mov AI tiam tom ntej siv Rubin architecture, thiab cov laug cam circuit boards uas muaj zaus siab heev, ceev ceev.
• Xwm Txheej Tam Sim No:Feem ntau nyob rau theem kev lees paub thiab theem kev nce qib me me, uas muaj peev xwm tsim khoom tsawg thiab cov nqi siab.
• Kev Lag Luam Toj roob hauv pes:Muaj cov teeb meem thev naus laus zis siab tshaj plaws, nrog cov thawj coj txawv teb chaws tuav qhov zoo dua ua ntej thaum cov neeg tsim khoom hauv tsev tseem tab tom tawg los ntawm cov teeb meem tseem ceeb.

Cov Lus Qhia Txog Peb Lub Luag Haujlwm Siab Tshaj Plaws:

• T-Iav:Tiv thaiv kev hloov pauv; tseem ceeb rau cov khoom ntim khoom.
• Cov Ntaub Low-Dk:Txo qhov poob ntawm lub teeb liab; tam sim no yog lub hauv paus tseem ceeb rau AI servers.
• Q-Iav:Kev ua tau zoo tshaj plaws; khaws cov khoom siv rau cov khoom siv ceev ceev ultra-high-speed tiam tom ntej.

II. Dab tsi yog Low-End Electronic Fabric? (Tus qauv E-Iav)

Cov ntaub siv hluav taws xob qis uas peb feem ntau hais txog feem ntau yog hais txog tus qauvE-iav ntaub, muaj cov qauv zoo li 7628, 2116, thiab 1080. Nws sawv cev rau pawg ntaub iav hluav taws xob uas muaj zog tshaj plaws thiab muaj ntau tshaj plaws hauv kev lag luam CCL.

Cov Yam Ntxwv Tseem Ceeb:

1. Kev Tsim Qauv Laus & Cov Txheej Txheem Yooj Yim:Tsim tawm ntau los ntawm ntau lub Hoobkas thoob ntiaj teb nrog lub peev xwm tsim khoom ntau.
2. Cov Txheej Txheem Txheem:D_k, D_f, thiab cov khoom siv thermal nthuav dav yog cov khoom ib txwm tsis muaj kev ua kom zoo dua tshwj xeeb.
3. Tus nqi qis & Kev siv tau ntau yam:Muaj kev siv nyiaj tsim nyog rau cov ntawv thov dav dav.

Cov Xwm Txheej ntawm Daim Ntawv Thov Hauv Qab:

Cov laug cam hluav taws xob rau cov khoom siv hauv tsev, cov khoom siv hluav taws xob dav dav, cov laug cam fais fab, cov PCBs tswj kev lag luam, thiab cov laug cam ntau txheej qis--qhov tseeb yog cov xwm txheej thoob ntiaj teb uas tsis xav tau kev sib kis ceev heev lossis kev ruaj khov thermal.

Lus Cim: Qhov sib txawv ntawm tus nqi ntawm cov ntaub zoo thiab cov ntaub pheej yig tuaj yeem ncav cuag kaum npaug. Qhov sib txawv no tsis yog los ntawm qhov sib txawv ntawm kev ua haujlwm, tab sis los ntawm qhov sib txawv kiag li ntawm cov qauv iav, cov khoom siv raw huv, thiab tag nrho cov txheej txheem tsim khoom.

III. Tej Yam Uas Yuav Tsum Tsis Txhob Ua Thaum Yuav Khoom Thiab Xaiv Khoom

1. Tsis txhob xav tias "Cov ntaub zoo tuaj yeem ua tau txhua yam xwm txheej":Txawm hais tias T-iav muaj kev ruaj khov zoo heev, nws qhov kev ua haujlwm dielectric yog qhov nruab nrab; siv nws rau cov motherboard server ceev ceev tsis tsim nyog. Ntawm qhov tod tes, cov ntaub low-Dk xa cov teeb liab zoo heev, tab sis nws cov CTE tsis ua raws li cov qauv ntim khoom siab heev. Lawv tsis tuaj yeem hloov ib leeg yam tsis muaj kev txwv.
2. Qib Siab Tsis Txhais Tau Tias Qhov Muag Tsis Pom Kev:Cov ntaub Low-Dk tau ua tiav kev loj hlob hauv tsev; txawm li cas los xij, ntau qhov project T-glass thiab Q-glass tseem tab tom ua raws li kev lees paub nruj. Kev hloov cov neeg muag khoom yuav tsum tau kuaj xyuas kev ntseeg tau zoo.
3. Cov projects tsis tas yuav siv Q-Glass yam tsis muaj kev xav vim lawv yog cov khoom siv siab heev:Rau GB200 thiab cov khoom siv 800G uas twb muaj lawm, cov ntaub uas hloov kho qis-Dk tuaj yeem ua tau raws li qhov xav tau ntawm theem no. Q-iav yog ib feem ntawm txoj kev txhim kho tiam tom ntej; qhia nws nruj me ntsis raws li qhov xav tau kom tsis txhob tsim ntau dhau uas ua rau cov nqi khoom siv nce siab.
