Kev Taw Qhia Kom Paub Txog Cov Txheej Txheem Ntau Lawm Thiab Daim Ntawv Thov Ntawm Cov Ntaub Ntawv Hluav Taws Xob
Koj puas paub? Ib qho zoo li daim ntaub fiberglass yog ib qho khoom siv tseem ceeb hauv AI servers, 5G hauv paus chaw nres tsheb, thiab siab -kawg PCBs. Los ntawm quartz xuab zeb mus rau lub davhlau ya nyob twg cov khoom siv hluav taws xob, cov ntaub siv hluav taws xob txuas cov tub ntxhais txuas ntawm cov khoom siv hluav taws xob hauv kev lag luam, thiab nws qhov kev ua tau zoo ncaj qha txiav txim siab cov teeb liab kis ceev thiab cov khoom siv kev ntseeg siab. Kab lus no piav qhia meej txog cov ntsiab lus tseem ceeb ntawm cov ntaub ntawv hluav taws xob, los ntawm tag nrho cov txheej txheem tsim khoom, kev ua haujlwm tseem ceeb, kev hloov kho tshiab mus rau qhov kawg - cov neeg siv daim ntawv thov.
I. Cov Txheej Txheem Ntau Lawm: Los ntawm Raw Khoom Quartz Sand rau Precision Substrate
Kev tsim cov ntaub ntawv hluav taws xob yog kev sib tw sib tw ntawm precision manufacturing:
1. Raw Material Preparation: High-purity quartz xuab zeb thiab pyrophyllite yog siv los ua cov khoom siv raw, yaj ntawm qhov kub siab tshaj 1600 degree, thiab kos los ntawm platinum spinneret rau hauv ultra-cov xov paj zoo nkauj hluav taws xob nrog ib txoj kab uas hla tsawg dua lossis sib npaug ntawm 9μm, suav txog 6% ntawm cov ntaub ntawv hluav taws xob.
2. Precision Weaving: Cov xov paj hluav taws xob yog warped thiab loj, ces woven rau hauv cov ntaub raw siv lub siab -paj weaving tshuab. High-end models can achieve a weft density of 1000 threads/inch, with a fabric flatness error<=2μm.
3. Cov ncej tseem ceeb-Kev ua tiav: Cov ntaub nyoos tau txais cov fiber ntau sib cais thiab kev kho tshuaj deg los txhim kho resin wetting, ua kom cov tooj liab tom qab-clad laminate yog npuas -dawb thiab tsis delaminate.
4. Kev soj ntsuam cov khoom tiav: Tsuas yog cov khoom uas dhau qhov kev sim nruj rau cov tuab, qhov hnyav, dielectric zog, thiab qhov tsis xws luag tuaj yeem mus rau hauv cov ntawv sau cia.
II. Core Performance: Cov cim tseem ceeb txiav txim siab PCB Kev Lag Luam
Electronic fabric yog ib qho tseem ceeb substrate rau tooj liab-clad laminates (CCLs). Ob yam tseem ceeb ntawm kev ua tau zoo txiav txim siab qhov khoom kawg tus nqi:
- Dielectric Properties (Dk/Df): Tsawg Dk ua rau cov teeb liab kis tau sai, thaum qis Df txo cov teeb liab poob. AI servers xav tau Dk Tsawg dua lossis sib npaug li 3.5 thiab Df Tsawg dua lossis sib npaug rau 0.0015, thaum cov khoom siv hluav taws xob zoo tib yam tsuas yog xav tau Dk ≈ 4.8.
- Mechanical thiab Thermal Stability: Muab cov qauv kev txhawb nqa rau PCB, tiv taus cov thermal shocks ntawm -50℃txog 260 degree, tiv thaiv warping thiab cracking, thiab ua kom cov cuab yeej siv tau ntev.
III. Generational Upgrades: Khoom Leaps hauv AI Era
Cov ntaub ntawv hluav taws xob tau ua tiav plaub tiam ntawm kev rov ua dua tshiab, thiab qhov sib txawv ntawm cov khoom siab -kawg yog irreversible:
- Generation 1 E- iav ntaub: Dk≈4.8, nqe 4-6 RMB/meter, siv hauv cov khoom siv hauv tsev thiab cov xov tooj qis kawg, suav txog 90% ntawm kev ua lag luam.
- Tiam 2 Tsawg-Dk ntaub: Dk≈4.2, nqe 30 RMB/meter, haum rau 5G hauv paus chaw nres tsheb thiab nruab nrab-rau- siab- kawg servers.
- Generation 3 Ultra-Low-Dk ntaub: Dk≈3.5, nqe 120 RMB/meter, siv hauv AI servers thiab siab - hloov ceev.
- Tiam 4 Quartz daim ntaub (Q ntaub): SiO₂ purity Ntau dua los yog sib npaug rau 99.95%, Dk≈2.2, tus nqi tshaj 500 RMB / meter, cov khoom siv kawg rau 1.6T optical modules thiab Chiplet ntim.
IV. Xaus-Cov Ntawv Thov Neeg Siv: Npog Tag Nrho Cov Hluav Taws Xob Hluav Taws Xob Kev Lag Luam
Electronic daim ntaub permeates tag nrho cov hluav taws xob scenarios los ntawm cov saw hluav taws xob → CCL → PCB → davhlau ya nyob twg:
- AI Computing Power: Siab-kawg AI server PCBs muaj 20-30 txheej, yuav tsum tau 18-24 meters ntawm Q-dawb ib chav tsev, nrog tus nqi 5-8 npaug ntawm cov servers ib txwm muaj.
- Kev sib txuas lus Infrastructure: 5G / 6G hauv paus chaw nres tsheb RF boards thiab siab -PCBs ceev hauv cov chaw khaws ntaub ntawv cia siab rau qis-tso hluav taws xob daim ntaub los xyuas kom meej cov teeb liab ruaj khov.
- Automotive Electronics: Lub zog tshiab tsheb ADAS thiab automotive radar PCBs yuav tsum tau ua kom muaj cua sov siab thiab tsis tshua muaj hluav taws xob nthuav dav.
- Advanced Ntim: IC substrates thiab chiplet ntim siv Tsawg-CTE daim ntaub los daws qhov teeb meem ntawm thermal expansion txuam.
7628 hluav taws xob daim ntaub, ib qho tseem ceeb substrate nyob rau hauv cov ntaub ntawv hluav taws xob kev lag luam, yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob cov ntaub ntawv uas ua rau kev lag luam hloov los ntawm kev loj hlob ntau mus rau qhov zoo, uas tau tsav los ntawm AI thiab siab - kev sib txuas lus ceev. Kev nkag siab txog kev tsim cov logic thiab kev ua tau zoo ciam teb ntawm cov ntaub ntawv hluav taws xob yog qhov tseem ceeb kom nkag siab txog cov hauv kev rau kev hloov pauv hauv tsev ntawm qib siab - cov ntaub ntawv kawg thiab kev txhim kho kev lag luam.
