Vim li cas cov ntaub ntawv hluav taws xob tuaj yeem ua lub luag haujlwm rau siab -kawg Circuit Court boards?
Nyob rau hauv ib lub sijhawm ntawm kev nce qib AI, 5G, thiab siab -kawg suav lub zog, lub rooj tsav xwm hluav taws xob muaj peev xwm nqa tau siab -ceev teeb liab los ntawm cov chips thiab ruaj khov rau qhov kub thiab txias yog "lub siab" ntawm txhua yam khoom siv hluav taws xob. Tus yuam sij rau kev txhawb nqa lub siab no thiab txiav txim siab nws qhov kev ua tau zoo qab nthab feem ntau yog zais hauv - zoo li hluav taws xob zoo tib yam - qib fiberglass daim ntaub (electronic fabric). Nws tsis yog yooj yim xwbfiberglass ntaub; nws yog "steel skeleton" thiab "sib nqus txoj kev loj" ntawm siab -kawg PCBs. Niaj hnub no, peb yuav piav qhia nyob rau hauv ib qho mus vim li cas cov ntaub ntawv hluav taws xob tau dhau los ua cov txheej txheem tseem ceeb uas tsis tuaj yeem hloov tau rau siab -kawg Circuit Court boards, tsom rau nws cov kev ua tau zoo, kev lag luam tsim nyog, thiab kev cuam tshuam thev naus laus zis.
I. Kev Ua Tau Zoo Hluav Taws Xob: Tus "Stable Steward" rau High-Frequency, High-Speed Signals
Cov ntsiab lus tseem ceeb rau siab -kawg Circuit Court boards (tshwj xeeb yog cov siv hauv AI servers, 5G lub hauv paus chaw nres tsheb, thiab siab - hloov pauv ceev) yog: ceev teeb liab kis tau tus mob thiab tsawg attenuation. Electronic daim ntaub zoo kawg nkaus ua tau raws li cov cai no.
- Tsawg Dielectric Constant, Tsawg Poob: Cov ntaub fiberglass ib txwm qeeb siab siab -cov cim ceev thiab ua kom sov, thaum siab -kawg hluav taws xob daim ntaub, los ntawm siab- cov qauv purity thiab precision weaving, txo qhov dielectric qhov tsis tu ncua (Dk) kom qis dua 3.5 thiab dielectric poob (2.0.DF) Cov ntaub ntawv qhia tau hais tias 10% txo qis hauv dielectric tas li tuaj yeem ua ob lub teeb liab ceev; qis dielectric poob ua rau txo qis kev sib kis, kom ntseeg tau tias tsis muaj kev cuam tshuam ultra- siab- cov cim ceev ntawm 112Gbps rau 1.6Tbps.
- Superior Rwb thaiv tsev: Cov ntaub ntawv hluav taws xob nws tus kheej tsis yog -conductive thiab muaj hluav taws xob tsis zoo, tiv thaiv kev luv luv thiab crosstalk nyob rau hauv siab -cov kab hluav taws xob ntau, ua kom muaj kev nyab xeeb hluav taws xob nyob rau hauv txoj kab hluav taws xob nyuaj.
II. Qauv thiab Thermal Stability: "Core Skeleton" ntawm Circuit Board
High-kawg PCBs yuav tsum tau tiv taus siab - kub soldering, ntev - lub sij hawm siab - load cua sov, thiab thermal cycling shocks; Tsis txhob deforming, tawg, los yog warping yog qhov tseem ceeb.
- Ultra-High Mechanical Strength: Precision-woven los ntawm ultra- cov xov hluav taws xob zoo nrog ib txoj kab uas hla tsawg dua lossis sib npaug li 9 micrometers, nws yog nyias tsis tau muaj zog heev, muab kev txhawb nqa nruj rau PCB thiab tswj qhov raug qhov tseeb thoob plaws hauv cov txheej txheem etching, lamination, thiab deg.
- Ultra-High Temperature Resistance thiab Low Thermal Expansion (Low-CTE): Nrog rau qhov muag muag tshaj 700 degree, nws tuaj yeem tiv taus qhov kub siab ntawm reflow soldering. High-kawg Tsawg-CTE cov ntaub ntawv hluav taws xob muaj cov thermal expansion coefficient tsawg dua los yog sib npaug li 3ppm/degree, nthuav tawm cov thermal compatibility nrog tooj liab thiab chips. Nws tsis warp lossis tsim kua muag ntawm qhov kub thiab txias, tiv thaiv kev sib koom ua ke qaug zog tsis ua haujlwm.
- Chemically ruaj khov thiab corrosion{1}}resistant: Resistant mus rau acids thiab alkalis, av sov, thiab kev laus, ua kom ntseeg tau thiab ruaj khov kev lag luam ntawm kev lag luam -qib, automotive- qib, thiab tub rog- qib PCBs rau kwv yees li 15 xyoo.
III. Hloov tau rau cov txheej txheem Advanced: Tus "Ideal Carrier" rau siab -Kev sib xyaw ua ke
Tam sim no, PCBs tab tom hloov zuj zus mus rau ultra-nyias, ntau- txheej, siab- ntom, thiab micro- ntawm cov qauv tsim, thiab cov ntaub ntawv hluav taws xob zoo haum rau cov txheej txheem siab heev.
- Ultra- nyias, sib xws, thiab tiaj tiaj: Siab- cov ntaub ntawv hluav taws xob kawg (xws li 106 thiab 1080 ultra- cov lus qhia tshwj xeeb) yog nyias li kaum ntawm micrometers, nrog cov fibers zoo sib xws thiab tsis muaj qhov tsis xws luag. Lawv tsim nyog rau 10-30 txheej siab- txheej PCBs thiab HDI high-density PCB lamination, kom ntseeg tau qhov tuab tuab ntawm txhua txheej thiab muaj zog interlayer sib txuas.
- Cov resin wettability zoo heev: Tom qab kev kho deg, nws zoo kawg nkaus ua ke nrog epoxy resin thiab cov resins tshwj xeeb los ua siab -lub zog, ruaj khov heev tooj liab-clad laminate (CCL), ib qho tseem ceeb ntawm PCB substrates.
IV. Kev lag luam xav tau: Cov khoom siv zoo rau AI thiab siab -Speed Era
Nrog rau kev loj hlob ntawm AI servers, kev ntim khoom chiplet siab heev, thiab 800G / 1.6T optical modules, cov khoom siv ib txwm tsis txaus. High-cov ntaub ntawv hluav taws xob kawg tau dhau los ua cov khoom siv hauv lub cev rau kev suav cov txheej txheem.
- AI Server Boards: Tus nqi ntawm Q- daim ntaub siv rau ib chav tsev yog 5 npaug ntawm cov servers ib txwm siv, xav tau Dk/Df tsawg heev thiab CTE tsawg heev.
- Advanced Ntim (CoWoS/FC-BGA): Tsawg-CTE daim ntaub hluav taws xob yuav tsum tau siv los daws cov teeb meem ntawm chip stacking warpage thiab thermal stress.
- 5G/6G thiab Millimeter Wave: Tsuas yog tsawg- dielectric cov ntaub ntawv hluav taws xob tuaj yeem tiv taus siab - zaus teeb liab poob thiab xyuas kom muaj kev sib txuas lus ruaj khov.
Cov ntaub ntawv hluav taws xob tsis yog lub luag haujlwm txhawb nqa, tab sis lub hauv paus kev ua tau zoo, cov qauv txheej txheem, thiab cov teeb liab lav ntawm siab - kawg Circuit Court boards. Nrog nws qhov tshwj xeeb hluav taws xob, thermal, thiab cov khoom siv kho tshuab, nws txhawb nqa lub hauv paus kho vajtse rau AI, 5G, thiab siab -kawg suav. Yog tsis muaj siab -kawg hluav taws xob ntaub, yuav tsis muaj siab -PCBs kev ua tau zoo thiab cov cuab yeej siv computer siab heev.
Nyob rau hauv lub neej yav tom ntej, raws li cov ntaub ntawv iterate rau qis Dk, qis CTE, thiab siab purity, cov ntaub ntawv hluav taws xob yuav nyob twj ywm tseem ceeb tshaj plaws thiab irreplaceable tseem ceeb substrate rau siab - kawg PCBs.
