Kev paub txog cov ntaub ntawv thermal interface
Raws li qhov loj ntawm cov nti txo qis, qib kev sib koom ua ke thiab lub zog ceev txuas ntxiv mus, ntau thiab ntau cov cua sov tau tsim thaum lub sijhawm ua haujlwm ntawm cov nti, uas ua rau qhov kub ntawm cov nti nce ntxiv, uas cuam tshuam rau kev ua haujlwm, kev ntseeg tau thiab lub neej ntawm cov khoom siv hluav taws xob zaum kawg. Cov ntaub ntawv thermal interface yog dav siv hauv tshav kub dissipation ntawm cov khoom siv hluav taws xob. Nws lub luag haujlwm tseem ceeb yog sau nruab nrab ntawm lub nti thiab lub dab dej kub thiab nruab nrab ntawm lub dab dej kub thiab lub dab dej kub kom tshem tawm cov huab cua hauv nws, kom cov cua sov uas tsim los ntawm cov nti tuaj yeem dhau los ntawm thermal interface sai dua.
Cov khoom raug xa mus rau sab nraud kom ua tiav lub luag haujlwm tseem ceeb ntawm kev txo qis kev ua haujlwm kub thiab ua kom lub neej ua haujlwm ntev. Kab lus no tshuaj xyuas cov xwm txheej kev lag luam thiab kev tshawb fawb tshiab ntawm cov khoom siv thermal interface. Cov xwm txheej hauv kev lag luam qhia txog cov khoom siv hluav taws xob thiab kev lag luam sib koom ntawm cov khoom siv thermal interface, qhov kev thov rau cov ntawv thov tseem ceeb ntawm cov khoom siv thermal interface, kev siv cov khoom siv thermal interface hauv kev sib txuas lus thiab lwm yam kev lag luam, thiab kev lag luam tsom xam cov khoom siv thermal interface. Cov kev tshawb fawb nce qib qhia txog kev tshawb fawb ntawm cov kws tshawb fawb hauv kev txhim kho cov thermal conductivity ntawm thermal interface cov ntaub ntawv nyob rau hauv xyoo tas los no, suav nrog kev tshawb fawb txog kev ua tiav ntawm cov khoom siv polymers thiab cov khoom siv thermally conductive polymers.
Thermal interface cov ntaub ntawv (TIMs) yog dav siv nyob rau hauv lub tshav kub dissipation ntawm hluav taws xob Cheebtsam. Lawv tuaj yeem ua tiav ntawm cov khoom siv hluav taws xob thiab lub dab dej kub kom tshem tawm cov huab cua nyob rau hauv, kom cov cua sov uas tsim los ntawm cov khoom siv hluav taws xob tuaj yeem hloov mus los ntawm cov khoom siv thermal interface sai dua rau lub tshuab hluav taws xob, nws ua tiav lub luag haujlwm tseem ceeb ntawm kev ua haujlwm qis. qhov kub thiab txias thiab ua kom lub neej ua haujlwm ntev.
Cov khoom siv hluav taws xob sib txuas feem ntau yog siv rau hauv cov khoom sib txuas ntawm cov khoom siv hluav taws xob sib txuas (chips) lossis microprocessors thiab cov dab dej kub lossis cov khoom siv hluav taws xob, nrog rau nruab nrab ntawm cov hluav taws kub thiab cov hluav taws kub (raws li qhia hauv daim duab 1). Raws li cov nti loj dhau los ua thinner, qib kev sib koom ua ke thiab lub zog ntom ntom txuas ntxiv, cov cua sov hauv cov nti nce siab, uas cuam tshuam rau cov nti' kev khiav hauj lwm ceev, kev ua haujlwm ruaj khov, thiab qhov kawg ntawm lub neej. Hauv 2016," Xwm" luam tawm ib tsab xov xwm hais tias" Vim yog 'kub tuag' tshwm sim los ntawm kev txuas ntxiv miniaturization ntawm cov khoom siv hluav taws xob, daim ntawv qhia thoob ntiaj teb semiconductor thev naus laus zis tsis tau tsom mus rau Moore Txoj Cai." Txij li thaum muaj ntau qhov sib txawv ntawm cov nti thiab lub dab dej kub thiab nruab nrab ntawm lub dab dej kub thiab lub dab dej kub, qhov sib txawv yog ntim nrog cua. Txawm li cas los xij, nws paub zoo tias huab cua yog qhov tsis zoo ntawm cov cua sov. Cov khoom siv thermal interface ua rau lub qhov khoob ntawm cov nti thiab lub dab dej kub thiab nruab nrab ntawm lub dab dej kub thiab lub dab dej kub, thiab tsim kom muaj cov hluav taws xob hluav taws xob ntawm cov nti thiab lub dab dej kub, thiab paub txog qhov hloov hluav taws xob sai ntawm cov nti.
Nyob rau hauv lub ntsej muag ntawm kev sib tw hnyav, kuv lub teb chaws kuj tau ua tib zoo saib xyuas nws ntawm lub teb chaws. Table 1 piav qhia txog cov cai muaj feem xyuam rau kev tshawb fawb thiab kev tsim kho thev naus laus zis ntawm cov ntaub ntawv thermal interface uas muab los ntawm kuv lub teb chaws. Ministry of Science thiab Technology ntawm Cov Neeg' lub koom pheej ntawm Tuam Tshoj tau xa tawm xyoo 2008 thiab tau pib ua 02 qhov tshwj xeeb tshwj xeeb (cov txheej txheem sib xyaw ua ke loj heev thiab cov cuab yeej siv) hauv 2009. Cov nyiaj IC tau pib hauv 2014 Tom qab ze li kaum xyoo ntawm kev txhawb nqa, kuv lub teb chaws' kev lag luam kev sib koom ua ke tau ua tiav ntau yam. Kev tsim kho, kev ntim khoom thiab kev lag luam kev soj ntsuam nyob rau hauv peb lub ntiaj teb. Txawm li cas los xij, cov khoom ntim khoom siv hluav taws xob high-end, uas yog cov khoom siv hauv paus, tseem cia siab rau kev xa khoom. Cov ntaub ntawv thermal interface tau dav siv hauv hluav taws xob thiab lwm yam kev lag luam, thiab lub xeev kuj tau tshaj tawm cov cai txhawb nqa los txhawb txoj kev loj hlob ntawm kev lag luam thermal interface khoom lag luam. Piv txwv li, hauv 2016, Ministry of Science thiab Technology tau tshaj tawm" Strategic Advanced Electronic Materials" tshwj xeeb qhov project thiab nteg tawm" High-power density electronic device thermal tswj cov ntaub ntawv thiab kev siv". Ib qho ntawm cov lus qhia kev tshawb fawb yog" Kev ua haujlwm siab thermal tswj rau high-power density thermal tswj." Interface cov ntaub ntawv".
Nrog rau kev nce ntxiv rau kev nyab xeeb cua sov dissipation nyob rau hauv cov khoom microelectronic, thermal interface cov ntaub ntawv kuj tseem niaj hnub tsim. Los ntawm thawj lub thermal roj, nws tau tsim rau ntau yam xws li thermal pads, thermal gels, thermal theem hloov cov ntaub ntawv, thermal adhesives, thermal tapes, thiab kua hlau. Tsoos polymer-raws li thermal interface cov ntaub ntawv suav txog ze li 90% ntawm tag nrho cov khoom, thaum cov ntaub ntawv ua kua hlau thermal interface account rau ib tug me me feem, tab sis lawv feem yog maj mam nthuav.
