Nrog kev nce qib ntawm thev naus laus zis tsis tu ncua, cov khoom siv hluav taws xob tau ua lub luag haujlwm tseem ceeb hauv peb lub neej txhua hnub. Txawm li cas los xij, cov khoom siv hluav taws xob ua tau zoo no - ua kom muaj cua sov ntau thaum lub sijhawm ua haujlwm, thiab kev ua kom cov cua sov no tau dhau los ua qhov teeb meem nyuaj. Hlau substrates tau tshwm sim los ua cov khoom tseem ceeb los daws qhov teeb meem no.
Ib lub hlau substrate yog ib lub rooj tsav xwm Circuit Court nrog lub hauv paus hlau. Nws lub luag haujlwm tseem ceeb yog muab cov thermal conductivity zoo, yog li pab cov khoom siv hluav taws xob dissipate cua sov sai. Piv nrog rau cov tsoos FR-4 substrates, hlau substrates muaj ntau dua thermal conductivity thiab txhim kho txhua yam muaj zog, txhim kho kev ntseeg tau thiab kev pab lub neej ntawm cov khoom siv hluav taws xob.
Hom hlau substrates muaj xws li txhuas, tooj liab, thiab hlau. Aluminium substrates yog dav siv nyob rau hauv LED teeb pom kev zoo, fais fab modules, thiab lwm yam teb vim lawv lub teeb yuag, tsis muaj nqi, thiab zoo heev thermal conductivity. Copper substrates, nrog rau lawv cov thermal conductivity siab heev thiab cov khoom hluav taws xob zoo heev, ua lub luag haujlwm hloov tsis tau hauv siab - lub zog hluav taws xob.
Cov txiaj ntsig ntawm kev siv hlau substrates txuas ntxiv tshaj qhov kub dissipation. Vim lawv lub zog txhua yam zoo heev, cov hlau substrates tuaj yeem tiv taus qhov kev ntxhov siab ntawm lub cev, ua rau lawv zoo tagnrho rau ib puag ncig uas muaj kev vibration lossis poob siab. Hlau substrates kuj tuaj yeem txhim kho nrog kev kho saum npoo zoo li anodizing los txhim kho lawv cov kev tiv thaiv corrosion thiab zoo nkauj.
Thaum hlau substrates muaj ntau qhov zoo, cov ntawv thov tshwj xeeb yuav tsum tau txiav txim siab thaum xaiv ib qho. Piv txwv li, aluminium substrates tej zaum yuav yog ib qho kev xaiv tsim nyog rau qhov hnyav - cov ntawv thov rhiab heev, thaum tooj liab substrates yuav tsim nyog rau cov ntawv thov uas xav tau thermal conductivity siab heev.
Nyob rau hauv luv luv, hlau substrates, raws li ib tug npaum tshav kub dissipation tov, ua lub luag hauj lwm tseem ceeb nyob rau hauv niaj hnub electronics manufacturing. Kev xaiv tsim nyog thiab siv cov ntaub ntawv no tuaj yeem txhim kho kev ua tau zoo thiab kev ua neej nyob ntawm cov khoom siv hluav taws xob, ua tau raws li qhov xav tau ntawm kev siv thev naus laus zis ntau ntxiv.
