Cov neeg tsim khoom tuaj yeem txhim kho qhov ua tau zoo thiab kev pabcuam lub neej ntawm coj los ntawm kev tswj xyuas cov cua sov kom zoo.Ua tib zoo xaiv cov khoom siv cua sov thiab cov txheej txheem kev thov yog qhov tseem ceeb heev.

Peb yuav tsum xav txog qhov tseem ceeb hauv kev xaiv cov khoom lag luam - kev siv cov khoom siv hluav taws xob tswj cov khoom siv hluav taws xob.Tsis muaj teeb meem ntawm cov ntim khoom lossis cov khoom siv sib txuas, txhua qhov sib txawv hauv qhov nruab nrab ntawm cov cua sov yuav ua rau txo qis ntawm cov cua sov dissipation.

Rau thermal conductive ntim resin, tus yuam sij rau kev vam meej yog los xyuas kom meej tias cov resin tuaj yeem ntws nyob ib ncig ntawm lub tsev, suav nrog nkag mus rau qhov sib txawv me me.Cov dej ntws zoo li no yuav pab tshem tawm qhov tsis sib xws ntawm huab cua thiab ua kom tsis muaj cua sov tawm thoob plaws hauv chav tsev.Txhawm rau ua tiav daim ntawv thov no, cov resin xav tau qhov tseeb thermal conductivity thiab viscosity.Feem ntau, raws li thermal conductivity ntawm resin nce, lub viscosity kuj nce.

Rau cov ntaub ntawv sib txuas, cov viscosity ntawm cov khoom lossis qhov tsawg kawg nkaus thickness thaum lub sij hawm thov muaj kev cuam tshuam zoo rau cov thermal kuj.Yog li ntawd, piv nrog cov khoom uas tsis tshua muaj thermal conductivity thiab tsis tshua muaj viscosity, cov tebchaw nrog cov thermal conductivity thiab siab viscosity tsis tuaj yeem diffuse tusyees mus rau saum npoo, tab sis muaj cov cua kub ntau dua thiab qis dua cov cua sov.Txhawm rau kom ua kom cov cua sov ua kom zoo tshaj plaws, cov neeg siv yuav tsum tau daws cov teeb meem ntawm cov thermal conductivity, tiv thaiv kev tiv thaiv, daim ntawv thov thickness thiab txheej txheem.

Nrog rau kev loj hlob sai ntawm kev lag luam hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv lubkev siv ntawm LED, cov khoom siv thev naus laus zis yuav tsum ua kom tau raws li qhov xav tau ntau dua thiab siab dua cov cua kub dissipation.Cov cuab yeej no tam sim no kuj tau pauv mus rau ntim cov khoom sib txuas kom muab cov khoom ntim ntau dua rau cov khoom, yog li txhim kho thermal conductivity thiab liquidity.
