Siv cov qauv tsim kom muaj kev sib haum xeeb kom ua tiav cov cua kub dissipation Vim qhov tsis zoo thermal conductivity ntawm cov resin nyob rau hauv lub rooj tsavxwm thiab qhov tseeb hais tias tooj liab foil kab thiab qhov yog zoo conductors ntawm tshav kub, ua rau cov seem ntawm tooj liab ntawv ci thiab nce tus naj npawb ntawm thermally conductive. qhov yog lub ntsiab txhais ntawm dissipating tshav kub. Txhawm rau ntsuas qhov thermal muaj peev xwm ntawm PCB, nws yog ib qho tsim nyog los xam qhov sib npaug thermal conductivity (cua eq) ntawm cov khoom sib xyaw uas muaj ntau yam ntaub ntawv nrog cov thermal conductivity sib txawv ib los ntawm ib qho rau insulating substrates rau PCBs.

Cov khoom siv ntawm tib lub rooj tsavxwm luam tawm yuav tsum tau npaj kom deb li deb tau raws li qhov loj ntawm lawv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib cais, kev tsim hluav taws xob lossis cov khoom siv hluav taws xob tsis zoo (xws li cov teeb liab me me, cov hluav taws xob sib txuas me me, cov khoom siv hluav taws xob electrolytic, thiab lwm yam. .) muab tso rau hauv cov dej ntws saum toj kawg nkaus ntawm cov cua txias (ntawm qhov nkag), cov khoom siv hluav taws xob los yog cov khoom siv hluav taws xob zoo (xws li cov hluav taws xob transistors, loj-scale integrated circuits, thiab lwm yam.) muab tso rau hauv feem ntau downstream ntawm cov cua txias.

Nyob rau hauv txoj kab rov tav, cov cuab yeej siv hluav taws xob siab tau npaj kom ze li sai tau rau ntawm ntug ntawm lub tshuab luam ntawv txhawm rau ua kom luv luv ntawm txoj kev hloov tshav kub; nyob rau hauv cov kev taw qhia ntsug, cov cuab yeej siv hluav taws xob siab tau npaj kom ze li sai tau rau saum lub tshuab luam ntawv txhawm rau txo qhov cuam tshuam ntawm cov cuab yeej no ntawm qhov kub ntawm lwm yam khoom siv thaum lawv ua haujlwm.

Lub tshav kub dissipation nyob rau hauv lub rooj tsavxwm luam tawm nyob rau hauv cov khoom siv feem ntau yog nyob ntawm huab cua txaus, yog li txoj kev khiav ntawm huab cua yuav tsum tau kawm thaum lub sij hawm tsim thiab cov khoom siv los yog cov ntawv luam tawm Circuit Board yuav tsum tau teeb tsa kom tsim nyog. Huab cua ntws ib txwm nyiam ntws qhov twg tsis muaj qhov tsis kam, yog li thaum teeb tsa cov khoom siv ntawm lub rooj tsav xwm luam tawm, tsis txhob tawm hauv qhov khoob loj hauv ib cheeb tsam. Tib yam yuav tsum tau them nyiaj rau kev teeb tsa ntawm ntau daim ntawv luam tawm hauv lub tshuab ua tiav.

Cov cuab yeej siv tau zoo rau qhov kub thiab txias yog qhov zoo tshaj plaws nyob rau hauv cheeb tsam nrog qhov kub qis tshaj plaws (xws li hauv qab ntawm lub cuab yeej), tsis txhob tso ncaj qha rau saum lub tshuab hluav taws xob, thiab ntau yam khoom siv tau zoo tshaj plaws nteg tawm ntawm lub dav hlau kab rov tav.

Muab cov cuab yeej siv hluav taws xob ntau tshaj plaws thiab tsim hluav taws xob siab tshaj plaws nyob ze rau qhov chaw zoo tshaj plaws rau cov cua sov dissipation. Tsis txhob tso cov khoom siv hluav taws xob ntau dua rau ntawm cov ces kaum thiab ib ncig ntawm cov npoo ntawm cov ntawv luam tawm tshwj tsis yog tias muaj lub dab dej kub nyob ze nws. Thaum tsim hluav taws xob resistors, xaiv cov khoom siv loj dua qhov ua tau thiab kho qhov teeb tsa ntawm lub rooj tsavxwm kom muaj qhov chaw txaus rau cov cua sov.

Tsis txhob muaj qhov kub ntawm qhov kub thiab txias ntawm PCB thiab faib lub zog kom sib npaug li qhov ua tau ntawm PCB pawg thawj coj saib kom tswj tau qhov kub thiab txias ua haujlwm ntawm PCB nto. Feem ntau cov txheej txheem tsim kom ua tiav qhov kev faib tawm nruj dua yog qhov nyuaj dua, tab sis nco ntsoov kom tsis txhob muaj qhov hnyav dhau ntawm lub zog, kom tsis txhob tshwm sim kub dhau los cuam tshuam rau kev ua haujlwm ntawm tag nrho lub voj voog. Yog tias muaj, qhov kev ntsuam xyuas thermal efficiency ntawm cov ntawv luam tawm yog qhov tsim nyog, xws li thermal efficiency Performance index tsom software module tam sim no ntxiv rau qee tus kws tshaj lij PCB tsim software tuaj yeem pab cov neeg tsim qauv tsim qauv tsim hluav taws xob zoo.
