Thaum tshav kub kub tsim yog ib qho teeb meem uas yuav tshwm sim thaum lub sijhawm ua haujlwm ntawm PCBA. Thaum cov khoom siv hluav taws xob ua haujlwm tsis tu ncua, hluav taws xob hluav taws xob tau hloov pauv mus rau hauv tshav kub. Yog tias cov cua sov tsis tuaj yeem cuam tshuam rau lub sijhawm, qhov kub thiab txias ntau dhau yuav ua rau kev ua haujlwm tsis zoo, kev sib tsoo hluav taws xob, lossis txawm tias muaj kev puas tsuaj mus tas li rau cov chips thiab lwm yam tseem ceeb. Yog li ntawd, kev tswj xyuas thermal tau dhau los ua qhov kev sib txuas tseem ceeb uas ntau lub tuam txhab tsom mus rau, tshwj xeeb tshaj yog rau siab - zog thiab siab - cov khoom siv thauj khoom.
Muaj ntau yam kev daws teeb meem rau PCBA tshav kub dissipation hauv kev lag luam. Txoj kev uas feem ntau yog siv cov thermal conductive muab tshuaj txhuam thiab txuas cov dab dej kub rau ntawm qhov siab -cov khoom siv hluav taws xob xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Cov ntaub ntawv thermal interface tuaj yeem txo cov thermal tsis kam thiab hloov cov cua sov sai sai. Rau cov khoom siv compact uas tsis muaj qhov chaw sab hauv, cov tuam txhab tsim khoom yuav siv tooj liab- puv PCB boards thiab optimized tooj liab foil layout los txhim kho cov cua sov hauv ntuj.
Hauv cov txheej txheem tsim khoom, cov txheej txheem cov ntsiab lus tseem cuam tshuam rau kev ua kom sov dissipation. Qhov tsim nyog cov qauv tsim kom tsis txhob sib sau cov cua sov hauv ib cheeb tsam me. Tswj tau qhov kub thiab lub sijhawm tiv thaiv kev puas tsuaj rau cov khoom siv los ntawm overheating. Rau PCBA siv rau hauv cov khoom siv thiab cov khoom siv sab nraum zoov uas khiav ib ncig ntawm lub moos, cov chaw tsim khoom kuj tseem yuav tsim cov qauv cua los yog phim cov kiv cua txias me me.
Txawv daim ntawv thov scenarios muaj txawv thermal tsim qauv. High- cov cuab yeej siv computer kawg thiab cov khoom siv hluav taws xob ua haujlwm tau muab tso rau hauv cov kev cai nruj tshaj plaws rau kev tswj qhov kub thiab txias. Nrog rau cov khoom siv hluav taws xob hloov mus rau lub zog siab dua thiab kev sib koom ua ke ntau dua, kev tswj xyuas thermal thev naus laus zis tau hloov kho tas li. Nws tau maj mam dhau los ua qhov taw qhia tseem ceeb los ntsuas qhov kev paub txog lub zog ntawm PCBA cov tuam txhab.
