Thermal cuam tshuam thiab tsis kam ntawm advanced PCB tsim

Kev cuam tshuam cua sov yog ib qho tseem ceeb uas yuav tsum tau muab tshem tawm hauv PCB tsim. Nws tau xav tias cov khoom siv thiab cov khoom siv muaj qee qhov kub ntawm lub sijhawm ua haujlwm, tshwj xeeb tshaj yog cov cua sov tawm los ntawm cov khoom siv muaj zog dua yuav cuam tshuam rau cov cheeb tsam kub-rhiab heev. Yog hais tias cov thermal cuam tshuam tsis zoo, ces tag nrho cov hluav taws xob hluav taws xob yuav hloov.

Txhawm rau tiv thaiv kev cuam tshuam thermal, cov kev ntsuas hauv qab no tuaj yeem ua:

(1) Qhov chaw ntawm cov khoom cua sov

Tsis txhob muab tso rau ntawm lub rooj tsavxwm, nws tuaj yeem txav mus rau sab nraud ntawm rooj plaub, lossis nws tuaj yeem tsim los ua ib qho chaw ua haujlwm, muab tso rau ze ntawm ntug qhov uas nws yooj yim rau dissipate cua sov. Piv txwv li, lub tshuab hluav taws xob microcomputer, lub hwj chim amplifier raj txuas rau sab nraud ntawm rooj plaub, thiab lwm yam. Tsis tas li ntawd, cov khoom siv hluav taws xob loj thiab cov khoom siv hluav taws xob me me yuav tsum muab tso rau nyias.

(2) Kev tso cov khoom siv hluav taws xob siab

yuav tsum tau teem kom ze rau ntawm ntug li sai tau thaum lub board luam ntawv, thiab yuav tsum tau teem caij saum toj no lub board luam ntawv ntau npaum li sai tau nyob rau hauv txoj kev ntsug.

(3) Qhov chaw ntawm cov khoom siv ntsuas kub

Qhov ntsuas kub-rhiab heev yuav tsum tau muab tso rau hauv qhov chaw kub qis tshaj plaws. Tsis txhob tso nws ncaj qha saum lub tshuab cua sov.

(4) Kev npaj thiab airflow ntawm cov khoom siv

Tsis muaj kev cai tshwj xeeb. Feem ntau, cov khoom siv sab hauv siv dawb convection kom dissipate tshav kub, yog li cov khoom yuav tsum tau teem caij vertically; yog tias lub tshav kub raug yuam kom dissipate, cov khoom tuaj yeem teem caij horizontally. Tsis tas li ntawd, txhawm rau txhawm rau txhim kho cov txiaj ntsig ntawm cov cua sov, cov khoom uas tsis muaj dab tsi cuam tshuam nrog lub hauv paus ntsiab lus ntawm Circuit Court tuaj yeem muab ntxiv los coj cov cua sov convection.
