Yuav Tsim Cov Qauv Ntshav Sov Ntawm PCB

PCB Circuit Board board dissipation tsim kev txawj ib qho: qhov tseem ceeb ntawm kev tsim thermal

Cov hluav taws xob hluav taws xob tau siv los ntawm cov khoom siv hluav taws xob thaum ua haujlwm, xws li RF lub zog ua kom muaj zog, FPGA nti thiab cov khoom siv fais fab, feem ntau hloov mus rau hauv cov cua sov tshwj tsis yog rau cov haujlwm ua haujlwm tau zoo.Qhov tshav kub uas tsim los ntawm cov khoom siv hluav taws xob ua rau sab hauv qhov kub nce sai. Yog tias cov cua sov tsis tawm nyob rau lub sijhawm, cov khoom siv yuav txuas ntxiv kom sov, thiab cov cuab yeej yuav ua tiav vim qhov kub dhau, thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob yuav txo qis. thaj tsam, thiab muaj kev cuam tshuam loj heev rau kev ntseeg tau ntawm cov khoom siv kub nce. Yog li, nws yog qhov tseem ceeb heev kom kawm qhov qauv tsim thermal.

Xov tooj cua-kwv tij muaj ntoo, yog li koj tuaj yeem txias?

Rau cov cua sov ua kom sov ntawm pawg thawj coj PCB yog qhov txuas tseem ceeb heev, yog li dab tsi yog qhov ua kom sov ua kom sov ntawm pawg thawj coj PCB, cia' s sib tham ua ke.

Rau cov khoom siv hluav taws xob, qee qhov nqi ntawm cov cua sov yuav tsim tawm thaum lub sijhawm ua haujlwm, yog li nce sai ntawm cov ntsuas kub ntawm sab hauv. Yog tias cov cua sov tsis tawm nyob rau hauv lub sijhawm, cov khoom siv yuav txuas ntxiv ua kom sov, cov cuab yeej yuav ua tiav vim qhov kub dhau, thiab kev ua tau zoo ntawm cov khoom siv hluav taws xob yuav poob qis.Yog li ntawd, nws tseem ceeb heev kom muaj lub zoo cua sov ua kom sov. kev kho mob rau ntawm Circuit Court board.

PCB cua txias tsim cov txheej txheem 2: PCB kub sawv los tshuaj ntsuam

Qhov ncaj qha ua rau PCB qhov kub nce siab yog qhov muaj hluav taws xob hauv Circuit Court dissipation pab kiag li lawm, thiab lub hwj chim hluav taws xob ntawm cov khoom siv hluav taws xob sib txawv, thiab qhov kub hloov pauv nrog lub zog hluav taws xob.

Ob qhov tshwm sim ntawm qhov kub thiab txias hauv cov ntawv luam tawm:

(1) Qhov ntsuas kub hauv cheeb tsam lossis thaj tsam kub nce siab;

(2) Kev kub ceev hauv lub sijhawm luv luv lossis lub sijhawm kub nce siab dua.Qhov hluav taws xob siv hluav taws xob ntau ntawm PCB feem ntau txheeb xyuas los ntawm cov hauv qab no.

2.1 Hluav taws xob siv hluav taws xob

(1) Kev tshuaj xyuas lub zog siv rau ib cheeb tsam;

(2) Tshawb xyuas lub zog siv hluav taws xob faib ntawm PCB board.

2.2 Cov qauv ntawm cov ntawv luam tawm

(1) Qhov loj me ntawm daim txiag luam ntawv;

(2) Cov ntawv luam tawm cov ntawv.

2.3 Txoj kev teeb tsa ntawm cov ntawv luam tawm

(1) hom kev teeb tsa (xws li kev teeb tsa ntsug, kev teeb tsa kab rov tav);

(2) Sealing mob thiab kom deb li cas ntawm cas.

2.4 thermal hluav taws xob

(1) Hluav taws xob tawg rau ntawm cov nplaim hluavtaws luam tawm;

(2) Qhov kub hloov sib txawv ntawm cov ntawv luam tawm thiab cov npoo uas nyob ib sab thiab lawv cov cua kub kiag li

2.5 kev sib sau thaum tshav kub

(1) Nruab ib lub radiator;

(2) Kev ua ntawm lwm cov qauv teeb tsa.

2.6 convection tshav kub

(1) Ntuj convection;

(2) yuam kev txias convection.

Kev ntsuam xyuas ntawm cov ntsiab lus saum toj no yog txoj hauv kev zoo los daws qhov kub nce siab ntawm cov ntawv luam tawm. Cov xwm txheej no feem ntau cuam tshuam thiab vam khom rau ib qho khoom lag luam thiab cov kab ke. Feem ntau ntawm cov xwm txheej yuav tsum tau tshawb xyuas raws li qhov xwm txheej tiag tiag.
