Rau cov khoom siv hluav taws xob, qee qhov hluav taws xob tau tsim tawm thaum lub sijhawm ua haujlwm, kom qhov kub thiab txias ntawm cov khoom siv tau nce sai. Yog tias cov cua sov tsis tau ploj mus rau lub sijhawm, cov cuab yeej yuav ua kom sov ntxiv, thiab cov cuab yeej yuav poob vim overheating. Kev ntseeg ntawm cov khoom siv hluav taws xob Kev ua tau zoo yuav txo qis. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau ua ib tug zoo tshav kub dissipation kev kho mob ntawm lub Circuit Court board.

PCB tsim yog ib tug downstream txheej txheem uas ua raws li lub hauv paus ntsiab lus tsim, thiab qhov zoo ntawm tus tsim ncaj qha cuam tshuam rau cov khoom ua tau zoo thiab lub lag luam voj voog. Peb paub tias cov khoom ntawm PCB pawg thawj coj saib muaj lawv tus kheej qhov chaw ua haujlwm kub. Yog tias qhov no ntau dhau, kev ua haujlwm ntawm cov cuab yeej yuav raug txo los yog ua tsis tiav, ua rau muaj kev puas tsuaj rau lub cuab yeej. Yog li ntawd, qhov kub dissipation yog qhov tseem ceeb hauv kev tsim PCB.

Yog li, raws li tus kws tsim qauv PCB, peb yuav tsum ua li cas thiaj li ua kom sov so?

Lub tshav kub dissipation ntawm PCB muaj feem xyuam rau kev xaiv ntawm lub rooj tsavxwm, kev xaiv ntawm cov khoom, thiab cov txheej txheem ntawm cov khoom. Ntawm lawv, qhov kev teeb tsa ua lub luag haujlwm tseem ceeb hauv PCB tshav kub dissipation thiab yog ib feem tseem ceeb ntawm PCB tshav kub dissipation tsim. Thaum tsim cov layouts, engineers yuav tsum xav txog cov hauv qab no:

(1) Centrally tsim thiab nruab cov khoom siv hluav taws xob tsim hluav taws xob thiab hluav taws xob loj ntawm lwm lub rooj tsav xwm PCB, txhawm rau ua kom muaj kev sib cais nruab nrab ntawm qhov cua thiab cua txias kom tsis txhob muaj kev cuam tshuam nrog lub motherboard;

(2) Lub peev xwm kub ntawm PCB pawg thawj coj saib sib npaug. Tsis txhob tso cov khoom siv hluav taws xob siab nyob rau hauv ib qho kev xav. Yog tias nws tsis tuaj yeem zam tau, tso cov khoom luv luv ntawm cov cua ntws thiab ua kom cov cua txias txaus los ntawm qhov chaw siv hluav taws xob uas muaj zog;

(3) Ua kom lub tshav kub hloov mus kom luv li sai tau;

(4) Ua kom lub tshav kub hloov mus hla ntu kom loj li sai tau;

(5) Cov txheej txheem ntawm cov khoom siv yuav tsum tau coj mus rau hauv tus account qhov cuam tshuam ntawm cov hluav taws xob hluav taws xob nyob ib puag ncig. Thaum tshav kub kub rhiab qhov chaw thiab cov khoom (nrog rau cov khoom siv semiconductor) yuav tsum tau khaws cia kom deb ntawm qhov chaw sov lossis cais;

(6) Ua tib zoo saib rau tib qho kev taw qhia ntawm kev quab yuam cua thiab ntuj cua;

(7) Cov sub-boards ntxiv thiab cov cuab yeej cua tshuab yog nyob rau hauv tib txoj kev raws li qhov cua;

(8) Raws li qhov ua tau, ua kom qhov nqus tau thiab tso pa kom txaus;

(9) Cov cuab yeej cua sov yuav tsum tau muab tso rau saum cov khoom kom ntau li ntau tau, thiab yuav tsum tau muab tso rau ntawm cov cua ntws channel thaum muaj xwm txheej tso cai;

(10) Tsis txhob tso cov khoom uas muaj cua sov los yog siab tam sim no rau ntawm cov ces kaum thiab cov npoo ntawm PCB board. Txhim kho lub dab dej kub kom ntau li ntau tau, khaws nws kom deb ntawm lwm yam khoom, thiab xyuas kom meej tias cov cua kub dissipation channel tsis muaj kev cuam tshuam.
