daws cov teeb meem kev tswj xyuas thermal rau ntau lub PCBs, tshwj xeeb tshaj yog hauv cov ntawv thov hluav taws xob

Hauv tsab ntawv tshaj tawm no, peb yuav tshawb txog ntau lub tswv yim thiab cov tswv yim los daws cov teeb meem ntawm PCB thermal tswj cov teeb meem, nrog rau kev tsom mus rau kev siv hluav taws xob siab.

Kev tswj cua sov yog ib qho tseem ceeb ntawm kev tsim hluav taws xob, tshwj xeeb tshaj yog thaum nws los txog rau ntau lub PCBs ua haujlwm hauv cov ntawv siv hluav taws xob siab. Lub peev xwm ua tau zoo dissipate Circuit Court board tshav kub ua kom pom kev ua haujlwm zoo, kev ntseeg tau thiab kev ua haujlwm ntev ntawm cov khoom siv hluav taws xob.

Nrog rau 15 xyoo ntawm Circuit Board board kev paub, ib pab neeg muaj zog, advanced manufacturing technology thiab txheej txheem muaj peev xwm, raws li zoo raws li imported tag nrho automated ntau lawm cov cuab yeej thiab sai prototyping technology, Capel yog npaj txhij los pab koj kov yeej cov kev cov nyom. Peb cov kws tshaj lij thiab kev mob siab rau hauv kev tsav tsheb ua tiav ntawm cov neeg siv khoom lag luam thiab txeeb lub sijhawm tau ua rau peb muaj kev ntseeg siab hauv kev lag luam.

Thaum cuam tshuam nrog thermal tswj ntawm ntau lub PCBs, cov hauv qab no yuav tsum tau xav txog:

1. Kev xaiv cov khoom siv PCB:
Kev xaiv cov khoom siv ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas thermal. High thermal conductivity cov ntaub ntawv xws li hlau core PCBs pab dissipate tshav kub zoo. Tsis tas li ntawd, xaiv cov khoom siv nrog cov coefficient tsawg ntawm thermal expansion txo qhov kev pheej hmoo ntawm kev tiv thaiv tsis ua haujlwm vim thermal stress.

2. Thermal Design Guidelines:
Ua raws li cov txheej txheem tsim thermal tsim nyog yog qhov tseem ceeb rau kev ua kom sov kom zoo. Kev npaj ua tiav, suav nrog kev tso cov khoom tsim nyog, kev ua haujlwm ntawm cov kab hluav taws xob siab, thiab kev ua haujlwm thermal vias, tuaj yeem txhim kho tag nrho cov thermal kev ua tau zoo ntawm PCB.

3. Radiator thiab thermal ncoo:
Thaum tshav kub kub dab dej feem ntau yog siv los dissipate tshav kub los ntawm high-power Cheebtsam. Cov dab dej kub no muaj ntau dua qhov chaw tshav kub hloov chaw thiab tuaj yeem hloov kho kom tau raws li cov kev xav tau tshwj xeeb. Thermal pads, ntawm qhov tod tes, xyuas kom zoo dua thermal coupling ntawm cov khoom thiab cov dab dej kub, txhawb kom muaj cua sov dissipation.

4. Cov qhov txias txias:
Thermal vias ua lub luag haujlwm tseem ceeb hauv kev ua cua sov los ntawm PCB nto mus rau hauv qab txheej, xws li lub dav hlau hauv av. Qhov kev teeb tsa thiab qhov ntom ntom ntawm cov vias no yuav tsum tau ua tib zoo txiav txim siab txhawm rau txhim kho cov cua sov thiab tiv thaiv qhov kub kub.

5. Copper pouring thiab npaj:
Tsim kom zoo tooj liab pours thiab dav hlau ntawm PCB tuaj yeem txhim kho kev ua haujlwm thermal. Tooj liab yog cov thermal conductor zoo heev thiab tuaj yeem kis tau cov cua sov thoob plaws hauv lub rooj tsavxwm thiab txo qhov kub thiab txias. Siv cov tooj liab tuab rau cov kab hluav taws xob kuj tseem pab kom cov cua sov dissipate.

6. Thermal tsom xam thiab simulation:
Kev ntsuas cua sov thiab cov cuab yeej simulation ua rau cov neeg tsim qauv txheeb xyuas qhov kub thiab txias thiab ntsuas qhov ua tau zoo ntawm lawv cov tswv yim tswj thermal ua ntej theem tsim khoom. Cov cuab yeej no tuaj yeem kho cov qauv tsim thiab ua kom zoo dua thermal ua haujlwm.

Ntawm Capel, peb siv cov thev naus laus zis tsom xam thiab simulation cov txheej txheem los xyuas kom meej tias peb cov qauv PCB ntau qhov tuaj yeem ua tau.

tiv taus cov ntawv thov hluav taws xob siab thiab muaj peev xwm tswj xyuas thermal zoo.

7. Enclosure tsim thiab airflow:
Kev tsim ntawm qhov chaw kaw thiab kev tswj xyuas huab cua kuj tseem yog qhov tseem ceeb hauv kev tswj xyuas thermal. Ib rooj plaub uas tsim tau zoo nrog cov qhov tso tawm kom zoo thiab cov kiv cua tuaj yeem txhawb cov cua sov dissipation thiab tiv thaiv kom tsis txhob muaj cua sov, uas tuaj yeem tiv thaiv kev ua haujlwm tsis zoo thiab cov khoom tsis ua haujlwm.

Peb ntawm Capel muab kev daws teeb meem thermal tswj kev daws teeb meem rau ntau-circuit PCBs. Peb pab neeg muaj kev paub dhau los ua haujlwm nrog cov neeg siv khoom kom nkag siab txog lawv cov kev xav tau tshwj xeeb thiab tsim cov kev cai daws teeb meem uas daws lawv cov teeb meem thermal. Nrog peb cov cuab yeej tsim khoom siab heev thiab cov txheej txheem muaj peev xwm, peb ua kom cov qauv zoo tshaj plaws thiab kev ua tiav qhov project launches.

Hauv cov ntsiab lus, kev daws teeb meem kev tswj hwm thermal rau ntau lub PCBs, tshwj xeeb tshaj yog nyob rau hauv kev siv hluav taws xob siab, yuav tsum tau ua tib zoo xav txog ntau yam xws li kev xaiv cov khoom, thermal tsim cov txheej txheem, cov dab dej kub, thermal vias, tooj liab pours thiab dav hlau, thermal tsom xam, enclosure. Kev tsim thiab kev tswj hwm huab cua.Nrog rau ntau xyoo ntawm kev paub thiab kev siv thev naus laus zis, Capel npaj txhij los ua koj tus khub ntseeg siab hauv kev kov yeej cov kev cov nyom no. Tiv tauj peb hnub no los tham txog koj cov kev xav tau kev tswj xyuas thermal thiab qhib tag nrho cov peev txheej ntawm koj cov qauv siv hluav taws xob.
