Nkag siab qhov sib txawv ntawm txhuas pawg thawj coj thiab PCB

Aluminium board yog dab tsi

 

Aluminium board yog ib hom hlau raws tooj liab clad board nrog qhov ua kom zoo cua sov dissipation muaj nuj nqi. Feem ntau, tib lub vaj huam sib luag yog tsim los ntawm peb txheej, uas yog txheej txheej txheej (tooj liab ntawv ci), txheej rwb thaiv tsev thiab cov hlau puag txheej. Nws nquag nyob rau hauv cov khoom lag luam LED teeb pom kev zoo. Muaj ob sab, ib sab ntawm dawb yog welded coj tus pin, lwm sab yog txhuas xim, feem ntau yuav raug coated nrog cov cua sov conduction muab tshuaj thiab tiv tauj nrog cov khoom cua sov ua haujlwm. Kuj tseem muaj lub rooj tsavxwm ceramic thiab li.

 

PCB yog dab tsi

 

PCB pawg thawj coj saib feem ntau yog hais txog pawg thawj coj saib hauv Circuit Court. PCB (PCB board), tseem hu ua PCB, yog tus muab cov hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob. Nws tau tsim kho rau ntau tshaj 100 xyoo; Nws cov qauv yog mas qhov kev tsim qauv; Qhov zoo tseem ceeb ntawm kev siv Circuit Board yog txo cov kev ua yuam kev ntawm cov xov hlau thiab kev sib dhos ntau, thiab txhim kho qib automation thiab kev ua haujlwm ntawm tus nqi.

 

Raws li tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm lub rooj sib txig hauv Circuit Court, nws tuaj yeem muab faib ua cov vaj huam sib luag, muab ob daim txiag, plaub-txheej board, rau-txheej board thiab lwm lub rooj tsav xwm multilayer. Txij li thaum luam tawm Circuit board tsis yog cov khoom dav dav, nws yog me ntsis tsis meej pem nyob rau hauv lub ntsiab txhais ntawm lub npe. Piv txwv li, cov niam ntawv rau lub khoos phis tawm ntawm tus kheej yog hu ua niam daim hlau, tab sis tsis ncaj qha hu ua Circuit Court board. Txawm hais tias muaj Circuit Court board nyob hauv pawg thawj coj, nws tsis zoo li qub, yog li nws tsis tas yuav hais tib yam thaum ntsuas kev lag luam. Piv txwv li, vim tias muaj IC qhov khoom ntawm lub rooj tsav xwm hauv Circuit Court, xov xwm tshaj tawm nws hu ua nws pawg tsav tsheb IC, tab sis qhov tseeb, nws tsis sib npaug nrog cov ntawv luam tawm Circuit Circuit Peb feem ntau xa mus rau cov ntawv luam tawm Circuit Circuit li tsis muaj pawg thawj coj saib - uas yog, lub rooj tsav xwm hauv Circuit Court tsis muaj lub ntsiab.

 

Qhov sib txawv ntawm txhuas pawg thiab PCB pawg thawj coj saib

 

Rau qee tus neeg koom tes me uas nyuam qhuav koom nrog pawg lag luam txhuas pawg, yuav muaj cov lus nug zoo li no. Ntawd yog, dab tsi yog qhov sib txawv ntawm aluminium board thiab PCB board. Rau lo lus nug no, ntu nram qab no yuav qhia koj raws nraim li cas sib txawv nruab nrab ntawm ob?

 

PCB lub rooj tsavxwm thiab aluminium board yog tsim raws li qhov yuav tsum tau ua ntawm PCB. Tam sim no, lub txhuas raws PCB pawg thawj coj saib hauv kev ua lag luam yog feem ntau ib leeg txhuas lub rooj tsavxwm. PCB pawg thawj coj saib yog ntau hom, txhuas pawg yog tsuas yog ib hom PCB board, nws yog txhuas raws hlau phaj. Vim tias nws cov thermal conductivity zoo, nws feem ntau siv hauv kev lag luam LED.

 

PCB pawg thawj coj saib feem ntau yog tooj liab pawg, uas tseem muab faib ua ib pawg thiab ob tog vaj huam sib luag. Cov khoom siv nruab nrab ntawm ob yog pom tseeb sib txawv. Cov khoom tseem ceeb ntawm txhuas pawg yog phaj txhuas, thiab cov khoom tseem ceeb ntawm PCB pawg thawj coj yog tooj. Aluminium board yog tshwj xeeb rau nws cov khoom siv PP. Lub tshav kub dissipation yog qhov zoo heev. Tus nqi kuj tseem kim

 

Piv nrog ob hauv cov cua sov ua kom sov, kev ua tau zoo ntawm txhuas pawg thawj coj saib hauv tshav kub dissipation zoo dua li ntawm pawg thawj coj PCB, thiab nws cov thermal conductivity yog qhov txawv ntawm PCB, thiab tus nqi ntawm aluminium board yog tus nqi kim.
