Taw qhia ntawm MCPCB

MCPCB yog qhov luv ntawm Cov Hlau Tub ntxhais PCBs, suav nrog txhuas hauv PCB, tooj liab raws PCB thiab hlau raws PCB.

Aluminium based board yog hom ntau hom. Cov khoom siv hauv paus muaj nrog aluminium core, tus qauv FR4 thiab tooj liab. Nws nta thermal clad txheej uas dissipates tshav kub nyob rau hauv tus qauv siv tau zoo thaum ua kom txias. Tam sim no, Aluminium Raws li PCB tau suav hais tias yog kev daws rau lub zog loj. Txhuas nyob rau hauv lub rooj tsav khoom tuaj yeem hloov kho kom zoo li qub ceramic raws li lub rooj tsavxwm, thiab aluminium muab lub zog thiab kav ntev rau cov khoom uas cov ceramic ua tsis tau.

Tooj liab substrate yog ib qho ntawm cov khoom kim tshaj plaws hlau, thiab nws cov thermal conductivity yog ntau lub sij hawm zoo dua li ntawm cov txhuas ntawm cov hluav taws xob thiab cov hlau. Nws yog tsim rau qhov ua tau zoo tshaj plaws ua kom muaj cua sov dissipation ntawm high zaus Circuit Court, Cheebtsam hauv cov cheeb tsam nrog kev sib txawv hauv qhov kub thiab tsawg kub thiab ntsuas cov khoom sib txuas lus.

Thermal rwb thaiv tsev txheej yog ib qho ntawm cov khoom tseem ceeb ntawm cov tooj liab substrate, yog li lub thickness ntawm tooj liab ntawv ci feem ntau yog 35 m-280 m, uas tuaj yeem ua tiav lub zog muaj peev xwm tam sim no. Piv nrog rau aluminium substrate, tooj liab substrate tuaj yeem ua tiav kom zoo dua cov cua sov ua kom tsis muaj zog, yog li ua kom muaj kev ruaj khov ntawm cov khoom.

Tus qauv ntawm Aluminium PCB

Ntawv Txheej Txheem Tooj Liab

Lub voj voos tooj liab txheej txheej yog tsim kho thiab tsim kom tau los ua daim ntawv luam tawm, tus txheej txheem aluminium tuaj yeem nqa tam sim no ntau dua li qub tuab FR-4 thiab tib txoj kab dav.

Insulating Txheej

Cov txheej insulating yog cov thev naus laus zis ntawm lub txhuas txheej, uas yog feem ntau ua cov haujlwm ntawm rwb thaiv tsev thiab kev ua kom kub. Aluminium substrate insulating txheej yog qhov loj tshaj plaws ntawm tshav kub thaiv hauv cov qauv hluav taws xob. Qhov zoo dua ntawm cov thermal conductivity ntawm insulating txheej, qhov ua tau zoo dua nws yog txhawm rau txhawm rau muab cov cua sov tsim tawm thaum lub sijhawm ua haujlwm ntawm lub cuab yeej, thiab qis dua qhov kub ntawm cov twj,

Hlau substrate

Dab tsi ntawm cov hlau peb yuav xaiv raws li cov kab hlau insulating?

Peb yuav tsum xav txog lub thermal expansion coefficient, thermal conductivity, lub zog, tawv tawv, qhov hnyav, lub xeev qhov chaw thiab tus nqi ntawm cov hlau txig.

Nquag, aluminium yog qhov sib piv me dua li tooj liab. Muaj cov khoom siv aluminium yog 6061, 5052, 1060 thiab lwm yam. Yog tias muaj cov kev xav tau ntau dua rau cov thermal conductivity, cov cuab yeej lub zog, cov khoom siv hluav taws xob thiab lwm yam khoom tshwj xeeb, tooj liab tooj liab, daim hlau stainless, hlau daim hlau thiab silicon steel daim hlau kuj tseem siv tau.
