Aluminium Substrate Khoom Composition

txheej txheej

Cov txheej hauv Circuit Court (feem ntau yog siv electrolytic tooj liab ntawv ci) yog etched los ua ib lub voj voog luam tawm rau kev sib dhos thiab kev sib txuas ntawm cov khoom siv. Piv nrog rau cov tsoos FR-4, nrog tib lub thickness thiab tib txoj kab dav, aluminium substrate tuaj yeem nqa tau ntau dua tam sim no.

Kev sib piv ntawm lub peev xwm nqa tam sim no ntawm aluminium substrate thiab FR-4 tooj liab ntawv ci

Rwb thaiv tsev

Cov txheej txheej insulating yog cov thev naus laus zis tseem ceeb ntawm aluminium substrate, uas feem ntau ua haujlwm ntawm kev sib txuas, rwb thaiv tsev thiab hluav taws xob conduction. Aluminium puag rwb thaiv tsev txheej yog qhov loj tshaj plaws thermal thaiv nyob rau hauv lub zog module qauv. Qhov zoo dua cov thermal conductivity ntawm cov txheej insulating, qhov ntau conducive mus rau lub diffusion ntawm tshav kub generated thaum lub sij hawm ua hauj lwm ntawm lub ntaus ntawv, thiab ntau conducive kom txo tau lub khiav hauj lwm kub ntawm lub ntaus ntawv, thiaj li mus cuag lub hom phiaj ntawm nce lub hwj chim load. ntawm cov module, txo qhov ntim, ua kom lub neej ntev, thiab txhim kho lub zog tso zis. .

hlau puag

Cov hlau twg yog siv rau cov insulating hlau substrate nyob ntawm qhov kev txiav txim siab ntawm thermal expansion coefficient, thermal conductivity, lub zog, hardness, hnyav, deg lub xeev thiab tus nqi ntawm cov hlau substrate.

Feem ntau hais lus, xav txog cov xwm txheej ntawm tus nqi thiab kev ua haujlwm, aluminium phaj yog qhov kev xaiv zoo tshaj plaws. Cov ntawv xaiv aluminium yog 6061, 5052, 1060 thiab lwm yam. Yog tias muaj cov kev xav tau rau cov thermal conductivity ntau dua, cov khoom siv kho tshuab, cov khoom siv hluav taws xob thiab lwm yam khoom tshwj xeeb, cov phaj tooj liab, stainless hlau daim hlau, hlau daim hlau thiab silicon steel daim hlau kuj tseem siv tau.
