Aluminium alloy substrate yog hlau tshwj xeeb substrate, vim nws zoo thermal conductivity, dissipation thaum tshav kub, hluav taws xob rwb thaiv tsev kev ua tau zoo thiab kev siv tshuab ua haujlwm, dav siv hauv cov txheej txheem ntau lawm ntawm cov chaw tsim hluav taws xob, cov aluminium alloy substrate tuaj yeem faib ua peb txheej, feem rau Circuit Court txheej (tooj liab ntawv ci), rwb thaiv tsev txheej thiab puag hlau. Aluminium substrate pcb yog dav siv hauv LED, cua txias, tsheb, lub qhov cub, hluav taws xob, txoj kev teeb, lub zog loj thiab lwm yam.

Vim li cas aluminium substrate thiaj li siv dav hauv cov khoom lag luam siab? Thermal nthuav dav kev ua tau zoo, kev nyab xeeb ruaj khov, kev kub siab thiab lwm yam khoom ua rau txhuas txheej ua kom tau raws li cov khoom lag luam siab dua.With cov teeb meem no, nrog YMS kev ua haujlwm aluminium substrate manufacturers ua ke kom nkag siab Cov.

Tam sim no cia peb qhia cov khoom muaj feem xyuam ntawm aluminium substrate

1. Thaum tshav kub kub dissipation: tam sim no, ntau txheej ob chav phaj, ntau txheej phaj loj ntom ntom nti, muaj zog, hluav taws kub cua sov tsis yooj yim.Qhov luam ntawv phaj substrate xws li FR4, CEM3 yog cov coj nrog kev ua tsis zoo thermal conductivity, rwb thaiv tsev txheej txheej thiab cov cua sov tsis zoo. .Tsis txhob tshem tawm cov cua kub hauv zos ntawm cov khoom siv hluav taws xob, ua rau muaj qhov kub thiab txias tsis zoo ntawm cov khoom siv hluav taws xob, thiab txhuas txheej txheej tuaj yeem daws cov teeb meem ntawm cov cua sov ua kom tsis sov.Thov ntxiv rau txhuas txheej, tooj liab substrate kub dissipation kuj tshwj xeeb zoo, tab sis tus nqi yog kim.

2. Cov qauv ruaj khov: txhuas raws cov ntawv luam tawm, pom tseeb ruaj khov dua li qhov loj ntawm insulating cov ntawv luam tawm board.Qhov aluminium substrate phaj thiab sandwich phaj yog rhuab los ntawm 30 ℃ txog 140 ~ 150 ℃, thiab qhov ntau thiab tsawg yog 2.5 ~ 3.0%.

3. Cov cua sov nthuav dav thiab txias txias yog qhov sib xws ntawm cov khoom, thiab cov coefficient ntawm thermal nthuav tawm ntawm cov khoom sib txawv yog txawv.Txhais txheej txheem luam ntawv tuaj yeem daws cov teeb meem ntawm kev kub tawm, txo cov cua sov thiab txias txias ntawm ntau yam ntawm cov ntawv luam tawm lub rooj tsavxwm, txhim kho cov kav ntev thiab kev ntseeg tau ntawm lub tshuab tag nrho thiab cov khoom siv hluav taws xob.Piv txwv tshwj xeeb SMT (nto lub rooj sib txoos thev naus laus zis) thermal expansion thiab txias shrinkage teeb meem.

4. Lwm cov laj thawj: aluminium raws li cov ntawv luam tawm hauv Circuit Court, tiv thaiv cov nyhuv, hloov pob zeb tawg yooj yim, kev ntseeg tau zoo ntawm cov txheej txheem saum npoo; ntawm cov khoom lag luam; Txo cov nqi tsim khoom, txo kev siv zog.

Qhov saum toj no yog vim li cas vim li cas aluminium substrate tau dav siv, Kuv vam tias nws yuav pab tau rau koj.Peb tau los ntawm Tuam Tshoj tus txhuas puas khoom lag luam khoom - YMS Technology Co., Ltd. Txais tos tham!
