Yam ntxwv, qauv thiab kev ua haujlwm ntawm txhuas yam khoom
LED teeb meem yog qhov teeb meem tshaj plaws ntawm cov tub luam LED, tab sis tuaj yeem siv txhuas phaj, vim cov txheej txheem thermal thermal conductivity yog siab, zoo cua sov dissipation, ua tau zoo xa hluav taws xob sab hauv. Aluminium phaj yog ib cim tshwj xeeb raws li CCL, nrog thermal conductivity, hluav taws xob rwb thaiv tsev thiab kev ua tiav txhua yam. Kev tsim qauv yuav tsum sim ua kom cov PCB nyob ze ntawm qhov txhuas puag, uas yog txo cov potting ib feem ntawm kev thermal ua haujlwm.
Ua ntej, cov yam ntxwv ntawm txhuas phaj
1. Siv tshuab fais fab (SMT);
2. Hauv qhov kev tsim khoom tsim ntawm thermal diffusion ntawm txoj kev kho kom zoo heev;
3. Txo cov khoom kub hauj lwm, ua kom cov khoom muaj zog thiab kev cia siab, ntxiv khoom lub neej;
4. Txo cov khoom loj, txo cov nqi kho vaj tse thiab sib dhos;
5. Hloov lub zwj hluav taws zas dawb, ua kom zoo dua qub.
Thib ob, cov qauv ntawm cov phaj txhuas
Aluminium-based CCL yog cov khoom siv hlau hlau ntawm cov khoom siv, los ntawm cov ntawv ci, thermal insulation txheej txheem thiab hlau substrate muaj pes tsawg leeg, nws cov qauv faib ua peb txheej:
Cireuitl.Layer Kab txheej : qhov sib npaug ntawm PCB CCL zoo tib yam, kab tooj khoob khoob khoob khov mus rau 10oz.
DielcctricLayer Rwb thaiv tsev: Kev rwb thaiv tsev yog ib txheej ntawm thermal cov hluav taws kub thermal rwb thaiv tsev khoom.
BaseLayer Base: yog ib qho hlau substrate, feem ntau yog txhuas lossis xaiv tau tooj. Aluminium-based CCL thiab cov tshuaj epoxy iav laminates thiab hais txog.
Circuit Court layers (piv txwv li, cov ntawv xov tooj tooj liab) feem ntau yog sib sau ua ib daim txiag luam tawm, yog li ntawd ntau yam ntawm cov khoom sib txuas nrog txhua yam, raws li kev quab yuam, lub circuit txheej yuav tsum muaj lub peev xwm loj uas tam sim no, uas yuav tsum siv cov tuab tuab , tuab ntawm 35 μ m ~ 280μm; thermal insulation txheej yog cov cuab yeej technology ntawm aluminium substrate, nws yog feem ntau muaj cov tshwj xeeb ceramic tshwj xeeb polymer pes tsawg leeg, thermal ua hauj, kev kawm viscoelastic, nrog rau kev muaj peev xwm kom kub laus, tuaj yeem cov neeg kho tshuab thiab thermal kev nyuab siab.
High-performance aluminium substrate thermal insulation txheej yog kev siv cov tshuab no, nws muaj cov thermal conductivity zoo thiab siab zog hluav taws xob rwb thaiv tsev zog; hlau substrate yog lub txhuas phaj kev txhawb zog, yuav tsum muaj cov thermal conductivity, feem ntau txhuas, Feem ntau kuj siv tau tooj hlau (uas yog lub tooj liab ua kom zoo dua thermal conductivity), tsim rau kev siv drilling, punching thiab txiav thiab lwm yam khoom siv. PCB cov ntaub ntawv muab piv nrog lwm cov ntaub ntawv tsis muaj txiaj ntsim zoo. Haum rau cov khoom siv hluav taws xob nto ntawm lub tshuab SMT daim duab. Tsis xav tau lub tshuab radiator, zoo heev txo qhov me me, zoo heev kub thoob, kev dim pa zoo nkauj thiab txhua yam khoom.
Kub khoom: tsis tshua muaj voltage sawb lub teeb , decorated teeb pom kev zoo bar , ntse sensor siab bay , High Bay , LED vaj huam sib luag nrog tus IP
