MCPCB Daim Ntawv Thov Txhim Kho Kev Ua Haujlwm thiab Kev Ntseeg ntawm UV LED

Hauv kev ua haujlwm ntawm UV LEDs, daim ntawv thov ntawm Hlau Core Printed Circuit Board (MCPCB) ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm, kev tswj xyuas thermal thiab kev ntseeg tau ntawm tag nrho cov khoom.

Thaum tshav kub kub Dissipation

MCPCB yog zoo heev nyob rau hauv tshav kub dissipation, ua kom pom kev ua tau zoo thiab ntev ntawm UV LED teeb. Cov khoom siv hlau ntawm MCPCB feem ntau yog ua los ntawm txhuas lossis tooj liab nrog cov thermal conductivity siab. Qhov tshwj xeeb thermal conductivity no tso cai rau cov cua sov tsim kom tawg sai sai, tiv thaiv cov cua sov thiab ua kom ntseeg tau tias cov cuab yeej ua haujlwm hauv qhov ntsuas kub zoo.

Txhim kho ntawm Thermal Conductivity

Lub thermal conductivity ntawm MCPCB yog kwv yees li 10 npaug ntawm FR4PCB. MCPCB pab ua kom muaj qhov sib txawv ntawm qhov kub thiab txias thiab txo qhov kev pheej hmoo ntawm qhov kub thiab txias ntawm qhov kub thiab txiasUV LED teeb.Yog li ntawd, lub teeb tuav lawv cov kev ua tau zoo thiab kev ntseeg siab txawm tias lub sijhawm ua haujlwm ntev.

Txhim kho kev ntseeg siab

MCPCB muaj ntau dua txhua yam muaj zog thiab thermal stability. Piv txwv li, cov coefficient ntawm thermal expansion (CTE) ntawm MCPCB tuaj yeem sib phim rau UV LEDs, txo qhov kev pheej hmoo ntawm kev ua haujlwm tsis zoo vim thermal mismatch. 

Hluav taws xob rwb thaiv tsev

MCPCB muab hluav taws xob rwb thaiv tsev ntawm cov tub ntxhais hlau thiab cov txheej hauv Circuit Court kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm UV LED systems. Cov txheej txheej dielectric feem ntau yog ua los ntawm cov ntaub ntawv xws li epoxy resin lossis thermally conductive fluid (TCF), uas muab siab tawg voltage thiab rwb thaiv tsev tsis kam. Qhov hluav taws xob rwb thaiv tsev no txo ​​qhov kev pheej hmoo ntawm luv luv Circuit Court lossis hluav taws xob nrov, tiv thaiv lub cev los ntawm kev puas tsuaj.

Kev ua tau zoo tshaj plaws

Los ntawm kev sib koom ua ke MCPCB, cov tuam txhab lag luam tuaj yeem ua kom zoo dua qhov kev ua tau zoo ntawm lawvUV LED cov khoom siv. Lub tshav kub dissipation thiab thermal conductivity ntawm MCPCB tso cai rau UV LED ua haujlwm ntawm qhov ua tau zoo tshaj plaws. Qhov kev ua tau zoo no ua kom pom tseeb UV cov zis, ua rau MCPCB zoo tagnrho rau ntau yam kev siv UV.
