Multi Layers MCPCB yog dab tsi?
Lub Hlau Core Printed Circuit Board (MCPCB)tseem hu ua thermal PCB lossis hlau thaub qab PCB, yog ib hom PCB uas muaj cov khoom siv hlau ua nws lub hauv paus rau lub tshav kub kis ntawm lub rooj tsavxwm. Cov hlau tuab (yuav luag ib txwm txhuas lossis tooj liab) yog npog 1 sab ntawm PCB. Cov tub ntxhais hlau tuaj yeem ua raws li cov hlau, ua nyob rau hauv nruab nrab qhov chaw los yog tom qab ntawm lub rooj tsavxwm. Lub hom phiaj ntawm lub hauv paus ntawm MCPCB yog los hloov cov cua sov kom deb ntawm cov khoom tseem ceeb ntawm lub rooj tsavxwm thiab mus rau qhov tsis tshua muaj qhov tseem ceeb xws li cov hlau heatsink rov qab lossis cov tub ntxhais hlau. Lub hauv paus hlau hauv MCPCB yog siv los ua lwm txoj hauv kev rau FR4 lossis CEM3 boards.
Cov tub ntxhais hlau luam tawm Circuit Board (MCPCB) tseem hu ua thermal PCB, suav nrog cov khoom siv hlau raws li nws lub hauv paus tsis zoo li cov tsoos FR4, rau lub tshav kub kis ntawm lub rooj tsavxwm. Thaum tshav kub kub tsim los ntawm qee cov khoom siv hluav taws xob thaum lub sijhawm ua haujlwm ntawm lub rooj tsavxwm. Lub hom phiaj ntawm cov hlau yog kom hloov cov cua sov no tawm ntawm cov khoom tseem ceeb ntawm lub rooj tsavxwm thiab mus rau qhov tsis tshua muaj qhov tseem ceeb xws li cov hlau heatsink backing lossis hlau core. Yog li, cov PCBs no yog qhov zoo rau kev tswj xyuas thermal.
Nyob rau hauv multilayer MCPCB, cov khaubncaws sab nraud povtseg yuav muab sib npaug ntawm txhua sab ntawm cov tub ntxhais hlau. Piv txwv li, nyob rau hauv 12-txheej board, cov tub ntxhais hlau yuav nyob rau hauv nruab nrab nrog 6 txheej nyob rau sab saum toj thiab 6 txheej nyob rau hauv qab.
MCPCBs kuj tseem hu ua insulated metallic substrate (IMS), insulated hlau PCBs (IMPCB), thermal clad PCBs, thiab hlau-clad PCBs. Hauv tsab xov xwm no, peb yuav siv lub npe MCPCB kom tsis txhob muaj qhov tsis meej pem.
MCPCBs yog tsim los ntawm cov txheej txheem thermal insulating, hlau daim hlau, thiab cov ntawv hlau tooj liab. Ntxiv cov txheej txheem tsim / cov lus pom zoo rau Hlau Core (Aluminium thiab Copper) Printed Circuit Boards muaj nyob rau ntawm kev thov; hu rau YMSPCB ntawm kell@ymspcb.com.lossis koj Tus Neeg Muag Khoom kom nug ntxiv.

Lub ntsiab yog vim li cas rau siv tooj liab puag boards
1. Zoo cua sov dissipation:
Ntawm tam sim no, ntau 2 pawg pawg thawj coj thiab multilayer cov laug cam muaj qhov kom zoo dua ntawm kev ceev thiab lub zog loj, tab sis cov cua sov emission nyuaj rau. Cov khoom siv PCB ib txwm muaj xws li FR4, CEM3 yog cov khoom siv hluav taws xob tsis zoo ntawm cov cua sov, rwb thaiv tsev nyob nruab nrab ntawm cov khaubncaws sab nraud povtseg, thiab cov cua kub tsis tuaj yeem tawm mus. Cov cua sov hauv cheeb tsam ntawm cov khoom siv hluav taws xob tsis tuaj yeem raug tshem tawm yuav ua rau muaj kev kub ntxhov ntawm cov khoom siv hluav taws xob. Tab sis qhov ua tau zoo thaum tshav kub kub dissipation kev ua tau zoo ntawm cov tub ntxhais hlau PCB tuaj yeem daws qhov teeb meem kub dissipation no.
2. Dimensional stability:
Cov tub ntxhais hlau PCB yog qhov tseeb ntau ruaj khov hauv qhov loj dua li cov ntawv luam tawm ntawm cov ntaub ntawv insulating. Aluminium puag board thiab aluminium sandwich board yog cua sov los ntawm 30 ℃ to 140 ~ 150 ℃, nws loj hloov ntawm 2.5 ~ 3.0%.
3. Lwm yam laj thawj:
Copper puag board muaj cov nyhuv shielding thiab hloov cov nkig ceramic substrate, yog li nws muaj peev xwm so assured siv nto mounting thev naus laus zis los txo qhov chaw zoo ntawm PCB. Copper puag board hloov lub radiator thiab lwm yam khoom, txhim kho lub tshav kub tsis kam thiab lub cev ua haujlwm ntawm cov khoom thiab nws txo cov nqi tsim khoom thiab cov nqi zog.
