Hlau Core PCB los yog MCPCB
Hlau Core PCB (MCPCB) yog lub npe hu ua Hlau Backplane PCB lossis Thermal PCB.Hom PCB no siv cov khoom siv hlau es tsis txhob siv FR4 rau nws lub hauv paus, cov dab dej kub ntawm lub rooj tsavxwm.
As paubThaum tshav kub kub yog tsim rau ntawm lub rooj tsavxwm vim qee yam khoom siv hluav taws xob thaum ua haujlwm.Hlau hloov hluav taws xob los ntawm lub rooj tsav xwm Circuit Court thiab redirects nws mus rau Hlau core lossis hlau kub dab dej thaub qab thiab cov ntsiab lus txuag Element.
Nyob rau hauv ib tug multilayer PCB koj yuav pom ib tug sib xws ntawm cov khaubncaws sab nraud povtseg ntawm cov hlau core sab.Piv txwv li, yog tias koj saib ntawm 12-txheej PCB, koj yuav pom 6 txheej rau sab saum toj thiab rau txheej hauv qab, hauv nruab nrab yog cov tub ntxhais hlau.
MCPCB lossis Hlau Core PCB Kuj hu ua ICPB lossis Insulated Hlau PCB, IMS lossis Insulated Hlau Substrates, Hlau Clad PCBs thiab Thermal Clad PCBs.
Flos yog koj Kom nkag siab zoo dua peb tsuas yog siv lub sij hawm hlau core PCB thoob plaws hauv kab lus no.
Lub hauv paus qauv ntawm ib tug hlau core PCB muaj xws li cov hauv qab no:
Copper Txheej - 1oz.to 6oz.(feem ntau yog 1oz lossis 2oz)
txheej txheej
Dielectric txheej
Solder daim npog qhov ncauj
Kub dab dej los yog dab dej kub (hlau core txheej)
Qhov zoo rau MCPCB
Thermal conductivity
CEM3 lossis FR4 tsis zoo ntawm kev ua cua sov.yog kub
Cov substrates siv hauv PCBs muaj kev ua haujlwm tsis zoo thiab tuaj yeem ua rau cov khoom ntawm PCB board puas.Qhov ntawd yog thaum hlau tub ntxhais PCBs los ua ke.
MCPCB muaj cov thermal conductivity zoo heev los tiv thaiv cov khoom los ntawm kev puas tsuaj.
Hnoj dissipation
Nws muab lub peev xwm txias txias zoo heev.Cov tub ntxhais hlau PCBs tuaj yeem tso cua sov los ntawm IC zoo heev.Cov txheej thermally conductive ces hloov cov cua sov mus rau cov hlau substrate.
Scale stability
Nws muaj kev ruaj ntseg zoo dua li lwm hom PCBs.Tom qab qhov kub thiab txias tau hloov ntawm 30 degrees Celsius mus rau 140-150 degrees Celsius, qhov loj me ntawm aluminium hlau core yog 2.5 ~ 3%.
Rqhia distortion
Txij li cov tub ntxhais hlau PCBs muaj cov cua kub zoo thiab cov thermal conductivity, lawv tsis tshua muaj kev deformation vim yog vim cua sov.Vim yog cov yam ntxwv ntawm cov tub ntxhais hlau no, PCBs yog thawj qhov kev xaiv rau cov ntawv thov hluav taws xob uas xav tau kev hloov pauv siab.
