Hlau Core PCB lossis MCPCB
Hlau Core PCB (MCPCB) yog lub npe hu ua Hlau Cupbant lossis Thermal PCB. Hom PCB no siv cov khoom siv hlau tsis yog fr4 rau nws lub hauv paus, lub tshav kub seem ntawm pawg thawj coj saib.
Raws li tau paub cov cua kub yog tsim rau ntawm lub rooj tsavxwm rau qee qhov laj thawj hluav taws xob thaum ua haujlwm. Hlau hloov hluav taws xob los ntawm cov Circuit Court Board thiab redirects nws mus rau hlau cov tub ntxhais lossis cov tshav kub lub dab dej rov qab thiab cov khoom seem.
Nyob rau hauv ib multilayer pcb koj yuav pom ib tus naj npawb ntawm cov khaubncaws sab nraud povtseg muab faib rau ntawm cov hlau tseem ceeb. Piv txwv li, yog tias koj saib ntawm 12-txheej pcb, koj yuav pom rau txheej rau saum thiab rau txheej hauv qab, hauv nruab nrab yog cov hlau txheem.
MCPCB lossis hlau tseem ceeb PCB lossis insulated hlau pcb, ims lossis insulated hlau subtrates, hlau clad pcbs thiab thermal clad PCbs.
Rau koj kom nkag siab zoo dua peb yuav tsuas yog siv lub sij hawm hlau ntaus pcb thoob plaws kab lus no.
Cov qauv yooj yim ntawm cov hlau corecb pcb suav nrog cov hauv qab no:
Tooj liab txheej - 1oz.to 6oz. (Feem ntau cov yog 1oz lossis 2oz)
Circuit Court Txheej
Dielectric txheej
Taus Daim Npog
Thaum tshav kub kub dab dej lossis cov dab dej kub (txheej hlau)
Kom zoo rau MCPCB
Thermal conductivity
Cem3 lossis FR4 tsis zoo rau kev ua kom sov. Yog kub
Cov substrates siv nyob rau hauv PCBs muaj kev ua haujlwm tsis zoo thiab tuaj yeem ua kev puas tsuaj ntawm tus PCB Board. Ntawd yog thaum hlau tseem ceeb ntawm cov neeg sib xyaw ua ke tuaj ua ke.
MCPCB muaj cov thermal zoo heev los tiv thaiv cov khoom sib raug zoo.
Thaum tshav sov tsis kam
Nws muab cov peev xwm cua txias zoo heev. Hlau num tub ntxhais PCBs tuaj yeem cuam tshuam tshav kub los ntawm ib lub icy zoo heev. Thermally qhia txheej ces hloov cov cua sov mus rau cov hlau substrate.
Nplai stability
Nws muaj ntau dua qhov ruaj khov dua li lwm hom PCBs. Tom qab qhov ntsuas kub tau hloov los ntawm 30 degrees Celsius rau 140-150 degrees Celsius, qhov kev hloov pauv ntawm tus ntxhais txhuas yog 2.5 ~ 3%.
Txo cov distortion
Txij li ntawm cov hlau tseem ceeb muaj cov cua sov tsis txaus thiab thermal conductivity, lawv tsis tshua muaj zog rau deformation vim muaj cua sov. Vim tias cov xeeb ceem ntawm cov hlau tseem ceeb, PCBs yog thawj qhov kev xaiv rau cov khoom siv hluav taws xob uas xav tau siab hloov.
