I-Metal Core PCB okanye i-MCPCB
I-Metal Core PCB (MCPCB) yaziwa ngokuba yi-Metal Backplane PCB okanye i-Thermal PCB.Olu hlobo lwe-PCB lusebenzisa izinto zetsimbi endaweni ye-FR4 eqhelekileyo kwisiseko sayo, inxalenye yebhodi yokushisa.
As iyaziwaubushushu buveliswa ebhodini ngesizathu esithile Amacandelo e-Electronic ngexesha lokusebenza.I-Metal idlulisela ubushushu kwibhodi yesekethe kwaye iyibuyisele kwi-Metal core okanye i-metal heat sink backing kunye ne-key yokonga i-Element.
Kwi-PCB ye-multilayer uya kufumana inani elifanayo leeleya ezisasazwe kwicala elingundoqo lesinyithi.Umzekelo, ukuba ujonga kwi-PCB ene-12-layer, uya kufumana amaleko amathandathu phezulu kunye namaleko amathandathu ezantsi, embindini ngumbindi wentsimbi.
I-MCPCB okanye i-Metal Core PCB Ikwabizwa ngokuba yi-ICPB okanye i-Insulated Metal PCB, i-IMS okanye i-Insulated Metal Substrates, i-Metal Clad PCBs kunye ne-Thermal Clad PCBs.
Fokanye wena Ukuze uqonde ngcono siya kusebenzisa igama elithi metal core PCB kulo lonke eli nqaku.
Ulwakhiwo olusisiseko lwePCB engundoqo yentsimbi lubandakanya oku kulandelayo:
Uluhlu lweCopper - 1oz.to 6oz.(eyona ixhaphake kakhulu yi1oz okanye 2oz)
umaleko wesekethe
Umaleko weDielectric
Imaski yeSolder
Isinki yobushushu okanye isinki yobushushu (umaleko ongundoqo wesinyithi)
I-advanteji ye-MCPCB
I-Thermal Conductivity
I-CEM3 okanye i-FR4 ayilunganga ekuqhubeni ubushushu.ukuba kushushu
I-substrates ezisetyenziswa kwii-PCB zine-conductivity engalunganga kwaye zingonakalisa amacandelo ebhodi ye-PCB.Kulapho iiPCB ezingundoqo zesinyithi ziza luncedo.
I-MCPCB ine-conductivity egqwesileyo ye-thermal ukukhusela amacandelo kumonakalo.
Hyitya ukuchithwa
Inika umthamo obalaseleyo wokupholisa.I-Metal core PCB inokuphelisa ubushushu obuvela kwi-IC kakuhle kakhulu.Umaleko we-thermal conductive emva koko udlulisela ubushushu kwi-substrate yensimbi.
Uzinzo lwesikali
Inika uzinzo oluphezulu lwe-dimensional kunezinye iindidi ze-PCBs.Emva kokuba iqondo lobushushu litshintshile ukusuka kwi-30 degrees celcius ukuya kwi-140-150 degrees celcius, utshintsho lwe-dimensional ye-aluminium core yesinyithi yi-2.5 ~ 3%.
Rukukhuthaza ukugqwesa
Kuba iiPCB zentsimbi ezingundoqo zinokutshatyalaliswa kobushushu obulungileyo kunye ne-thermal conductivity, azithandeki kangako ekuguqulweni ngenxa yobushushu obubangelwayo.Ngenxa yolu phawu lwesiseko sesinyithi, iiPCBs zikhetho lokuqala lonikezelo lombane olufuna ukutshintshwa okuphezulu.
