Metal Core PCB kana MCPCB
Metal Core PCB (MCPCB) inozivikanwa seMetheta Backplane PCB kana Thermal PCB. Rudzi urwu rwePCB inoshandisa zvinhu zvesimbi panzvimbo yeiyo fr4 yeiyo base, iyo inopisa chinyadzo chechikamu chebhodhi.
Sezvo anozivikanwa kupisa anogadzirwa pabhodhi nekuda kweimwe chikonzero zvemagetsi zvikamu panguva yekushanda. Simbi inochinjisa kupisa kubva mudunhu redunhu uye ugadzirise iyo kune simbi core kana simbi yekupisa sink inotsigira uye yakakosha kuchengetedza chinhu.
Mune multiyer scB iwe uchawana yunifomu nhamba yezvikamu zvakagoverwa pane yesimbi core side. Semuenzaniso, kana iwe ukatarisa pane gumi nemaviri
McPCB kana Metal Core PCB inozivikanwawo se iCPB kana insured simbi PCB, IMS kana yakasarudzika simbi shuwa, simbi clad PCBS uye inopisa PCAM PCBS.
Kuti uwane iwe nekunzwisisa zviri nani isu tichazongoshandisa izwi rekuti simbi core Core PCB mudanho rese rino.
Chimiro chakakosha chesimbi core PCB inosanganisira zvinotevera:
Copper layer - 1oz.to 6oz. (zvakanyanya kujairika ndeye 1oz kana 2Z)
Circuit Layer
Dielectric layer
Sengesa Mask
Kupisa kunyura kana kupisa sink (metal core layer)
Mukana weMcPCB
Inobata
Cem3 kana fr4 haina kunaka pakuita kupisa. kana ichipisa
Iyo substrates inoshandiswa muPCBS ine zvisina kunaka maitiro uye inogona kukuvadza zvikamu zvePCB bhodhi. Ndipo apo simbi core pcbs dzinouya mukubatsira.
McPCB ine yakanakisa yekufambisa yekufambisa yekuchengetedza zvikamu kubva mukukuvara.
Kupisa Kukanganisa
Iyo inopa kutonhora kwakanyanya. Metal core PCBS inogona kusunungura kupisa kubva kuI IC zvakanyanya. Iyo inovandudza inotungamira layer inoendesa kupisa kune iyo simbi substrate.
Kuyera kugadzikana
Iyo inopa yakakwira dimensional kugadzikana kupfuura mamwe marudzi ePCBS. Mushure mekunge tembiricha ichishandurwa kubva pamadhigirii makumi matatu kuCelsius kusvika ku140-150 degrees celsius, iyo dimensional shanduko yeAluminium Metal Core ndeye 2.5 ~ 3%.
Kuderedza kukanganisa
Sezvo simbi core PCBs ine yakanaka kupisa kupaza uye inobata inonhuwirira, ivo havana kuderera kushatirisa nekuda kwekushomeka kupisa. Nekuda kwehunhu uhwu hwesimbi, PCBS ndiyo yekutanga sarudzo yekupa simba rekushandisa zvibodzwa izvo zvinoda yakakwira switching.
