Metal Core PCB MCPCB ranei
Metal Core PCB (MCPCB) Kei te mohiotia ko Metal Backplane PCB ranei Thermal PCB.Ko tenei momo PCB ka whakamahi i tetahi mea whakarewa hei utu mo te FR4 angamaheni mo tona turanga, te wahanga wera o te papa.
As e mohiotia anaka puta te wera i runga i te papa mo etahi take nga waahanga hiko i te wa e mahi ana.Ka whakawhitia te wera o te konganuku mai i te papa taiawhio, ka anga atu ki te matua whakarewa, ki te totohu wera whakarewa ranei me te Huanga penapena matua.
I roto i te PCB multilayer ka kitea e koe he maha o nga paparanga kua tohatohahia ki te taha matua whakarewa.Hei tauira, ki te titiro koe ki I runga i te 12-papa PCB, ka kitea e koe e ono nga papa o runga me nga papa e ono ki raro, kei waenganui ko te matua whakarewa.
MCPCB or Metal Core PCB Kei te mohiotia ano ko ICPB, ko te PCB Metal Insulated, IMS ranei, ko nga Taapapa Whakaata Whakaata, Ko nga PCB Whakakakahu Meera me nga PCB Whakaahua Ngawha.
Franei koe Mo te pai ake o te mohio ka whakamahia e matou te kupu PCB matua whakarewa puta noa i tenei tuhinga.
Ko te hanganga taketake o te PCB matua whakarewa ko enei e whai ake nei:
Apa parahi – 1oz.ki te 6oz.(ko te nuinga o te waa ko te 1oz, 2oz ranei)
paparanga ara iahiko
Paparanga dielectric
Kore kookiri
Totohu wera, totohu wera ranei (paparanga matua whakarewa)
He painga mo MCPCB
Te Whakawhitinga Ngawha
Ko te CEM3 me te FR4 kaore e pai ki te kawe wera.ki te wera
Ko nga taputapu e whakamahia ana i roto i nga PCB he ngoikore te kawe me te kino i nga waahanga o te papa PCB.Koinei te wa ka tae mai nga PCB matua whakarewa.
He pai te kawe waiariki a MCPCB hei tiaki i nga waahanga mai i te kino.
Hkai toreretanga
Ka whakarato i te kaha whakamahana pai.Ka taea e nga PCB matua whakarewa te whakakore i te wera mai i te IC.Ka whakawhitihia e te paparanga waiariki te wera ki te taputapu whakarewa.
Tauine pūmautanga
He nui ake te pumau o te ahu atu i era atu momo PCB.I muri i te huringa o te pāmahana i 30 nekehanga Celsius ki 140-150 nekehanga Celsius, te huringa ahu o te matua whakarewa konumohe ko 2.5 ~ 3%.
Rwhakakorikori
I te mea he pai te tohanga wera o nga PCB matua me te kawe waiariki, he iti ake te paheketanga na te wera o te wera.Na tenei ahuatanga o te matua whakarewa, ko nga PCB te kowhiringa tuatahi mo nga tono tuku hiko e hiahia ana kia huri teitei.
