Metal Core PCB e bolela thepa ea mantlha (ea motheo) bakeng sa PCB ke tšepe, eseng FR4 / CEM1-3 e tloaelehileng, joalo-joalo 'me hona joale tšepe e sebelisoang haholo bakeng sa moetsi oa MCPCB ke Aluminium, Copper le alloy ea tšepe. Aluminium e na le bokhoni bo botle ba ho fetisa mocheso le ho senya, empa leha ho le joalo e batla e le theko e tlaase; koporo e na le ts'ebetso e ntle le ho feta empa e batla e le theko e boima, 'me tšepe e ka aroloa ka tšepe e tloaelehileng le tšepe e sa hloekang. E thata ho feta aluminium le koporo ka bobeli, empa conductivity ea mocheso e tlase ho feta le tsona. Batho ba tla khetha lisebelisoa tsa bona tsa motheo / tsa mantlha ho latela ts'ebeliso ea bona e fapaneng.

Ka kakaretso, aluminium ke khetho e ntle ka ho fetisisa ea moruo ho nahanoa ka conductivity ea mocheso, ho tiea le litšenyehelo. Ka hona, lisebelisoa tsa motheo / tsa mantlha tsa Metal Core PCB tse tloaelehileng li entsoe ka aluminium. Khamphaning ea rona, haeba e se kopo e khethehileng, kapa lintlha, moelelo oa mantlha oa tšepe e tla ba aluminium, ebe MCPCB e tla bolela Aluminium Core PCB. Haeba o hloka Copper Core PCB, Steel Core PCB, kapa Stainless steel core PCB, o lokela ho eketsa lintlha tse khethehileng ho taka.

Ka linako tse ling batho ba tla sebelisa khutsufatso ea "MCPCB", sebakeng sa lebitso le felletseng joalo ka Metal Core PCB, kapa Metal Core Printed Circuit Board. Hape ho sebelisitsoe lentsoe le fapaneng le bolela motheo / motheo, kahoo o tla bona le mabitso a fapaneng a Metal Core PCB, joalo ka  Metal PCB, Metal Base PCB, Metal Backed PCB, Metal Clad PCB le Metal Core Board joalo-joalo.

Li-MCPCB li sebelisoa sebakeng sa li-PCB tsa setso tsa FR4 kapa CEM3 ka lebaka la bokhoni ba ho qhala mocheso hole le likarolo. Sena se finyelloa ka ho sebelisa Thermally Conductive Dielectric Layer.

Phapang e kholo lipakeng tsa boto ea FR4 le MCPCB ke thepa ea dielectric ea conductivity ea mocheso ho MCPCB. Sena se sebetsa e le borokho bo futhumatsang pakeng tsa likarolo tsa IC le poleiti e tšehetsang tšepe. Mocheso o etsoa ho tloha sephutheloana ka mokokotlo oa tšepe ho ea ho teba e eketsehileng ea mocheso. Ka boto ea FR4 mocheso o lula o tsitsitse haeba o sa fetisetsoe ke heatsink ea topical. Ho latela tlhahlobo ea lab, MCPCB e nang le 1W LED e ile ea lula e le haufi le 25C, ha eona 1W LED botong ea FR4 e fihlile ho 12C ho feta tikoloho. LED PCB e lula e hlahisoa ka Aluminium core, empa ka linako tse ling tšepe ea mantlha ea PCB e boetse e sebelisoa.

Molemo oa MCPCB

1.ho felloa ke mocheso

Li-LED tse ling li senya pakeng tsa 2-5W ea mocheso le ho hlōleha ho etsahala ha mocheso o tsoang ho LED o sa tlosoe hantle; khanya ea khanya ea LED e fokotsehile hammoho le ho senyeha ha mocheso o lula o le teng ka har'a sephutheloana sa LED. Morero oa MCPCB ke ho tlosa mocheso hantle ho tsoa ho li-IC's (eseng feela li-LED). The aluminium base le thermally conductive dielectric layer e sebetsa e le marokho lipakeng tsa IC's le sink ea mocheso. Sekepe se le seng sa mocheso se kentsoeng ka kotloloho setsing sa aluminium se tlosa tlhoko ea lisinki tse ngata tsa mocheso holim'a likarolo tse kentsoeng holim'a metsi.

2. katoloso ea mocheso

Ho atolosoa ha mocheso le ho fokotseha ke tlhaho e tloaelehileng ea ntho, CTE e fapaneng e fapane ka ho atolosoa ha mocheso. E le litšobotsi tsa eona, aluminium le koporo li na le tsoelo-pele e ikhethang ho feta FR4 e tloaelehileng, conductivity ea mocheso e ka ba 0.8 ~ 3.0 W / c.K.

3. botsitso ba dimensional

Ho hlakile hore boholo ba boto ea potoloho e hatisitsoeng ka tšepe e tsitsitse ho feta thepa ea insulating. Phetoho ea boholo ba 2.5 ~ 3.0% ha Aluminium PCB le liphanele tsa sandwich tsa aluminium li ne li futhumatsoa ho tloha 30 ℃ ho ea ho 140 ~ 150 ℃.
