Aluminium PCB - PCB e bonolo ea ho senya mocheso

Karolo ea Pele: Aluminium PCB ke eng?

Aluminium substrate ke mofuta oa boto e entsoeng ka koporo e entsoeng ka tšepe e nang le ts'ebetso e ntle ea ho senya mocheso.Ka kakaretso, boto e nang le lehlakore le le leng e entsoe ka likarolo tse tharo: lera la potoloho (foil ea koporo), lesela le sireletsang, le lera la motheo la tšepe.Bakeng sa lits'ebetso tse phahameng, ho boetse ho na le meralo e nang le mahlakore a mabeli e nang le sebopeho sa lera la potoloho, lera la insulating, setsi sa aluminium, lesela la insulating, le lesela la potoloho.Palo e nyane ea lits'ebetso e kenyelletsa mapolanka a marang-rang a mangata, a ka bopiloeng ka ho kopanya mapolanka a tloaelehileng a marang-rang a nang le likarolo tse sireletsang le metheo ea aluminium.

Aluminium substrate e nang le lehlakore le le leng: E ​​na le lera le le leng la mokhoa oa conductive, thepa e sireletsang, le poleiti ea aluminium (substrate).

Aluminium substrate e nang le mahlakore a mabeli: E kenyelletsa likarolo tse peli tsa likarolo tsa conductive, thepa e sireletsang, le poleiti ea aluminium (substrate) e kopantsoeng hammoho.

Multi-lara hatisitsoeng aluminium potoloho boto: Ke e hatisitsoeng oa potoloho boto entsoeng ka laminating le bonding tse tharo kapa ho feta magato a conductive paterone lera, insulating lintho tse bonahalang, le poleiti aluminium (substrate) hammoho.

E arotsoe ka mekhoa ea phekolo ea holim'a metsi:
Boto e kentsoeng ka khauta (Khauta e tšesaane ea k'hemik'hale, Khauta e teteaneng ea lik'hemik'hale, Ho rala khauta e khethiloeng)

 

Karolo ea Bobeli: Molao-motheo o sebetsang oa Aluminium Substrate

Lisebelisoa tsa matla li behiloe holim'a lera la potoloho.Mocheso o hlahisoang ke lisebelisoa nakong ea ts'ebetso o etsoa ka potlako ka lera la insulating ho ea tšepe ea motheo ea tšepe, e ntan'o senya mocheso, ho finyella mocheso oa mocheso bakeng sa lisebelisoa.

Ha ho bapisoa le setso sa FR-4, likaroloana tsa aluminium li ka fokotsa khanyetso ea mocheso, tsa li etsa li-conductors tse ntle haholo tsa mocheso.Ha li bapisoa le li-circuits tsa ceramic tse nang le lifilimi tse teteaneng, li boetse li na le thepa e phahameng ea mochini.

Ho feta moo, li-substrates tsa aluminium li na le melemo e latelang e ikhethang:
- Ho ikamahanya le ditlhoko tsa RoHs
- Ho ikamahanya le maemo ho betere lits'ebetsong tsa SMT
- Ho sebetsana ka katleho le phallo ea mocheso moralong oa potoloho ho fokotsa mocheso oa mochini o sebetsang, ho lelefatsa nako ea bophelo, ho matlafatsa letsoalo la matla le ts'epahalo.
- Phokotso ea ho bokelloa ha lisinki tsa mocheso le lisebelisoa tse ling, ho kenyelletsa le lisebelisoa tsa sehokelo sa mocheso, ho fella ka bongata bo fokolang ba sehlahisoa le litšenyehelo tse tlase tsa lisebelisoa le kopano, le motsoako o nepahetseng oa matla le li-circuits tsa taolo.
- Phetoho ea li-substrates tse senyehang tsa ceramic bakeng sa ts'ebetso e ntlafalitsoeng ea mochini

Karolo ea Boraro: Sebopeho sa Aluminium Substrates
1. Lera la Potoloho
Lera la potoloho (hangata le sebelisa foil ea koporo ea electrolytic) e hlophisoa ho etsa lipotoloho tse hatisitsoeng, tse sebelisetsoang kopano ea likarolo le likhokahano.Ha ho bapisoa le setso sa FR-4, se nang le botenya bo tšoanang le bophara ba mela, li-substrates tsa aluminium li ka tsamaisa maqhubu a phahameng.

2. Insulating Layer
The insulating layer ke theknoloji ea bohlokoa ho li-substrates tsa aluminium, tse sebeletsang haholo bakeng sa ho khomarela, ho kenya letsoho le ho tsamaisa mocheso.Lera le sireletsang la li-substrates tsa aluminium ke mokoallo oa bohlokoa ka ho fetisisa oa mocheso meahong ea module ea matla.Molemo o motle oa ho futhumatsa mocheso oa lera la insulating o thusa ho ata ha mocheso o hlahisoang nakong ea ts'ebetso ea sesebelisoa, e lebisang ho thecheso e tlase ea ts'ebetso, ho eketseha ha matla a mojule, boholo bo fokotsehileng, nako e telele ea bophelo, le tlhahiso e phahameng ea matla.

3. Metal Base Layer
Khetho ea tšepe bakeng sa motheo oa tšepe e sireletsang e itšetlehile ka lintlha tse pharaletseng tsa lintlha tse kang coefficient ea motheo ea tšepe ea ho atolosa mocheso, conductivity ea mocheso, matla, boima, boima, boemo ba holim'a metsi le litšenyehelo.

Karolo ea bone: Mabaka a ho Khetha Aluminium Substrates
1. Ho Felisoa ha Mocheso
Liboto tse ngata tse mahlakoreng a mabeli le tse ngata li na le sekhahla se phahameng le matla, e leng se etsang hore ho qhala mocheso ho be thata.Lisebelisoa tse tloaelehileng tsa substrate tse kang FR4 le CEM3 ke li-conductors tse futsanehileng tsa mocheso 'me li na le li-inter-layer insulation, tse lebisang ho se nang mocheso o lekaneng oa mocheso.Li-substrates tsa aluminium li rarolla bothata bona ba ho felisa mocheso.

2. Ho Atolosoa ha Mocheso
Katoloso ea mocheso le ho honyela li amana le thepa, 'me lintho tse fapaneng li na le li-coefficients tse fapaneng tsa katoloso ea mocheso.Liboto tse hatisitsoeng tse thehiloeng ka aluminium li sebetsana ka katleho le litaba tsa ho felloa ke mocheso, ho nolofatsa bothata ba ho atolosoa ha mocheso o fapaneng ka likarolo tsa boto, ho ntlafatsa ho tšoarella ka kakaretso le ho tšepahala, haholo-holo lits'ebetsong tsa SMT (Surface Mount Technology).

3. Botsitso ba Dimensional
Liboto tse hatisitsoeng tse thehiloeng ka aluminium li tsitsitse haholo ho latela boholo ha li bapisoa le liboto tse hatisitsoeng tsa insulated.Phetoho ea boholo ba liboto tse hatisitsoeng tse thehiloeng aluminium kapa liboto tsa mantlha tsa aluminium, tse futhumetseng ho tloha ho 30 ° C ho isa ho 140-150 ° C, ke 2.5-3.0%.

4. Mabaka a Mang
Mapolanka a hatisitsoeng a aluminium a na le liphello tse sireletsang, a nkela sebaka sa brittle ceramic substrates, a loketse bakeng sa theknoloji ea ho kenya holim'a metsi, a fokotsa sebaka se sebetsang sa mapolanka a hatisitsoeng, a nkela likarolo tse kang licheso tsa mocheso ho matlafatsa ho hanyetsa mocheso oa sehlahisoa le thepa ea 'mele, le ho fokotsa litšenyehelo tsa tlhahiso le mosebetsi.
