Melemo ea substrate ea aluminium PCB

a. Ho senya mocheso ho molemo haholo ho feta mokhoa o tloaelehileng oa FR-4.

b. Dielectric e sebelisoang hangata ke makhetlo a 5 ho isa ho a 10 ho feta mocheso oa mocheso oa khalase ea epoxy ea setso le 1/10 ea botenya.

c. Lenane la ho fetisa mocheso le sebetsa ho feta PCB e thata ea setso.

d. U ka sebelisa boima ba koporo bo tlase ho feta bo bontšitsoeng chate e khothaletsoang ke IPC.

Aluminium PCB

Tšebeliso ea aluminium substrate PCB

1. Lisebelisoa tsa molumo: li-amplifiers tse kenyang le tse hlahisoang, li-amplifiers tse leka-lekaneng, li-audio amplifiers, preamplifiers, amplifiers matla, joalo-joalo.

2. Lisebelisoa tsa ho fana ka matla: regulator ea ho fetola, DC / AC converter, SW regulator, joalo-joalo.

3. Lisebelisoa tsa elektronike tsa puisano: amplifier e phahameng-frequency tlaleho ea potoloho.

4. Thepa ea othomathike ea ofisi: li-motor drive, joalo-joalo.

5. Koloi: molaoli oa elektronike, motlakase, molaoli oa matla, joalo-joalo.

6. Khomphuta: CPU board `floppy disk drive’ yuniti ea phepelo ea matla, joalo-joalo.

7. Module oa matla: inverter “solid state relay” rectifier borokho, joalo-joalo.

Li-substrates tsa aluminium li sebelisoa haholo. Ka kakaretso lisebelisoa tsa molumo, lisebelisoa tsa motlakase, le lisebelisoa tsa elektronike tsa puisano, ho na le li-PCB tsa aluminium substrate, lisebelisoa tsa ofisi, likoloi, lik’homphieutha le li-module tsa matla.

Ho na le liphapano tse tharo lipakeng tsa boto ea fiberglass le aluminium substrate PCB

A. Theko

Likarolo tsa bohlokoa tsa tube ea fluorescent ea LED ke: boto ea potoloho, chip ea LED le phepelo ea matla a ho khanna. Mapolanka a tloaelehileng a potoloho a arotsoe ka mefuta e ‘meli: substrates ea aluminium le mapolanka a fiberglass. Ha ho bapisoa theko ea boto ea fiberglass le substrate ea aluminium, theko ea boto ea fiberglass e tla ba theko e tlase haholo, empa ts’ebetso ea substrate ea aluminium e tla ba betere ho feta ea boto ea fiberglass.

B. Likarolo tsa tekheniki

Ho ea ka lisebelisoa tse fapaneng le lits’ebetso tsa tlhahiso, liboto tsa fiberglass li ka aroloa ka mefuta e meraro: liboto tsa fiberglass tse mahlakoreng a mabeli, liboto tsa fiberglass tse nang le mahlakore a le mong, le mapolanka a fiberglass a nang le lehlakore le le leng. Ha e le hantle, theko ea mapolanka a fiberglass a entsoeng ka thepa e fapaneng e tla fapana. Litheko tsa liphanele tsa fiberglass tse entsoeng ka thepa le mahlale a fapaneng le tsona li fapane. Phello ea ho senya mocheso ea LED fluorescent tube le glass fiber board ha e ntle joaloka ea LED fluorescent tube e nang le substrate ea aluminium.

C. Tshebetso

Joalo ka ha bohle re tseba, substrate ea aluminium e na le ts’ebetso e ntle ea ho felisa mocheso, ‘me ts’ebetso ea eona ea ho senya mocheso e betere ho feta boto ea fiberglass. Hobane substrate ea aluminium e na le conductivity e ntle ea mocheso, substrate ea aluminium e phetha karolo ea bohlokoa tšimong ea mabone a LED.
