Aluminium base pcb , kaofela rea ​​tseba hore aluminium ke tšepe, motlakase o tsamaisang motlakase;

E ka sebelisoa e le lintho tse bonahalang tsa PCB joang?

Hobane aluminium substrate e entsoe ka mekhahlelo e meraro, e leng: koporo ea koporo, lera la ho koala le aluminium ea tšepe. le litšenyehelo tsa substrate ea tšepe le tsona li lokela ho tsotelloa.

Ka kakaretso, ha ho shejoa litšenyehelo le ts'ebetso ea mahlale, aluminium substrate ke khetho e ntle.Lipoleiti tsa aluminium tse fumanehang 6061,5052,1060, jj. Lisebelisoa tsa koporo le tsona lia fumaneha bakeng sa thepa e phahameng ea mocheso, mochini, motlakase le thepa e ngoe e khethehileng, empa e theko e phahameng haholo. .

E atisa ho bonoa ka mahlakore ka bobeli a aluminium substrate PCB. Lehlakore le leng le nang le oli ea sekoaelo le entsoe ka lithakhisa tsa LED, ha lehlakore le leng le bontša 'mala oa pele oa aluminium. Ka kakaretso, pente e futhumatsang e tla sebelisoa ebe o ikopanya le karolo e futhumatsang e 'ngoe ea melemo e meholohali ea likaroloana tsa aluminium ho feta moetlo oa FR-4 ke hore li ka tsamaisa mokelikeli o phahameng haholo oa hona joale.

Sesebelisoa sa aluminium se ka fokotsa mocheso oa mocheso ho isa bonyane, e le hore substrate ea aluminium e na le ts'ebetso e ntle ea ho tsamaisa mocheso; Ha e bapisoa le substrate ea ceramic, thepa ea eona ea mochini e metle haholo, ntle le ts'ebetso e ntle ea ho chesa mocheso;

Aluminium substrate le eona e na le melemo e latelang:

Tumellanong le litlhoko tsa ts'ireletso ea tikoloho ea RoHS, e loketse ts'ebetso ea SMT e nang le matla a holimo a hona joale a ho sebetsana le ho hasana ha mocheso morerong oa moralo oa potoloho, e le ho fokotsa mocheso oa mochini o sebetsang, ho eketsa bophelo ba ts'ebeletso, le ho ntlafatsa boleng ba matla le ts'epahalo;

Fokotsa kopano ea li-radiator le lisebelisoa tse ling (ho kenyeletsoa thepa ea sehokelo sa mocheso), fokotsa molumo oa lihlahisoa, le ho fokotsa litšenyehelo tsa hardware le kopano; Lokisetsa ho kopanya ha potoloho ea motlakase le taolo ea potoloho.

Tse boletsoeng kaholimo li mabapi le melemo ea substrate ea aluminium, ke ts'epa hore o tla e rata! Re PCB fektheri , rea u amohela ho sheba lihlahisoa tsa rona tsa PCB ~
