Aluminium substrate e le mofuta o khethehileng oa PCB, tšimo ea eona ea kopo e 'nile ea e-ba nako e telele ho pholletsa le puisano, matla, matla, mabone a LED le liindasteri tse ling, haholo-holo lisebelisoa tsa elektronike tse matla haholo li tla batla li sebelisa substrate ea aluminium, le substrate ea aluminium e tumme haholo. ka lebaka la litšobotsi tse latelang:

Ts'ebetso e ntle ea ho felisa mocheso: Joalo ka ha bohle re tseba, phepelo ea mocheso e bohlokoa haholo bakeng sa lisebelisoa tsa elektroniki tse nang le matla a phahameng, 'me tšobotsi e kholo ka ho fetisisa ea aluminium substrate ke ts'ebetso ea eona e ntle ea ho felisa mocheso, ha e bapisoa le litšepe tse ling le lialloys, aluminium e na le conductivity e phahameng ea mocheso. matla a tlaase a mocheso, a etsang hore substrate ea aluminium e khone ho tsamaisa le ho qhala mocheso o hlahisoang ke likarolo tsa elektronike ka katleho. Ka hona ho ntlafatsa ho tšepahala, botsitso le bophelo ba tšebeletso ea lisebelisoa.

Matla a machane: aluminium e batla e le bonolo ha e bapisoa le lisebelisoa tse ling tsa tšepe, kahoo polasetiki ea eona e matla, 'me e ka sebetsoa ka libopeho tse fapaneng, e le ho sebetsa litlhoko tse fapaneng tsa moralo oa PCB.

Ho hanyetsa kutu e ntle haholo: Aluminium e pepesehetse sepakapaka, ho bonolo ho etsa filimi ea oxide holim'a metsi, lera lena la oxide filimi e ka fana ka tšireletso e itseng bakeng sa substrate ea aluminium, kahoo substrate ea aluminium ka boeona e na le khanyetso e itseng ea kutu, ehlile, karolo ena ea filimi ea oxide ka lebaka la tikoloho e phahameng ea alkaline kapa acidic e lekane haholo, ka hona, molemong oa ho ntlafatsa ho hanyetsa kutu ea aluminium substrate, ts'ebetsong ea tlhahiso, mekhoa e meng ea kalafo ea holim'a metsi e atisa ho nkoa ho fana ka ts'ebetso ea ho hanyetsa kutu. aluminium substrate, le substrate ea aluminium ka mor'a phekolo ea holim'a metsi e ka sebetsa ka mokhoa o tsitsitseng libakeng tse ling tse khethehileng.
