Aluminium substrate yog ib hom tshwj xeeb ntawm PCB, nws daim ntawv thov teb tau ntev lawm thoob plaws kev sib txuas lus, lub zog, lub zog, LED teeb pom kev zoo thiab lwm yam lag luam, tshwj xeeb tshaj yog cov khoom siv hluav taws xob muaj zog yuav luag siv aluminium substrate, thiab aluminium substrate yog li nrov, yog vim nws cov yam ntxwv hauv qab no:

Kev ua tau zoo ntawm cov cua kub dissipation: Raws li peb txhua tus paub, qhov kub dissipation yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob muaj zog, thiab qhov loj tshaj plaws ntawm aluminium substrate yog nws cov thermal dissipation kev ua tau zoo, piv nrog rau lwm cov hlau thiab alloys, txhuas muaj thermal conductivity ntau dua. qis dua lub peev xwm, uas ua rau aluminium substrate tuaj yeem ua tau zoo dua thiab cuam tshuam cov cua sov uas tsim los ntawm cov khoom siv hluav taws xob. Yog li txhim kho kev ntseeg siab, ruaj khov thiab kev pabcuam lub neej ntawm cov khoom siv.

Muaj zog machinability: aluminium yog qhov muag muag piv nrog lwm cov ntaub ntawv hlau, yog li nws cov yas muaj zog, thiab nws tuaj yeem ua tiav rau hauv ntau yam duab, thiaj li siv tau rau ntau yam sib txawv PCB tsim xav tau.

Kev tiv thaiv corrosion zoo heev: Aluminium raug rau huab cua, nws yog ib qho yooj yim los tsim cov oxide zaj duab xis rau saum npoo, txheej txheej ntawm oxide zaj duab xis tuaj yeem muab qee qhov kev tiv thaiv rau txhuas substrate, yog li txhuas substrate nws tus kheej muaj qee yam corrosion kuj, ntawm chav kawm, txheej txheej ntawm oxide zaj duab xis nyob rau hauv cov lus teb rau siab alkaline los yog acidic ib puag ncig txaus txaus, yog li, txhawm rau txhim kho corrosion kuj ntawm aluminium substrate, nyob rau hauv cov txheej txheem ntau lawm, qee qhov txheej txheem kho deg feem ntau yog coj los ntxiv rau kev tiv thaiv corrosion ntawm aluminium substrate, thiab aluminium substrate tom qab kho deg tuaj yeem ua haujlwm ruaj khov hauv qee qhov chaw tshwj xeeb.
