Cov ntaub ntawv tseem ceeb ntawm aluminium-raws li cov ntawv luam tawm Circuit Board (PCB) muaj peb txheej txheej txheej: txheej txheej (tooj liab ntawv), txheej thermal rwb thaiv tsev, thiab txheej hlau puag txheej (txhuas phaj).
Aluminium Base: Ua hauj lwm raws li cov khoom siv hauv paus rau lub substrate, aluminium muaj cov thermal conductivity zoo heev, ua rau kev hloov pauv sai ntawm cov cua sov. Qhov no ua kom ntseeg tau tias cov cua sov uas tsim los ntawm cov khoom siv hluav taws xob yog dissipated tam sim ntawd, yog li tswj xyuas qhov kub thiab txias.
Rwb thaiv tsev txheej: Feem ntau yog tsim los ntawm cov ntaub ntawv insulating-xws li ceramics- txheej txheej no zoo cais cov seem sib txawv ntawm lub voj voog. Nws tiv thaiv luv luv Circuit Court, tiv thaiv kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm ntawm circuitry, thiab ib txhij txhim kho cov hluav taws xob rwb thaiv tsev ntawm aluminium substrate.
Txheej Txheej: Feem ntau yog ua los ntawm tooj liab, txheej txheej no ua rau tooj liab qhov tshwj xeeb hluav taws xob conductivity nqa tam sim no thiab pab txhawb kev xa xov hluav taws xob. Tsis tas li ntawd, tooj liab qhov zoo tshaj plaws ductility tso cai rau kev sib txuas lus ncaj qha, yog li ua tau raws li qhov yuav tsum tau ua ntawm cov qauv tsim hluav taws xob.
Los ntawm kev sib koom ua ke ntawm cov ntaub ntawv no, aluminium substrate xa cov kev ua tau zoo ntawm cov cua kub dissipation thiab cov yam ntxwv hluav taws xob. Nws yog dav siv thoob plaws ntau yam khoom siv hluav taws xob, muab kev txhawb nqa ruaj khov thiab txhim khu kev qha rau cov khoom siv hluav taws xob thiab pab txhawb kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob.
