Aluminium base pcb , isu tese tinoziva kuti aluminium isimbi, magetsi conductivity;

Sei rinogona kushandiswa sezvo pcb zvinhu?

Nekuti aruminiyamu substrate inoumbwa nematatu matatu, anoti: mhangura foil, insulation layer uye metallic aluminium.Sezvo paine insulating layer, mukuwedzera kupisa kupisa kuita, iyo yekupisa yekuwedzera coefficient, kupisa kwemagetsi, simba, kuomarara, uremu, mamiriro ezvinhu uye mutengo wesimbi substrate inofanirawo kutariswa.

Pakati pese, tichifunga nezvemutengo uye nehunyanzvi mashandiro, aruminiyamu substrate ndiyo sarudzo yakanaka.Inowanikwa aruminiyamu ndiro 6061,5052,1060, nezvimwewo maCopper substrates anowanikwawo kune epamusoro emagetsi, emagetsi, emagetsi, uye nezvimwe zvakakosha zvivakwa, asi anodhura. .

Inowanzoonekwa pamativi ese ealuminium substrate PCB. Rutivi rumwe chete nemafuta ekuvhara rakasungirirwa nemapini eLED, nepo rimwe divi richiratidza iyo yekutanga ruvara rwealuminium. Kazhinji, iyo yekushisa inoitisa pasita inoiswa uye wozobatana neyakaipisisa inoitisa chikamu.Imwe yemabhenefiti makuru ealuminium substrates pamusoro petsika FR-4 ndeyekuti ivo vanogona kutakura yakakwira ikozvino.Uye nekukurumidza kupisa conduction, kwakanaka kupisa kupisa kuita.

Iyo aruminiyamu substrate inogona kudzora kupisa kupisa kune kushoma, kuitira kuti iyo aluminium substrate ine yakanakisa kupisa conduction mashandiro; Inofananidzwa neceramic substrate, ayo mechimiro zvivakwa ari akaisvonaka.Kuwedzera kune wakanaka kupisa kupisa kuita;

Aluminium substrate zvakare ine zvinotevera zvinotevera:

Mukuenderana neRoHS zvinodzivirira nharaunda, zvinonyanya kukodzera kuita kwe SMT ine yakakwira yazvino simba rekutakura kugadzirisa kupisa kupisa mudunhu dhizaini dhizaini, kuti udzikise tembiricha yekushanda tembiricha, kuwedzera hupenyu hwebasa, nekuvandudza kuwanda kwesimba uye kuvimbika;

Deredza kuungana kwema radiator uye imwe Hardware (inosanganisira yekupisa interface zvinhu), kudzikamisa huwandu hwezvigadzirwa, uye kudzikisira Hardware pamwe nemitengo yegungano; Gonesa musanganiswa wesimba redunhu uye wedunhu rekutonga.

Izvo zviri pamusoro ndezve zvakanakira aruminiyamu substrate, ndinovimba uchaifarira! Tiri pcb fekitari , tinokugamuchira iwe kuti ubvunze zvigadzirwa zvedu zvePCB ~
