Aluminium substrate semhando yakakosha yePCB, munda wayo wekushandisa wakagara kwenguva yakareba pamusoro pekutaurirana, simba, simba, mwenje we LED uye mamwe maindasitiri, kunyanya magetsi emagetsi emagetsi anoshandisa aluminium substrate, uye aluminium substrate yakakurumbira, nekuda kwezvimiro zvayo zvinotevera:

Yakanakisa kupisa kupisa kuita: Sezvatinoziva tese, kupisa kupisa kunonyanya kukosha kune yakakwirira-simba midziyo yemagetsi, uye chinhu chikuru chealuminium substrate kuita kwayo kwakanakisa kupisa kupisa, zvichienzaniswa nedzimwe simbi uye alloys, aruminiyamu ine yakakwirira yekupisa conductivity uye. yakaderera kupisa simba, iyo inoita aluminium substrate inogona kunyatsoita uye kuparadzira kupisa kunoitwa nemagetsi zvikamu. Nokudaro kuvandudza kuvimbika, kugadzikana uye hupenyu hwebasa remidziyo.

Yakasimba machinability: aruminiyamu yakapfava kana ichienzaniswa nezvimwe zvinhu zvesimbi, saka plastiki yayo yakasimba, uye inogona kugadzirwa kuita akasiyana maumbirwo, kuitira kuti ishandiswe kune akasiyana siyana PCB dhizaini zvinodiwa.

Yakanakisa corrosion resistance: Aluminium yakazarurwa kumhepo, zviri nyore kuumba oxide firimu pamusoro, iyi layer ye oxide film inogona kupa imwe dziviriro yealuminium substrate, saka iyo aluminium substrate pachayo ine imwe corrosion resistance, hongu, iyi layer ye oxide firimu mukupindura kune yakakwira alkaline kana acidic nharaunda yakawandisa, saka, kuitira kukwidziridza corrosion kuramba kwealuminium substrate, mukugadzira maitiro, mamwe maitiro ekurapa epamusoro anowanzo kutorwa kuti aenderere mberi nekupa iyo corrosion resistance. iyo aluminium substrate, uye iyo aluminium substrate mushure mekurapwa kwepamusoro inogona kushanda zvakatsiga mune dzimwe nzvimbo dzakakosha.
