Iyo yepakati nepamusoro yemuviri aluminium silicon carbide inoumbwa zvinhu zvatakatora pamhando nyowani yekugadzira gadziriro isina chiratidziro chikamu, iyo inodzivirira zvinobudirira kukanganisa kweiyo brittleness yesimbi ceramic composite zvinhu, uye inovandudza zvakanyanya mashandiro uye mashandisirwo emhando yezvigadzirwa.
1. Aluminium silicon carbide - zvimiro zvikamu
Yakakwirira-yakasimba yakanyatso kurongeka zvikamu - zvine hunhu hwehuremu, kuomarara kwepamusoro, kugadzikana kwedimensional, kupfeka kuramba uye kusagadzikana kwemarara, pachinzvimbo chealuminium alloy, simbi isina tsvina, titanium alloy, inoshandiswa mukurongeka kwepamusoro-soro, kusapfeka-inodzivirira mativi ane huremu zvinodiwa. .

Zvibereko zvechigadzirwa: High thermal conductivity, surface function diversified design, Low thermal expansion coefficient (yakafanana neiyo thermal yekuwedzera coefficient ye chip material) Low welding porosity.
IGBT package base plate: Thermal conductivity yealuminium silicon carbide yakakwira uye yakaderera kupisa kwekuwedzera kweyekupisa coefficient (mafuta ekuwedzera coefficient akafanana neiyo chip zvinhu), zvinonyatso dzikisa mukana wepakeji kutsemuka, kunatsiridza hupenyu hwesevhisi yechigadzirwa. Muchitima chinomhanya-mhanya, mota nyowani dzesimba, radar, kugadzirwa kwesimba remhepo kutsiva aluminium, mhangura, tungsten yemhangura, mhangura molybdenum, beryllium, ceramics uye mamwe mamicroelectronic ekurongedza zvinhu.
