Alumina Ceramic Gawo la Zamagetsi Zamagetsi
Munda Wofunsira
Zigawo za aluminiyamu za ceramic zomwe zimagwiritsidwa ntchito kwambiri pazigawo zamagetsi zomwe zimakhala ndi makina apamwamba kwambiri, kuuma kwakukulu, kuvala kwautali, kukana kwakukulu kwa kutchinjiriza, kuteteza dzimbiri bwino, kutentha kwambiri kugonjetsedwa.
Alumina ceramic capacitors:Zoumba za aluminiyamu zili ndi zinthu zabwino za dielectric ndipo zimatha kugwiritsidwa ntchito kupanga ma capacitor a ceramic.Ma capacitor awa amakhala okhazikika bwino ndipo amatha kugwira ntchito m'malo ovuta monga kutentha kwambiri, kuthamanga kwambiri, komanso chinyezi chambiri, zomwe zimapangitsa kuti azigwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi.
Alumina ceramic ma CD zida:Zoumba za aluminiyamu zimakhala ndi kukana kutentha kwabwino, kukana kwa dzimbiri, komanso kukana kuvala, ndipo zimagwiritsidwa ntchito kwambiri muzonyamula za semiconductor.Amatha kuteteza tchipisi ta semiconductor kuti asasokonezedwe ndi chilengedwe chakunja ndi kuwonongeka, ndikuwongolera kukhazikika ndi kudalirika kwa zida za semiconductor.
Mwachidule, mbali za alumina ceramics zimakhala ndi ntchito zosiyanasiyana pazigawo zamagetsi ndipo zimagwira ntchito yofunika.Ndi chitukuko chosalekeza chaukadaulo, kugwiritsa ntchito alumina ceramics muzinthu zamagetsi kupitilira kukula ndikuzama.
Tsatanetsatane
Chofunikira pa kuchuluka:1pc mpaka 1 miliyoni pcs.Palibe MQQ yochepa.
Sample nthawi yotsogolera:kupanga zida ndi 15days+ kupanga 15days.
Nthawi yopanga:Masiku 15 mpaka 45.
Nthawi yolipira:kukambilana ndi mbali zonse.
Njira yopangira:
Alumina(AL2O3) ceramic ndi ceramic ya mafakitale yomwe imakhala ndi kuuma kwambiri, kuvala kwautali, ndipo imatha kupangidwa ndi kugaya diamondi.Amapangidwa kuchokera ku bauxite ndipo amamalizidwa ndi jekeseni, kukanikiza, sintering, kugaya, sintering ndi machining process.

Kulongedza
Nthawi zambiri timagwiritsa ntchito zinthu zomwe sizingawonongeke, zomwe sizingawonongeke.Timagwiritsa ntchito chikwama cha PP ndi mapaleti amatabwa katoni malinga ndi zomwe kasitomala amafuna.Zoyenera kuyenda panyanja ndi ndege.
