Zipinda zotulutsira mpweya za semiconductor zimagwira ntchito ngati zonyamulira zotsekedwa za etching, PVD deposition ndi njira zoyika ma ion, kusankha molakwika kwa alloy kumayambitsa kutulutsa mpweya wambiri, kupotoka kwa kapangidwe kake kapena kutuluka kwa vacuum, zomwe zimachepetsa mwachindunji kupanga kwa wafer. Zonse 5052 H32 ndi 5083 H321 ndi za Al-Mg yosachiritsika kutentha.mitundu ya aluminiyamu yopangidwa ndi zinthu zopangidwa,komabe mitundu yosiyanasiyana ya magnesium ndi manganese imagawaniza kwambiri zochitika zawo zogwirira ntchito za semiconductor cavity.

Chemistry imayika malire a magwiridwe antchito. 5052 ili ndi 2.2~2.8 wt% Mg yokhala ndi gawo la Mn lochepera 0.1%, pomwe 5083 imakweza kuchuluka kwa Mg kufika pa 4.0~4.9% kuphatikiza 0.4~1.0% manganese kuti ikonzedwe bwino komanso kuti ilimbikitse yankho lolimba. Kusiyana kumeneku kumapereka mphamvu yolimba yokwanira ndi 38~42% pa 5083 (310~320MPa vs 215~230MPa ya 5052), zomwe zimapangitsa kuti ikhale njira yawo yoyamba yopangira nyumba za semiconductor.

5052 imayang'anira zipinda zosinthira zazing'ono, zovuta komanso zotsekera katundu m'zida za semiconductor zapakatikati. Kupangika kwake kozizira kwambiri komanso kusinthasintha kwake kumapangitsa kuti machining a CNC azitha kupangidwa mozama kwambiri, kupukusa njira yozizira modabwitsa komanso kupanga ma flange ochepa popanda kusintha kwa springback. Chitsulochi chimakhala ndi mphamvu yotsika yotulutsa mpweya pansi pa 10⁻⁸ Torr·L/(s·cm²) pambuyo popukuta bwino, kufananiza miyezo yoyambira ya vacuum (UHV) ya batch type small volume process cavities. Kugwiritsa ntchito bwino ndalama ndi chinthu china chofunikira: kugwiritsa ntchito zinthu zopangira 5052 cuts 12~15% poyerekeza ndi 5083, yoyenera kwambiri ma OEM mass semiconductor peripheral casings ndi ma assivity sensor mounting cavities. Fakitale yathu imapeza blanking ya voliyumu yambiri komansokumaliza kukonza mapepala a 5052, mipiringidzo yolimba ndi machubu a aluminiyamu osapindika okhala ndi ±0.003mm kulekerera kwa miyeso kudzera m'malo opangira machining a CNC okhala ndi axis zisanu.

Kusunthira ku zipinda zazikulu zogwirira ntchito zolemera, ndipo 5083 imakhala yosasinthika. Kulimba kwake kwakukulu kwa makina kumalimbana ndi kusintha kwa kupanikizika kwa vacuum cyclic differential pressure ndi kukwera mobwerezabwereza kwa kutentha pansi pa kutentha kochepa mkati mwa maenje oyikamo. H321 tempered 5083 ili ndi kukana kwa optimized stress corrosion cracking (SCC) motsutsana ndi mpweya wowononga wa halogen, wofunikira kwambiri pazida zapamwamba zogwiritsidwa ntchito ndi mpweya wokhala ndi fluorine. Kulimba kwapamwamba kwa cryogenic kumakwaniranso zipinda zogwirira ntchito za semiconductor zotentha kwambiri zomwe zikuyenda pamalo ogwirira ntchito a sub zero, kupewa kulephera kwa brittle crack pansi pa kutentha.

Mphamvu yathu yopangira mkati imathandizira makina opangidwa mwamakonda a alloys onse awiri. Tili ndi malo ochitira masewera olimbitsa thupi a Class 10,000, chowunikira kutayikira kwa helium mass spectrometer ndi mzere woyeretsera wa ultrasonic wodzipangira okha, timakwaniritsa ntchito imodzi kuyambira kudula aluminiyamu, kukonza CNC molondola, kulumikiza mpweya wa inert-gas TIG mpaka kumaliza bwino kwambiri pazinthu za semiconductor cavity. Kutulutsa kwa mwezi uliwonse kumafika matani opitilira 35 a zida zomalizidwa za 5052/5083, zomwe zimaphatikizapo mbale ya aluminiyamu yopangidwa mwamakonda, bala yolimba ya aluminiyamu ndi chubu cha aluminiyamu chopanda kanthu chomwe chimaperekedwa pamodzi ndi kapangidwe ka chipinda chomalizidwa.

Kwa makasitomala omwe asokonezeka ndi kusankha magiredi:sankhani 5052 kuti ikhale yopepuka, mabowo ang'onoang'ono ovuta omwe amakhudzidwa ndi mtengo. Sankhani 5083 kuti mupeze zipinda zazikulu, zolemera kwambiri, komanso zowononga zachilengedwe. Gulu lathu la mainjiniya limapereka upangiri waulere wa FEA woyeserera kapangidwe kake komanso kusankha zinthu kuti muwongolere bajeti yanu yogulira semiconductor enclosure komanso kukhazikika kwa zida kwa nthawi yayitali.
