Ndi kuipa kotani kwa granite pamsika wa semiconductor?

Pansi pa zofunikira zolimba kwambiri komanso kudalirika kwakukulu mumakampani a semiconductor, ngakhale granite ndi imodzi mwazinthu zazikulu, katundu wake amabweretsanso zofooka zina. Zotsatirazi ndizovuta zake zazikulu ndi zovuta pazogwiritsa ntchito:
Choyamba, zinthuzo ndizovuta kwambiri komanso zovuta kuzikonza
Chiwopsezo chosweka: Granite kwenikweni ndi mwala wachilengedwe wokhala ndi ming'alu yaying'ono yachilengedwe ndi malire a tinthu tating'ono mkati mwake, ndipo ndi zinthu zomwe zimawonongeka. M'makina olondola kwambiri (monga kugaya nanoscale ndi zovuta zokhotakhota pamwamba), ngati mphamvuyo ili yosagwirizana kapena magawo opangirawo ndi osayenera, mavuto monga kupukuta ndi kufalitsa kwa microcrack nthawi zambiri kumachitika, zomwe zimapangitsa kuti chogwirira ntchito chichotsedwe.

Kuchita bwino kwambiri: Kuti mupewe kuwonongeka kwa brittle, njira zapadera monga kugaya pang'ono ndi mawilo a diamondi ndi kupukuta kwa magnetorheological ndizofunikira. The processing mkombero ndi 30% mpaka 50% yaitali kuposa zipangizo zitsulo, ndi zida ndalama ndalama ndi mkulu (mwachitsanzo, mtengo wa asanu olamulira kugwirizana Machining Center kuposa yuan miliyoni 10).
Zolepheretsa kamangidwe kake: Ndizovuta kupanga zomangira zopepuka zopanda pake kudzera muzojambula, zopanga ndi zina. Amagwiritsidwa ntchito kwambiri m'mawonekedwe osavuta a geometric monga mbale ndi maziko, ndipo kugwiritsa ntchito kwake kumakhala kochepa pazida zomwe zimafuna zothandizira mosagwirizana kapena kuphatikiza mapaipi amkati.
Chachiwiri, kuchulukitsitsa kwakukulu kumabweretsa katundu wolemera pazida
Zovuta kuzigwira ndikuyika: Kuchulukana kwa granite ndi pafupifupi 2.6-3.0 g/cm³, ndipo kulemera kwake ndi 1.5-2 kuwirikiza chitsulo choponyedwa pansi pa voliyumu yomweyo. Mwachitsanzo, kulemera kwa maziko a granite pamakina ojambula zithunzi kumatha kufika matani 5 mpaka 10, zomwe zimafunikira zida zonyamulira zodzipatulira ndi maziko osagwedezeka, zomwe zimawonjezera mtengo womanga fakitale ndi kutumiza zida.
Dynamic response lag: High inertia imachepetsa kuthamanga kwa zida zosuntha (monga ma loboti osintha mawafa). Muzochitika zomwe kuyambika ndi kuyimitsidwa mwachangu kumafunikira (monga zida zoyendera mwachangu), zitha kukhudza kamvekedwe kazinthu ndikuchepetsa mphamvu.
Chachitatu, mtengo wokonza ndi kubwereza ndi wokwera
Zowonongeka zimakhala zovuta kukonza: Ngati kuwonongeka kwa pamwamba kapena kugundana kumachitika pakagwiritsidwa ntchito, kumayenera kubwezeredwa kufakitale kuti kukonzeredwe pogwiritsa ntchito zida zogaya zaukatswiri, zomwe sizingachitidwe mwachangu pamalopo. Mosiyana ndi izi, zigawo zachitsulo zimatha kukonzedwa nthawi yomweyo kudzera mu njira monga kuwotcherera malo ndi laser cladding, zomwe zimapangitsa kuti nthawi yocheperako ikhale yochepa.
Mapangidwe obwerezabwereza ndi aatali: Kusiyana kwa mitsempha yachilengedwe ya granite kungayambitse kusinthasintha pang'ono kwa zinthu zakuthupi (monga kuchuluka kwa matenthedwe ndi chiŵerengero cha kutentha) kwa magulu osiyanasiyana. Ngati kamangidwe ka zida kasintha, zinthuzo ziyenera kufananizidwanso, ndipo nthawi yotsimikizira kafukufuku ndi chitukuko ndi yayitali.
Iv. Zida Zochepa ndi Zovuta Zachilengedwe
Mwala wachilengedwe ndi wosasinthika: granite yapamwamba kwambiri (monga "Jinan Green" ndi "Sesame Black" yomwe imagwiritsidwa ntchito mu semiconductors) imadalira mitsempha yeniyeni, ili ndi nkhokwe zochepa ndipo migodi yake imaletsedwa ndi ndondomeko zoteteza chilengedwe. Ndi kukula kwa mafakitale a semiconductor, pakhoza kukhala chiwopsezo cha kusakhazikika kwazinthu zopangira.
Kukonza nkhani za kuipitsa: Panthawi yodula ndi kupera, fumbi la granite (lomwe lili ndi silicon dioxide) limapangidwa. Ngati sichisamalidwa bwino, chingayambitse siliconosis. Kuphatikiza apo, madzi otayira amafunika kuthandizidwa ndi sedimentation asanatulutsidwe, ndikuwonjezera ndalama zoteteza chilengedwe.
Asanu. Kusagwirizana kokwanira ndi njira zomwe zikubwera
Zolepheretsa chilengedwe cha vacuum: Njira zina za semiconductor (monga zokutira vacuum ndi electron beam lithography) zimafuna kukhala ndi mpweya wambiri mkati mwa zipangizo. Komabe, ma micro-pores pamwamba pa granite amatha kukopa mamolekyu a gasi, omwe amamasulidwa pang'onopang'ono ndikusokoneza kukhazikika kwa digiri ya vacuum. Chifukwa chake, chithandizo chowonjezera cha kachulukidwe chapamwamba (monga utomoni impregnation) ndichofunika.
Mavuto okhudzana ndi ma elekitiroleti: Granite ndi zinthu zoteteza. Muzochitika zomwe zimafunikira kutulutsa magetsi osasunthika kapena kutchingira kwamagetsi (monga mapulatifomu otchinga ma electrostatic adsorption), zokutira zachitsulo kapena makanema oyendetsa amafunika kuphatikizidwa, kukulitsa kuchulukira kwamapangidwe ndi mtengo wake.
Njira zothetsera makampani
Ngakhale zofooka zomwe tatchulazi, makampani opanga zida zopangira zida zamagetsi apanga pang'ono zofooka za granite kudzera muukadaulo waukadaulo:

Mapangidwe apangidwe kaphatikizidwe: Imatengera kuphatikiza kwa "granite base + chitsulo chimango", poganizira zonse zolimba komanso zopepuka (mwachitsanzo, wopanga makina ena a photolithography amapaka zisa za aluminiyamu m'munsi mwa granite, kuchepetsa kulemera kwake ndi 40%).
Zida zopangira zopangira: Pangani zida za ceramic masanjidwewo (monga silicon carbide ceramics) ndi miyala yopangira epoxy resin kuti ayese kukhazikika kwamafuta ndi kugwedezeka kwa granite, kwinaku mukukulitsa kusinthasintha kwa kukonza.
Ukadaulo waukadaulo waukadaulo: Poyambitsa ma aligorivimu a AI kuti akwaniritse njira yopangira, kuyerekezera kupsinjika kuti mulosere kuwopsa kwa ming'alu, ndikuphatikiza kuzindikira kwapaintaneti kuti musinthe magawo munthawi yeniyeni, kuchuluka kwa zotsalira zakusintha kwachepetsedwa kuchoka pa 5% mpaka pansi pa 1%.
Chidule
Zofooka za granite mumakampani opangira zida zopangira zida zamagetsi zimachokera kumasewera omwe ali pakati pa zinthu zachilengedwe ndi zofuna zamakampani. Ndi kupita patsogolo kwaukadaulo komanso kupanga zida zina, mawonekedwe ake ogwiritsira ntchito amatha kuchepa pang'onopang'ono kupita ku "zigawo zoyambira zosasinthika" (monga njanji zowongolera za hydrostatic zamakina a Photolithography ndi nsanja zoyezera molondola kwambiri), pomwe pang'onopang'ono zikupereka njira zosinthika zosinthika zaukadaulo pazinthu zosafunikira kwambiri. M'tsogolomu, momwe mungagwirizanitse ntchito, mtengo ndi kukhazikika zidzakhala nkhani yomwe makampani akupitiriza kufufuza.
