Kuchokera pakutchinga kwa ma elekitiroma mpaka kusakhala ndi maginito: Kodi maziko a granite amateteza bwanji malo oyezera a masensa olondola kwambiri?

M'magawo ang'onoang'ono monga kupanga semiconductor chip ndi kuyang'anitsitsa bwino kwa kuwala, masensa apamwamba kwambiri ndi zipangizo zopezera deta yofunika kwambiri. Komabe, madera ovuta a electromagnetic komanso kusakhazikika kwakuthupi nthawi zambiri kumabweretsa data yolondola yoyezera. Maziko a granite, okhala ndi zinthu zopanda maginito, zotetezedwa komanso kukhazikika kwakuthupi, amamanga malo oyezera odalirika a sensa.

Chikhalidwe chopanda maginito chimadula gwero la kusokoneza
Masensa olondola kwambiri monga ma inductive displacement sensors ndi maginito masikelo amakhudzidwa kwambiri ndi kusintha kwa maginito. Maginito achilengedwe azitsulo zachitsulo (monga zitsulo ndi aluminiyamu alloy) amatha kupanga mphamvu ya maginito yosokoneza kuzungulira sensa. Sensa ikagwira ntchito, kusokoneza kwakunja kwa maginito kumalumikizana ndi maginito amkati, omwe angayambitse kusiyanasiyana kwa data.

Granite, monga mwala wachilengedwe woyaka moto, amapangidwa ndi mchere monga quartz, feldspar ndi mica. Mapangidwe ake amkati amatsimikizira kuti alibe maginito konse. Ikani sensa pa maziko a granite kuti muchotse kusokoneza kwa maginito kwa maziko kuchokera muzu. Pazida zolondola monga ma microscopes a electron ndi nyukiliya maginito resonance, maziko a granite amaonetsetsa kuti sensa imagwira molondola kusintha kosawoneka bwino kwa chinthu chomwe mukufuna, kupeŵa zolakwika za muyeso zomwe zimachitika chifukwa cha kusokoneza maginito.
Makhalidwe amapangidwe amagwirizanitsidwa ndi electromagnetic shielding
Ngakhale granite ilibe mphamvu yotchinga ngati zitsulo, mawonekedwe ake apadera amathanso kufooketsa kusokoneza kwa ma elekitiroma. Granite ndi yolimba m'mapangidwe ake komanso yowundana. Kuphatikizika kwa makristasi amchere kumapanga chotchinga chakuthupi. Pamene mafunde akunja a electromagnetic akufalikira kumunsi, gawo la mphamvuyo limatengedwa ndi kristalo ndikusandulika kukhala mphamvu ya kutentha, ndipo gawo likuwonekera ndikubalalika pamwamba pa kristalo, motero kuchepetsa mphamvu ya mafunde a electromagnetic kufika pa sensa.

Muzochita zogwiritsidwa ntchito, maziko a granite nthawi zambiri amaphatikizidwa ndi maukonde oteteza zitsulo kuti apange mapangidwe ophatikizika. Ma mesh achitsulo amatchinga mafunde amagetsi othamanga kwambiri, ndipo granite imafooketsanso kusokoneza kotsalira pomwe ikupereka chithandizo chokhazikika. M'misonkhano yamafakitale yodzaza ndi ma frequency converter ndi ma mota, kuphatikiza uku kumathandizira masensa kuti azigwira ntchito mokhazikika ngakhale pamalo amphamvu amagetsi.
Khazikitsani zinthu zakuthupi ndikuwonjezera kudalirika kwa miyeso
Coefficient of thermal expansion of granite ndi yotsika kwambiri (4-8) × 10⁻⁶/℃), ndipo kukula kwake kumasintha pang'ono pamene kutentha kumasinthasintha, kuonetsetsa kukhazikika kwa malo oyika sensa. Kuchita bwino kwake konyowa kumatha kuyamwa mwachangu kugwedezeka kwa chilengedwe ndikuchepetsa kusokonezeka kwa makina pamiyezo. Mu kuyeza kolondola kwa kuwala, maziko a granite amatha kuletsa njira yowunikira yomwe imayamba chifukwa cha kusintha kwa kutentha ndi kugwedezeka, kuwonetsetsa kulondola komanso kubwereza kwa data yoyezera.

Pankhani yozindikira makulidwe a semiconductor wafer, bizinesi ina itatengera maziko a granite, cholakwika choyezera chidatsika kuchokera ku ± 5μm mpaka mkati ± 1μm. Mu mawonekedwe ndi kulolerana kwa malo kuyang'ana kwa zigawo zamlengalenga, njira yoyezera pogwiritsa ntchito granite maziko yathandizira kubwereza kwa data ndi 30%. Milandu iyi ikuwonetsa bwino kuti maziko a granite amathandizira kwambiri kudalirika kwa kuyeza kwa masensa olondola kwambiri pochotsa kusokonezedwa ndi ma elekitiroma ndi kukhazikika kwa chilengedwe, ndikupangitsa kuti ikhale gawo lofunikira kwambiri pakuyezera kolondola kwamakono.
