Laga soo bilaabo gaashaanka elektromagnetic-ka ilaa kuwa aan magnet-ka ahayn: Sidee buu saldhigga granite u ilaaliyaa jawiga cabbiraadda dareemayaasha saxda ah ee sarreeya?

Goobaha cirifka leh sida soo saarista chip semiconductor iyo kormeerka saxda ah ee indhaha, dareemayaasha saxda ah ee saxda ah ayaa ah aaladaha ugu muhiimsan ee lagu helo xogta muhiimka ah. Si kastaba ha ahaatee, bay'ada korantada ee adag iyo xaaladaha jireed ee aan deganayn ayaa badanaa keena xogta cabbirka aan saxda ahayn. Saldhigga granite, oo leh qalabkiisa aan magnetic, gaashaanka lahayn iyo xasilloonida jireed ee aadka u wanaagsan, waxay dhistaa jawi cabbireed lagu kalsoonaan karo oo loogu talagalay dareenka.

Dabeecadda aan magnet-ka ahayn waxay gooysaa isha faragelinta
Dareemayaasha saxda ah ee saxda ah sida dareemayaasha barokaca inductive iyo miisaanka magnetic ayaa aad xasaasi ugu ah isbeddelada goobta magnetic. Magnetism-ka dabiiciga ah ee saldhigyada birta dhaqameedka ah (sida birta iyo aluminium alloy) waxay abuuri karaan goob bir ah oo faragelinaysa agagaarka dareemayaasha. Marka dareemaha uu shaqeynayo, faragelinta dibadda ee magnetic waxay la falgashaa goobta magnetic gudaha, taas oo si fudud u keeni karta leexinta xogta cabbirka.

Granite, sida dhagaxa dabiiciga ah ee dabiiciga ah, wuxuu ka kooban yahay macdanta sida quartz, feldspar iyo mica. Qaab-dhismeedkeeda gudaha ayaa go'aaminaya in aanay lahayn wax magnetism ah oo dhan. Ku rakib dareemaha saldhigga granite si aad u tirtirto faragelinta magnetic ee saldhigga xididka. Qalabka saxda ah sida mikroskoobyada elektarooniga ah iyo resonance magnetka nukliyeerka, saldhigga granite wuxuu hubinayaa in dareemehu uu si sax ah u qabto isbeddellada qarsoon ee shayga la beegsanayo, isaga oo iska ilaalinaya khaladaadka cabbirka ee ay keento faragelinta magnetic.
Sifooyinka qaab-dhismeedku waxa lagu xidhaa gaashaanka elektromagnetic
In kasta oo granite aanu lahayn awoodda gaashaandhigga sida biraha, qaab-dhismeedkiisa jidheed ee gaarka ah wuxuu sidoo kale wiiqi karaa faragelinta korantada. Granite waa mid ku adag qaab-dhismeedkiisa oo cufan qaab dhismeedkiisa. Habka isku dhafan ee kirismaska ​​macdanta ayaa sameeya caqabad jireed. Marka mowjadaha elektromagnetic-ka ee dibadda ay ku faafeen saldhigga, qayb tamarta ka mid ah waxaa nuuga kareemka oo u beddela tamarta kulaylka, qaybna way ka muuqataa oo ku kala firdhisan tahay dusha sare ee crystal, taas oo yaraynaysa xoogga hirarka korantada ee gaadhaya dareenka.

Codsiyada wax ku oolka ah, saldhigyada granite waxaa badanaa lagu daraa shabaqyada gaashaanka birta si loo sameeyo qaabab isku dhafan. Mesh bir ah ayaa xannibaya hirarka korantada ee soo noqnoqda, granite-kuna wuxuu sii wiiqaa faragelinta hadhaaga ah isagoo bixinaya taageero deggan. Aqoon-is-weydaarsiyada warshadaha oo ay ka buuxaan beddelayaasha soo noqnoqda iyo matoorada, isku-dhafkan ayaa awood u siinaya dareemayaasha inay si deggan ugu shaqeeyaan xitaa jawiga korantada ee xooggan.
Xasiji sifooyinka jirka oo xooji isku halaynta cabbirka
Isku-dhafka fidinta kulaylka ee granite aad ayuu u hooseeyaa (kaliya (4-8) ×10⁻⁶/℃), cabbirkeeduna aad buu isu beddelaa marka heerkulku is beddelo, iyada oo hubinaysa xasilloonida booska rakibaadda dareemayaasha. Waxqabadkeeda qoyaanka ah ee aadka u fiican waxay si dhakhso ah u nuugi kartaa gariirka deegaanka waxayna yareyn kartaa saameynta khalkhalgelinta farsamada ee cabbirada. Marka la eego cabbirka saxda ah ee indhaha, saldhigga granite wuxuu ka hortagi karaa dariiqa indhaha ee ay sababto qallafsanaanta kulaylka iyo gariirka, hubinta saxnaanta iyo ku celcelinta xogta cabbirka.

Xaaladda ogaanshaha dhumucda wafer semiconductor, ka dib markii shirkad gaar ah ay aqbashay saldhigga granite, qaladka cabbiraadda ayaa hoos uga dhacay ± 5μm ilaa ± 1μm gudahood. Qaabka iyo kormeerka dulqaadka booska ee qaybaha hawada sare, nidaamka cabbiraadda iyadoo la adeegsanayo saldhigga granite ayaa hagaajiyay ku celcelinta xogta in ka badan 30%. Kiisaskani waxay si buuxda u muujinayaan in saldhigga granite uu si weyn u wanaajinayo kalsoonida cabbirka ee dareemayaasha saxda ah ee saxda ah iyada oo la tirtirayo faragelinta elektromagnetic iyo xasilinta deegaanka jireed, taas oo ka dhigaysa qayb muhiim ah oo lagama maarmaan ah oo ku jirta goobta cabbirka saxda ah ee casriga ah.
