Emasimini asezingeni eliphezulu njengokukhiqiza ama-chip e-semiconductor kanye nokuhlolwa kokukhanya okunembile, izinzwa ezinembile kakhulu ziyizinto eziyinhloko zokuthola idatha ebalulekile. Kodwa-ke, izindawo eziyinkimbinkimbi ze-electromagnetic kanye nezimo zomzimba ezingazinzile zivame ukuholela kudatha yokulinganisa enganembile. Isisekelo se-granite, esinezakhiwo zaso ezingezona ezikagesi, ezivikelwe kanye nokuqina komzimba okuhle kakhulu, sakha indawo yokulinganisa ethembekile yenzwa.
Imvelo engeyona eyomagnetic inquma umthombo wokuphazamiseka
Izinzwa ezinembile kakhulu njengezinzwa zokufuduka ezibangela ukuguquka kanye nezikali zesikali sikamagnetic zizwela kakhulu ezinguqukweni ensimini yamagnetic. Uzibuthe oluyimvelo lwezisekelo zensimbi zendabuko (njengensimbi kanye ne-aluminium alloy) lungadala insimu yamagnetic ephazamisayo ezungeze inzwa. Lapho inzwa isebenza, insimu yamagnetic ephazamisayo yangaphandle ixhumana nensimu yamagnetic yangaphakathi, okungabangela kalula ukuphambuka kwedatha yokulinganisa.
I-granite, njengedwala eliyi-igneous lemvelo, yakhiwe ngamaminerali afana ne-quartz, i-feldspar kanye ne-mica. Isakhiwo sayo sangaphakathi sinquma ukuthi ayinayo nhlobo i-magnetism. Faka i-sensor esisekelweni se-granite ukuze ususe ukuphazamiseka kwamagnetic kwesisekelo kusuka empandeni. Ezinsimbini zokunemba ezifana nama-electron microscope kanye ne-nuclear magnetic resonance, isisekelo se-granite siqinisekisa ukuthi i-sensor ibamba ngokunembile izinguquko ezincane zento eqondiwe, igweme amaphutha okulinganisa abangelwa ukuphazamiseka kwamagnetic.
Izici zesakhiwo zihambisana nokuvikela kwe-electromagnetic
Nakuba i-granite ingenalo ikhono lokuvikela ugesi njengezinsimbi, isakhiwo sayo esiyingqayizivele somzimba singanciphisa ukuphazamiseka kwe-electromagnetic. I-granite iqinile ekubunjweni futhi iqinile ngesakhiwo. Ukuhlelwa okuhlangene kwamakristalu amaminerali kwakha isithiyo esibonakalayo. Lapho amaza kagesi angaphandle esakazeka esisekelweni, ingxenye yamandla imuncwa yi-crystal bese iguqulwa ibe amandla okushisa, bese ingxenye ibonakaliswa futhi ihlakazeke ebusweni bekristalu, ngaleyo ndlela kunciphisa ukuqina kwamaza kagesi afinyelela ku-sensor.
Ezisetshenzisweni ezisebenzayo, izisekelo zegranite zivame ukuhlanganiswa namanethi okuvikela insimbi ukuze kwakhiwe izakhiwo ezihlanganisiwe. I-mesh yensimbi ivimba amaza kagesi asebenzisa imvamisa ephezulu, kanti igranite yenza buthaka ukuphazamiseka okusele ngenkathi inikeza ukwesekwa okuzinzile. Ema-workshop ezimboni agcwele ama-frequency converters nama-motor, le nhlanganisela yenza izinzwa zisebenze kahle ngisho nasendaweni enamandla kagesi.
Qinisa izakhiwo zomzimba futhi uthuthukise ukuthembeka kokulinganisa
I-coefficient yokwanda kokushisa kwe-granite iphansi kakhulu (kuphela (4-8) ×10⁻⁶/℃), futhi usayizi wayo awushintshi kakhulu lapho izinga lokushisa lishintshashintsha, okuqinisekisa ukuzinza kwendawo yokufaka inzwa. Ukusebenza kwayo okuhle kakhulu kokudambisa kungamunca ngokushesha ukudlidliza kwemvelo futhi kunciphise ithonya lokuphazamiseka kwemishini ekulinganisweni. Ekulinganisweni kokukhanya okunembile, isisekelo se-granite singavimbela ukususwa kwendlela yokukhanya okubangelwa ukuguqulwa kokushisa nokudlidliza, okuqinisekisa ukunemba nokuphindaphindwa kwedatha yokulinganisa.
Esimweni sokutholwa kobukhulu be-semiconductor wafer, ngemuva kokuba ibhizinisi elithile lithathe isisekelo se-granite, iphutha lokulinganisa lehle kusuka ku-±5μm laya ngaphakathi kwe-±1μm. Ekuhlolweni kokubekezelelana kwesimo nendawo kwezingxenye zezindiza, uhlelo lokulinganisa olusebenzisa isisekelo se-granite luthuthukise ukuphindaphindwa kwedatha ngaphezu kuka-30%. Lawa macala abonisa ngokugcwele ukuthi isisekelo se-granite sithuthukisa kakhulu ukuthembeka kokulinganisa kwezinzwa ezinembe kakhulu ngokuqeda ukuphazamiseka kwe-electromagnetic kanye nokuzinzisa indawo ebonakalayo, okwenza kube yingxenye ebalulekile ebalulekile ensimini yokulinganisa ngokunemba yesimanje.
