Uninzi lwabantu lucinga "igumbi lokucoca" njengendawo eyenzelwe ukugcina uthuli lungangeni. Kwi-metrology echanekileyo kunye nokuhlanganiswa kwezixhobo zegranite, ulawulo lothuli yinxalenye nje yomsebenzi - umngeni omkhulu wobunjineli kukugcina ubushushu kunye nokungcangcazela kuzinzile ngokwaneleyo ukuba izixhobo zokulinganisa ngokwazo azibi ngumthombo wempazamo.
Kutheni Ulawulo Lobushushu Luza Kuqala?
Zonke izinto ziyanda kwaye zincipha ngobushushu. Intsimbi, igranite, kunye ne-aluminium zonke zine-coefficients ezahlukeneyo zokwandiswa kobushushu, oko kuthetha ukuba ukujika kwe-1–2°C kubushushu begumbi kunokutshintsha isiseko esikhulu segranite okanye irula yokulinganisa ende ngesixa esilinganiswayo - esaneleyo ukuba sibaluleke xa ukunyamezela kuchazwe kwii-microns. Yiyo loo nto amagumbi e-precision metrology ahlala egcinwe kubushushu obuqhelekileyo (ngokuqhelekileyo yi-20°C, ngokwe-ISO kunye nemigangatho emininzi yelizwe) ngolawulo oluqinileyo lokufuma ukuthintela ukufunxwa komswakama kwizinto ezinemingxuma kunye nokugqwala kwizixhobo zesinyithi kunye neegeyiji.
Ukugcina olo zinzo ngomlinganiselo omkhulu akuyongxaki ye-HVAC kuphela. Amagumbi akhelwe le njongo adla ngokusebenzisa umgangatho wekhonkrithi oqinisiweyo ongaphezulu kwe-500mm ubukhulu ukunciphisa ukuguquguquka kobunzima bobushushu kunye nokuguquguquka kwesakhiwo, kuba umgangatho oshushu ngokungalinganiyo phantsi kwelanga okanye umthwalo wezixhobo uya kujika kancinci - kwaye "kancinci" yile nto kanye umlinganiselo wokuchaneka ozama ukuyisusa.
Ukwahlula ukungcangcazela kwihlabathi langaphandle
Kwanegumbi elilawulwa kakuhle bubushushu linokuphazamiseka kukungcangcazela okuvela kwizixhobo ezikufutshane, izithuthi ezidlulayo, okanye ukuhamba ngeenyawo. Yiyo loo nto izixhobo ezichanekileyo zakha imisele yokwahlulahlula - izithuba ezisikiweyo kumgangatho ojikeleze umngcelele wegumbi lokulinganisa, ezidla ngokuba ngamakhulu aliqela eemilimitha ububanzi kunye nemitha okanye ngaphezulu nzulu - ukuze zihlukanise isiseko segumbi kwisakhiwo esijikelezileyo.
Iikhreyini ezingaphezulu ezisetyenziselwa ukuhambisa izinto zegranite enzima okanye zesinyithi zinomngeni ohambelanayo: ikhreyini eqhelekileyo yemizi-mveliso inokungenisa ukungcangcazela okwaneleyo ngexesha lokusebenza ukuphazamisa izixhobo ezinobuthathaka xa zilinganiswa phakathi. Izakhiwo ezithatha oku nzulu zityala imali kwiinkqubo zekhreyini ezingcangcazelayo okanye "ezithuleyo" ngokukodwa ezisetyenziselwa ngaphakathi kwamagumbi e-metrology, ukuze ukuhambisa into yokusebenza kungawucimi umsantsa igumbi elakhelwe ukubonelelwa ngawo.
Iindawo zokuhlanganisa ezilungiselelwe ngokweMisebenzi yeSemiconductor
Ukudibanisa ulwakhiwo lwegranite — ukudibanisa, ukulungelelanisa, kunye nokufakela okukhuluizinto ezichanekileyo— abanye abavelisi baya phambili baze bakhe iindawo zokuhlanganisa ezilungiselelweyo zesitayile segumbi lokucoca ezilungiselelwe ngokwemigangatho ye-semiconductor fab, nangona imveliso yokugqibela ingeyo-semiconductor. Ingqiqo ilula: ungcoliseko lwamasuntswana emoyeni ngexesha lokuhlanganisa lunokuchaphazela iindawo zokubopha kunye nokuba tyaba ixesha elide kanye njengokuba lunokuchaphazela inkqubo ye-wafer, ngoko ke uqeqesho olufanayo lokusingqongileyo luyasetyenziswa.
Into Onokuyithatha Kubathengi
Xa kuvavanywa umthengisi wecandelo elichanekileyo, imeko-bume esebenza kuyo ifektri yabo ayisiyonto yesibini — inxulumene ngqo nokuba imveliso egqityiweyo iya kukwazi na ukugcina unyamezelo lwayo oluchaziweyo xa iphuma kwifektri. Imibuzo efanelekileyo ukubuzwa ibandakanya: Lithini iqondo lobushushu kunye nebhendi yonyamezelo yegumbi lokuhlanganisa? Ngaba kukho ukuvaleka kokungcangcazela phakathi kwendawo yokulinganisa kunye nomgangatho wemveliso ngokubanzi? Ngaba iikhreyini kunye nezixhobo zokuphatha izinto zilinganiswe ngokusebenza okuncinci kokungcangcazela? Iimpendulo zityhila okungakumbi malunga nokuzinza kwemveliso ixesha elide kunalo naliphi na inani lephepha le-spec.
