Izakhono zokusebenzisa imihla ngemihla zesithando sokutshisa i-vacuum

Isithando somlilo esitshiza i-vacuum sisetyenziselwa ikakhulu inkqubo yokutshiza izinto ze-semiconductor kunye nezixhobo zokulungisa amandla. Singasetyenziselwa ukutshiza i-vacuum, ukutshiza okukhuselwe yigesi kunye nokutshiza okuqhelekileyo. Sisixhobo senkqubo esitsha kuluhlu lwezixhobo ezikhethekileyo ze-semiconductor. Sinombono woyilo olutsha, ukusebenza okulula kunye nesakhiwo esincinci. Singagqibezela ukuhamba kweenkqubo ezininzi kwisixhobo esinye. Singasetyenziselwa unyango lobushushu be-vacuum, i-vacuum brazing kunye nezinye iinkqubo kwezinye iindawo.

Izakhono eziyimfuneko zokusebenzisa isithando sokutshisa i-vacuum

Isithando somlilo esishushu esinomoya ophezulu senzelwe ukuvelisa ubushushu obuphezulu kwi-tungsten crucible kwi-coil ngokusebenzisa umgaqo wokufudumeza okuphakathi kokungenisa umoya phantsi kokhuseleko lokuzalisa i-hydrogen emva kokucoca umoya, kwaye siqhubele phambili ukusebenza ngemitha yobushushu. Sifanelekile kuphando lwesayensi kunye neeyunithi zoshishino zomkhosi ukwenza nokutshiza umgubo wee-alloys ezichasene ne-refractory ezifana ne-tungsten, i-molybdenum kunye nee-alloys zazo. Indawo apho isithando sombane sifakwe khona kufuneka ihlangabezane neemfuno zococeko lwe-vacuum. Umoya ojikelezileyo kufuneka ucoceke kwaye wome, ube neemeko ezilungileyo zomoya. Indawo yokusebenza ayilula ukuphakamisa uthuli, njl.

Izakhono zokusebenzisa imihla ngemihla zesithando sokutshisa i-vacuum:

1. Jonga ukuba zonke izinto kunye nezixhobo kwikhabhinethi yokulawula ziphelele kwaye ziphelele na.

2. Ikhabhinethi yokulawula kufuneka ifakwe kwisiseko esifanelekileyo kwaye iqine.

3. Ngokwesazobe socingo, kwaye sibhekisa kwisazobe somatshini wombane, qhagamshela isekethe eyintloko yangaphandle kunye nesekethe yokulawula, kwaye uxhase ngokuqinileyo ukuqinisekisa ukuba ucingo luchanekile.

4. Qinisekisa ukuba inxalenye eshukumayo yesixhobo sombane kufuneka ihambe ngokukhululekileyo ngaphandle kokuxinana.

5. Ukumelana nobushushu akufuneki kube ngaphantsi kwe-2 megohms.

6. Zonke iivalvu zesithando sombane esingenamoya kufuneka zibe kwindawo evaliweyo.

7. Beka iswitshi yombane yokulawula kwindawo yokucima.

8. Jika iqhosha elilawula uxinzelelo ngesandla uliguqulele kwicala elichasene newotshi.

9. Beka iqhosha le-alamu kwindawo evulekileyo.

10. Gqibezela uqhagamshelo lwamanzi okupholisa olujikelezayo lwesixhobo ngokwesicwangciso. Kucetyiswa ukuba umsebenzisi aqhagamshele amanye amanzi amisiweyo (amanzi epompo) kumbhobho ophambili wokungena kunye nowokuphuma wesixhobo ukuthintela iringi yokutywina ukuba ingatshi ngenxa yokungasebenzi kakuhle kwamanzi ajikelezayo okanye ukusilela kombane.
