• Geometry thiab Thickness:Lub filament tus tsim, nrog rau nws txoj kab uas hla, thickness, thiab geometry, dictates nws stability. Ib tug zoo-engineered tsim muaj peev xwm tiv taus thermal kev nyuaj siab, optimizing nws cov kev pab cuam lub neej.

4. Deposition ib puag ncig

• Chemical Ib puag ncig:Reactive gases thiab cov kab mob nyob rau hauv lub deposition ib puag ncig yuav corrode tungsten filament, compromising nws cov qauv kev ntseeg.

• Vacuum Quality:Kev tuav lub tshuab nqus tsev zoo yog qhov tseem ceeb. Cov kab mob hauv lub tshuab nqus tsev tuaj yeem tso rau ntawm lub filament, hloov nws cov khoom thiab txo nws txoj sia.

5. Kev tuav thiab tu

• Kev Tiv Thaiv Kab Mob:Cov txheej txheem nruj rau kev tuav cov tungsten evaporation filaments, nrog rau cov hnab looj tes huv thiab cov cuab yeej, tiv thaiv kev sib kis uas yuav cuam tshuam rau kev ua haujlwm.

• Filament Cleaning:Tsis tu ncua, maj mam ntxuav ntawm cov filament tshem tawm cov kab mob sib kis, ncua nws lub neej yam tsis muaj kev puas tsuaj.

6. Kev caij tsheb kauj vab

Cycle zaus:Qhov zaus ntawm tig lub filament rau thiab tawm cuam tshuam nws lub neej. Kev caij tsheb kauj vab nquag qhia txog kev ntxhov siab thermal, uas tuaj yeem ua rau cov filament degrading.

7. Kev siv hluav taws xob zoo

Stable Power Supply:Kev hloov pauv lossis tsis ruaj khov hauv cov khoom siv hluav taws xob tuaj yeem cuam tshuam qhov ntsuas kub. Lub zog ruaj khov yog qhov tseem ceeb rau kev ua haujlwm zoo sib xws. 

8. Sputtering thiab Deposition nqi

Optimized Process Parameters:Kho sputtering thiab deposition tus nqi zoo yuav txo tau hnav thiab tsim kua muag ntawm tungsten filament, pab mus rau lub neej ntev kev pab cuam. 

9. Cov nqi cua sov thiab cua txias

Rate Control:Cov cua kub ntau dhau los yog cua txias qhia txog kev ntxhov siab thermal. Cov nqi tswj tau pab tswj cov neeg kho tshuab kev ruaj ntseg, txhawb nqa lub neej ntev. 

10. Cov qauv siv

Nruam vs. Kev ua haujlwm tsis sib xws:Kev nkag siab txog cov qauv siv yog qhov tseem ceeb. Kev ua haujlwm tsis tu ncua tuaj yeem ua rau hnav tsis tu ncua, thaum lub sijhawm ua haujlwm tsis tu ncua qhia txog thermal cycling kev ntxhov siab. 

11. Kev txhawb nqa zoo

Crucible Quality:Qhov zoo ntawm cov khoom siv crucible cuam tshuam lub filament lifespan. Kev xaiv thiab tu cov crucibles yog qhov tseem ceeb.

12. Filament Alignment

Alignment hauv Chamber:Kev sib raug zoo kom txo qis cov ntsiab lus kev ntxhov siab. Misalignment lossis cua sov tsis sib xws tuaj yeem ua rau muaj kev ntxhov siab hauv zos, txo cov filament tag nrho lub neej.

13. Kev soj ntsuam thiab kuaj mob

Filament Monitoring Systems:Kev siv cov kev soj ntsuam xyuas muab cov lus ceeb toom ntxov ntawm cov teeb meem uas yuav tshwm sim. Kev saib xyuas zoo raws li kev kuaj mob txhim kho filament ntev.

14. Cov khoom siv sib xws

Compatibility nrog Deposition Materials:Kev nkag siab txog cov khoom sib xws yog qhov tseem ceeb. Qee cov ntaub ntawv tso tawm tuaj yeem hnov ​​​​mob nrog tungsten, cuam tshuam cov filament txoj kev ncaj ncees.

15. Ua raws li cov lus qhia tshwj xeeb

Chaw tsim tshuaj paus Specifications:Kev nruj nruj rau cov chaw tsim khoom tshwj xeeb yog tsis sib tham. Deviations los ntawm cov kev pom zoo los yog cov kev coj ua yuav cuam tshuam lub filament lub neej ntev.

Hauv kev xaus, kev pab cuam lub neej ntawm tungsten evaporation filaments yog ib qho kev sib txuam ntawm ntau yam. Los ntawm kev tswj xyuas cov kev xav tau zoo thiab siv cov kev tiv thaiv kev tiv thaiv, cov neeg ua haujlwm tuaj yeem qhib tag nrho cov peev txheej ntawm tungsten evaporation filaments, kom ntseeg tau tias kev ua tau zoo thiab txhim khu kev qha hauv PVD txheej txheem.
