Yog. 304 stainless hlau tuaj yeem vuam rau tooj liab hauv lub tshuab nqus tsev siv ntau hom thiab cov tshuaj ntxiv rau kev vuam (BFM). Cov hlau filler uas ua los ntawm kub, nyiaj thiab nickel tuaj yeem ua haujlwm tau. Vim tias tooj liab nthuav dav me ntsis ntau dua li 304 stainless hlau, yuav tsum tau saib xyuas tshwj xeeb rau qhov kev teeb tsa kev sib txuas. Hauv qhov no, lub zog ntawm tooj liab yuav qis heev, yog li nws tuaj yeem haum rau stainless hlau yam tsis pom kev hloov pauv.
Feem ntau cov khoom sib dhos ua los ntawm cov hlau sib xyaw ua ke yuav ua haujlwm ntawm qhov kub txog li 4 ° Kelvin. Muaj kev xav txog kev tsim qauv thiab kev txwv, tab sis cov hlau kub thiab nyiaj uas siv rau hauv cov khoom siv feem ntau yog siv rau daim ntawv thov no.
3. Kuv xav tau vuam ib qho khoom sib dhos uas nyuaj heev, tab sis kuv tsis paub yuav vuam txhua yam ib zaug li cas. Puas siv tau vuam ntau kauj ruam ntawm cov khoom sib xyaw?
Yog! Ib tus kws tshaj lij soldering tuaj yeem npaj cov txheej txheem soldering ntau kauj ruam. Xav txog cov khoom siv hauv paus thiab BFM kom cov pob qij txha qub tsis yaj hauv kev khiav tom qab. Feem ntau, thawj lub voj voog khiav ntawm qhov kub siab dua li cov voj voog tom qab thiab BFM tsis rov yaj hauv cov voj voog tom qab. Qee zaum BFM ua haujlwm heev hauv kev sib kis cov khoom xyaw rau hauv lub substrate uas rov qab mus rau tib qhov kub yuav tsis ua rau rov yaj. Kev soldering ntau kauj ruam tuaj yeem yog ib qho cuab yeej yooj yim thiab ua haujlwm tau zoo rau kev tsim cov khoom siv kho mob kim.
Qhov teeb meem no daws tau! Muaj ntau txoj hauv kev los tiv thaiv qhov no, txoj hauv kev zoo tshaj plaws yog siv BFM kom raug. Yog tias qhov sib koom ua ke me me thiab me me hauv thaj chaw, nws yuav zoo li xav tsis thoob tias yuav tsum muaj BFM ntau npaum li cas los txuas qhov sib koom ua ke kom zoo. Xam thaj chaw cubic ntawm qhov sib koom ua ke thiab sim siv BFM ntau dua li thaj chaw xam. Tus qauv tsim ntawm qhov sib txuas pluggable yog lub qhov (socket) tho qhov, zoo ib yam li txoj kab uas hla sab hauv ntawm lub raj, uas tso cai rau BFM txav mus ncaj qha mus rau txoj kab uas hla sab hauv ntawm lub raj los ntawm kev ua capillary. Tawm chav ntawm qhov kawg ntawm lub raj kom tiv thaiv kev ua capillary, lossis tsim qhov txuas kom lub raj tuaj yeem tawm me ntsis dhau thaj chaw sib txuas. Cov txheej txheem no tsim txoj hauv kev nyuaj dua rau BFM mus ncig mus rau qhov kawg ntawm lub raj, yog li txo qhov kev pheej hmoo ntawm kev txhaws.
Cov ncauj lus no tshwm sim los ntawm lub sijhawm mus rau lub sijhawm thiab yuav tsum tau tham txog. Tsis zoo li cov solder fillets, uas tsim kom muaj zog hauv qhov sib koom ua ke, cov solder fillets loj tsis nkim BFM thiab tuaj yeem ua rau muaj kev phom sij. Qhov tseem ceeb yog dab tsi nyob sab hauv. Qee cov PMs yog brittle hauv cov fillets loj vim yog qhov concentration ntawm cov khoom tsis-diffusing qis melting point Cheebtsam. Hauv qhov no, txawm tias muaj qhov qaug zog me ntsis, cov fillet tuaj yeem tawg thiab loj hlob mus rau qhov tsis ua haujlwm loj heev. Thaum soldering, me me, txuas ntxiv mus ntawm BFM ntawm qhov sib koom ua ke feem ntau yog qhov tsim nyog tshaj plaws rau kev tshuaj xyuas pom.
