Lub tshuab nqus tsev vacuum SMT lub tshuab nqus tsev vacuum

Yog li ntawd, kev ntsuas antifouling yuav tsum tau ua nyob rau ntawm qhov chaw ntawm vuam substrate thiab cov khoom nto. Xaiv qhov tsim nyog solder thiab teem ib tug tsim nyog welding kub nkhaus. Reflow welding yog txheej txheem nyuaj thiab tseem ceeb hauv T txheej txheem, suav nrog ntau yam kev tshawb fawb xws li kev tswj tsis siv neeg, cov khoom siv, kua tshuab, thiab metallurgy. Yuav kom ua tiav vuam zoo, nws yog ib qho tsim nyog yuav tsum tau kawm tob tob txog txhua yam ntawm vuam tshuab [1]. Nrog rau kev loj hlob ntawm ntau yam khoom siv hluav taws xob mus rau qhov me me, lub teeb yuag, thiab qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntim tshuab tsim cov khoom siv thev naus laus zis thev naus laus zis thev naus laus zis © Copyright 2020 |
Cov cheeb tsam no thiab thaj chaw calcination yog tsim thiab ua tiav siv tib lub high-temperature resistant steel casting. Qhov chaw tub yees. Lub tub yees muab faib ua peb theem. Hauv qab kawg ntawm thawj ntu yog tsim thiab ua tiav rau hauv lub nkoj zoo li. Hom kev tsim no yog tsim los kom ceev cov dej ntws. Txhawm rau kom tsis txhob muaj adhesion ntawm cov av thiab lwm yam khoom thaiv cov dej ntws, ua rau muaj qhov kub thiab txias hauv qab thiab tawg ntawm calcined qhov chaw. Txhawm rau ua kom yooj yim rau kev ntxuav cov av, ntxuav qhov qhib hauv txhua qhov chaw. Cov lus nug nquag nug hauv daim ntawv thov yuav tsum nruj me ntsis txwv rau daim ntawv thov kub thiab tswj nyob rau hauv thaj tsam ntawm 1120 txog 1150 degree, txwv tsis pub lub neej kev pab cuam ntawm txoj siv conveyor yuav luv heev.
Qhov kev tshem tawm feem ntau yuav tsum nyob nruab nrab ntawm {{0}}.01 thiab 0.1 hli. Piv rau fusion vuam, thaum brazing, lub hauv paus hlau tsis yaj, tsuas yog cov solder melts; Piv nrog rau lub siab vuam, tsis muaj lub siab siv rau lub vuam thaum lub sij hawm brazing. Lub weld tsim los ntawm brazing yog hu ua brazing seam. Cov hlau muab tub lim siv rau brazing yog hu ua solder. Cov txheej txheem brazing: Tom qab ntxuav qhov chaw, lub workpiece yog sib sau ua ke nyob rau hauv ib tug lapped qauv, thiab lub solder yog muab tso rau ze los yog nruab nrab ntawm qhov sib txuas. Thaum lub workpiece thiab solder yog rhuab mus rau ib tug kub me ntsis siab tshaj qhov melting point ntawm lub solder, lub solder melts (lub workpiece tsis yaj), thiab yog nqus nyob rau hauv thiab ntim ntawm cov khoom workpiece qhov khoob los ntawm capillary ua. Cov kua nplaum thiab cov hlau ua haujlwm sib txawv thiab yaj ib leeg, ua ib qho kev sib koom ua ke tom qab condensation.
Nyob rau hauv xyoo tas los no, nrog rau txoj kev loj hlob sai ntawm kev tswj vaj huam sib luag tsim kev lag luam, Suav manufacturers tau nce ntau lawm, thiab kev sib txuas ntawm cov khoom siv thiab kev xav tau ntawm cov khoom lag luam tau yooj yim yooj yim. Cov neeg tsim khoom tau nyuam qhuav pib muab qhov tseem ceeb rau kev txhim kho "zoo" ntawm cov khoom muag. Cov ntaub ntawv tswj vaj huam sib luag tsim kev lag luam yuav txhim kho rau siab pixel interfaces, ramps, nyias cov phiaj xwm, lub teeb yuag, khoov tau, siab dynamic HDR, siab sib txawv, thiab dav xim gamut, uas ua rau muaj qhov tshwm sim ntawm Mini LEDs. Raws li kev kwv yees kwv yees, Mini-LED yuav tshaj tawm qhov tshwm sim xyoo no thiab nkag mus rau theem kev lag luam.
Lub tshuab nqus tsev aluminium brazing rauv yog tsuas yog siv rau lub tshuab nqus tsev vacuum ntawm tsheb radiators, cua txias evaporators, condensers, intercoolers, radar daim phiaj kav hlau txais xov, waveguides, thiab ntau hom phaj warped los yog tubular tshav kub exchangers. Lub tshuab nqus tsev kub kub brazing rauv yog qhov tsim nyog rau lub tshuab nqus tsev brazing ntawm stainless hlau, kub-kub alloy, nyuaj alloy, nonferrous hlau thiab lwm yam ntaub ntawv. Kev tshaj tawm xov xwm ntawm lub tshuab nqus tsev boilers: Tsis ntev los no, ob lub tshuab nqus tsev boilers nrog lub zog ntawm 14 megawatts tau ua tiav tiav rau hauv chav boiler ntawm Jidong Oilfield Base. Qhov no yog ib lub tshuab nqus tsev vacuum boiler nrog lub zog siab tshaj plaws hauv Suav teb, txhua qhov tuaj yeem ua tau raws li qhov xav tau cua sov ntawm 200000 square meters ntawm thaj chaw nyob. Lub tshuab nqus tsev vacuum boiler tshiab tau tsim los ntawm nws tus kheej. Qhov no yog lub tshuab nqus tsev vacuum boiler nrog qhov nruab nrab thermal efficiency ntawm 96 feem pua, uas yog 4 mus rau 5 feem pua ​​​​cov ntsiab lus siab dua li cov pa hluav taws xob boilers.
