Txheej txheem cej luam Ntawm Cov Khoom Tseem Ceeb Rau Alumina Relay Ceramic Lub Hnab Rau Lub Tsheb Hluav Taws Xob

Raws li kev lag luam hluav taws xob txuas ntxiv mus rau qhov siab dua thiab kev ntseeg siab, Alumina Relay Ceramic Lub hnab ntawv rau Lub Tsheb Hluav Taws Xob, nrog nws cov txiaj ntsig zoo tshaj plaws, thermal conductivity, noo noo tsis kam, txhua yam muaj zog, thiab rwb thaiv tsev tsis kam, tau siv dav hauv kev ntim khoom ntawm ntau yam khoom siv, suav nrog hybrid integrated circuits, optoelectronic devices, deg acoustic yoj, siv lead ua acoustic yoj. solid- xeev relays. Nto-mount enclosures uas tsim los siv cov txheej txheem ntau txheej ceramic tsis tsuas yog muaj kev ntseeg tau zoo tab sis kuj khav theeb qhov zoo hauv - nplai ntau lawm thiab tus nqi zoo- ua kom muaj txiaj ntsig, ntxiv dag zog rau lawv qhov kev nkag mus rau hauv kev lag luam loj xws li kev sib txuas lus, kev lag luam lasers, cov neeg siv khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob hauv tsheb, dhau los ua cov khoom siv hluav taws xob zoo {5} kev txhawb nqa.

Qhov loj - teev loj ntau lawm ntawm Metallization ntawm Aluminium Ceramics cia siab rau ib tug ua tiav core raw khoom system. Nws cov txheej txheem ntau lawm suav nrog ntau theem tseem ceeb. Ua ntej, cov hmoov ceramic yog tov nrog cov organic binders thiab cov kuab tshuaj, thiab tom qab ntawd ceramic ntsuab zaj duab xis ntawm cov thicknesses tshwj xeeb yog tsim los ntawm dov, extrusion, lossis casting txheej txheem. Tom qab ntawd, ntsuab ceramic qhov chaw yog tsim los ntawm cov kauj ruam xws li luam ntawv hlau muab tshuaj txhuam, pwm tsim, stacking, thiab lamination. Tom qab tshem tawm cov binder, ceramic matrix ​​sintered, thiab hlau qhov chaw yog ces brazed mus rau lub ceramic matrix. Tom qab electrolytic nickel plating thiab kub plating, cov khoom raug tshuaj xyuas thiab xa. Multilayer ceramic cov ntaub ntawv, luam ntawv pastes, txhuas thav duab, sealing nplhaib cov ntaub ntawv, cov ntaub ntawv kub dab dej, thiab solder ua ke yog cov tseem ceeb raw cov ntaub ntawv uas yuav tsum tau rau nws ntau lawm.

Raws li EV HVDC Relay Ceramic Housing, cov khoom siv ceramics siv hauv cov khoom siv ceramics ncaj qha txiav txim siab nws qhov kev ua tau zoo, thiab feem ntau muab faib ua ob pawg loj: siab-cov ntaub ntawv kub kub (HTCC) thiab qis-cov ntaub ntawv kub (LTCC). High -cov ntaub ntawv kub kub ceramic feem ntau muaj xws li alumina, beryllium oxide, thiab txhuas nitride. Alumina, vim nws qhov sib xyaw ua ke ntawm cov neeg kho tshuab siab zog thiab cov khoom siv rwb thaiv tsev zoo heev, yog cov khoom siv dav tshaj plaws. Nyob ntawm cov ntsiab lus alumina, alumina ceramics ntawm qib sib txawv (90%, 92%, 96%) tuaj yeem siv los ua kom tau raws li ntau yam kev thov. Tsawg-cov ntaub ntawv kub ceramic feem ntau yog siv cov iav ceramics, uas nws cov khoom yog zoo- haum rau qis- qhov kub thiab txias ntim, ntxiv rau qhov siab - cov ntaub ntawv kub kub ceramic.

Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev ua kom cov cua sov ua haujlwm thiab kev sib txuas lub zog ntawm Alumina Metallized Ceramics, feem. Rau cov tsev nyob hauv cov khoom siv hluav taws xob siv hluav taws xob, tungsten- tooj liab thiab molybdenum- cov khoom siv hluav taws xob tooj liab, nrog cov coefficients ntawm thermal expansion zoo ib yam li ceramics, nyiam dua. Molybdenum- cov ntaub ntawv tooj liab muaj kev ua tau zoo heev, tso cai rau cov ntaub ntawv nyias nyias thiab stamping, thiab feem ntau yog siv rau cov dab dej kub nrog cov vaj tsev tiaj tus. Tungsten- cov ntaub ntawv tooj liab xav tau cov hmoov metallurgy tsim thiab feem ntau yog tuab, ua rau lawv haum rau loj dua ceramic vaj tsev kub dab dej. Lub solder siv feem ntau yog nyiaj - tooj liab solder, nrog lub melting point ntawm 779℃. Lub brazing kub yog tswj ntawm 850 thiab 900℃kom ntseeg tau tias muaj kev sib txuas ntawm cov hlau thiab cov khoom siv ceramic.

Tam sim no, txoj kev loj hlob sai ntawm cov kev lag luam tshiab xws li 5G kev sib txuas lus, kev txawj ntse, thiab lub zog tshiab tsheb tau tsav tsheb nce ntxiv hauv kev thov rau Precision Metalized Ceramics, muab cov kev xav tau siab dua ntawm lawv cov kev ua tau zoo thiab tsav tsheb txuas ntxiv thiab txhim kho cov khoom siv raw. Qhov kev thov nyob rau hauv lub zog tshiab lub tsheb sector yog tshwj xeeb yog tseem ceeb. Peb cov khoom tseem ceeb nruj me ntsis siv siab- zoo alumina ceramic substrates, ua ke nrog cov khoom tsim nyog tungsten-raws li cov hlau pastes thiab nyiaj- tooj liab solders, muaj siab airtightness, siab rwb thaiv tsev, thiab zoo heev tshav kub dissipation, zoo kawg nkaus haum cov ntim yuav tsum tau ntawm high -voltage kev ua hauj lwm nyob rau hauv ntau yam kev ua hauj lwm ntawm DC.

Nyob rau hauv lub neej yav tom ntej, nrog kev tsis tu ncua ntawm cov khoom siv thev naus laus zis, cov hlau -ceramic raw khoom yuav raug txhim kho ntxiv. Kev ua kom zoo ntawm cov khoom siv raw thiab kev tswj cov nqi yuav dhau los ua qhov tseem ceeb rau kev txhim kho kev lag luam, txuas ntxiv txhawb kev hloov pauv, hloov kho dua tshiab, thiab siab - kev txhim kho zoo ntawm kev lag luam hluav taws xob. PebAlumina Relay Ceramic hnab ntawv rau Fais Tshebyog txhim khu kev qha thiab muaj nyob rau hauv ib tug ntau yam ntawm specifications. Peb kuj tuaj yeem kho nws kom tau raws li koj cov kev xav tau tshwj xeeb. Peb zoo siab tos txais cov lus nug thiab kev txiav txim los ntawm txhua tus neeg siv khoom los koom tes tshawb nrhiav kev lag luam tshiab hauv kev lag luam ceramic encapsulation rau lub zog tshiab tsheb.
