Cov txheej txheem Active Hlau Brazing (AMB) yog kev txhim kho ntxiv ntawm DBC thev naus laus zis. Nws siv ib qho me me ntawm cov khoom siv xws li Ti, Zr, Cr hauv cov hlau muab tub lim kom hnov mob nrog cov ceramic los tsim cov txheej txheem tshuaj tiv thaiv uas tuaj yeem ntub dej los ntawm cov kua muab tub lim hlau, thiaj li ua rau cov khoom siv sib txuas nrog cov hlau txheej. AMB substrate yog raws li cov tshuaj tiv thaiv ntawm ceramic thiab cov hlau nquag ntawm qhov kub thiab txias kom ua tiav kev sib xyaw ua ke, yog li nws muaj zog dua kev sib txuas thiab kev ntseeg tau zoo dua. Cov txheej txheem hlau tseem muab txheej txheej metallization rau cov txheej txheem ceramic, uas tuaj yeem txo cov sijhawm ua haujlwm thiab tus nqi ntawm PCB.
Nta ntawm Active Hlau Braze Ceramic PCB
Siab dua thermal conductivity
Lub thermal conductivity ntawm ceramic substrates yog ntau dua li cov tsoos organic substrates, uas ua rau AMB ceramic PCBs haum rau high-power daim ntaub ntawv uas yuav tsum tau npaum li cas tshav kub dissipation.
Kev sib txuas ntau dua
Vim lub AMB ceramic PCB yog raws li cov tshuaj tiv thaiv ntawm ceramics thiab active ntsiab ntawm qhov kub thiab txias, uas ua rau nws muaj zog bonding ntau dua lwm yam ceramics.
Kev ntseeg siab dua
Cov txheej txheem hlau ua haujlwm ua kom muaj zog thiab ruaj khov ntawm cov txheej txheem ceramic thiab cov txheej txheem hlau, uas tuaj yeem txhim kho kev ntseeg tau ntawm PCB.
Cov khoom hluav taws xob zoo heev
Ceramic substrates muaj tsawg dielectric qhov tsis tu ncua thiab poob, uas tuaj yeem txo cov teeb liab poob thiab cuam tshuam hauv kev siv ntau zaus.
Nqi-zoo
Lub active hlau txheej muab ib txheej metallization rau cov ceramic substrate, uas tuaj yeem txo lub sijhawm ua haujlwm thiab tus nqi ntawm PCB. (Tab sis lwm txoj hauv kev, AMB kev tsim khoom xav tau cov cuab yeej kim.)
Tsis yog txhua yam zoo meej, AMB ceramic kuj muaj nws qhov tsis zoo.
Brittle / fragile: Ceramic substrates yog nkig ntau dua li cov organic substrates, uas
tej zaum yuav ua rau muaj kev pheej hmoo ntawm kev tawg lossis tawg thaum tsim khoom lossis sib dhos, yog li ua tib zoo thaum sib dhos lossis hloov pauv.
Txwv tsis pub muaj kev ywj pheej: Ceramic substrates muaj qhov hloov pauv yooj yim, uas tuaj yeem txwv qhov tsim
kev xaiv ntawm PCB.
Daim ntawv thov ntawm Active Hlau Braze Ceramic PCB
AMB ceramic PCBs tau siv dav hauv kev siv hluav taws xob siab thiab kev ntseeg siab, xws li hluav taws xob hluav taws xob, aerospace, thiab kev siv tub rog. Hauv cov khoom siv hluav taws xob hluav taws xob, AMB ceramic PCBs feem ntau yog siv rau hauv high-power inverters, lub cev muaj zog tsav, thiab cov khoom siv hluav taws xob, qhov chaw thermal conductivity thiab kev ntseeg siab yog qhov tseem ceeb. Hauv kev siv dav hlau thiab tub rog, AMB ceramic PCBs yog siv rau hauv avionics, radars, thiab kev sib txuas lus, qhov twg yuav tsum muaj kev ntseeg siab thiab hnyav ib puag ncig.
