2. Fais fab Electronics

Hauv cov khoom siv hluav taws xob hluav taws xob xws li insulated gate bipolar transistors (IGBTs) thiab high-power diodes, ZTA substrates tau ua haujlwm vim lawv cov thermal conductivity thiab hluav taws xob rwb thaiv tsev muaj peev xwm. Qhov no tso cai rau kom muaj cua sov kom zoo thiab txhim khu kev qha ntawm cov khoom siv no.

3. LED Ntim

Lub teeb Emitting Diodes (LEDs) yog ib feem tseem ceeb ntawm cov cuab yeej teeb pom kev zoo niaj hnub no. ZTA substrates yog siv nyob rau hauv LED ntim vim lawv thermal stability thiab hluav taws xob rwb thaiv tsev, uas pab tswj kev ua tau zoo thiab ntev ntawm LEDs.

4. Cov khoom siv ua haujlwm semiconductor

ZTA ceramic substrates kuj tseem siv rau hauv cov khoom siv rau kev ua cov khoom siv semiconductor. Lawv zoo heev txhua yam muaj zog thiab tsis kam mus rau tshuaj corrosion ua rau lawv haum rau daim ntaub ntawv xws li wafer tuav thiab deposition txheej txheem.

5. Cov khoom siv kho mob

ZTA substrates yog siv nyob rau hauv daim ntawv thov kev kho mob, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov implantable electronics li pacemakers thiab neurostimulators. Lawv biocompatibility, siab mechanical zog, thiab hluav taws xob rwb thaiv tsev zog ua rau lawv xaiv zoo tagnrho rau cov kev siv tseem ceeb.

Kev tsim cov txheej txheem ntawm ZTA Ceramic Substrate

1. Kev npaj hmoov

High-zoo zirconia thiab alumina hmoov yog sib tov nyob rau hauv meej piv. Cov hmoov no feem ntau tau los ntawm cov txheej txheem xws li sol-gel synthesis lossis nag lossis daus.

2. Kev tsim

Cov hmoov sib tov yog tom qab ntawd ua rau hauv daim ntawv xav tau siv cov txheej txheem xws li qhuav nias, isostatic nias, lossis txhaj tshuaj molding. Cov kauj ruam no tsim lub cev ntsuab nrog lub hom phiaj substrate.

3. Sintering

Lub cev ntsuab yog raug rau qhov kub-kub sintering txheej txheem nyob rau hauv ib qho chaw tswj. Cov txheej txheem no densifies cov khoom, uas ua rau ib tug tag nrho consolidated ZTA ceramic substrate nrog rau cov khoom uas xav tau.
