Direct Bond Copper Ceramic Substrate

Daim ntawv cog lus ncaj qha tooj liab (DBC) ceramic substrate, tseem hu ua ceramic circuit board lossis hlau ceramic substrate, yog ib hom tshwj xeeb ntawm hluav taws xob substrate siv hauv hluav taws xob siv hluav taws xob. Nws yog tsim los kom muaj txiaj ntsig zoo dissipate cua sov tsim los ntawm cov khoom siv hluav taws xob, ua rau nws tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntawv thov uas muaj lub zog loj muaj zog. Hauv qab no yog qee qhov tseem ceeb thiab cov yam ntxwv ntawm cov nyiaj ncaj qha tooj liab ceramic substrate.

Khoom siv

- Ceramic Txheej

Cov khoom siv hauv paus feem ntau yog cov thermal-conductivity ceramic, xws li txhuas oxide (Al2O3) lossis txhuas nitride (AlN). Cov ceramics no muab cov thermal stability zoo thiab hluav taws xob rwb thaiv tsev.

- Txheej tooj liab

Ntawm ib lossis ob sab ntawm cov ceramic, ib txheej ntawm high-purity tooj liab yog sib txuas. Cov txheej tooj liab no ua haujlwm raws li cov khoom siv hluav taws xob thiab tseem ua raws li lub tshuab hluav taws xob.

Direct Bonding txheej txheem
Cov txheej tooj liab yog sib txuas ncaj qha rau hauv cov khoom siv ceramic uas siv cov txheej txheem siab-kub, siab-siab. Qhov no ua kom muaj zog thiab thermally cuam tshuam ntawm cov tooj liab thiab ceramic txheej.

Qhov zoo

High Thermal conductivity

DBC substrates muaj thermal conductivity zoo heev vim muaj kev sib txuas ncaj qha ntawm cov tooj liab thiab ceramic txheej. Qhov no tso cai rau kom muaj cua sov kom zoo los ntawm cov khoom siv hluav taws xob.

Hluav taws xob rwb thaiv tsev

Cov khoom siv ceramic muab hluav taws xob rwb thaiv tsev, tso cai rau kev sib koom ua ke ntawm cov khoom siv hluav taws xob thiab cov khoom siv high-frequency ntawm tib lub substrate.

Mechanical Stability

Cov txheej txheem sib txuas ncaj qha tsim cov qauv ruaj khov uas tuaj yeem tiv taus thermal cycling thiab mechanical stress.

Daim ntawv thov

Fais fab Electronics

DBC substrates yog dav siv nyob rau hauv lub hwj chim hluav taws xob modules, xws li insulated rooj vag bipolar transistors (IGBTs), hwj chim diodes, thiab thyristors. Lawv yog cov tseem ceeb rau kev siv xws li lub cev muaj zog tsav, inverter, thiab converters.

LED Teeb pom kev zoo

Lawv yog siv los ua substrates rau high-power LED modules qhov twg thermal tswj yog qhov tseem ceeb heev.

Automotive Electronics

DBC substrates pom cov ntawv thov hauv hluav taws xob tsheb fais fab thiab lwm yam khoom siv hluav taws xob hauv tsheb.

Kev txiav txim siab tsim

- Txheej Thickness

Lub thickness ntawm cov ceramic thiab tooj liab txheej tuaj yeem ua raws li cov kev thov tshwj xeeb.

- Copper Trace Patterning

Cov txheej tooj liab tuaj yeem ua qauv tsim los tsim cov kab hluav taws xob thiab cov ntaub qhwv rau mounting cov khoom siv hluav taws xob.

- Tuag Attachment

Cov khoom siv semiconductor feem ntau txuas nrog rau txheej tooj liab siv cov khoom siv los yog lwm yam khoom siv high-thermal-conductivity.

Kev txiav txim siab nqi

DBC substrates zoo li yuav kim dua li cov qauv luam tawm Circuit Board (PCBs) vim yog cov khoom tshwj xeeb thiab cov txheej txheem tsim khoom.

Direct daim ntawv cog lus tooj liab ceramic substrates ua lub luag haujlwm tseem ceeb hauv kev nce qib ntawm cov tshuab hluav taws xob hluav taws xob, ua kom muaj zog ntau dua thiab siv hluav taws xob ntau dua. Lawv yog cov khoom tseem ceeb hauv kev lag luam uas yuav tsum muaj kev ua haujlwm siab hluav taws xob hluav taws xob.
