Dab tsi yog tooj liab substrate?

Copper substrate yog qhov kim tshaj plaws hlau substrate, thiab nws cov thermal conductivity yog ntau zaus zoo dua li ntawm txhuas thiab hlau substrates.

Feem ntau, muaj immersion kub tooj liab substrates, silver-plated tooj liab substrates, tin-txheej tooj liab substrates, thiab anti-oxidation tooj liab substrates. Lub voj voog txheej ntawm tooj liab substrate yuav tsum muaj lub peev xwm nqa tau loj, yog li yuav tsum siv cov ntawv ci tooj liab tuab dua, nrog lub thickness ntawm feem ntau 35μm ~ 280μm; Cov txheej txheem thermal rwb thaiv tsev yog cov thev naus laus zis ntawm tooj liab substrate, thiab cov tub ntxhais thermal conductive Cheebtsam yog Al2O3 thiab silicon hmoov Cov muaj pes tsawg leeg yog tsim los ntawm epoxy resin puv polymers, nrog thermal tsis kam (0.15), zoo viscoelastic zog, thermal aging kuj, thiab muaj peev xwm tiv taus mechanical thiab thermal stress. Lub hauv paus hlau txheej ntawm tooj liab substrate yog cov neeg txhawb nqa ntawm tooj liab substrate, uas yuav tsum tau muaj thermal conductivity, feem ntau yog cov phaj tooj liab, tab sis cov phaj tooj liab tuaj yeem siv tau (cov phaj tooj liab tuaj yeem muab cov thermal conductivity zoo dua). .
