Cov ntsiab cai ntawm cov substrates thiab kev xaiv zaj duab xis

Thaum lub sijhawm npaj zaj duab xis, lub substrate tuaj yeem xaiv tau raws li qhov chaw quab yuam hauv qab no:

1. Raws li cov hom phiaj thov sib txawv, xaiv Kub Qhia lossis Alloy, Iav, Ceramics thiab Yas ua lub substrate;

2. Cov qauv ntawm cov khoom siv substrate yog sib xws rau cov qauv zaj duab xis;

3. Cov khoom siv substrate phim qhov kev ua tau zoo ntawm zaj duab xis kom txo qhov kev ntxhov siab thermal kom tiv thaiv cov zaj duab xis nyias kom tsis txhob poob:

Xav txog kev muab khoom hauv khw, tus nqi thiab qhov nyuaj ntawm kev ua tiav.

Cov ntsiab cai ntawm kev xaiv zaj duab xis:

① Kev sib raug zoo ntawm cov tshuaj lom neeg ntawm cov khoom siv thiab cov ntaub ntawv zaj duab xis. Qhov sib raug zoo ntawm cov tshuaj lom neeg zoo tshaj plaws txhais tau tias thaum lub sijhawm npaj zaj duab xis, qhov kev ua tau zoo ntawm qhov interface tsis poob qis, thiab cov theem tsis muaj kev cuam tshuam tshuaj lom neeg ntawm qhov interface.

② kev sib raug zoo ntawm cov khoom siv substrate thiab zaj duab xis. Kev sib raug zoo ntawm lub cev feem ntau yog hais txog kev sib phim ntawm cov khoom siv matrix thiab zaj duab xis hauv cov coefficient thermal expansion, elastic modulus, thiab lattice coefficient. Qhov tshwm sim cuam tshuam ncaj qha rau kev faib tawm ntawm kev ntxhov siab seem hauv cov khoom siv zaj duab xis, thiab tom qab ntawd cuam tshuam rau cov khoom siv kho tshuab ntawm zaj duab xis.
