Etching yog siv los nthuav tawm cov txheej txheem ntawm cov hlau los ntawm kev xaiv tshuaj tua kab Nws kuj tshem tawm cov txheej nyias nyias, deformed heev qhia thaum sib tsoo thiab polishing. Nyob rau hauv alloys nrog ntau tshaj ib theem, etching tsim qhov sib txawv ntawm cov cheeb tsam sib txawv los ntawm qhov sib txawv ntawm topography los yog reflectivity.
Lub hom phiaj ntawm kev etching yog dab tsi?
Etching yog cov txheej txheem tshuaj lom neeg lossis electrolytic siv tom qab Metallographic sib tsoo thiab polishing txheej txheem. Etching Txhim kho qhov sib txawv ntawm qhov chaw kom pom qhov Microstructure lossis Macrostructure.
Yuav ua li cas thiab ua li cas?
Etching yog intaglio printmaking txheej txheem uas cov kab lossis thaj chaw raug siv cov kua qaub rau hauv cov phaj hlau txhawm rau tuav tus number case. Txhawm rau npaj lub phaj rau etching, nws yog thawj zaug polished kom tshem tawm tag nrho cov khawb thiab qhov tsis zoo ntawm qhov chaw. …
Vim li cas semiconductors xav tau etching?
Semiconductor Etching. Daim duab 1. … Hauv kev tsim khoom siv hluav taws xob semiconductor, etching yog hais txog txhua yam thev naus laus zis uas yuav xaiv cov khoom siv los ntawm cov yeeb yaj kiab nyias ntawm lub substrate(nrog lossis tsis muaj cov qauv ua ntej ntawm nws qhov chaw) thiab los ntawm qhov kev tshem tawm no tsim cov qauv ntawm cov khoom ntawd ntawm lub substrate.
Vim li cas koj ua hlau?
Txawm hais tias nws tau nyob ib puag ncig ntau pua xyoo, nws tau dhau los ua cov txheej txheem ntau zuj zus siv hauv kev tsim khoom lag luam. Hlau etching tso cai rau cov tuam txhab tsim khoom tsim cov qauv tsim mus tas li - lossis lwm yam duab pom - ntawm cov hlauNws yog qhov txhim khu kev qha thiab siv tau ntev dua li lwm cov txheej txheem tsim.
