Basic Introduction to Hlau Etching

Feem ntau hu ua hlau etching, tseem hu ua photochemical hlau etching, hais txog kev tshem tawm cov yeeb yaj kiab tiv thaiv ntawm thaj chaw hlau etching tom qab raug phaj ua thiab kev loj hlob. Thaum lub sij hawm hlau etching, nws los rau hauv kev sib cuag nrog cov tshuaj tov kom ua tiav cov nyhuv ntawm dissolution thiab corrosion, tsim concave convex los yog hollow duab. Keeb kwm yog siv los tsim cov ntawv luam tawm xws li tooj liab thiab zinc phaj, nws kuj tau siv dav hauv kev ua cov khoom siv hluav taws xob txo qhov hnyav, cov ntawv teev npe, thiab nyias cov khoom ua haujlwm uas nyuaj rau kev siv cov txheej txheem ua ib txwm ua; Tom qab kev txhim kho txuas ntxiv thiab txhim kho cov txheej txheem cov cuab yeej, nws kuj tuaj yeem siv rau kev ua cov khoom siv hlau etching rau cov khoom siv hluav taws xob nyias nyias hauv aviation, machinery, thiab tshuaj industries. Tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem semiconductor, hlau etching yog ib qho cuab yeej siv tsis tau.
