Cov txheej txheem etching yog txheej txheem ntau heev niaj hnub no. Nws feem ntau yog siv rau hlau etching. Peb cov ntawv tshaj tawm ib txwm muaj, cov kab PCB, nqa vaj huam sib luag, stainless hlau qab nthab, thiab lwm yam, feem ntau siv cov txheej txheem etching hauv lawv cov khoom. Feem ntau hais lus, raws li hom khoom raug etched, txheej txheem etching tuaj yeem muab faib ua pawg hauv qab no:
Cov txheej txheem ntws: polished lossis txhuam tooj liab phaj nto ntxuav → tshuaj ntsuam luam ntawv nrog photoresistive number case, luam ntawv duab thiab ntawv → ziab → etching ua ntej kho → tu → nrhiav → etching → tu → etching → tu → tshem tawm cov tshuaj ntsuam luam ntawv tiv thaiv txheej → dej kub ntxuav → dej txias ntxuav → tom qab kho → khoom tiav.
Cov txheej txheem ntws: Nto huv ntawm cov ntawv luam ntawv → Cov ntawv luam tawm ua kua Photoresist Ink → Qhuav → nthuav tawm → Kev loj hlob → Rinsing → ziab → Tshuaj ntsuam xyuas thiab pov thawj → Zaj duab xis Hardening → Etching → Tshem tawm cov txheej tiv thaiv → Rinsing.
Cov txheej txheem ntws: Plate nto ntxuav → kua photoresist npo luam ntawv number case → ziab → raug → kev loj hlob → yaug → ziab → xyuas thiab xyuas → zaj duab xis hardening → alkaline dip kho (alkaline etching) → de-inking (photosensitive etching number case ntxuav →) yaug.
Txawm hais tias tus txheej txheem etching yog siv rau txhua yam khoom, thawj kauj ruam yog xaiv tus cwj mem tsim nyog. Cov kev cai dav dav rau kev xaiv tus cwj mem yog qhov zoo corrosion kuj, acid thiab alkali tsis kam, siab theem daws teeb meem, tuaj yeem luam cov kab zoo, etching qhov tob kom tau raws li qhov yuav tsum tau ua, tus nqi tsim nyog.
Photosensitive Blue Ink Etching Blue Ink yog lub siab daws teeb meem engraving number case rau kev tshuaj ntsuam luam ntawv. Nws tuaj yeem siv los ua tus cwj mem etching rau cov ntawv luam tawm hauv Circuit Court boards thiab ua tus tiv thaiv etching number case rau stainless hlau thiab txhuas qhov chaw. Photosensitive Blue Roj tuaj yeem ua cov kab zoo, feem ntau mus rau qhov tob ntawm 20 microns. Txhawm rau tshem tawm tus cwj mem, tsuas yog tsau hauv 5% aqueous sodium hydroxide tov rau 60-80 vib nas this ntawm dej kub ntawm 55-60 ° C. Tus cwj mem tuaj yeem raug tshem tawm zoo.
Tau kawg, imported photosensitive xiav engraving inks yog kim dua li cov xim xiav inks. Yog tias cov kev cai etching tsis yog qhov tseeb, koj tuaj yeem siv tus kheej lub tshuab ziab khaub ncaws, xws li cov ntawv tshaj tawm, lub qhov rooj nqa stainless hlau thiab lwm yam. Txawm li cas los xij, yog tias cov khoom siv etching xav tau cov txheeb ze precision, nws raug nquahu kom siv cov khoom siv etching xiav kom tau txais cov roj zoo etching.
