The etching process ndi yofala kwambiri masiku ano. Nthawi zambiri amagwiritsidwa ntchito popangira zitsulo. Zikwangwani zathu zodziwika bwino, mizere ya PCB, mapanelo okweza, denga lachitsulo chosapanga dzimbiri, ndi zina zambiri, nthawi zambiri amagwiritsa ntchito etching popanga. Nthawi zambiri, kutengera mtundu wazinthu zomwe zimakhazikika, njira yolumikizira imatha kugawidwa m'magulu otsatirawa:
Mayendedwe a njira: kuyeretsa mbale yamkuwa yopukutidwa kapena yopukutidwa → kusindikiza pansalu ndi inki yotchinga, zithunzi zosindikiza ndi zolemba → kuyanika → etching musanalandire chithandizo → kuyeretsa → kuzindikira → etching → kuyeretsa → etching → kuyeretsa → kuchotsa wosanjikiza wosindikiza wosindikiza → madzi otentha kuyeretsa → kuyeretsa madzi ozizira → mankhwala atatha → mankhwala omalizidwa.
Kuyenda kwa Njira: Kuyeretsa Pamwamba pa Puleti Yosindikizira → Inki Yosindikizira Yamawonekedwe a Liquid Photoresist → Kuyanika → Kuwonekera → Kutukuka → Kutsuka → Kuyanika → Kuyang’anira ndi Kutsimikizira → Kuumitsa Mafilimu → Etching → Kuchotsa Chigawo Chotetezera → Kuchapira.
Kuyenda kwa Njira: Kuyeretsa pamwamba pa mbale → inki yosindikizira yamadzimadzi → kuyanika → kuwonetseredwa → chitukuko → kuchapa → kuyanika → fufuzani ndi kutsimikizira → kuumitsa filimu → mankhwala a dip a alkaline (alkaline etching) → de-inking (kuyeretsa kwa inki →) kutsuka.
Mosasamala kanthu kuti ndi njira iti yolumikizira yomwe imagwiritsidwa ntchito pazinthu zilizonse, gawo loyamba ndikusankha inki yoyenera. Zomwe zimafunikira pakusankhidwa kwa inki ndizabwino kukana dzimbiri, kukana kwa asidi ndi alkali, kusamvana kwakukulu, kumatha kusindikiza mizere yabwino, etching kuya kukwaniritsa zofunika kupanga, mtengo wake ndi wololera.
Photosensitive Blue Ink Etching Blue Ink ndi inki yojambula bwino kwambiri yosindikiza pazithunzi. Itha kugwiritsidwa ntchito ngati inki yokhotakhota pama board osindikizidwa komanso ngati inki yotchinga yoteteza zitsulo zosapanga dzimbiri ndi aluminiyamu. Photosensitive Blue Oil imatha kuyika mizere yabwino, nthawi zambiri mpaka kuya kwa ma microns 20. Kuti muchotse inki, ingolowetsani mu 5% yamadzimadzi sodium hydroxide solution kwa masekondi 60-80 pamadzi otentha a 55-60 ° C. Inki ikhoza kuchotsedwa bwino.
Zowona, inki zojambulidwa za buluu zobwera kunja ndizokwera mtengo kuposa inki wamba zabuluu. Ngati zofunikira za etching sizili zolondola kwambiri, mutha kugwiritsa ntchito inki yowumitsa m'nyumba, monga zotsatsa, zitseko zokweza zitsulo zosapanga dzimbiri ndi zina zotero. Komabe, ngati mankhwala etching amafuna mwatsatanetsatane wachibale, tikulimbikitsidwa kugwiritsa ntchito kunja photosensitive etching buluu kupeza apamwamba etching mafuta.
