Tsarin etching tsari ne na gama gari a yau. Yawancin lokaci ana amfani da shi don ƙaƙƙarfan ƙarfe. Allolinmu na yau da kullun na yau da kullun, layin PCB, fatunan ɗagawa, rufin bakin karfe, da sauransu, galibi suna amfani da tsarin etching a cikin samarwa. Gabaɗaya magana, bisa ga nau'in kayan da ake yi, ana iya raba tsarin etching zuwa nau'ikan masu zuwa:
Tsarin tsari: goge ko goge goge saman farantin jan ƙarfe → buguwar allo tare da tawada mai ɗaukar hoto, zane-zanen bugu da rubutu → bushewa tsaftacewa → tsaftace ruwa mai sanyi → bayan magani → gama samfurin.
Tsarin Tsara: Tsabtace Filaye na Farantin Buga → Fitar da allo Liquid Photoresist Ink → bushewa → Bayyanawa → Ci gaba → Rinsing → bushewa → Dubawa da Tabbatarwa → Harden Fim → Etching → Cire Layer Kariya → Rinsing.
Tsarin Tsara: Tsabtace farantin karfe → ruwa photoresist allo bugu tawada → bushewa → fallasa → ci gaba → rinsing → bushewa → duba da tabbatarwa → hardening fim → maganin alkaline tsoma (alkaline etching) → de-inking (photosensitive etching tawada tsaftacewa →) rinsing.
Ko da wane tsari ne ake amfani da shi don kowane abu, mataki na farko shine zaɓi tawada da ya dace. Bukatun gabaɗaya don zaɓin tawada shine juriya mai kyau na lalata, juriya acid da alkali, babban ƙuduri na lokaci, na iya buga layi mai kyau, zurfin etching don saduwa da buƙatun samarwa, farashin yana da ma'ana.
Photosensitive Blue Tawada Etching Blue Tawada babban ƙuduri ne na zanen tawada don buga allo. Ana iya amfani da shi azaman tawada etching don bugu na allunan kewayawa da kuma azaman tawada mai karewa don bakin karfe da saman aluminum. Mai ɗaukar hoto mai ɗaukar hoto yana iya fitar da layukan masu kyau, yawanci zuwa zurfin microns 20. Don cire tawada, kawai a jiƙa a cikin maganin sodium hydroxide mai ruwa 5% na tsawon daƙiƙa 60-80 a zafin ruwa na 55-60 ° C. Ana iya cire tawada yadda ya kamata.
Tabbas, shigo da tawada masu zanen shuɗi masu ɗaukar hoto sun fi tsada fiye da tawada shuɗi na yau da kullun. Idan buƙatun etching ba su yi daidai ba, zaku iya amfani da tawada mai bushewa na gida, kamar alamun talla, kofofin ɗaga bakin karfe da sauransu. Koyaya, idan samfuran etching suna buƙatar daidaitaccen dangi, ana ba da shawarar yin amfani da shuɗi mai ɗaukar hoto mai ɗaukar hoto don samun ingantaccen mai etching.
