Iyo etching process inzira yakajairika nhasi. Inowanzoshandiswa pakugadzira simbi. Mabhodhi edu akajairika, PCB mitsetse, mapaneru ekusimudza, sirin'i yesimbi isina tsvina, nezvimwewo, kazhinji vanoshandisa etching maitiro mukugadzira kwavo. Kazhinji kutaura, zvinoenderana nerudzi rwezvinhu zviri kuiswa, iyo etching maitiro inogona kukamurwa muzvikamu zvinotevera:
Kuyerera kwemaitiro: yakakwenenzverwa kana bhurashi ndiro yemhangura kuchenesa pamusoro → kudhinda skrini neingi yefotoresistive, kudhinda magirafu uye zvinyorwa → kuomesa → etching pre-kurapwa → kuchenesa → kuona → etching → kuchenesa → kuchenesa → kuchenesa → kubviswa kwechidziviriro chinodzivirira layer → mvura inopisa kuchenesa → kuchenesa mvura inotonhora → mushure mekurapa → chigadzirwa chapera.
Mafambiro eMafambiro: Kucheneswa Kwepasi Pepurati Yekudhinda → Kudhinda Yekudhinda Liquid Ingi → Kuomesa → Kuratidzwa → Gadziriso → Kusuka → Kuomesa → Kuongorora uye Kuona → Kuomesa Firimu → Kushongedza → Kubvisa Inodzivirira Layer → Kusuka.
Kuyerera Kwekuita: Kucheneswa kweplate pamusoro → mvura photoresist screen kudhinda inki → kuomesa → kuratidzwa → kusimudzira → kugezesa → kuomesa → tarisa uye simbisa → kuomeswa kwefirimu → alkaline dip kurapwa (alkaline etching) → de-inking (photosensitive etching inki yekuchenesa →) kugeza.
Pasinei neipi etching process inoshandiswa kune chero chinhu, danho rekutanga nderekusarudza iyo inki yakakodzera. Izvo zvinowanzodiwa pakusarudzwa kweinki yakanaka kushora, asidhi uye alkali kuramba, yakakwirira nhanho kugadziriswa, inogona kudhinda mitsetse yakanaka, etching kudzika kuzadzisa zvinodiwa zvekugadzira, mutengo unonzwisisika.
Photosensitive Blue Ink Etching Blue Ink ndeyepamusoro resolution yekutemera inki yekudhinda skrini. Inogona kushandiswa se etching ingi yeakadhindwa edunhu mabhodhi uye seanodzivirira anti-etching ingi yesimbi isina tsvina uye aruminiyamu pamusoro. Photosensitive Blue Oil inogona kuisa mitsetse yakanaka, kazhinji kusvika pakadzika 20 microns. Kuti ubvise inki, ingonyura mu 5% aqueous sodium hydroxide solution kwemasekonzi 60-80 pa tembiricha yemvura ye55-60°C. Iyo inki inogona kunyatsobviswa.
Ehe, ingi dzakatorwa kunze kwenyika dzinoratidza bhuruu dzekunyora dzinodhura kupfuura ingi dzakajairwa dzebhuruu. Kana iyo etching zvinodiwa zvisina kunyanya kujeka, unogona kushandisa mudzimba yekuzviomesa inki, senge zviratidzo zvekushambadzira, magonhi esimbi asina tsvina uye zvichingodaro. Nekudaro, kana zvigadzirwa zve etching zvichida kurongeka, zvinokurudzirwa kushandisa kunze kwenyika photosensitive etching bhuruu kuti uwane emhando yepamusoro etching mafuta.
