Muhimmin La'akari:

• Saka idanu etching bayani maida hankali da zafin jiki don tabbatar da iri etching.
• Bincika akai-akai da maye gurbin etching mafita don kiyaye inganci.
• Yi amfani da kayan aikin aminci da ya dace da samun iska saboda yanayin haɗari na etching sinadarai.

4. Tsarin Plating

Kayan aiki da Dabaru:

• Plating mara amfani:Ajiye wani bakin ciki na jan ƙarfe akan ramukan da aka haƙa da kuma saman PCB, ƙirƙirar hanyoyin gudanarwa.
• Electroplating:Yana kauri Layer jan ƙarfe a saman kuma a cikin ramuka, haɓaka haɓaka aiki da ƙarfin injina.

Muhimmin La'akari:

• Tabbatar da tsaftacewa sosai da kunna saman PCB kafin plating.
• Saka idanu da abun da ke ciki da yanayi na plating wanka don cimma kauri iri ɗaya.
• A kai a kai duba ingancin plating don biyan takamaiman buƙatun.

5. Lamination na Copper

Kayan aiki da Dabaru:

• Injin Lamination:Yana amfani da foil na jan karfe zuwa ga PCB ta hanyar zafi da matsa lamba, yana tabbatar da layin jan karfe.
• Tsaftacewa da Shiryewa:Yana tabbatar da cewa ɓangarorin ɓangarorin da tagulla suna da tsabta don haɓaka mannewa.

Muhimmin La'akari:

• Sarrafa zafin jiki da matsa lamba don tabbatar da ko da mannewa na jan karfe.
• Kauce wa kumfa da wrinkles waɗanda zasu iya shafar haɗin kai da aminci.
• Gudanar da ingancin duba bayan lamination don tabbatar da daidaito da amincin layin jan karfe.

6. Hakowa

Kayan aiki da Dabaru:

• Injin hakowa na CNC:Daidai hukunce-hukuncen ramuka don vis, ramukan hawa, da abubuwan haɗin ramuka, masu ɗaukar girma da zurfi iri-iri.
• Haɗa Bits:Yawanci da aka yi daga tungsten carbide, waɗannan ragowa suna da dorewa kuma daidai.

Muhimmin La'akari:

• Bincika a kai a kai da kuma musanya ɗigogi don guje wa kuskuren hakowa.
• Sarrafa saurin hakowa da ƙimar ciyarwa don hana lalacewa ga kayan PCB.
• Yi amfani da tsarin dubawa na atomatik don tabbatar da daidaitaccen matsayi da girma.

7.Tsaftacewa da Binciken Ƙarshe

Kayan aiki da Dabaru:

• Kayayyakin Tsaftacewa:Yana kawar da ragowar sinadarai da gurɓatawa daga saman PCB, yana tabbatar da tsabta.
• Duban Kayayyakin Ƙarshe:An gudanar da shi da hannu don tabbatar da sahihancin sa da inganci gabaɗaya.

Muhimmin La'akari:

• Yi amfani da ma'auni masu dacewa da hanyoyin tsaftacewa don guje wa lalacewa ga PCB.
• Tabbatar da cikakken bincike na ƙarshe don ganowa da magance duk wasu lahani.
• Riƙe cikakkun bayanai da lakabi don gano kowane rukuni.

Kammalawa

Ƙirƙirar alamun PCB tsari ne mai rikitarwa kuma daidaitaccen tsari wanda ke buƙatar kayan aiki na musamman da kulawa sosai ga daki-daki. Kowane mataki, daga ƙira zuwa samuwar burbushi, dole ne a aiwatar da shi tare da babban daidaito don tabbatar da inganci da amincin PCB na ƙarshe. Ta hanyar bin ingantattun ayyuka da kuma kiyaye tsayayyen kulawar inganci, masana'antun za su iya samar da PCBs waɗanda suka dace da babban matsayi na aiki da dorewa, suna biyan buƙatun aikace-aikacen lantarki daban-daban.
