Kwezogesi, ibhodi lesifunda eliphrintiwe (PCB) liwumgogodla wemishini eminingi kagesi.Ngenkathi ukwakhiwa kwama-PCB athuthukile kuvame ukwenziwa ngochwepheshe, ukwenza ama-PCB anezinhlangothi ezimbili ekhaya kungaba inketho engabizi kakhulu futhi esebenzayo kwezinye izimo.Kule bhulogi, sizoxoxa ngesinyathelo ngesinyathelo senqubo yokwenza i-PCB ezinhlangothi zombili endaweni yokunethezeka kwekhaya lakho.
1. Qoqa izinto ezidingekayo:
Ngaphambi kokungena ohlelweni lokukhiqiza, kubalulekile ukuqoqa zonke izinto ezidingekayo.Lokhu kufaka phakathi ama-laminates agqoke i-copper, omaka unomphela, amaphrinta we-laser, i-ferric chloride, i-acetone, i-drill bits, i-copper-plated wire, nezinto zokuphepha ezifana namagilavu nezibuko.
2. Dizayina isakhiwo se-PCB:
Usebenzisa isofthiwe yokuklama ye-PCB, dala uhlelo lwesekethe ye-elekthronikhi ofuna ukuyakha.Ngemuva kokuthi uhlelo seluqediwe, dweba ukwakheka kwe-PCB, ubeke izingxenye ezihlukene nemikhondo njengoba kudingeka.Qiniseka ukuthi isakhiwo sifanele i-PCB enezinhlangothi ezimbili.
3. Phrinta isakhiwo se-PCB:
Phrinta isakhiwo se-PCB ephepheni elicwebezelayo usebenzisa iphrinta ye-laser.Qiniseka ukuthi ufaka isibuko isithombe sivundlile ukuze sidlulele ngendlela efanele ebhodini le-copper clad.
4. Isakhiwo sokudlulisa:
Sika isakhiwo esiphrintiwe bese usibeka sibheke phansi ebhodini le-copper clad.Yivikele endaweni nge-tape futhi uyishise ngensimbi phezu kokushisa okuphezulu.Cindezela ngokuqinile cishe imizuzu eyi-10 ukuze uqinisekise ukusatshalaliswa kokushisa okulinganayo.Lokhu kuzodlulisela uyinki ephepheni iye epuleti lethusi.
5. Etching plate:
Susa ngokucophelela iphepha ebhodini le-copper clad.Manje uzobona isakhiwo se-PCB sidluliselwa endaweni yethusi.Thela i-ferric chloride eyanele endishini yepulasitiki noma yengilazi.Gcoba ibhodi kusixazululo se-ferric chloride, uqiniseke ukuthi limbozwe ngokuphelele.Gcoba ngobumnene isixazululo ukusheshisa inqubo yokufaka.Khumbula ukugqoka amagilavu nezibuko phakathi nalesi sinyathelo.
6. Hlanza futhi uhlole ibhodi lesekhethi:
Ngemuva kokuthi inqubo yokufaka isiqediwe, ibhodi lisuswa kwisisombululo futhi lihlanjululwe ngamanzi abandayo.Sika imiphetho bese ukhuhla kahle ibhodi ngesipontshi ukuze ususe uyinki oweqile bese uqopha izinsalela.Yomisa ibhodi ngokuphelele futhi uhlole noma yimaphi amaphutha okungenzeka noma izinkinga.
7. Ukumba:
Usebenzisa i-drill enencanyana, mba izimbobo ngokucophelela ku-PCB ezindaweni eziqokiwe zokubekwa kwengxenye nokusoda.Qiniseka ukuthi imbobo ihlanzekile futhi ayinayo yonke imfucumfucu yethusi.
8. Izingxenye zokushisela:
Beka izingxenye zikagesi nhlangothi zombili ze-PCB futhi uzivikele ngeziqeshana.Sebenzisa i-soldering iron kanye ne-solder wire ukuxhuma izingxenye emithonjeni yethusi.Thatha isikhathi sakho futhi uqinisekise ukuthi amalunga e-solder ahlanzekile futhi aqinile.
Ekuphetheni:
Ngokulandela le miyalo yesinyathelo nesinyathelo, ungenza ngempumelelo i-PCB enamacala amabili ekhaya.Nakuba inqubo ingase ekuqaleni ihilele ukuzama kanye nephutha, ngokuzijwayeza nokunaka imininingwane, ungakwazi ukuzuza imiphumela yobungcweti.Khumbula njalo ukubeka ukuphepha kuqala, gqoka izinto zokuzivikela ezifanele futhi usebenze endaweni engenawo umoya.Ngakho-ke vula ubuhlakani bakho bese uqala ukwakha ama-PCB akho anezinhlangothi ezimbili!
