Nhoroondo, nzira yekudzikisa, kana etching process, yakagadziridzwa gare gare, asi nhasi ndiyo inonyanya kushandiswa.Iyo substrate inofanira kunge iine simbi yesimbi, uye kana zvikamu zvisingadiwi zvabviswa zvese zvasara ndeye conductor pateni.Nekudhinda kana kutora mafoto ese akafumurwa mhangura inosarudzwa yakanamirwa nemasiki kana corrosion inhibitor kudzivirira yaidiwa conductive pateni kubva mukukuvadzwa, uye ipapo aya akavharidzirwa laminates kana mapepa emhangura anoiswa mu etching midziyo iyo sprites inopisa etching agents pamusoro pendiro.Iyo etching agent inoshandura kemikari iyo mhangura yakazaruka kuita musanganiswa unonyungudika kusvika nzvimbo dzese dzakafumurwa dzanyungudika uye pasina mhangura yasara.Firimu rinobvisa rinobva rashandiswa kubvisa firimu nemakemikari, kubvisa corrosion inhibitor uye kusiya chete muenzaniso wemhangura.Iyo muchinjiko-chikamu chemhangura conductor yakati wandei trapezoidal, nekuti kunyangwe iyo yakatwasuka etching mwero yakakwidziridzwa mune yakagadziridzwa yekupfapfaidza etching dhizaini, iyo etching ichiri kuitika pasi nekudivi.Iyo inoguma conductor yemhangura ine padivi madziro tilt isina kunaka, asi inogona kushandiswa.Kune zvakare mamwe mamwe maconductor graphic ekugadzira maitiro anogona kugadzira akamira padivi pemadziro.
Nzira yekudzikisa ndeyekusarudza kubvisa chikamu chemhangura foil pamusoro pemhangura-clad laminate kuti uwane conductive pattern.Kubvisa ndiyo nzira huru yekugadzirwa kwedunhu rakadhindwa mazuva ano.Kubatsira kwayo kukuru kwakakura, kwakagadzikana uye kwakavimbika maitiro.
Nzira yekudzikisa inonyanya kugoverwa muzvikamu zvina zvinotevera:
Kudhinda skrini: (1) yakanaka kumberi dhizaini dhizaini inogadzirwa kuita sirika skrini mask, sirika sikirini haidi dunhu pachikamu inovharwa newakisi kana zvinhu zvisingapinde mvura, wobva waisa mask yesilika muPCB isina chinhu iri pamusoro. iyo skrini haizogadzirwe pabesmear zvakare inodzivirira, isa mapuranga edunhu mumvura etching, haisi chikamu chevhavha yekudzivirira ichave ngura, pakupedzisira iyo inodzivirira mumiriri.
(2) optical printing kugadzirwa: yakanaka yekumusoro dhizaini yedunhu dhizaini pane inotenderera kune yakareruka firimu mask (nzira iri nyore ndeye kushandisa printa yakadhindwa masiraidhi), kuve chikamu cheopaque color printing, yobva yaputirwa nechiedza-sensitive pigment pane isina chinhu. PCB, inogadzirira firimu rakanaka pandiro mumushini wekuratidzwa, bvisa firimu mushure mebhodhi redunhu nemugadziri we graphical kuratidzwa, pakupedzisira inotakura padunhu etch.
(3) Kuveza kugadzirwa: zvikamu zvisingadiwi pamutsetse usina chinhu zvinogona kubviswa zvakananga nekushandisa mubhedha wepfumo kana laser engraving muchina.
(4) Kudhinda kwekutamisa kupisa: Iwo edunhu magirafu anodhindwa pabepa rekutamisa kupisa nelaser printer.Iwo edunhu magiraidhi epepa rekutamisa anotamirwa kune yemhangura yakavharwa ndiro nemuchina wekupisa wekupisa wekudhinda, uyezve dunhu rinoiswa.
