Photochemical Metal Etching
Kugwiritsa Ntchito Mapangidwe Othandizira Pakompyuta (CAD)
Njira yopangira chitsulo chojambula zithunzi imayamba ndikupanga mapangidwe pogwiritsa ntchito CAD kapena Adobe Illustrator.Ngakhale kupanga ndi sitepe yoyamba, si mapeto a kuwerengera makompyuta.Kumasulira kwatha, makulidwe achitsulo amatsimikiziridwa komanso chiwerengero cha zidutswa zomwe zidzakwanira pa pepala, chinthu chofunikira chochepetsera mtengo wopangira.Mbali yachiwiri ya makulidwe a pepala ndikutsimikiza kwa kulolerana kwa gawo, komwe kumadalira miyeso ya gawolo.
Njira yopangira chitsulo chojambula zithunzi imayamba ndikupanga mapangidwe pogwiritsa ntchito CAD kapena Adobe Illustrator.Komabe, uku sikuwerengetsera kokha pakompyuta komwe kumakhudzidwa.Pambuyo pomaliza kupanga, makulidwe achitsulo amatsimikiziridwa, komanso chiwerengero cha zidutswa zomwe zingagwirizane ndi pepala kuti zichepetse ndalama zopangira.Kuonjezera apo, kulolerana kwa gawo kumadalira miyeso ya gawo, yomwe imakhalanso ndi makulidwe a pepala.
Kukonzekera kwachitsulo
Mofanana ndi kuyika kwa asidi, chitsulocho chiyenera kutsukidwa bwino chisanayambe kukonzedwa.Chitsulo chilichonse chimatsukidwa, kutsukidwa ndi kutsukidwa pogwiritsa ntchito mphamvu ya madzi ndi zosungunulira zofatsa.Njirayi imachotsa mafuta, zonyansa, ndi tinthu tating'onoting'ono.Izi ndi zofunika kupereka yosalala woyera padziko ntchito photoresist filimu bwinobwino kutsatira.
Mapepala Othira Zitsulo okhala ndi Makanema Olimbana ndi Photoresistant
Lamination ndi ntchito photoresist filimu.Mapepala achitsulo amasunthidwa pakati pa odzigudubuza omwe amavala ndi kuyika mofanana ndi lamination.Pofuna kupewa kuwonekera mosayenera kwa mapepala, ndondomekoyi imamalizidwa m'chipinda choyatsidwa ndi magetsi achikasu kuti zisawonongeke ndi kuwala kwa UV.Kuyanjanitsa koyenera kwa mapepala kumaperekedwa ndi mabowo okhomeredwa m'mphepete mwa mapepala.Mavuvu mu zokutira laminated amatetezedwa ndi vacuum kusindikiza mapepala, amene flattens zigawo laminate.
Kukonzekera zitsulo za photochemical metal etching, ziyenera kutsukidwa bwino kuchotsa mafuta, zonyansa, ndi particles.Chitsulo chilichonse chimatsukidwa, kutsukidwa, ndikutsukidwa ndi zosungunulira pang'ono komanso kuthamanga kwa madzi kuti zitsimikizire kuti pamakhala malo osalala komanso oyera pogwiritsira ntchito filimu ya photoresist.
Chotsatira ndi lamination, chomwe chimaphatikizapo kugwiritsa ntchito filimu ya photoresist pazitsulo zachitsulo.Mapepala amasunthidwa pakati pa odzigudubuza kuti azivala mofanana ndikugwiritsa ntchito filimuyo.Njirayi imachitika m'chipinda chokhala ndi chikasu kuti chiteteze kuwala kwa UV.Mabowo okhomeredwa m'mphepete mwa mapepalawo amapereka mayanidwe oyenera, pamene kusindikiza kwa vacuum kumapangitsa kuti zigawo za laminate zisamapangidwe ndikulepheretsa thovu kupanga.
Photoresist Processing
Panthawi yokonza photoresist, zithunzi zochokera ku CAD kapena Adobe Illustrator rendering zimayikidwa pamtundu wa photoresist pa pepala lachitsulo.Kumasulira kwa CAD kapena Adobe Illustrator kumadindidwa mbali zonse za chitsulocho pozimanga mozungulira ndi pansi pa chitsulocho.Mapepala achitsulo akayika zithunzizo, amawonekera ku kuwala kwa UV komwe kumayika zithunzizo kwamuyaya.Kumene kuwala kwa UV kumawalira m'madera omveka bwino a laminate, photoresist imakhala yolimba ndikuuma.Madera akuda a laminate amakhalabe ofewa komanso osakhudzidwa ndi kuwala kwa UV.
Mugawo lopangira photoresist la etching yachitsulo cha photochemical, zithunzi zochokera ku CAD kapena Adobe Illustrator design zimasamutsidwa pagawo la photoresist pa pepala lachitsulo.Izi zimachitika ndi kusanjikiza kapangidwe kake ndi pansi pa pepala lachitsulo.Zithunzizo zikagwiritsidwa ntchito pazitsulo zachitsulo, zimawonekera ku kuwala kwa UV, zomwe zimapangitsa zithunzizo kukhala zosatha.
Pakuwonekera kwa UV, malo owoneka bwino a laminate amalola kuwala kwa UV kudutsa, zomwe zimapangitsa kuti photoresist ikhale yolimba komanso yolimba.Mosiyana ndi izi, madera akuda a laminate amakhalabe ofewa komanso osakhudzidwa ndi kuwala kwa UV.Njirayi imapanga chitsanzo chomwe chidzatsogolera ndondomeko yokongoletsera, kumene madera olimba adzakhalabe ndipo madera ofewa adzachotsedwa.
Kupanga Mapepala
Kuchokera ku photoresist processing, mapepalawa amapita ku makina omwe akukula omwe amagwiritsa ntchito njira ya alkali, makamaka sodium kapena potaziyamu carbonate solutions, yomwe imatsuka filimu yofewa ya photoresist kusiya mbali zake kuti ziwoneke.Njirayi imachotsa kukana kofewa ndikusiya kukana kolimba, komwe ndi gawo loyenera kukhazikika.Mu chithunzi chomwe chili pansipa, madera owuma ali a buluu, ndipo madera ofewa ndi imvi.Madera omwe sanatetezedwe ndi laminate yowuma ndi zitsulo zowonekera zomwe zidzachotsedwa panthawi ya etching.
Pambuyo pa siteji ya photoresist processing, mapepala azitsulo amasamutsidwa ku makina omwe akutukuka kumene njira ya alkali, yomwe imakhala ndi sodium kapena potaziyamu carbonate, imayikidwa.Njirayi imatsuka filimu yofewa ya photoresist, kusiya mbali zomwe zimayenera kuzikika poyera.
Chotsatira chake, kukana kofewa kumachotsedwa, pamene kukana kolimba, komwe kumafanana ndi madera omwe akuyenera kukhazikitsidwa, kumasiyidwa.Pachitsanzo chotsatira, madera olimba akuwonetsedwa mu buluu, ndipo madera ofewa ndi imvi.Madera omwe sali otetezedwa ndi kutsutsa kolimba amaimira chitsulo chowonekera chomwe chidzachotsedwa panthawi yojambula.
Etching
Mofanana ndi njira yokhomerera asidi, mapepala opangidwawo amaikidwa pa chotengera chomwe chimasuntha mapepalawo kupyolera mu makina omwe amatsanulira momveka bwino pamapepala.Pamene etchant imalumikizana ndi chitsulo chowonekera, imasungunula chitsulo ndikusiya zinthu zotetezedwa.
M'njira zambiri za photochemical, etchant ndi ferric chloride, yomwe imapopera kuchokera pansi ndi pamwamba pa conveyor.Ferric chloride imasankhidwa ngati etchant chifukwa ndiyotetezeka kugwiritsa ntchito komanso kubwezeredwanso.Cupric chloride imagwiritsidwa ntchito popangira mkuwa ndi ma alloys ake.
Njira yopangira etching iyenera kusungidwa bwino nthawi yake ndipo imayendetsedwa molingana ndi chitsulo chomwe chikukhazikika chifukwa zitsulo zina zimatenga nthawi yayitali kuti zikhazikike kuposa zina.Kuti chiwongolero cha photochemical etching chitheke, kuwunika mosamala ndikuwongolera ndikofunikira.
Mu gawo lokhazikika la etching yachitsulo cha photochemical, zitsulo zopangidwa ndi zitsulo zimayikidwa pa conveyor yomwe imawasuntha kupyolera mu makina omwe etchant imatsanuliridwa pa mapepala.Etchant imasungunula zitsulo zowonekera, ndikusiya madera otetezedwa a pepala.
Ferric chloride imagwiritsidwa ntchito nthawi zambiri ngati njira yopangira zithunzi chifukwa ndi yabwino kugwiritsa ntchito ndipo imatha kubwezeretsedwanso.Kwa mkuwa ndi ma alloys ake, cupric chloride imagwiritsidwa ntchito m'malo mwake.
Njira yokhotakhota iyenera kusankhidwa mosamala komanso kuyendetsedwa molingana ndi mtundu wazitsulo zomwe zimakhazikika, chifukwa zitsulo zina zimafunikira nthawi yayitali yokhazikika kuposa zina.Kuti muwonetsetse kuti ntchito ya photochemical etching ikuyenda bwino, kuyang'anira mosamala ndi kuwongolera ndikofunikira.
Kuvula Kanema wa Remaiing Resist
Panthawi yovundukula, chojambula chotsutsa chimagwiritsidwa ntchito pazidutswa kuchotsa filimu yotsalira yotsalira.Kuvula kukamalizidwa, gawo lomaliza limasiyidwa, lomwe likuwoneka pachithunzi pansipa.
Pambuyo pa ndondomeko ya etching, filimu yotsalira yotsutsa pa pepala lachitsulo imachotsedwa pogwiritsira ntchito kutsutsa stripper.Izi zimachotsa filimu yotsalira yotsalira pamwamba pa pepala lachitsulo.
Njira yovula ikatha, gawo lachitsulo lomalizidwa limasiyidwa, lomwe limatha kuwoneka pachithunzi chotsatira.
