Photochemical Metal Etching
Kushandisa Computer Aided Design (CAD)
Iyo process yephotochemical metal etching inotanga nekugadzirwa kwedhizaini uchishandisa CAD kana Adobe Illustrator.Kunyangwe iyo dhizaini iri danho rekutanga mukuita, haisi magumo ekuverenga komputa.Kana kupihwa kwapera, ukobvu hwesimbi hunotarwa pamwe nenhamba yezvidimbu zvichakodzera papepa, chinhu chinodiwa pakudzikisa mutengo wekugadzira.Chikamu chechipiri chehupamhi hwepepa ndeyekugadziriswa kwechikamu chekushivirira, icho chinonamatira pazvikamu zvezvikamu.
Iyo process yephotochemical metal etching inotanga nekugadzira dhizaini uchishandisa CAD kana Adobe Illustrator.Nekudaro, iyi handiyo yega kuverenga komputa inobatanidzwa.Mushure mekupedza dhizaini, kukora kwesimbi kunotarwa, pamwe nenhamba yezvimedu zvinogona kukwana pane pepa kuderedza mari yekugadzira.Pamusoro pezvo, kushivirira kwechikamu kunoenderana nechikamu chezvikamu, izvo zvakare zvinokonzeresa mukukora kwepepa.
Kugadzirira Kwesimbi
Sezvakaita acid etching, simbi inofanirwa kunyatsocheneswa isati yagadziriswa.Chidimbu chega chega chesimbi chinokweshwa, kucheneswa, uye kucheneswa pachishandiswa mvura uye munyungudutsa munyoro.Iyo nzira inobvisa oiri, zvinosvibisa, uye diki diki.Izvi zvinodikanwa kuti upe yakatsetseka yakachena nzvimbo yekushandiswa kweiyo photoresist firimu kuti inamate zvakachengeteka.
Laminating Metal Sheets ane Photoresistant Mafirimu
Lamination ndiko kushandiswa kweiyo photoresist firimu.Mashizha esimbi anofambiswa pakati pema rollers anopfeka uye akaenzana shandisa lamination.Kuti udzivise kuratidzwa zvisina kufanira kwemashiti, maitiro anopedzwa mukamuri yakavhenekerwa nemwenje yeyero kudzivirira kubuda kweUV mwenje.Kurongeka kwakakodzera kwemashizha kunopiwa nemakomba akaroverwa mumicheto yemashizha.Mabhubhu ari mumucheka wakavezwa anodzivirirwa nevhavha yekuisa chisimbiso mashizha, iyo inogadzirisa zvidimbu zvelaminate.
Kugadzirira simbi ye photochemical metal etching, inofanira kunyatsocheneswa kubvisa mafuta, zvinosvibisa, uye zvidimbu.Chidimbu chega chega chesimbi chinokweshwa, kucheneswa, uye kugezwa nemhepo yakapfava uye kudzvanywa kwemvura kuti ive nechokwadi chenzvimbo yakatsetseka, yakachena yekushandiswa kwefirimu rephotoresist.
Nhanho inotevera ndeye lamination, iyo inosanganisira kuisa iyo photoresist firimu kumashizha esimbi.Mashizha anofambiswa pakati pema rollers kuti apfeke zvakaenzana uye aise iyo firimu.Maitiro acho anoitwa mune yero-lit kamuri kudzivirira UV mwenje kuratidzwa.Makomba akabayiwa mumicheto yemashizha anopa kurongeka kwakakodzera, nepo vacuum sealing inodzikamisa zvidimbu zvelaminate uye inodzivirira mabhubhu kuumbwa.
Photoresist Processing
Munguva yekugadziriswa kwephotoresist, mifananidzo kubva kuCAD kana Adobe Illustrator rendering inoiswa pachikamu chephotoresist papepa resimbi.Iyo CAD kana Adobe Illustrator rendering inodhindwa pamativi ese esimbi pepa nekuaisa sandwich pamusoro nepasi pesimbi.Kana mapepa esimbi aine mifananidzo yaiswa, anoiswa pachena kune UV mwenje inoisa iyo mifananidzo zvachose.Ikoko mwenje weUV unopenya kuburikidza nenzvimbo dzakajeka dzelaminate, iyo photoresist inova yakasimba uye inoomesa.Nzvimbo nhema dzelaminate dzinoramba dzakapfava uye dzisina kufurirwa nemwenje weUV.
Mune photoresist yekugadzirisa nhanho yephotochemical simbi etching, iyo mifananidzo kubva kuCAD kana Adobe Illustrator dhizaini inotamirwa pane layer yephotoresist pashizha resimbi.Izvi zvinoitwa ne sandwiching dhizaini pamusoro uye pasi pesimbi pepa.Kana iyo mifananidzo ichinge yaiswa kune simbi pepa, inoburitswa kune UV mwenje, izvo zvinoita kuti mifananidzo igare.
Munguva yekuratidzwa kweUV, nzvimbo dzakajeka dzelaminate dzinobvumira mwenje weUV kuti upfuure, zvichiita kuti photoresist iome uye isimbe.Kusiyana neizvi, nzvimbo nhema dzelaminate dzinoramba dzakapfava uye dzisina kukanganiswa nechiedza cheUV.Iyi nzira inogadzira maitiro anozotungamira etching process, uko nzvimbo dzakaomeswa dzicharamba dziripo uye nzvimbo dzakapfava dzichaiswa kure.
Kugadzira Mapepa
Kubva pakugadziriswa kwephotoresist, mapepa anoenda kumuchina unogadzira unoshandisa alkali solution, kunyanya sodium kana potassium carbonate solution, inosuka firimu rakapfava refotoresist richisiya zvikamu zvichiiswa pachena.Iyo nzira inobvisa iyo yakapfava kuramba uye inosiya yakaomeswa inopikisa, inova chikamu chinofanira kuiswa.Mumufananidzo uri pasi apa, nzvimbo dzakaoma dziri mubhuruu, uye nzvimbo dzakapfava dzine grey.Nzvimbo dzisina kuchengetedzwa neakaomeswa laminate isimbi yakafumurwa inozobviswa panguva yekucheka.
Mushure meiyo photoresist yekugadziridza nhanho, mapepa esimbi anobva aendeswa kumushini unogadzira uko kunoiswa alkali solution, kazhinji sodium kana potassium carbonate.Iyi mhinduro inosuka iyo yakapfava photoresist firimu, ichisiya zvikamu zvinoda kuvharirwa pachena.
Somugumisiro, kupikisa kwakapfava kunobviswa, nepo kurwisana kwakaoma, kunofananidzwa nenzvimbo dzinoda kuiswa, inosara shure.Muchigumisiro chinoguma, nzvimbo dzakaoma dzinoratidzwa mubhuruu, uye nzvimbo dzakapfava dzine grey.Nzvimbo dzisina kudzivirirwa neyakaomeswa inopikisa inomiririra simbi yakafumurwa iyo ichabviswa panguva ye etching process.
Etching
Zvakawanda senge acid etching process, mapepa akagadzirwa anoiswa pane conveyor inofambisa mapepa nemuchina unodurura etchant pamapepa.Panosangana etchant nesimbi iri pachena, inonyungudutsa simbi ichisiya zvinhu zvakachengetedzwa.
Mune akawanda photochemical process, iyo etchant ndeye ferric chloride, iyo inopfapfaidzwa kubva pasi nepamusoro pemutakuri.Ferric chloride inosarudzwa seyakanaka nekuti yakachengeteka kushandisa uye kudzokororwa.Cupric chloride inoshandiswa kutema mhangura uye alloys ayo.
Iyo etching process inofanirwa kuverengerwa nguva uye inodzorwa zvinoenderana nesimbi iri kuroverwa sezvo mamwe masimbi anotora nguva yakareba kuti atore kupfuura mamwe.Kuti ibudirire yephotochemical etching, kunyatsotarisisa uye kutonga kwakakosha.
Muchikamu chekumisikidza chephotochemical metal etching, mashizha esimbi akagadzirwa anoiswa pane inotakura inoafambisa nemuchina unodirwa etchant pamapepa.Iyo etchant inonyungudutsa simbi yakazaruka, ichisiya kumashure kwenzvimbo dzakachengetedzwa dzepepa.
Ferric chloride inowanzoshandiswa seyakajeka mune yakawanda photochemical process nekuti yakachengeteka kushandisa uye inogona kudzokororwa.Kune mhangura uye alloys ayo, cupric chloride inoshandiswa panzvimbo.
Iyo etching maitiro anofanirwa kuverengerwa nguva uye kudzorwa zvinoenderana nerudzi rwesimbi irikumisikidzwa, sezvo mamwe masimbi anoda nguva yakareba etching kupfuura mamwe.Kuti uve nechokwadi chekubudirira kweiyo photochemical etching process, kunyatsotarisisa uye kutonga kwakakosha.
Kukurura Rasara Resist Firimu
Munguva yekubvisa, chigadziro chinopikisa chinoshandiswa kune zvimedu kuti chibvise chero firimu rinoramba rasara.Kana kubviswa kwapera, chikamu chakapedzwa chasara, chinogona kuonekwa mumufananidzo uri pasi apa.
Mushure mekuita etching, iyo yakasara inopikisa firimu pane simbi pepa inobviswa nekuisa resista stripper.Iyi nzira inobvisa chero yakasara inopikisa firimu kubva pamusoro pesimbi sheet.
Kana imwe nzira yekubvisa yapera, chikamu chesimbi chakapedzwa chinosara, chinogona kuonekwa mumufananidzo unoguma.
