Photochemical Hlau Etching
Siv Computer Aided Design (CAD)
Cov txheej txheem ntawm photochemical hlau etching pib nrog kev tsim cov qauv siv CAD lossis Adobe Illustrator.Txawm hais tias tus qauv tsim yog thawj kauj ruam hauv cov txheej txheem, nws tsis yog qhov kawg ntawm kev suav hauv computer.Thaum lub rendering tiav lawm, lub thickness ntawm cov hlau yog txiav txim raws li tus naj npawb ntawm daim ntawv uas yuav haum rau ib daim ntawv, ib tug tsim nyog yuav tsum tau txo tus nqi ntawm ntau lawm.Ib qho thib ob ntawm lub thickness ntawm daim ntawv yog kev txiav txim siab ntawm ib feem tolerances, uas pob khawm ntawm qhov ntev.
Cov txheej txheem ntawm photochemical hlau etching pib nrog kev tsim qauv siv CAD lossis Adobe Illustrator.Txawm li cas los xij, qhov no tsis yog tib qho kev suav hauv computer nkaus xwb.Tom qab ua tiav qhov kev tsim, lub thickness ntawm cov hlau yog txiav txim siab, nrog rau cov naj npawb ntawm cov khoom uas tuaj yeem haum rau ntawm daim ntawv kom txo tau cov nqi tsim khoom.Tsis tas li ntawd, qhov kev tolerances nyob ntawm seb qhov ntev ntawm qhov ntev, uas tseem cuam tshuam rau cov thickness ntawm daim ntawv.
Kev npaj hlau
Raws li nrog acid etching, cov hlau yuav tsum tau muab ntxuav kom huv si ua ntej ua tiav.Txhua daim hlau yog txhuam, ntxuav, thiab ntxuav nrog dej siab thiab cov kuab tshuaj me me.Cov txheej txheem tshem tawm cov roj, cov khoom paug, thiab cov khoom me me.Qhov no yog tsim nyog los muab ib tug du du nto rau daim ntawv thov ntawm photoresist zaj duab xis kom securely adhere.
Laminating Hlau Sheets nrog Photoresistant Films
Lamination yog daim ntawv thov ntawm cov yeeb yaj kiab photoresist.Cov ntawv hlau yog txav nruab nrab ntawm cov chais uas lub tsho tiv no thiab sib npaug ntawm cov lamination.Txhawm rau kom tsis txhob muaj qhov cuam tshuam tsis zoo ntawm cov nplooj ntawv, cov txheej txheem ua tiav hauv chav teeb nrog lub teeb daj kom tiv thaiv UV teeb pom kev.Kev sib raug zoo ntawm cov nplooj ntawv yog muab los ntawm qhov punched nyob rau hauv cov npoo ntawm nplooj ntawv.Cov npuas nyob rau hauv lub laminated txheej yog tiv thaiv los ntawm lub tshuab nqus tsev sealing cov nplooj ntawv, uas flattens cov txheej ntawm laminate.
Txhawm rau npaj cov hlau rau photochemical hlau etching, nws yuav tsum tau ntxuav kom huv si kom tshem tawm cov roj, cov kab mob, thiab cov khoom.Txhua daim hlau yog txhuam, ntxuav, thiab ntxuav nrog cov kuab tshuaj me me thiab cov dej siab kom ua kom lub ntsej muag du, huv si rau daim ntawv thov ntawm cov yeeb yaj kiab photoresist.
Cov kauj ruam tom ntej yog lamination, uas suav nrog kev siv cov yeeb yaj kiab photoresist rau cov ntawv hlau.Cov nplooj ntawv yog txav ntawm cov chais mus rau lub tsho sib npaug thiab siv cov yeeb yaj kiab.Cov txheej txheem yog ua nyob rau hauv ib tug daj-lit chav tsev los tiv thaiv UV teeb raug.Qhov punched nyob rau hauv cov npoo ntawm cov nplooj ntawv muab kev sib raug zoo, thaum lub tshuab nqus tsev sealing flattens cov txheej ntawm laminate thiab tiv thaiv npuas los ntawm kev sib sau.
Photoresist processing
Thaum lub sij hawm ua photoresist, cov duab los ntawm CAD lossis Adobe Illustrator rendering yog muab tso rau ntawm txheej ntawm photoresist ntawm cov ntawv hlau.CAD los yog Adobe Illustrator rendering yog imprinted rau ob sab ntawm daim hlau los ntawm sandwiching lawv tshaj thiab nyob rau hauv cov hlau.Thaum cov ntawv hlau muaj cov duab thov, lawv raug UV teeb uas tso cov duab mus tas li.Qhov twg UV teeb ci los ntawm qhov chaw ntshiab ntawm lub laminate, lub photoresist yuav khov thiab tawv.Cov cheeb tsam dub ntawm lub laminate tseem mos thiab tsis cuam tshuam los ntawm UV teeb.
Nyob rau hauv cov txheej txheem photoresist ntawm photochemical hlau etching, cov duab los ntawm CAD lossis Adobe Illustrator tsim raug xa mus rau txheej ntawm photoresist ntawm cov ntawv hlau.Qhov no yog ua los ntawm sandwiching tus tsim tshaj thiab nyob rau hauv cov hlau ntawv.Thaum cov duab raug siv rau cov ntawv hlau, nws raug UV teeb, uas ua rau cov duab mus tas li.
Thaum lub sij hawm raug UV, qhov chaw ntshiab ntawm lub laminate tso cai rau UV teeb hla dhau, ua rau cov photoresist harden thiab ruaj khov.Hauv qhov sib piv, cov cheeb tsam dub ntawm lub laminate tseem mos thiab tsis cuam tshuam los ntawm UV teeb.Cov txheej txheem no tsim cov qauv uas yuav coj cov txheej txheem etching, qhov chaw hardened yuav nyob twj ywm thiab cov chaw mos yuav etched tam sim ntawd.
Txhim kho cov ntawv
Los ntawm kev ua cov txheej txheem photoresist, cov nplooj ntawv txav mus rau lub tshuab tsim tawm uas siv cov tshuaj alkali, feem ntau yog sodium los yog potassium carbonate cov ntsiab lus, uas ntxuav tawm cov mos photoresist zaj duab xis tawm hauv qhov chaw kom raug etched.Cov txheej txheem tshem tawm qhov muag muag thiab tawm ntawm qhov tawv tawv, uas yog qhov yuav tsum tau etched.Hauv cov duab hauv qab no, cov chaw tawv tawv yog xim xiav, thiab cov chaw mos yog grey.Cov chaw uas tsis muaj kev tiv thaiv los ntawm hardened laminate yog raug hlau uas yuav raug tshem tawm thaum lub sij hawm etching.
Tom qab cov txheej txheem photoresist, cov nplooj ntawv hlau raug xa mus rau lub tshuab tsim qhov twg cov tshuaj alkali, feem ntau yog siv sodium los yog potassium carbonate.Qhov kev daws teeb meem no tshem tawm cov duab mos photoresist, tawm hauv qhov chaw uas yuav tsum tau etched raug.
Yog li ntawd, qhov muag muag raug tshem tawm, thaum lub hardened resist, uas sib haum mus rau qhov chaw uas yuav tsum tau etched, yog sab laug.Nyob rau hauv cov qauv tshwm sim, cov cheeb tsam hardened yog pom nyob rau hauv xiav, thiab cov chaw mos yog grey.Cov cheeb tsam uas tsis muaj kev tiv thaiv los ntawm hardened tiv taus sawv cev rau cov hlau raug tshem tawm thaum lub sij hawm etching txheej txheem.
Etching
Zoo li cov txheej txheem acid etching, cov nplooj ntawv tsim tau muab tso rau ntawm cov khoom siv uas txav cov nplooj ntawv los ntawm lub tshuab uas nchuav etchant ntawm cov nplooj ntawv.Qhov twg cov etchant txuas nrog cov hlau raug, nws dissolves cov hlau tawm hauv cov khoom tiv thaiv.
Nyob rau hauv feem ntau cov txheej txheem photochemical, etchant yog ferric chloride, uas yog txau los ntawm hauv qab thiab sab saum toj ntawm lub conveyor.Ferric chloride raug xaiv los ua etchant vim nws muaj kev nyab xeeb siv thiab rov ua dua tshiab.Cupric chloride yog siv los etch tooj liab thiab nws cov alloys.
Cov txheej txheem etching yuav tsum tau ua tib zoo sijhawm thiab tswj tau raws li cov hlau uas tau etched vim qee cov hlau siv sijhawm ntev dua rau etch dua lwm tus.Rau kev vam meej ntawm photochemical etching, ceev faj saib xyuas thiab tswj yog qhov tseem ceeb heev.
Nyob rau hauv lub etching theem ntawm photochemical hlau etching, cov ntaub ntawv tsim tau muab tso rau ntawm ib tug conveyor uas txav lawv los ntawm lub tshuab uas etchant yog poured rau hauv daim ntawv.Lub etchant dissolves cov hlau raug, tawm hauv qab qhov chaw tiv thaiv ntawm daim ntawv.
Ferric chloride feem ntau yog siv los ua ib qho etchant hauv feem ntau cov txheej txheem photochemical vim nws muaj kev nyab xeeb siv thiab tuaj yeem rov ua dua.Rau tooj liab thiab nws cov alloys, cupric chloride yog siv xwb.
Cov txheej txheem etching yuav tsum tau ua tib zoo sijhawm thiab tswj raws li hom hlau raug etched, vim qee cov hlau yuav tsum tau etching ntev dua li lwm tus.Txhawm rau kom ua tiav cov txheej txheem photochemical etching, ua tib zoo saib xyuas thiab tswj yog qhov tseem ceeb.
Stripping Cov Yeeb Yam Tseem Ceeb
Thaum lub sij hawm stripping txheej txheem, ib tug resist stripper yog siv rau tej daim kom tshem tawm cov seem uas tsis muaj zaj duab xis.Thaum stripping tiav lawm, qhov tiav lawm sab laug, uas tuaj yeem pom hauv daim duab hauv qab no.
Tom qab cov txheej txheem etching, qhov seem tiv thaiv zaj duab xis ntawm cov ntawv hlau raug muab tshem tawm los ntawm kev siv tus tiv thaiv stripper.Cov txheej txheem no tshem tawm cov yeeb yaj kiab uas tseem tshuav los ntawm qhov chaw ntawm cov ntawv hlau.
Thaum cov txheej txheem stripping tiav, cov hlau tiav lawm sab laug, uas tuaj yeem pom hauv cov duab tshwm sim.
