Ua ntej peb pib tham nrog koj li cas los tswj cov ntiv taw xoom, peb yuav tsum xub saib cov teeb meem uas peb tau pom hauv kev luam tawm yav dhau los: 1. Cov xim ntawm cov luam tawv xim yog sib sib zog nqus thiab ntiav. 2. Thaum lub vas raug kho, qhov teeb meem loj dua (muaj qhov tshwm sim zoo). 3. Qhov txawv ntawm xim thaum lub sij hawm luam ntawv. Cov teeb meem no yuav cuam tshuam rau cov sij hawm tsim thiab cov khoom rov qab, uas yuav coj tsis zoo rau qhov normalization ntawm peb txoj haujlwm. Yuav ua li cas los tswj thiab tiv thaiv cov teeb meem no yog tsim nyog ntawm kev sib tham los ntawm peb cov neeg ua haujlwm luam ntawv. Cov nram qab no yog cov uas peb yuav tsum to taub hauv kev luam ntawv.
Ua ntej, tshawb xyuas tus lej ntawm theoretical amount:
Nws muaj ob txoj kev los ntsuam xyuas tus nqi ntawm cov cwj mem ntawm qhov screen. Ib tug yog los laij cov cim theoretical permeability ntawm qhov screen, thiab lwm tus yog ua tau sau tus nqi ntawm tus number case. Xam theem number of theoretical uas muaj cov formula nram qab no:
Qhib piv: L
Lub thickness ntawm qhov screen yog: D
Theoretical number case penetration yog: M = L × D ÷ 100%
Cov qauv saum toj no tsuas yog ib qho qauv theoretical rau xam tus nqi ntawm cov cwj mem ntawm qhov screen. Thaum ua ntawv thov luam ntawv, cov ntaub ntawv yuav hloov, tab sis nws yog proportional. Cia peb saib cov nram qab no:
1. Mesh tus xov tooj ntawm cov hlau mesh (ncaj qha txiav txim siab rau lub qhov dav thiab qhov qhib qhov qhib). Qhov siab dua qhov mesh loj, qhov me me qhov qhov dav, thiab qhov tsawg dua qhov qhib piv. Piv txwv, 355 mesh npo muaj lub qhov dav ntawm 31 μm, qhib qhov ntawm 26%, thiab ib daim duab theoretical permeability ntawm 14.3 cm 3 / m 2. Lub 305 mesh screen muaj lub qhov dav ntawm 45 μm thiab ib qho qhib lub cell ntawm 35%. Theoretical number case permeability yog 16.3 cm 3 / m 2.
2. Cov kab hlau ntawm lub xaim hlau (ncaj qha cuam tshuam lub mesh thickness, qhib piv, mesh loj). Nws yog hais txog lub taub ntawm lub xaim uas tsis xaim, thiab txoj kab uas hla caws tom qab nws pauv ua elliptical. Yuav cuam tshuam qhov loj ntawm lub mesh. Tib qhov mesh loj ntawm lub mesh yuav cuam tshuam qhov qhib loj thiab qhib qhov sawv.
Piv txwv, 305 mesh hlau diameter 31um qhib piv yog 35%, qhov dav qhov yog 49um, mesh thickness yog 49um, thiab tus lej theoretical permeability yog 17.2cm3 / m2.
305 mesh wire diameter 34um qhib piv yog 29.6%, lub qhov dav yog 45um, mesh thickness yog 55um, thiab tus kab kos theoretical permeability yog 16.3cm3 / m2.
Lub 305 mesh hlau diam 40um qhib qhov qhib yog 20.1%, lub qhov dav yog 37um, thiab lub mesh thickness yog 65um. Theoretical number case permeability yog 13cm3 / m2.
3. Lub thickness ntawm qhov screen (ncaj qha rau cuam tshuam tus number case txheej). Peb tuaj yeem siv lub ntsuas tuab tuab los ntsuas qhov thickness ntawm qhov screen. Vim tias cov ntxaij los ntawm ntau lub tuam txhab ua tau rau lawv tus kheej cov txheej txheem, qhov warp thiab lub nraub nyuj threads tsis khoov rau tib qhov kawg. Qhov ntau dua qhov kev ncua ntawm kev khoov, tus thinner qhov screen yuav ua, thiab vice versa. Thaum lub sij hawm ncab ce, cov xaim hluav taws xob ncav yog ncab vim muaj tus cwj pwm ntawm sab nraud quab yuam, uas nws thiaj li yuav cuam tshuam rau cov tuab ntawm cov hlau xaim.
4. Lub qhov dav ntawm lub vijtsam (ncaj qha raug rau tus number case number). Peb paub tias qhov dav dav hauv lub mesh, loj dua tus nqi ntawm tus cwj mem. Nyob rau hauv tus txheej txheem ntawm ncab lub net, lub siab dua lub nro, txo qhov mesh loj, thiab wider lub Mesh, loj dua tus nqi ntawm number case permeated.
5. Lub sij hawm qhib qhov screen (ncaj qha raug rau tus number case number). Qhov qhib lub xov tooj ntawm tes piv rau qhov dawb piv ntawm thaj chaw ntawm tus number case ntawm txhua cheeb tsam ntawm qhov screen rau tag nrho cheeb tsam. Piv txwv, rau ib qho screen uas qhib qhov qhib ntawm 35%, feem ntawm tus lej feem khaus uas yog 35%, thiab qhov feem uas tsis yog permeable rau qhov screen yog 65%. Qhov ntau dua qhov qhib qhov sib txawv, qhov loj dua tus nqi ntawm tus number case discharged.
Lossis xam mis:
Qhov dav dav yog: K
Cov meshes yog: M
Ntiag yog: Y
Qhib piv: L = K × M ÷ Y2 × 100%
6. Lub dav hlau siab ntawm cov hlau mesh (ncaj qha cuam tshuam lub mesh thickness, qhov dav).
Ntau tshaj 355 mesh ntawm cov tho txawv teb mesh yog siv rau kev sib zog. Lub screen flattened obviously ua thinner thiab cov mesh yuav ua me dua. Thaum twg cov kab xaim mesh ncav lawm, cia peb saib cov piv txwv nram qab no: 10% ~ 15% naj npawb tau txuag tau thaum lub dav hlau nias ntawm lub plhom sab, thiab 15% ntawm tus cwj pwm yuav raug dim los ntawm kev ncab nias mus rau qhov chaw luam tawm. ~ 25%.
Thib ob, tus nqi tiag tiag ntawm tus cwj pwm luam tawm:
1. Lub nro ntawm qhov screen (cuam tshuam qhov loj ntawm lub qhib, mesh loj, xaim diameter, mesh thickness). Thaum lub sij hawm ua kom ncab tus naj npawb, raws li qhov nruj nce, qhov kev tsis ntawm qhov kev tshuaj ntsuam nws tus kheej yuav hloov raws li. Ua ntej, nws cuam tshuam lub mesh tus xov tooj ntawm lub Mesh. Qhov siab dua qhov nro, qhov loj dua cov mesh suav (txog thaum lub mesh yog plastically deformed). Tom ntej no, nws yuav cuam tshuam qhov qhov dav ntawm lub vijtsev, lub mesh yuav dhau los, cov kab hlau yuav thim, thiab cov mesh yuav ua thinner. Cov xwm txheej no yuav tshwm sim los ua rau muaj kev hloov ntawm tus number case.
2. Lub thickness ntawm zaj duab xis txheej (txiav txim seb tus nqi ntawm tus number case). Yog tias peb siv cov duab ci ntsa iab los ua qhov screen, peb kuj yuav tsum xav txog cov ntsiab lus ntawm photoresist nws tus kheej. Tom qab lub phaj raug nias, zaj duab xis yuav yaj thiab zaj duab xis yuav ua thinner. Yog li, peb tsuas siv tau tuab tuab tuab kom pom lub ntsiab lus ntawm qhov npo.
3. Ink ntaus (khawm cuam tshuam lub thickness ntawm tus number case txheej). Peb paub tias tom qab tus cwj mem xees luam tawm, cov tshuaj hnyav yuav vau thiab lub plhaub ntim quav yuav pib thia. Tom qab lub teeb uas muaj lub plhaub tawm, muab cov ntaub ntawv rov qab los ua kom tiav tom qab raug irradiated nrog ultraviolet rays, yog li cov ink txheej plua tshauv unchanged.
4. Lub xauv npo ntawm tus cwj pwm (txav mus rau lub thickness ntawm tus number case txheej). Qhov txo tus viscosity ntawm tus number case, lub thicker tus number case yuav yuav nyob rau hauv cov txheej txheem luam ntawv vim hais tias tus number case nws tus kheej muaj tsawg hnyav thiab, ntawm qhov tsis tooj, thinner.
5. Lub hardness ntawm squeegee (indirectly cuam tshuam lub thickness ntawm tus number case txheej). Nyob rau hauv cov txheej txheem luam ntawv, qhov ntau dua qhov nyuaj ntawm tus cwj pwm, qhov tsawg dua nws yog deform, thiab tus nqi tsawg dua ntawm tus cwj pwm, qhov loj tshaj qhov ntxeev lus.
6. Lub qhov ncauj ntawm caj dab (ncaj qha raug rau tus number case number). Yog hais tias ntug ntawm khawb ntawm ib txoj kab, qhov nyiaj ntawm tus lej yog me me. Yog tias tus number case yog nyob ntawm obtus kaum, tus nqi ntawm tus lej yog loj.
7. Lub kaum sab xis ntawm scraper. (Indirectly cuam tshuam lub thickness ntawm tus number case txheej). Thaum lub sij hawm luam ntawv, lub me me ntawm cov hniav thiab qhov screen, qhov loj ntawm tus lej number case, vim hais tias cov hniav yog nyob rau ntawm qhov chaw ze ntawm qhov screen. Cov lus rov qab yog me me.
8. Lub siab ntawm scraper (ncaj qha raug rau tus number case number). Thaum lub sij hawm luam tawm, qhov ntau dua qhov siab siv rau ntawm lub ntsej muag, qhov tsawg dua tus cwj mem yog, vim hais tias tus number case twb tau rushed ua ntej nws yuav nkag mus hauv lub mesh tag. Cov lus rov qab yog me me.
9. Lub siab ntawm tus cwj mem rov los xo pob (khov khiab ncaj qha). Qhov ntau dua qhov muaj qhov nyhav rau lub cwj mem, qhov ntau dua tus lej ntawm qhov uas muaj tsawg tus number case ntawm lub ciab ntawm lub ciab ntawm tus cwj pwm ua ntej nws yog smeared. Cov lus rov qab yog me me.
10. Cov kev ceev ceev ntawm cov tsheb ciav hlau (kheev cuam tshuam lub thickness ntawm tus number case txheej). Kev ceev ceev, qhov me dua ntawm cov ntawv number case, vim hais tias tus number case twb tsis tau lawm, thiab tus number case twb tau squeezed tawm, ua rau tus number case los yuav tu ncua.
11. Cov ntawv luam tawm. (Ncaj nraim rau lub thickness ntawm tus number case txheej). Lub flatness ntawm lub npoo ntawm lub substrate kuj cuam tshuam lub thickness ntawm tus number case txheej, thiab tus dav ntim dej naj npawb yuav nkag mus (xws li ntaub npuag, tawv, ntoo). Qhov txawv yog loj.
12. Luam ntawv cheeb tsam (tshwj xeeb tshaj yog cuam tshuam lub thickness ntawm tus number case txheej). Ib qho teeb meem uas peb niaj zaus toob pub yog qhov hloov hauv qhov kub thiab txias ntawm qhov chaw luam ntawv. Yog tias qhov kub ntawm qhov chaw luam ntawv hloov ntau dhau lawm, nws yuav cuam tshuam tus lej ntawm nws tus kheej (xws li ink viscosity, fluidity, etc.).
Peb, yuav ua li cas los xam cov thickness ntawm tus number case txheej?
Los ntawm cov kev sib tham saum toj no, peb paub tias yog muaj qee qhov txuas hloov thaum txheej txheem luam ntawv, thiab qhov kawg ntawm tus cwj mem yog inconsistent, ua li cas peb yuav xam cov thickness ntawm cov ink txheej? Ib txoj kev yog ntsuas phaus ntawm tus cwj pwm ntub dej. Ua ntej, sim tswj txhua qhov txuas rau hauv kev luam ntawv kom nyob twj ywm tsis hloov. Tom qab luam ntawv, qhov nyhav rau ntawm cov ntawv sau tawm, thiab tom qab ntawd ces thawj qhov hnyav ntawm lub substrate raug rho tawm. Cov ntaub ntawv tau muab yog ntub dej ciav hlau. Qhov hnyav, lwm txoj yog cov thickness ntawm tus number case-xab txheej. Lub thickness ntawm lub substrate tom qab over-inking yog ntsuas los ntawm thickness gauge, thiab cov thawj thickness ntawm cov substrate yog rho, thiab cov ntaub ntawv tau muab cov thickness ntawm tus number case txheej.
Plaub, yuav ua li cas tswj cov thickness ntawm tus number case txheej?
Yuav ua li cas los tswj cov thickness ntawm tus number case txheej tau ua ib qho teeb meem ntsib los ntawm kev tshuaj ntsuam luam ntawv neeg ua hauj lwm. Ua ntej tshaj plaws, peb yuav tsum siv cov khoom ntsuas uas twb muaj lawm los xyuas kom meej tias qhov tseeb thiab qhov tseeb ntawm cov ntaub ntawv ntsuas; lub Hoobkas siv tau cov kev mob uas tsis yog siv.
