Lub teb chaws suav screen printing yog nyob rau hauv ib lub sij hawm ntawm kev loj hlob sai, yuav ua li cas luam tau zoo nkauj thiab tseeb sau, raws li kev lag luam yog lub hom phiaj ntawm txhua lub tuam txhab. Tam sim no, ntau lub lag luam me me thiab nruab nrab tseem ua raws li kev siv tes ua kev sib tw raws li kev paub thiab kev sim tes, uas ua rau kev txhim kho ntawm kev luam ntawv zoo. Yuav ua li cas paub lub dataization thiab standardization ntawm kev tshuaj ntsuam luam tawm yog ib qho teeb meem ntsib los ntawm txhua lub tuam txhab. Daim ntawv thov cov cuab yeej siv rau kev luam ntawv yog tus yuam sij rau kev daws qhov teeb meem no. Ntawm no yog ob peb yam ntawm cov khoom siv los ntawm kev siv luam ntawv.
Mesh xeem thooj
Mesh test piece yog ib qho ntawm cov cuab yeej xeem uas feem ntau siv los ntawm cov tshuab luam ntawv. Nws yog ntsuas cov mesh suav ntawm lub screen xaiv. Qhov kev pab yog muab xa cov mesh xeem daim vij rau lub vijtsam, thiab saib lub teeb thiab tig rau qhov kev xeem mesh. Qhov no yog kom pom cov pob zeb diamondged zoo li ntawm lub ntsej muag. Qhov kev nyeem ntawv tau qhia los ntawm lub kaum pob zeb loj thiab qis ntawm pob zeb diamond yog lo lus. Tus nab npawb ntawm meshes. Daim ntawv thov ntawm cov ntawv xeem mesh plays lub luag haujlwm tseem ceeb hauv qhov kev xaiv kom yog thiab yuav ntawm qhov screen. Nyob rau tib lub sijhawm, nws tuaj yeem ntsuas cov naj npawb ntawm cov ntawv ntsuam xyuas rau cov khoom kuaj mob kuaj xyuas. Tus qauv ntawm kev siv yog tib yam li saum toj no.
Sib tw kev xeem
Raug xeem cov strips yog ib qho ntawm kev siv ntau qhov kev xeem rau cov tshuab luam ntawv. Nws tuaj yeem kuaj qhov tseeb raug lub sijhawm ntawm ntau hom duab ci ntsa iab, ntau lub teeb ci, txawv xim cov ntxaij vab tshaus, thiab txawv cov xim tha xim duab. Raug xeem cov strips feem ntau muaj tsib gray ntom kuaj xeem ntu, txhua qhov nrog rau qhov raug, feem ntau 1, 0.7, 0.5, 0.35, 0.25. Tom qab luam ntawv, saib kab lus txhais ntawm tsib gray gradients ntawm qhov kev tshuaj ntsuam, thiab muab cov sij hawm ntau tshaj plaws los ntawm qhov tseeb tshaj plaws los ntawm lub sij hawm raug lub sij hawm los xam lub sij hawm raug. Piv txwv, lub sij hawm luam yog 10min, thiab txoj kab ntawm 0.7 theem tom qab luam ntawv yog qhov tseeb, uas yog, 7min tau nrog 10minX0.7 yog lub sij hawm zoo tshaj plaws ntawm qhov kev tshuaj ntsuam no. Nyob rau tib lub sij hawm, qhov kev sib tw raug feem ntau kuj muaj kev ntsuam xyuas nrog dot test ntawm 1% mus rau 97% txawv cov laus. Qhov kev sib tw kis tau yog qhov tseem ceeb hauv kev txhim kho cov phaj qoob loo.
Kev soj ntsuam daim ntawv xeem
Daim qauv kev sib tw yog ib qho ntawm cov cuabyeej kev xeem rau cov phaj ua cov txheej txheem. Nws tuaj yeem kuaj qhov kev daws teeb meem ntawm photoresist siv. Daim xeem thooj ntawv sau txog 15 gradient kab los ntawm 0.025 mus rau 0.375 mm thiab yim gradients ntawm 0.5 mus rau 4 hli. Tshawb xyuas cov kab thiab cov dots ntawm lub vijtsam uas tau tshwm sim ntawm lub sijhawm zoo los tshuaj xyuas qhov kev daws teeb meem ntawm photoresist uas koj siv. Nyob rau tib lub sijhawm, nws tuaj yeem cuam tshuam cov teeb meem ntawm cov kab ntawm ntau cov ces kaum ntawm qhov screen.
Voj npauj lub voj voog
Kev ntsuam xyuas lub vev xaij yog ib qho cuab yeej tshwj xeeb rau kev ntsuam xyuas lub kaum ntsej muag kuaj lub sij hawm thaum kuaj xyuas. Nws tuaj yeem ntsuas kev ntsuam xyuas lub kaum plaub ntawm plaub qhov tsis zoo nkauj ntawm daj, xim dub, xim dub thiab dub los yog monochrome npo luam ntawv hauv monochrome kuaj thiab plaub kuaj xim. Tus qauv ntawm kev siv yog muab cov ntawv xeem rau qhov tsis zoo zaj duab xis los yog cov kab sau ua ke, thiab tig txoj kev xeem. Lub sijhawm no, nws yuav pom tau tias kev xeem daim tawm ua ib qho kev sib tshuam los yog lub pob zeb diamonds, thiab lub kaum sab xis ntawm qhov chaw ntawm qhov kev cuam tshuam kev cuam tshuam yog lub kaum sab xis ntawm lub vijtsam.
Tonometer
Tensiometers yog ib qho cuab yeej hauv cov txheej txheem ntawm kev luam ntawv. Tam sim no, feem ntau siv siv nro gauges hauv Suav teb tau muab faib rau Newton Tensiometer (N / cm) thiab millimeter Tensiometer. Lawv txhua tus siv qhov kev nyhav nyhav rau tus kheej kom ntsuas txoj kev nruj nruj. Newton Tensiometer tau ncaj qha nyeem cov nqi nro. Thaum ncab lub vas, qhov nro yuav muaj feem ntau ntawm 8 thiab 25 N / cm raws li qhov yuav tsum tau muaj cov kev luam tawm txawv. Lub ntsuas 'meter ntawm tus millimeter tensiometer yog ib qho kev qhia hu. Thaum siv nws, lub tensiometer yuav tsum tau muab tso rau ntawm daim iav siv thiab lub koob yuav tsum tau zeroed, ces muab tso rau ntawm lub thawv stretched mesh. Loj tes tig rov qab mus rau sab nraud, thiab lub me me thawb xoob moos. Qhov nyuaj nro yog tau los ntawm kev nyeem rov qab nyeem ntawv. Lub nrawm ntawm lub vas stretch muaj feem xyuam rau cov sau npe thiab luam ua kom ntev ntawm cov luam tawm hauv kev luam ntawv.
Lub ntsuas phom
Cov xim thaij duab yog ib qho kev ntsuas uas siv los ua cov txheej txheem ua phaj. Nws tuaj yeem ntsuas qhov txheej txheem ntawm lub photoresist ntawm qhov screen. Nws yog tsuas yog siv rau kev kuaj lub phaj luam tawm ntawm cov ntawv luam tawm Circuit Court boards, iav kom zoo nkauj, kho kom zoo nkauj, porcelain hloov daim ntawv thiab kev luam ntawv tshwj xeeb.
Qhov chaw ntom zuaj roughness
Qhov chaw ntom zuaj ntawm qhov chaw txias yog ib qho cuab yeej tshwj xeeb los ntsuas qhov kev nyob ntawm tus npoo ntawm qhov screen. Lub flatness ntawm qhov screen nto plays lub luag hauj lwm tseem ceeb hauv luam ntawv siab zoo screen printing. Yog hais tias qhov txheej av npoo ntawm qhov screen yog ib yam nkaus thiab, cov ntawv luam tawm nws yog burrs thiab serrations, uas cuam tshuam qhov zoo ntawm cov ntawv luam tawm. Lub roughness ntawm qhov npoo ntawm qhov screen feem ntau qhia los ntawm tus nqi Rz. Rz tus nqi yuav tsum yog qis dua 10 μm, thiab yog tias nws tshaj li 25 μm, qhov luam yuav raug cuam tshuam.
