PCB tsim screen luam ntawv yog dab tsi? Vim li cas lawv thiaj suav nrog hauv txoj kev npaj tsim? Puas yog koj lub PCB xav tau los ua ib qho screen nyeem tau?
Qhov screen printing yog dab tsi?
Feem ntau, cov ntawv luam tawm Circuit Board (PCB) tsim muaj ntau txheej txheej, thiab cov txheej txheem tshuaj ntsuam yog ib qho ntawm cov txheej txheem no. Txij li thaum lub silk screen yuav tsum tau luam tawm rau saum npoo ntawm PCB, txhua lub PCB muaj nyob rau hauv feem ntau ntawm ob lub npov lo lo ntxhuav, uas yog sab saum toj thiab hauv qab. Silk screen tuaj yeem luam tawm cov ntaub ntawv ntawm cov duab los qhia rau tib neeg los nyeem thiab txhais. Ntawm lub vijtsam silk ntawm PCB, koj tuaj yeem luam tawm ntau yam ntaub ntawv xws li cov khoom siv ntsuas ntsuas, lub tuam txhab logo, cov khoom lag luam logo, cov cim ceeb toom, cov lej, cov lej, thiab cov lej hnub tim. Tab sis qhov chaw ntawm PCB nto yog txwv, yog li nws yog qhov zoo tshaj los txwv nws rau cov ntaub ntawv tseem ceeb lossis cov ntaub ntawv tseem ceeb. Yog li ntawd, cov khaubncaws sab nraud povtseg feem ntau tsuas yog txuag cov lus dab neeg, qhia txog txoj haujlwm ntawm ntau yam khoom ntawm lub tuam txhab logo thiab Circuit Board tsim tus lej.
Tam sim no, kev cai digital inkjet tshuab luam ntawv tshwj xeeb rau luam ntawv PCBs feem ntau yog siv los luam tawm cov duab luam tawm los ntawm Circuit Board tsim cov ntaub ntawv mus rau PCB nto. Thawj qhov kev tshuaj ntsuam luam ntawv yog siv txoj kev tshuaj ntsuam luam ntawv kom tau txais lub npe tshuaj ntsuam luam ntawv los ntawm nws. Lub npe yog vim lub tshuab luam ntawv ib txwm siv uas yuav tsum tau siv cov ntaub zoo xws li txhob lo lo ntxhuav los yog polyester ua ib qho screen thiab ib lub thav duab ua los ntawm ntoo, txhuas, thiab lwm yam. Tam sim no nrog rau kev nce qib ntawm cov cuab yeej technology, ntau yam sib txawv yooj yim los yog sai dua screen printing txoj kev yog tsim, tab sis lub npe tseem zoo li qub.
Yuav tsim qhov screen li cas?
Nws yog ib qho tsim nyog sau cia tias kev hloov kho cov ntawv lo lo ntxhuav nyob rau hauv cov ntawv luam tawm Circuit Board tsim yog ib kauj ruam me me ntawm cov ntawv luam tawm Circuit board tsim, vim tias cov silk screen tsis tas yuav tsum tau sib sau ua ke ntawm cov ntawv luam tawm Circuit Board. Txawm li cas los xij, txawm hais tias qhov no tsis yog qhov tsim nyog kiag li, nws tseem yog ib qho tseem ceeb rau kev pab cuam lub rooj sib tham hauv Circuit Court los ntawm kev muab cov ntaub ntawv xa mus rau kev tsim kho thiab kev daws teeb meem. Muaj ntau yam khoos phis tawj rau PCB tsim nyob rau hauv kev ua lag luam, xws li Mentorgraphic PAD layout thiab router. Rau Mentorgraphic PAD thaum tsim lub PCB layout thaum muab cov khoom sib xyaw rau hauv cov txheej txheem ntawm cov ntaub ntawv tsim, ib qho kev qhia siv cov khoom siv yuav raug xa mus rau txhua qhov ntawm cov khoom tsim.
Thaum tsim cov txheej txheem PCB, peb txav thiab tig cov khoom ntawm cov txheej txheem. Cov khoom siv ntsuas ntsuas cov lej txav thiab tig raws li lawv txuas nrog rau cov khoom siv. Yog li ntawd, kho qhov screen yuav tsum tau nyob rau hauv cov ntaub ntawv no. Tseem muaj cov kev pab cuam uas koj tuaj yeem tsim cov ntxaij vab tshaus thiab sau cov cim qhia cov cim koj tus kheej kom lawv tuaj yeem siv nrog cov chaw sib txuas. Hauv cov txheej txheem no, koj tsuas yog yuav tsum tau ua tib zoo mloog cov ntsiab lus hauv qab no, thiab ua tib zoo saib xyuas cov cai sib txawv rau txhua qhov khoom.
Kev taw qhia / sib tshooj
Txawm hais tias koj tab tom kho qhov kev tsim cov ntawv luam tawm los yog tsim cov txheej txheem luam ntawv los ntawm kos, yog tias koj xav tsim cov ntawv luam tawm txheej tsim nrog kev nyeem tau zoo, koj yuav tsum tau xyuam xim rau qee cov ntsiab lus tseem ceeb. Txhawm rau tsim lub vijtsam zoo, koj yuav tsum: kho cov ntawv qhia kev qhia ntawm cov khoom siv qhia, ib feem, thiab lwm yam kom txhua tus muaj cov kev taw qhia tib yam, yog tias ua tau, teeb tsa saum toj thiab hauv qab, uas txhais tau tias lub vijtsam. nyeem tau yooj yim dua.
Ua ntej tig cov ntawv nyeem thiab kho cov cim qhia siv cov khoom siv, xyuas cov teeb meem tshwm sim nrog cov ntawv sib tshooj. Piv txwv li, raws li pom hauv daim duab 1, cov cim muaj cov lus qhia sib txawv thiab sib tshooj. Hauv daim duab, koj tuaj yeem pom yuav ua li cas siv lub cim raws li kev siv thaum sib dhos, thiab yuav ua li cas tsis meej pem thiab nyuaj yog tias nws tsis raug kho. Yog li ntawd, koj yuav tsum tig thiab txav cov khoom siv siv cim rau qhov tseeb kev taw qhia thiab txoj hauj lwm ntawm cov khoom sib txuas.
