9. Kev daws teeb meem yog dab tsi? Teb: Nyob rau hauv ib qhov deb ntawm 1 hli, qhov kev daws teeb meem ntawm cov kab los yog cov kab sib txuas uas tuaj yeem tsim los ntawm cov yeeb yaj kiab qhuav kuj tuaj yeem qhia los ntawm qhov loj ntawm cov kab lossis qhov sib txawv.Qhov sib txawv ntawm cov yeeb yaj kiab qhuav thiab cov yeeb yaj kiab tiv taus Lub thickness ntawm polyester zaj duab xis yog cuam tshuam.Lub thicker lub resist film txheej, qhov kev daws teeb meem qis dua.Thaum lub teeb dhau los ntawm cov duab thaij duab thiab cov yeeb yaj kiab polyester thiab cov yeeb yaj kiab qhuav raug nthuav tawm, vim qhov tawg ntawm lub teeb los ntawm polyester zaj duab xis, qhov sib dua ntawm qhov hnyav, qhov kev daws teeb meem qis dua. 
10. Dab tsi yog qhov etching tsis kam thiab electroplating tsis kam ntawm PCB qhuav zaj duab xis? Teb: Etching kuj: Cov zaj duab xis qhuav tiv thaiv txheej tom qab photopolymerization yuav tsum muaj peev xwm tiv taus cov hlau trichloride etching tov, persulfuric acid etching tov, acid chlorine, tooj liab etching tov, sulfuric acid-hydrogen peroxide etching tov.Nyob rau hauv cov saum toj no etching tov, thaum kub yog 50-55 ° C, nto ntawm cov zaj duab xis qhuav yuav tsum tsis muaj plaub hau, to, warping thiab shedding.Electroplating kuj: nyob rau hauv acidic ci tooj liab plating, fluoroborate zoo tib yam hlau lead alloy, fluoroborate ci tin-lead alloy plating thiab ntau yam pre-plating kev daws teeb meem ntawm saum toj no electroplating, cov zaj duab xis qhuav tiv thaiv txheej tom qab polymerization yuav tsum tsis muaj deg plaub hau, infiltration, warping thiab shedding. . 11. Vim li cas lub tshuab raug yuav tsum nqus lub tshuab nqus tsev thaum nthuav tawm? Teb: Hauv kev ua haujlwm tsis muaj teeb pom kev zoo (cov tshuab raug nrog "cov ntsiab lus" raws li lub teeb ci), qhov nqus nqus nqus yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm qhov raug.Cua kuj yog ib txheej nruab nrab., muaj huab cua nyob nruab nrab ntawm cov huab cua extraction zaj duab xis, ces nws yuav tsim lub teeb refraction, uas yuav cuam tshuam cov nyhuv ntawm raug.Lub tshuab nqus tsev tsis yog tsuas yog tiv thaiv lub teeb pom kev zoo xwb, tab sis kuj tseem tiv thaiv qhov sib txawv ntawm cov yeeb yaj kiab thiab lub rooj tsavxwm los ntawm kev nthuav dav, thiab ua kom muaj kev sib raug zoo / Qhov zoo ntawm qhov raug.
12. Dab tsi yog qhov zoo ntawm kev siv volcanic tshauv sib tsoo phaj rau pretreatment? ua tsis tau? Teb: Qhov zoo: a.Kev sib xyaw ua ke ntawm abrasive pumice hmoov hais thiab nylon txhuam yog tangentially rubbed nrog paj rwb ntaub, uas tuaj yeem tshem tawm tag nrho cov av thiab nthuav tawm cov tooj liab tshiab thiab ntshiab;b.Nws tuaj yeem tsim cov xuab zeb-grained tag nrho, ntxhib thiab tsis sib xws D. Qhov chaw thiab lub qhov yuav tsis raug puas vim cov nyhuv softening ntawm cov nylon txhuam;d.Qhov yooj yim ntawm cov nylon txhuam txhuam tuaj yeem ua rau qhov teeb meem ntawm cov phaj tsis sib xws los ntawm txhuam hnav;e.Txij li cov phaj saum npoo tsis sib xws thiab tsis muaj grooves, qhov tawg ntawm lub teeb raug txo qis, yog li kev txhim kho cov kev daws teeb meem ntawm cov duab.Disadvantages: Qhov tsis zoo yog tias cov hmoov pumice yog ib qho yooj yim rau kev puas tsuaj rau cov khoom siv hluav taws xob, kev tswj xyuas qhov loj me me ntawm cov hmoov pumice thiab tshem tawm cov pumice hmoov residue ntawm qhov chaw ntawm lub substrate (tshwj xeeb tshaj yog nyob rau hauv lub qhov. ).
13. Yuav ua li cas yuav ua rau lub Circuit Court tsim taw tes loj dhau los yog tsawg dhau? Teb: Lub sij hawm tsim kho kom raug yog txiav txim siab los ntawm qhov taw qhia kev txhim kho (lub ntsiab lus uas cov yeeb yaj kiab qhuav tsis raug tshem tawm ntawm cov ntawv luam tawm).Lub ntsiab lus ntawm txoj kev loj hlob yuav tsum tau khaws cia ntawm qhov feem pua ntawm tag nrho qhov ntev ntawm txoj kev loj hlob.Yog hais tias qhov kev loj hlob yog ze ze rau ntawm qhov hluav taws xob ntawm qhov chaw tsim, cov yeeb yaj kiab uas tsis muaj polymerized yuav tsis raug ntxuav thiab tsim kom txaus, thiab cov residue residue yuav nyob twj ywm rau ntawm lub rooj tsavxwm thiab ua rau kev loj hlob tsis huv.Yog tias qhov chaw tsim kho nyob ze dhau ntawm qhov nkag ntawm qhov kev txhim kho, cov yeeb yaj kiab polymerized qhuav tuaj yeem raug etched los ntawm Na2C03 thiab ua plaub hau vim kev sib cuag ntev nrog kev tsim kho.Feem ntau qhov kev txhim kho yog tswj tsis pub dhau 40% -60% ntawm tag nrho qhov ntev ntawm qhov kev loj hlob (35% -55% ntawm peb lub tuam txhab). 14. Vim li cas peb thiaj li yuav tsum tau ua ntej ci lub rooj tsavxwm ua ntej cov cim luam tawm? Teb: Lub rooj tsavxwm ua ntej ci a yog txhawm rau txhim kho lub zog sib txuas ntawm lub rooj tsavxwm thiab cov cim ua ntej cov cim luam tawm, thiab b txhawm rau txhim kho cov tawv tawv ntawm cov nplaum nplaum nplaum rau ntawm qhov chaw ntawm lub rooj tsavxwm kom tiv thaiv tau lub npog ntsej muag roj hla -spreading tshwm sim los ntawm cov cim luam ntawv lossis ua tiav tom qab. 15. Vim li cas peb thiaj li yuav tsum tau viav vias txhuam ntawm lub tshuab ua ntej kev kho mob phaj sib tsoo? Teb: Muaj qee qhov kev ncua deb ntawm tus txhuam tus pin reels.Yog tias koj tsis siv cov sway los zom cov phaj, yuav muaj ntau qhov chaw uas yuav tsis hnav, ua rau tsis sib xws ntawm cov phaj saum npoo.Yog tsis muaj swaying, ib tug ncaj zawj yuav raug tsim rau ntawm lub phaj nto.Ua rau cov hlau tawg, thiab nws yog ib qho yooj yim rau tawg qhov thiab tsim tailing phenomenon tsis viav vias ntawm ntug ntawm lub qhov. 16. Dab tsi cuam tshuam rau kev luam ntawv? Teb: Lub kaum sab xis ntawm lub squeegee ncaj qha tswj tus nqi ntawm cov roj, thiab qhov sib xws ntawm cov hniav mus rau saum npoo ncaj qha cuam tshuam rau qhov zoo ntawm cov luam ntawv. 17. Dab tsi yog qhov cuam tshuam ntawm daim npog ntsej muag thiab qhov kub thiab txias hauv chav tsaus ntawm PCB ntau lawm? Teb: Thaum qhov kub thiab av noo hauv chav tsaus yog siab dhau lossis qis dhau: 1. Nws yuav ua rau cov khib nyiab hauv huab cua ntau ntxiv, 2. Cov yeeb yaj kiab nplaum yog ib qho yooj yim tshwm sim nyob rau hauv kev sib dhos, 3. Nws yog ib qho yooj yim ua rau cov zaj duab xis rau deform, 4. Nws yog ib qho yooj yim ua rau lub rooj tsavxwm nto oxidize. 18. Vim li cas ho tsis siv lub npog ntsej muag los ua qhov tsim kho? Teb "Vim tias muaj ntau yam sib txawv hauv cov xim pleev xim rau cov xim pleev xim. Ua ntej ntawm tag nrho cov hom inks yog ntau thiab ntau nyuaj. Cov khoom ntawm txhua tus number case txawv. Lub zog ntawm lub zog, ceev thiab viscosity, lawv tsis zoo ib yam li cov yeeb yaj kiab qhuav, lub thickness ntawm ib zaj duab xis yog ntau yam zoo tib yam, tib lub sij hawm, lub solder tiv thaiv number case kuj cuam tshuam los ntawm qhov sib txawv ci lub sij hawm, qhov kub thiab txias. Thaum lub sij hawm tsim cov txheej txheem, cov nyhuv ntawm lub rooj tsavxwm yog tib yam, yog li cov tswv yim tseem ceeb ntawm solder mask raws li qhov kev loj hlob taw tes tsis zoo.
