Kev ceev faj rau PCB Board Printing: Phau Ntawv Qhia rau Solder Mask Ink

Qhia:

Thaum tsim cov ntawv luam tawm Circuit Board (PCBs), siv cov ntaub ntawv thiab cov txheej txheem tsim nyog yog qhov tseem ceeb los xyuas kom meej qhov ua tau zoo thiab kev ntseeg tau.Ib qho tseem ceeb ntawm PCB ntau lawm yog daim ntawv thov ntawm daim npog ntsej muag, uas yuav pab tiv thaiv cov kab tooj liab thiab tiv thaiv cov txuas hniav thaum sib dhos.Txawm li cas los xij, kom tau txais cov txiaj ntsig zoo PCB board luam ntawv, qee qhov kev ceev faj yuav tsum tau ua raws.Hauv tsab ntawv tshaj tawm no, peb yuav tham txog cov kev ceev faj tsim nyog uas yuav tsum tau txiav txim siab thaum tuav lub npog ntsej muag, qhia txog cov ntsiab lus tseem ceeb kom tswj tau qhov zoo thiab ua haujlwm.

1. Xaiv qhov tsim nyog lub npog ntsej muag number case:

Xaiv qhov zoo ntawm daim npog ntsej muag yog qhov tseem ceeb rau kev ua tiav kev txhim khu kev qha thiab zoo ib yam.Qhov zoo tshaj plaws, tus cwj mem xaiv yuav tsum muab qhov zoo tshaj plaws adhesion rau PCB nto, muaj cov cua kub tsis kam, thiab muaj hluav taws xob rwb thaiv tsev zoo.Cov yam ntxwv xws li lub rooj tsav xwm hauv Circuit Court, cov txheej txheem tsim khoom, thiab cov yam ntxwv ntawm PCB yuav tsum raug txiav txim siab thaum txiav txim siab qhov tseem ceeb no.

2. Kev cia thiab tuav kom zoo:

Thaum tau txais cov ntawv nplaum daim npog ntsej muag, kev cia thiab tuav kom zoo yog qhov tseem ceeb rau kev tswj nws qhov kev ua tau zoo.Nws raug nquahu kom khaws cov number case rau hauv qhov chaw txias, qhuav kom deb ntawm lub hnub ncaj qha thiab kub hloov pauv.Xyuas kom lub thawv ntim tau kaw thaum tsis siv kom tsis txhob ziab tawm lossis paug ntawm tus number case.Kev tswj kom tsim nyog, xws li hnav hnab looj tes thiab ceev faj tiv thaiv kom tsis txhob nchuav thiab sib cuag ntawm daim tawv nqaij, yuav tsum tau siv los ua kom tus kheej muaj kev nyab xeeb thiab ua kom muaj kev ncaj ncees ntawm tus number case.

3. Kev kho deg:

Ua tiav daim ntawv thov daim npog ntsej muag zoo meej yuav tsum tau npaj txhij txhua.Ua ntej siv tus cwj mem, PCB nto yuav tsum tau muab ntxuav kom tshem tawm cov kab mob xws li plua plav, roj, lossis cov ntiv tes.Cov txheej txheem tu kom zoo, xws li siv cov tshuaj PCB tshwj xeeb thiab cov ntaub tsis muaj lint, yuav tsum tau siv los xyuas kom meej qhov chaw huv.Txhua qhov seem seem lossis impurities sab laug rau ntawm lub rooj tsavxwm yuav ua rau tsis zoo rau qhov adhesion thiab tag nrho kev ua haujlwm ntawm tus number case.

4. Kev txiav txim siab ntawm ib puag ncig yam tseem ceeb:

Ib puag ncig tej yam kev mob ua lub luag haujlwm tseem ceeb hauv kev ua kom pom qhov zoo ntawm daim npog ntsej muag daim ntawv thov.Cov yam ntxwv xws li qhov kub thiab txias yuav tsum tau saib xyuas zoo thiab tswj tau nyob rau hauv cov kev txwv tshwj xeeb uas tau teev tseg los ntawm cov chaw tsim khoom number case.Kev kub ntxhov lossis hloov pauv ib puag ncig tuaj yeem cuam tshuam rau tus lej viscosity, lub sijhawm ziab thiab cov khoom adhesion, ua rau cov ntawv luam tawm tsis zoo.Tsis tu ncua calibration ntawm ib puag ncig tswj cov cuab yeej raug pom zoo kom tswj cov xwm txheej uas yuav tsum tau muaj thoob plaws hauv cov txheej txheem tsim khoom PCB.

5. Kev siv technology:

Kev thov kom raug ntawm daim npog ntsej muag yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig xav tau.Xav txog kev siv cov cuab yeej siv tsis siv neeg xws li tshuab luam ntawv tshuaj ntsuam lossis inkjet txoj kev los xyuas kom meej thiab zoo ib yam.Ua tib zoo siv tus lej ntawm tus number case kom ua tiav, tab sis tsis yog tuab heev.Kev tswj kom zoo ntawm tus cwj mem ntws, lub vijtsam nro, thiab squeegee siab (nyob rau hauv cov ntaub ntawv ntawm kev tshuaj ntsuam luam ntawv) yuav pab ua kom tiav cov ntawv sau npe thiab tiv thaiv qhov tsis xws luag xws li pinholes, los ntshav, lossis bridging.

6. Kho thiab ziab:

Cov kauj ruam kawg hauv daim ntawv thov daim npog ntsej muag yog kev kho thiab ziab.Ua raws li cov chaw tsim khoom cov lus qhia txog qhov kub thiab txias thiab lub sijhawm xav tau rau tus number case los kho kom zoo.Tsis txhob ua cua sov los yog txias sai vim qhov no yuav ua rau muaj kev ntxhov siab lossis delamination ntawm cov xim pleev xim.Xyuas kom lub sij hawm ziab kom txaus ua ntej yuav ua cov txheej txheem tsim khoom tom ntej xws li muab tso rau hauv cov khoom siv los yog cov khoom siv soldering.Kev tswj xyuas qhov sib xws hauv kev kho thiab ziab kom qhuav yog qhov tseem ceeb kom tau txais lub ntsej muag zoo li qub thiab ruaj khov.

Hauv kev xaus:

Thaum ua haujlwm nrog cov ntaub npog ntsej muag, ua raws li kev ceev faj tsim nyog thaum lub sij hawm PCB board luam ntawv txheej txheem yog qhov tseem ceeb los xyuas kom meej cov txiaj ntsig zoo, txhim khu kev qha thiab kav ntev.Los ntawm kev ua tib zoo xaiv tus cwj mem zoo ntawm lub npog ntsej muag, xyaum ua kom zoo thiab tuav, npaj kom txaus, tswj hwm ib puag ncig, siv cov txheej txheem thov raug, thiab ua raws li cov txheej txheem kho thiab ziab, cov tuam txhab tuaj yeem tsim cov PCBs tsis zoo thaum tswj cov txheej txheem ntau lawm.Kev ua raws li cov kev ceev faj no tuaj yeem txhim kho lub peev xwm ntawm PCB kev lag luam kev lag luam, txo qhov tsis xws luag, thiab ua kom cov neeg siv khoom txaus siab.
