PCB board ua yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob tsim khoom. Txhawm rau kom ua tiav kev ua haujlwm ntawm PCB pawg thawj coj saib, nws yog qhov yuav tsum tau npaj qee cov ntaub ntawv tsim nyog; Yog li dab tsi cov ntaub ntawv xav tau rau PCB board ua thiab yuav ua li cas npaj cov ntaub ntawv no.
Ua ntej, cov ntaub ntawv yooj yim xav tau rau PCB pawg thawj coj saib yog Gerber cov ntaub ntawv. Gerber cov ntaub ntawv yog cov qauv qhib siv los qhia cov kev xav tau ntawm PCBs. Nws muaj cov ntaub ntawv los ntawm ntau cov khaubncaws sab nraud povtseg ntawm PCB, xws li tooj liab txheej, silk screen khaubncaws sab nraud povtseg, solder mask txheej, thiab lwm yam. Yuav kom tau Gerber cov ntaub ntawv, nws yog tsim nyog los siv PCB tsim software export lub PCB layout nyob rau hauv Gerber ntaub ntawv hom. Tsis tas li ntawd, thaum xa tawm cov ntaub ntawv Gerber, nws yog ib qho tsim nyog los xyuas kom meej tias cov txheej txheem thiab cov txheej txheem raug xaiv kom cov PCB board tuaj yeem tsim tau raug rau hauv cov txheej txheem PCB tom ntej.
Qhov thib ob, kev tsim PCB pawg thawj coj kuj xav tau kev npaj ntawm Daim Ntawv Pov Thawj Cov Khoom (BOM). BOM lub rooj hais txog cov npe ntawm ntau yam khoom siv hauv PCB, suav nrog cov ntaub ntawv xws li cov qauv qauv, cov chaw muag khoom, cov khoom, thiab lwm yam. Los ntawm kev sau cov lus BOM kom raug, nws tuaj yeem ua kom ntseeg tau tias cov khoom tsim nyog tuaj yeem xaiv thiab teeb tsa kom raug thaum lub sijhawm. PCB board ua txheej txheem. Txhawm rau npaj BOM rooj, tshwj xeeb BOM tswj software tuaj yeem siv tau, lossis BOM lub rooj tuaj yeem sau tau manually.
Tsis tas li ntawd, cov npe ntawm cov khoom yuav tsum tau muab tso ua ke. Ib daim ntawv teev npe yog ib daim ntawv qhia ntxaws ntxaws ntawm ntau yam khoom siv hauv PCB, feem ntau suav nrog cov lus qhia tshwj xeeb, yam ntxwv, kev ua haujlwm, tus pin txhais, thiab lwm yam ntaub ntawv hais txog cov khoom. Lub hom phiaj ntawm kev sau ib daim ntawv teev npe yog los pab cov tuam txhab PCB kom nkag siab zoo txog kev xav ntawm cov neeg tsim qauv thiab zam kev nkag siab yuam kev thiab tsis raug. Daim ntawv teev npe tuaj yeem muab sib xyaw nrog BOM lub rooj lossis xa ua ib daim ntawv ntxiv.
Tsis tas li ntawd, thaum npaj cov ntaub ntawv PCB layout, nws tseem yuav tsum tau them sai sai rau qee cov ntsiab lus. Ua ntej, sim siv cov qauv ntaub ntawv xws li ASCII Gerber cov ntaub ntawv thiab Excel BOM cov lus. Qhov no tuaj yeem txhim kho cov ntaub ntawv sib cuam tshuam nrog cov tuam ntxhab thiab zam cov teeb meem kev sib haum xeeb. Qhov thib ob, nws yog ib qho tseem ceeb kom ntseeg tau tias cov ntaub ntawv npaj tau yog qhov tseeb version kom tsis txhob muaj kev ua yuam kev thaum lub sijhawm tsim khoom vim muaj teeb meem nrog cov ntawv qub qub.
