1. Lub hom phiaj ntawm PCB tsim yuav tsum pom meej. Rau cov teeb liab tseem ceeb, qhov ntev ntawm cov xaim hluav taws xob thiab cov khoom lag luam hauv av yuav tsum nruj heev. Rau cov kab mob qis thiab tsis tseem ceeb, nws tuaj yeem muab tso rau ntawm qhov chaw qis qis me ntsis. Cov. Qhov tseem ceeb hauv thaj chaw muaj xws li: Kev faib khoom siv hluav taws xob; Ntev yuav tsum tau ntawm nco moos moos, tswj cov kab thiab cov ntaub ntawv kab; Kev xaim ntawm cov kab nrawm, thiab lwm yam hauv qhov project a, lub cim xeeb nti yog siv los paub DDR nco nrog ib qho loj ntawm 1G. Cov xaim rau ntu no yog qhov tseem ceeb heev. Qhov kev faib tawm todology Nyob rau hauv cov txheej txheem, raws li cov ntawv teev cov ntaub ntawv ntawm lub nti thiab kev ua haujlwm tiag tiag, cov kev cai hlau tshwj xeeb tuaj yeem tau txais. Piv txwv li, qhov ntev ntawm cov ntaub ntawv kab hauv tib pab pawg yuav tsum tsis sib txawv ntawm ntau dua ob peb mais kev, thiab qhov ntev sib txawv ntawm txhua tus channel yuav tsum tsis pub tshaj li cas muaj ntau yam Mils. mil thiab li ntawd. Thaum cov kev xav tau no tau txiav txim siab, cov kws tsim duab PCB tuaj yeem ua kom pom tseeb tias lawv yuav siv tau. Yog tias tag nrho cov kev coj ua tseem ceeb hauv tus qauv tsim muaj tseeb, lawv tuaj yeem hloov pauv mus rau hauv kev txiav txim siab tag nrho software hauv CAD siv tau los paub txog tus qauv PCB. Nws tseem yog ib qho kev txhim kho nyob rau hauv tus qauv tsim nrawm pcb.

2. Kev tshuaj xyuas thiab debugging thaum npaj kom deb li cas cov qauv tshuaj tiv thaiv, thiab tom qab ntawd nws muaj kev sib dhos ua ke ntawm txhua tus pin, thiab tom qab ntawd nws muaj cov khoom siv luv luv ntawm kev tshuaj xyuas seb puas muaj Circuit Court. Qhov kev coj cwj pwm zoo no tuaj yeem zam kev puas tsuaj rau pawg thawj coj tom qab Rashly Powering. Thaum koj yuav tsum muaj kev thaj yeeb nyab xeeb. Nws yog ib qho zoo li qub los ntsib teeb meem. Dab tsi koj yuav tsum tau ua yog ua ntau qhov sib piv thiab tsom xam, thiab maj mam tshem tawm cov ua rau muaj. Koj yuav tsum ntseeg kom ncaj "txhua yam tuaj yeem daws teeb meem" thiab "teeb ​​meem yuav tsum daws tau." Muaj qhov laj thawj rau nws ", kom cov debugging yuav ua tiav thaum kawg.

3. Ib qho ntsiab lus ntsiab lus tam sim no los ntawm cov txuj ci kev saib, tab sis kuj tau npaj ua tiav, pab tau cov khoom siv ua kom zoo thiab cov neeg ua haujlwm tuaj yeem ua rau muaj kev vam meej ntawm ib txoj haujlwm. Tus kws kho vajtse zoo yog qhov tseeb tus thawj tswj haujlwm. Nws yuav tsum sib txuas lus nrog sab nraud ntiaj teb kom tau txais rau lawv tus kheej tsim, thiab tom qab ntawd nthuav dav thiab txheeb xyuas lawv mus rau hauv cov khoom siv kho vajtse. Nws tseem tsim nyog yuav tau hu rau ntau cov nti thiab cov khoom siv tov los xaiv cov tshuaj tsim nyog. Thaum schematic daim duab ua tiav, nws yuav tsum teeb cov npoj yaig sib koom tes nrog kev tshuaj xyuas thiab tshuaj xyuas nrog CAD engineers los ua tiav PCB tsim. Cov. Nyob rau tib lub sijhawm, npaj cov npe BOM, pib yuav khoom thiab npaj cov ntaub ntawv, thiab hu rau cov chaw tsim khoom lag luam kom tiav cov pawg tswj hwm. Nyob rau hauv cov txheej txheem ntawm debugging, nws yuav tsum npaj software engineers kom daws cov teeb meem tseem ceeb, thiab tos kom txog thaum cov khoom lag luam tau tsim rau lub xaib. Yog tias muaj teeb meem, nws yuav tsum tau txais kev txhawb nqa hauv lub sijhawm. Yog li ntawd, los ua tus tsim kho vajtse, koj yuav tsum muaj kev sib txuas lus zoo, muaj peev xwm txiav txim siab nrog ntau yam haujlwm tib lub sijhawm, thiab tus cwj pwm zoo thiab muaj kev thaj yeeb. Kuj tseem muaj kev saib xyuas thiab qhov loj, vim tias ib qho kev tsis saib xyuas me me hauv kev tsim kho vajtse tsim tau feem ntau ua rau muaj kev poob siab loj. Piv txwv li, thaum lub rooj tsavxwm tau tsim thiab cov ntaub ntawv tsim khoom tau ua tiav ua ntej, qhov tsis zoo tshwm sim los ntawm txheej fais thiab txheej av kom txuas nrog. Nyob rau tib lub sijhawm, tom qab PCB pawg thawj coj saib yog tsim tawm, nws tau ncaj qha rau ntawm kab ntau lawm yam tsis tau tshuaj xyuas. Nws tsuas yog thaum sim ntawd qhov teeb meem luv luv hauv CirciCuit tau pom, tab sis cov khoom siv tau soldered rau lub rooj tsavxwm, uas ua rau ntau pua txhiab tus poob. Yog li ntawd, ceev faj thiab kev soj ntsuam thiab loj, thiab tsub zuj zuj tuaj yeem ua rau tus tsim kho vajtse ua kom tiav, thiab tom qab ntawd ua qee qhov ua tiav hauv kev lag luam.
