1. Lub hom phiaj ntawm PCB tsim yuav tsum meej. Rau cov kab teeb liab tseem ceeb, qhov ntev ntawm kev xaim thiab kev ua hauv av yuav tsum nruj heev. Rau cov kab hluav taws xob qis thiab tsis tseem ceeb, nws tuaj yeem muab tso rau ntawm qhov tseem ceeb ntawm kev xaim me ntsis. . Cov khoom tseem ceeb muaj xws li: kev faib hluav taws xob; ntev yuav tsum tau ntawm lub cim xeeb moos kab, tswj kab thiab cov ntaub ntawv kab; Kev xaim ntawm cov kab sib txawv ntawm cov kab sib txawv ntawm kev kub ceev, thiab lwm yam hauv qhov project A, lub cim xeeb nti yog siv los paub txog DDR nco nrog qhov loj ntawm 1G. Cov kab mob rau qhov no yog qhov tseem ceeb heev. Lub topology faib ntawm cov kab tswj thiab chaw nyob kab, thiab qhov ntev sib txawv tswj cov ntaub ntawv kab thiab moos kab yuav tsum tau txiav txim siab. Nyob rau hauv tus txheej txheem, raws li cov ntaub ntawv ntawm lub nti thiab qhov tseeb kev khiav hauj lwm zaus, cov kev cai tshwj xeeb yuav tau txais. Piv txwv li, qhov ntev ntawm cov ntaub ntawv kab nyob rau hauv tib pab pawg yuav tsum tsis txhob sib txawv ntau tshaj li ob peb mils, thiab qhov ntev sib txawv ntawm txhua channel yuav tsum tsis txhob ntau tshaj li cas mils. mil lwm. Thaum cov kev xav tau no tau txiav txim siab, PCB cov neeg tsim qauv tuaj yeem tsim kom pom tseeb los siv lawv. Yog tias tag nrho cov kev xav tau tseem ceeb hauv kev tsim qauv yog qhov tseeb, lawv tuaj yeem hloov mus rau hauv tag nrho cov kev txwv, thiab cov cuab yeej siv tsis siv neeg routing software hauv CAD tuaj yeem siv los paub txog PCB tsim. Nws kuj yog ib qho kev txhim kho hauv kev kub ceev PCB tsim.

2. Kev tshuaj xyuas thiab kev debugging Thaum npaj rau debug lub rooj tsavxwm, nco ntsoov ua tib zoo saib xyuas ua ntej, xyuas seb puas muaj qhov pom luv luv thiab tus pin tin tsis ua haujlwm thaum lub sij hawm soldering, thiab xyuas seb puas muaj cov qauv kev tivthaiv tso rau ntawm qhov yuam kev, qhov chaw tsis raug. ntawm thawj tus pin, uas ploj lawm los ua ke, thiab lwm yam, thiab tom qab ntawd siv lub multimeter los ntsuas qhov tsis kam ntawm txhua lub zog hluav taws xob rau hauv av los xyuas seb puas muaj qhov luv luv. Tus cwj pwm zoo no tuaj yeem zam kev puas tsuaj rau lub rooj tsavxwm tom qab rashly powering on. Nyob rau hauv tus txheej txheem ntawm debugging, koj yuav tsum muaj lub siab kaj siab lug. Nws yog ib txwm muaj teeb meem heev. Qhov koj yuav tsum tau ua yog ua kom muaj kev sib piv thiab kev tshuaj xyuas ntau dua, thiab maj mam tshem tawm qhov ua tau. Koj yuav tsum ntseeg ruaj khov tias "txhua yam tuaj yeem daws tau" thiab "cov teeb meem yuav tsum tau daws." Muaj ib qho laj thawj rau nws ", yog li ntawd qhov kev debugging yuav ua tiav thaum kawg ..

3. Qee cov lus luv luv Tam sim no los ntawm kev pom zoo, txhua qhov kev tsim qauv tuaj yeem ua tiav, tab sis kev ua tiav ntawm ib qhov project yog nyob ntawm qhov kev siv ntawm kev siv, tab sis kuj nyob rau lub sijhawm ua tiav, cov khoom zoo, pab pawg yog li ntawd, kev ua haujlwm zoo, Transparent thiab candid project kev sib txuas lus, ua tib zoo tshawb nrhiav thiab kev txhim kho kev npaj, thiab ntau cov ntaub ntawv thiab kev npaj cov neeg ua haujlwm tuaj yeem ua kom tiav ntawm qhov project. Ib tug zoo hardware engineer yeej yog ib qhov project manager. Nws yuav tsum tau sib txuas lus nrog lub ntiaj teb sab nraud kom tau txais cov kev xav tau rau lawv tus kheej tsim, thiab tom qab ntawd sau cov ntsiab lus thiab txheeb xyuas lawv rau hauv kev siv kho vajtse tshwj xeeb. Nws kuj tseem yuav tsum tau hu rau ntau lub nti thiab cov neeg muab kev daws teeb meem los xaiv cov kev daws teeb meem tsim nyog. Thaum daim duab kos duab tiav lawm, nws yuav tsum npaj cov npoj yaig los koom tes nrog kev tshuaj xyuas thiab tshuaj xyuas, thiab tseem ua haujlwm nrog CAD engineers los ua kom tiav PCB tsim. . Nyob rau tib lub sijhawm, npaj BOM daim ntawv teev npe, pib yuav khoom thiab npaj cov ntaub ntawv, thiab hu rau cov chaw tsim khoom ua kom tiav cov chaw tso khoom. Nyob rau hauv tus txheej txheem ntawm kev debugging, nws yuav tsum npaj software engineers los daws cov teeb meem tseem ceeb ua ke, koom tes nrog cov kws tshaj lij kev sim los daws cov teeb meem pom hauv qhov kev sim, thiab tos kom txog thaum cov khoom tsim tawm mus rau qhov chaw. Yog tias muaj teeb meem, nws yuav tsum tau txais kev txhawb nqa hauv lub sijhawm. Yog li ntawd, txhawm rau ua tus tsim kho vajtse, koj yuav tsum siv cov txuj ci kev sib txuas lus zoo, muaj peev xwm hloov kho siab, muaj peev xwm sib koom tes thiab txiav txim siab thaum cuam tshuam nrog ntau yam xwm txheej tib lub sijhawm, thiab tus cwj pwm zoo thiab kev thaj yeeb. Kuj tseem muaj kev saib xyuas thiab kev mob hnyav, vim tias kev tsis saib xyuas me me hauv kev tsim kho vajtse feem ntau tuaj yeem ua rau poob nyiaj txiag loj heev. Piv txwv li, thaum lub rooj tsavxwm tsim thiab tsim cov ntaub ntawv ua tiav ua ntej, qhov kev ua haujlwm tsis zoo ua rau lub zog txheej thiab txheej hauv av txuas nrog. Nyob rau tib lub sijhawm, tom qab lub rooj tsavxwm PCB tau tsim, nws tau ncaj qha mus rau ntawm cov kab ntau lawm yam tsis muaj kev tshuaj xyuas. Nws tsuas yog thaum lub sijhawm kuaj pom tias qhov teeb meem luv luv tau pom, tab sis cov khoom siv tau raug soldered rau lub rooj tsavxwm, ua rau ntau pua txhiab tus poob. Yog li ntawd, ua tib zoo xyuas thiab ua tib zoo tshuaj xyuas, kev kuaj xyuas lub luag haujlwm, thiab kev kawm tsis tu ncua thiab kev sib sau ua ke tuaj yeem ua rau tus neeg tsim khoom kho vajtse ua kom muaj kev vam meej, thiab tom qab ntawd ua qee qhov kev ua tiav hauv kev lag luam.
