1. Xaiv cov phiaj xwm tseeb tau teeb tsa thiab ib txwm siv cov phiaj xwm plia uas sib tw feem ntau cov khoom siv. Txawm hais tias kev coj ua ntawm ntau daim phiaj zoo li tseem ceeb heev, yog tias lawv tuaj yeem zam qhov nyuaj ntawm kev ncua sijhawm thiab ua kom tiav daim ntawv thov ntawm PCB. Vim tias muaj ntau cov khoom siv siv ntau lub pob ntau thiab tsawg, cov kws ua choj yuav tsum siv cov khoom lag luam uas tau txais txiaj ntsig zoo tshaj plaws rau lawv tus kheej. Ib qho ntxiv, polygons yog qhov tseem ceeb heev rau tooj liab plating ntawm Circuit Court boards. Polygon puv kev sib txawv feem ntau tshwm sim thaum Polygon Tooj Liab plating yog nqa tawm ntawm ntau-Gate Circuit Court boards. Txawm hais tias nws tsis yog raws li ib tus qauv fais fab nyiaj, nws tuaj yeem muab kev pabcuam uas tshaj li cov kev pabcuam xav tau ntawm Circuit Board.
2. Ua kom txoj kev luv tshaj thiab tshaj plaws. Qhov no suab yooj yim thiab muaj ntau, tab sis nws yuav tsum tau ceev cia rau txhua theem, txawm tias nws txhais tau tias hloov cov txheej txheem ntawm cov txheej txheem Circuit Court los ua kom muaj kev ua haujlwm zoo. Qhov no yog qhov tshwj xeeb tshaj yog haum rau analog thiab high-ceev cov kev ua nrawm nrawm, thiab nws cov kev ua tau zoo yog ib txwm muaj kev cuam tshuam nrog kev cuam tshuam thiab kev cuam tshuam parasitic.
3. Siv lub zog txheej los tswj kev faib cov hluav taws xob cov kab thiab cov kab hauv av kom ntau li ntau tau. Rau feem ntau pcb tsim software, tooj liab txheej ntawm lub zog txheej yog qhov kev xaiv nrawm dua thiab yooj yim dua. Los ntawm kev sib qhia ntau ntawm cov xov hlau, nws tuaj yeem ntseeg tau tias qhov tam sim no nrog lub siab loj tshaj plaws, qhov kev poob siab tshaj plaws yog muab, thiab ib lub voj pua av uas txaus. Yog tias ua tau, ntau txoj kab hluav taws xob kuj tseem tuaj yeem ua haujlwm hauv tib qho chaw ntawm cov txheej txheem pcb kom paub meej tias feem ntau ntawm cov pcb txheej, uas muaj txiaj ntsig zoo rau cov kev ua haujlwm ntawm cov kab ua haujlwm nyob ib sab.
4. Ua ke cov feem cuam tshuam nrog cov ntsiab lus kev ntsuam xyuas uas yuav tsum tau ua. Piv txwv li, cov ntsiab lus txiav txim siab yuav tsum tau muab tso rau ze rau lawv kom ua haujlwm tau ua rau lawv xav tau, yog li kev ua haujlwm tau ua kom tau txais txoj cai 2 thiab ua kev sim siab thiab ua txhaum kev txiav txim siab yooj yim dua.
5. Luam Circuit Court Board ob peb zaug ntawm lwm cov Board Loj Board rau PCB los ua ke. Xaiv qhov kev tsim nyog tshaj plaws ntawm cov khoom siv siv los ntawm cov chaw tsim khoom yog pab tau kom txo tus nqi ntawm cov qauv tsim qauv thiab tsim khoom. Ua ntej tshaj plaws, npaj cov pob zeb hauv Circuit Cours rau ntawm cov vaj tse, hu rau cov qauv tsim qauv loj ntawm txhua lub sijhawm nyob hauv pawg vaj huam sib luag.
6. Kev sib xyaw ua ke cov txiaj ntsig. Raws li tus tsim qauv, koj yuav xaiv qee cov khoom sib txawv nrog cov khoom siv muaj txiaj ntsig lossis qis dua qhov tseem ceeb tab sis zoo ib yam. Los ntawm kev sib xyaw ua ke nyob rau hauv thaj tsam tsawg ntawm cov qauv txheem muaj nuj nqis, cov ntaub ntawv ntawm cov ntaub ntawv tuaj yeem ua kom yooj yim thiab tus nqi tuaj yeem txo. Yog tias koj muaj cov khoom lag luam pcb ntawm cov khoom siv uas nyiam tshaj plaws, nws yuav muaj txiaj ntsig zoo rau koj los ua cov kev txiav txim siab tsim nyog tswj hwm hauv lub sijhawm ntev.
7. Ua raws li ntau cov qauv kev kuaj xyuas (DRC) li sai tau. Txawm hais tias nws tsuas yog lub sijhawm luv luv los khiav DRC muaj nuj nqi ntawm ib puag ncig PCB, ntev npaum li cov txheej txheem tsim, muaj ntau lub sijhawm tuaj yeem tau txais kev tswj hwm zoo. Txhua txoj kev txiav txim siab yog qhov tseem ceeb heev, thiab siv DRC tuaj yeem ua kom koj xaiv txoj hauv kev tseem ceeb tshaj plaws txhua lub sijhawm.
8. Kev siv cov vijtsam luam ntawv. Tus kws tshuaj ntsuam luam tawm tuaj yeem siv los khij txhua yam ntaub ntawv muaj txiaj ntsig rau kev siv hluav taws xob, kev pabcuam lossis cov kws tshaj lij lossis khoom siv debugging. Not only should the function and test point labels be clearly marked, but also the orientation of components and connectors should be marked as much as possible, even if these notes are printed on the lower surface of components used on the circuit board (after the circuit board is assembled). Daim Ntawv Thov Kev Tshuaj Ntsuam Tag Nrho Ntawm Cov Ntsuam Xyuas Tshuab rau ntawm cov chaw sab saud thiab qis dua ntawm cov cam circuit Court tuaj yeem txo cov txheej txheem ua kom rov ua haujlwm thiab ua rau cov txheej txheem ntau lawm.
9. Decoupling capacitors xav tau. Tsis txhob sim ua kom zoo dua tus qauv tsim los ntawm kev zam cov kab hluav taws xob decoupling thiab raws li cov kev txwv hauv cov ntaub ntawv cov ntaub ntawv tiv thaiv. Peev yog qhov pheej yig thiab ruaj. Koj tuaj yeem siv sijhawm ntau li ntau tau raws li cov rooj sib tham capacitors. Nyob rau tib lub sijhawm, ua raws txoj cai 6 thiab siv tus qauv txheem muaj nuj nqis ntau los khaws cov khoom lus kom huv.
10. Tsim cov PCB tsim cov khoom tsis thiab xyuas lawv ua ntej xa lawv rau ntau lawm. Txawm hais tias feem ntau Circuit Court board cov tuam txhab tsim kev lag luam zoo siab los rub tawm thiab tshawb xyuas cov ntaub ntawv Gerber ua ntej thiab kuaj xyuas cov kev cia siab nrog kev zam txim. Los ntawm tus kheej kev txheeb xyuas tus kheej, koj yuav txawm pom qee qhov kev ua yuam kev tsis saib xyuas kom zam dhau qhov kev poob los ntawm kev ua tiav cov khoom siv raws li cov tsis ncaj ncees lawm.
