Nyob rau hauv tus txheej txheem ntawm PCB tsim, yog tias muaj kev pheej hmoo tuaj yeem kwv yees ua ntej thiab zam ua ntej, qhov ua tiav ntawm PCB tsim yuav zoo dua. Ntau lub tuam txhab ntsuas cov phiaj xwm nrog qhov ntsuas ntawm qhov ua tiav ntawm PCB tsim pawg thawj coj saib.

Qhov tseem ceeb txhawm rau txhim kho qhov ua tiav ntawm pawg thawj coj yog teeb tsa kev tsim qauv ncaj ncees. Hauv kev tsim cov txheej txheem hluav taws xob tam sim no, muaj ntau cov phiaj xwm khoom lag luam, cov tuam txhab tsim khoom lag luam tau ua tiav, suav nrog dab tsi yog siv chip, yuav ua li cas tsim cov khoom siv hluav taws xob ib leeg thiab lwm yam. Feem ntau, cov kws kho vajtse kho vajtse yuav tsum xav txog qhov teeb meem ntawm txoj cai hauv Circuit, tsuas yog xav tau los ua lawv tus kheej PCB.

Txawm li cas los xij, nws nyob hauv txheej txheem PCB tsim uas ntau lub tuam txhab ntsib teeb meem, txawm tias PCB tsim tsis ruaj khov, lossis tsis ua haujlwm. Rau cov lag luam loj, ntau lub tuam txhab tsim khoom lag luam yuav muab kev txhawb nqa thiab kev qhia ntawm PCB tsim. Tab sis qee qhov kev lag luam me thiab nruab nrab muaj teeb meem nyuaj tau txais kev txhawb nqa zoo li no. Yog li, koj yuav tsum nrhiav txoj hauv kev los ua koj tus kheej, uas ua rau muaj teeb meem ntau, uas yuav xav tau ob peb tsab ntawv thiab siv sijhawm ntev ntawm kev debugging. Qhov tseeb, yog tias koj nkag siab cov qauv tsim ntawm cov kab ke, qhov no tuaj yeem zam tau. Here are three tips for reducing PCB design risk.

1, the system planning stage is best to consider the problem of signal integrity, the whole system is built like this, the signal from one PCB to another PCB can receive correctly? Qhov no yuav tsum tau ntsuas nyob rau theem pib, thiab nws tsis nyuaj rau ntsuas qhov teeb meem. Kev paub me ntsis ntawm lub teeb liab ncaj ncees thiab ob peb txoj haujlwm yooj yim software tuaj yeem ua nws.

Second, in the PCB design process, the use of simulation software to evaluate the specific wiring, observe whether the signal quality can meet the requirements, the simulation process itself is very simple, the key is to understand the principle of signal integrity knowledge, and used for guidance.

Third, in the process of PCB, we must carry out risk control. Muaj ntau qhov teeb meem, simulation software tsis muaj txoj hauv kev los daws, yuav tsum tau tswj los ntawm tus tsim qauv. Tus yuam sij rau cov kauj ruam no yog nkag siab qhov kev pheej hmoo nyob qhov twg thiab yuav ua li cas thiaj zam tau lawv, dua nrog kev paub txog teeb liab kev ntseeg.

Yog tias peb lub ntsiab lus tuaj yeem nkag siab tau zoo hauv PCB txheej txheem tsim, tom qab ntawd PCB tsim kev pheej hmoo yuav raug txo qis, qhov tshwm sim ntawm qhov ua yuam kev yuav me dua tom qab pawg thawj coj tau thim rov qab, thiab kev debugging yuav yooj yim dua.
