Thawj: kev npaj.

Qhov no suav nrog kev npaj cov tsev qiv ntawv thiab cov duab. “Txhawm rau ua haujlwm tau zoo, yuav tsum xub ua kom nws lub cuab yeej zoo”, txhawm rau ua lub rooj tsavxwm zoo, ntxiv rau lub hauv paus ntsiab lus ntawm kev tsim qauv zoo, tab sis tseem kos tau zoo. Ua ntej PCB tsim, the component library of schematic SCH and the component library of PCB should be prepared first. Peotel cov tsev qiv ntawv tuaj yeem siv tau, tab sis feem ntau nws nyuaj rau nrhiav lub tsev qiv ntawv tsim nyog, nws yog qhov zoo tshaj los ua koj tus kheej lub tsev qiv ntawv raws li tus txheej txheem cov ntaub ntawv ntawm cov cuab yeej xaiv. Hauv txoj ntsiab cai, ua PCB cov tsev qiv ntawv ua ntej, thiab tom qab ntawd SCH cov tsev qiv ntawv tiv toj. PCB cov tsev qiv ntawv cov ntawv xav tau siab, nws cuam tshuam ncaj qha rau kev teeb tsa pawg thawj coj saib; SCH cov tsev qiv ntawv cov khoom siv yuav tsum tau xoob, tsuav yog them nyiaj rau lub ntsiab lus ntawm tus lej tus lej thiab kev sib raug zoo nrog PCB cov khoom. PS: Nco tseg cov pins zais hauv cov tsev qiv ntawv txheem. Tom qab ntawd yog cov qauv tsim, npaj ua PCB tsim.

Qhov thib ob: PCB tsim qauv.

Hauv cov kauj ruam no, raws li lub rooj tsav xwm hauv Circuit Court loj thiab qhov chaw ua haujlwm, PCB pawg thawj coj tau kos rau hauv PCB tsim ib puag ncig, thiab cov khoom sib txuas, cov nyees khawm/hloov, ntsia hlau qhov, sib dhos qhov thiab lwm yam tau muab tso raws li qhov xav tau. Thiab ua tib zoo txiav txim siab thiab txiav txim thaj chaw thaiv thiab thaj chaw tsis muaj kab (xws li ntau npaum li cas ntawm lub qhov ntsia hlau nyob ib puag ncig thaj tsam tsis thaiv).

Thib peb: PCB txheej txheem. Cov txheej txheem yog muab cov cuab yeej tso rau ntawm lub rooj tsavxwm. At this point, if all the preparatory work mentioned above is done, you can generate the Design- CreateNetlist on the schematic, and then import the network table Design- LoadNets on the PCB diagram. Pom cov cuab yeej hubbub ntawm tag nrho pawg, nruab nrab ntawm tus pin thiab ya kab txuas tam sim. Koj tuaj yeem tso tawm lub cuab yeej. Kev teeb tsa dav dav yog ua raws li cov hauv paus ntsiab lus hauv qab no:

How to draw PCB board in PCB design environment

(1). Raws li qhov hluav taws xob ua tau zoo muab faib, feem ntau muab faib ua: thaj tsam digital (uas yog, ntshai kev cuam tshuam, thiab cuam tshuam), thaj chaw sib piv sib piv

(ntshai kev cuam tshuam), thaj chaw tsav lub zog (cuam tshuam qhov chaw);

(2). Ua kom tiav tib txoj haujlwm ntawm Circuit, yuav tsum tau muab tso kom ze li sai tau, thiab kho cov khoom kom ntseeg tau tias yooj yim tshaj plaws kev sib txuas; At the same time, adjust the relative position between the functional blocks to make the connection between the functional blocks the most concise.
