Lub Zog PCB txheej thiab protel qhov zoo sib xws thiab sib txawv

Ntau ntawm peb cov qauv siv ntau dua ib qho software. Vim tias protel tau yooj yim los pib, ntau tus phooj ywg kawm protel ua ntej thiab tom qab ntawd Fais Fab. Tau kawg, ntau ntawm lawv kawm Fais Fab ncaj qha, thiab qee qhov siv ob lub software ua ke. Txij li ob lub software muaj qee qhov sib txawv hauv txheej Chaw, cov pib tshiab tuaj yeem yooj yim tsis meej pem, yog li cia peb sib piv lawv ib sab. Cov uas kawm lub hwj chim ncaj qha kuj tuaj yeem saib nws kom muaj qhov siv tau.

Ua ntej saib cov qauv kev faib tawm ntawm txheej sab hauv

Software lub npe Tus Cwj Pwm Txheej npe lub npe siv

PROTEL: Zoo MIDLAYER Cov kab ntshiab kab

MIDLAYER Hybrid hluav taws xob txheej (suav nrog thaiv, tawv tooj liab loj)

Ntshiab tsis zoo (tsis muaj kev faib, piv txwv li GND)

INTERNAL Sawb INTERNAL faib (feem ntau muaj teeb meem ntau lub zog)

Hwj chim: zoo TSIS MUAJ PLANE Cov kab ntshiab kab

TSIS MUAJ TSEEB Cov txheej hluav taws xob sib xyaw (siv txoj kev COPPER POUR)

SPLIT/MIXED txheej hluav taws xob (txheej txheej txheej SPLIT txheej txheej)

Ntshiab tsis zoo zaj duab xis (tsis muab faib, piv txwv li GND)

Raws li pom los ntawm daim duab saum toj no, cov hluav taws xob txheej ntawm POWER thiab PROTEL tuaj yeem faib ua qhov zoo thiab qhov tsis zoo, tab sis cov txheej txheej muaj nyob hauv ob txheej txheej no sib txawv.

1.PROTEL tsuas muaj ob txheej txheej, sib thooj rau tus yam ntxwv zoo thiab tsis zoo ib feem. Txawm li cas los xij, POWER txawv. Cov yeeb yaj kiab zoo hauv POWER tau muab faib ua ob hom, NO PLANE thiab SPLIT/MIXED

2. Cov yeeb yaj kiab tsis zoo hauv PROTEL tuaj yeem faib los ntawm txheej hluav taws xob sab hauv, thaum cov yeeb yaj kiab tsis zoo hauv POWER tuaj yeem tsuas yog cov yeeb yaj kiab tsis zoo (txheej hluav taws xob sab hauv tsis tuaj yeem faib ua ntu, uas yog qis dua PROTEL). Sab hauv segmentation yuav tsum ua tiav siv qhov zoo. Nrog SPLIT/MIXED txheej, koj kuj tseem tuaj yeem siv qhov zoo ib yam (TSIS YOG)+ tooj liab.

Qhov ntawd yog hais, hauv POWER PCB, txawm hais tias siv rau POWER txheej txheej txheej lossis MIXED cov txheej hluav taws xob, yuav tsum siv qhov zoo, thiab qhov zoo ib yam (Tsis muaj phiaj xwm) thiab tshwj xeeb MIXED hluav taws xob txheej (SPLIT/MIXED) qhov sib txawv tsuas yog txoj hauv kev tso tooj liab tsis zoo ib yam! Qhov tsis zoo tuaj yeem tsuas yog ib qho tsis zoo. (Nws tsis pom zoo siv 2D LINE los faib cov yeeb yaj kiab tsis zoo vim tias nws nquag ua yuam kev vim tsis muaj kev sib txuas hauv network thiab tsim cov cai.)

Cov no yog qhov sib txawv tseem ceeb ntawm txheej Chaw thiab txheej sab hauv.

Qhov sib txawv ntawm SPLIT/MIXED txheej txheej sab hauv SPLIT thiab TSIS PLANE txheej txheej tooj liab

1.SPLIT/MIXED: PLACE AREA cov lus txib yuav tsum tau siv, uas tuaj yeem tshem tawm sab hauv lub ncoo ywj pheej thiab tuaj yeem siv rau thaiv. Lwm cov tes hauj lwm tuaj yeem faib tau yooj yim ntawm daim tawv nqaij tooj liab loj.

2.NO PLANEC txheej: COPPER POUR yuav tsum siv, uas zoo ib yam li cov kab sab nrauv. Cov ntaub qhwv ywj pheej yuav tsis raug txiav tawm. Ntawd yog hais, qhov tshwm sim ntawm cov tawv nqaij tooj liab loj nyob ib puag ncig daim tawv nqaij tooj liab tsis tuaj yeem tshwm sim.

POWER PCB txheej txheej thiab txheej txheej txheej txheej

Tom qab saib cov qauv duab saum toj no, koj yuav tsum muaj lub tswv yim zoo ntawm txheej txheej ntawm POWER. Tam sim no koj tau txiav txim siab tias yuav siv txheej dab tsi los ua kom tiav cov qauv, cov kauj ruam tom ntej yog ntxiv cov txheej hluav taws xob.

Ua ib pawg plaub-txheej ua piv txwv:

Ua ntej, tsim qhov tsim qauv tshiab, ntshuam cov npe hauv net, ua tiav cov txheej txheem yooj yim, thiab tom qab ntawd ntxiv LAYER teeb-Txheej DEFINITION. Hauv ELECTRICAL LAYER cheeb tsam, nyem qhov hloov pauv, thiab sau 4, OK, OK hauv lub qhov rai qhib. Tam sim no koj muaj ob txheej hluav taws xob tshiab ntawm TOP thiab BOT. Npe ob txheej thiab teeb hom txheej.

INNER LAYER2 npe nws GND thiab teeb nws rau CAM PLANE. Tom qab ntawv nyem rau ntawm sab xis ntawm ASSIGN network. Cov txheej no yog tag nrho cov tawv nqaij tooj liab ntawm cov yeeb yaj kiab tsis zoo, yog li ASSIGN ib GND.

Npe INNER LAYER3 POWER thiab teeb nws rau SPLIT/MIXED (vim tias muaj ntau pawg POWER muab khoom, yog li INNER SPLIT yuav siv), nyem ASSIGN thiab ASSIGN POWER network uas xav tau los ntawm INNER txheej mus rau ASSOCIATED qhov rai ntawm sab xis (piv txwv tias peb lub hwj chim muab cov tes hauj lwm sib faib).

Cov kauj ruam tom ntej rau thaiv, kab sab nrauv ntxiv rau lub zog hluav taws xob sab nraum txhua qhov mus. POWER network tau txuas ncaj qha mus rau txheej txheej ntawm lub qhov tuaj yeem txuas nrog tau yooj yim (cov txuj ci me, thawj zaug piav qhia hom POWER txheej CAM PLANE, yog li txhua qhov faib rau txheej sab hauv ntawm POWER network thiab cov kab kab yuav xav uas tau txuas nrog, thiab cia li tshem tawm cov kab nas). Tom qab tag nrho cov xov hlau tiav, txheej sab hauv tuaj yeem faib.

Thawj kauj ruam yog xim lub network kom paub qhov txawv ntawm qhov chaw ntawm kev sib cuag. Nias CTRL+SHIFT+N txhawm rau txheeb xyuas lub network xim (rho tawm).

Tom qab ntawd hloov cov txheej txheem txheej txheej ntawm POWER txheej rov qab rau SPLIT/MIXED, nyem DRAFTING-PLACE AREA, tom ntej kos tooj liab ntawm thawj POWER network.

Network 1 (daj): Thawj lub network yuav tsum npog tag nrho lub rooj tsavxwm thiab raug xaiv los ua lub network nrog thaj chaw sib txuas loj tshaj plaws thiab muaj kev sib txuas coob tshaj plaws.

Network # 2 (ntsuab): Tam sim no rau lub network thib ob, nco ntsoov tias vim lub network no nyob hauv nruab nrab ntawm pawg thawj coj, peb yuav txiav tawm lub network tshiab ntawm cov tooj liab loj uas twb tau muab tso lawm. Los yog nyem rau ntawm PLACE AREA, thiab tom qab ntawd ua raws cov lus qhia ntawm kev ua xim ntawm kev txiav AREA, thaum ob npaug nias qhov txiav, lub kaw lus yuav tshwm sim txiav los ntawm lub network tam sim no (1) thiab (2) AREA ntawm cov kab sib txuas tam sim no (vim tias nws tau txiav qhov tshwj xeeb ua rau txoj hauv kev tooj liab, yog li tsis tuaj yeem nyiam txiav qhov tsis zoo nrog txoj kab zoo kom ua tiav qhov loj tooj liab ntu ntu). Muab lub npe network ib yam nkaus.

Network 3 (red) : the third network below, since this network is closer to the board edge, we can also use another command to do it. Nyem kev tshaj lij -AUTO PLANE SEPARATE, kos duab los ntawm lub rooj tsavxwm ntug, npog cov neeg xav tau thiab tom qab ntawd rov qab mus rau ntawm lub rooj tsavxwm ntug, ob npaug nias kom ua tiav. Txoj siv cais tawm kuj tseem yuav tshwm sim thiab lub qhov rai faib network yuav tshwm sim. Nco ntsoov tias lub qhov rai no xav tau ob lub network sib faib ua ke, ib qho rau lub network koj tsuas yog txiav thiab ib qho rau thaj chaw seem (hais qhia).

Txij ntawm no mus, tag nrho txoj haujlwm ua haujlwm tau tiav lawm. Thaum kawg, POUR tus thawj tswj hwm-lub dav hlau CONNECT tau siv los sau tooj liab, thiab cov txiaj ntsig tuaj yeem pom.
