PCB tsim
Software
1. Feem ntau siv software nyob rau hauv Suav teb yog Protel, Protel 99se, Protel DXP, Altium, lawv yog los ntawm tib lub tuam txhab thiab hloov kho tas li;cov qauv tam sim no yog Altium Designer 15 uas yog qhov yooj yim, tus qauv tsim yog ntau yam xws li, tab sis tsis zoo heev rau cov PCBs nyuaj.
2. Cadence SPB.Tam sim no version yog Cadence SPB 16.5;ORCAD schematic tsim yog tus qauv thoob ntiaj teb;PCB tsim thiab simulation yog tiav heev.Nws yog qhov nyuaj rau siv ntau dua li Protel.Cov kev cai tseem ceeb yog nyob rau hauv cov teeb meem nyuaj.;Tab sis muaj cov cai rau kev tsim qauv, yog li tus qauv tsim muaj txiaj ntsig zoo dua, thiab nws muaj zog dua Protel.
3. Tus cob qhia BORDSTATIONG thiab EE, BOARDSTATION tsuas yog siv tau rau UNIX system, tsis tsim rau PC, yog li cov neeg siv tsawg dua;Tam sim no Mentor EE version yog Mentor EE 7.9, nws yog nyob rau tib theem nrog Cadence SPB, nws lub zog yog rub hlau thiab ya hlau.Nws yog hu ua ib tug ya hlau huab tais.
4. EAGLE.Qhov no yog qhov siv ntau tshaj plaws PCB tsim software hauv Europe.PCB tsim software tau hais los saum no yog siv ntau heev.Cadence SPB thiab Mentor EE yog cov vajntxwv zoo tsim nyog.Yog tias nws yog tus pib tsim PCB, Kuv xav tias Cadence SPB zoo dua, nws tuaj yeem tsim tus cwj pwm zoo rau tus tsim qauv, thiab tuaj yeem ua kom zoo tsim qauv zoo.
Kev txawj ntse
Teeb tsa cov lus qhia
Tus tsim yuav tsum tau teem rau ntau lub ntsiab lus nyob rau hauv ntau theem.Nyob rau hauv lub layout theem, cov ntsiab lus kab sib chaws loj tuaj yeem siv rau cov cuab yeej layout;
Rau cov khoom siv loj xws li ICs thiab cov khoom sib txuas tsis yog qhov chaw, koj tuaj yeem xaiv qhov tseeb ntawm kab sib chaws ntawm 50 mus rau 100 mils rau kev teeb tsa.Rau cov khoom siv me me xws li resistors, capacitors, thiab inductors, koj tuaj yeem siv 25 mils rau kev teeb tsa.Qhov tseeb ntawm cov kab sib chaws loj cov ntsiab lus yog qhov tsim nyog rau kev sib tw ntawm cov cuab yeej thiab kev zoo nkauj ntawm qhov layout.
PCB layout txoj cai:
1. Nyob rau hauv ib txwm muaj xwm txheej, tag nrho cov khoom yuav tsum tau muab tso rau ntawm tib qhov chaw ntawm lub rooj tsav xwm Circuit Court.Tsuas yog thaum cov txheej txheem saum toj kawg nkaus yog tuab heev, tuaj yeem muaj qee qhov kev txwv siab thiab qis qis, xws li nti resistors, nti capacitors, muab tshuaj txhuam Chip ICs muab tso rau hauv qab txheej.
2. Nyob rau ntawm qhov chaw ntawm kev ua kom muaj hluav taws xob ua haujlwm, cov khoom siv yuav tsum tau muab tso rau ntawm daim phiaj thiab teem caij sib dhos los yog sib dhos rau ib leeg kom zoo nkauj thiab zoo nkauj.Raws li ib txwm muaj, cov khoom tsis raug tso cai sib tshooj;cov Cheebtsam yuav tsum tau teem compactly, thiab cov Cheebtsam yuav tsum nyob rau hauv tag nrho cov layout Uniform faib thiab uniform ntom.
3. Qhov tsawg kawg nkaus qhov sib nrug ntawm qhov sib txuas ntawm cov qauv ntawm cov khoom sib txawv ntawm lub rooj tsav xwm Circuit Court yuav tsum siab tshaj 1MM.
4. Nws yog feem ntau tsis pub tsawg tshaj 2MM deb ntawm ntug ntawm lub rooj tsavxwm.Qhov zoo tshaj plaws zoo ntawm lub rooj tsavxwm Circuit Court yog cov duab plaub, nrog qhov ntev mus rau qhov dav ntawm 3: 2 lossis 4: 3. Thaum lub rooj tsavxwm loj dua 200MM los ntawm 150MM, kev them taus ntawm lub rooj tsavxwm Circuit Court yuav tsum suav tias yog lub zog ntawm lub zog.
Kev txawj layout
Hauv kev tsim qauv ntawm PCB, chav tsev ntawm lub rooj tsav xwm hauv Circuit Court yuav tsum tau soj ntsuam, kev tsim qauv tsim yuav tsum yog raws li kev ua haujlwm, thiab kev teeb tsa ntawm tag nrho cov khoom hauv Circuit Court yuav tsum ua raws li cov hauv qab no:
1. Npaj txoj hauj lwm ntawm txhua qhov kev ua haujlwm hauv Circuit Court raws li qhov ntws ntawm lub voj voog, ua kom cov txheej txheem yooj yim rau cov teeb liab ncig, thiab khaws cov teeb liab nyob rau hauv tib txoj kev raws li qhov ua tau.
2. Nrog rau cov ntsiab lus tseem ceeb ntawm txhua chav ua haujlwm ua qhov chaw, layout nyob ib ncig ntawm nws.Cov Cheebtsam yuav tsum sib npaug, sib xyaw ua ke thiab sib sau ua ke ntawm PCB kom txo qis thiab txo cov kev coj ua thiab kev sib txuas ntawm cov khoom.
3. Rau cov khoom siv hluav taws xob ua haujlwm ntawm cov khoom siv hluav taws xob siab, qhov kev faib tawm ntawm cov khoom yuav tsum raug txiav txim siab.Lub voj voog dav dav yuav tsum npaj cov khoom sib luag kom ntau li ntau tau, uas tsis yog tsuas yog zoo nkauj, tab sis kuj yooj yim rau nruab thiab solder, thiab yooj yim rau cov khoom loj.
Tsim cov kauj ruam
Layout tsim
Hauv PCB, cov khoom tshwj xeeb xa mus rau cov khoom tseem ceeb hauv qhov siab zaus, cov ntsiab lus tseem ceeb hauv Circuit Court, cov khoom siv yooj yim cuam tshuam, cov khoom siv hluav taws xob siab, cov khoom siv hluav taws xob loj, thiab qee cov khoom sib txawv. Qhov chaw ntawm cov khoom tshwj xeeb no yuav tsum tau ua tib zoo txheeb xyuas, thiab cov txheej txheem yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua hauv Circuit Court thiab kev tsim khoom.Kev tso kawm tsis raug ntawm lawv yuav ua rau muaj teeb meem kev sib raug zoo hauv Circuit Court thiab teeb liab teeb meem kev ncaj ncees, uas tuaj yeem ua rau tsis ua haujlwm ntawm PCB tsim.
Thaum muab cov khoom tshwj xeeb hauv kev tsim, ua ntej xav txog PCB loj.Thaum lub PCB loj dhau lawm, cov kab luam tawm ntev, qhov impedance nce, lub peev xwm los tiv thaiv kom qhuav, thiab tus nqi kuj nce ntxiv;yog tias nws me dhau lawm, qhov cua sov dissipation tsis zoo, thiab cov kab uas nyob ib sab yooj yim cuam tshuam.Tom qab txiav txim siab qhov loj ntawm PCB, txiav txim siab lub pendulum txoj hauj lwm ntawm cov khoom tshwj xeeb.Thaum kawg, raws li kev ua haujlwm, tag nrho cov khoom siv hauv Circuit Court tau muab tso rau.Qhov chaw ntawm cov khoom tshwj xeeb feem ntau yuav tsum ua raws li cov hauv qab no thaum lub sij hawm layout:
1. Txo qhov kev sib txuas ntawm cov khoom siv hluav taws xob ntau ntau li ntau tau, sim txo lawv cov kev faib tawm thiab kev cuam tshuam ntawm electromagnetic cuam tshuam.Cov khoom raug cuam tshuam tsis tuaj yeem nyob ze rau ib leeg, thiab cov tswv yim thiab cov zis yuav tsum nyob deb li deb tau.
2 Qee cov khoom siv lossis cov xov hlau yuav muaj qhov sib txawv ntau dua, thiab lawv qhov kev ncua deb yuav tsum tau nce ntxiv kom tsis txhob muaj kev sib tsoo luv luv los ntawm kev tso tawm.Cov khoom siv hluav taws xob high-voltage yuav tsum tsis txhob ncav cuag.
3. Cov khoom hnyav tshaj 15G tuaj yeem kho nrog cov hlua khi thiab tom qab ntawd welded.Cov khoom hnyav thiab kub yuav tsum tsis txhob muab tso rau ntawm lub rooj tsav xwm hauv Circuit Court tab sis yuav tsum tau muab tso rau hauv qab phaj ntawm lub chassis tseem ceeb, thiab cov cua kub yuav tsum tau xav txog.Thermal Cheebtsam yuav tsum khaws cia kom deb ntawm cov khoom cua sov.
4. Cov txheej txheem ntawm cov khoom hloov kho xws li potentiometer, adjustable inductance coils, hloov pauv capacitors, micro keyboards, thiab lwm yam yuav tsum xav txog cov txheej txheem ntawm tag nrho lub rooj tsavxwm.Qee cov keyboards nquag siv yuav tsum muab tso rau qhov twg koj tuaj yeem ncav cuag nws nrog koj txhais tes yooj yim.Cov txheej txheem ntawm cov cheebtsam yog sib npaug, ntom thiab ntom, tsis yog saum-hnyav.
Ib qho kev vam meej ntawm cov khoom lag luam yog them nyiaj rau sab hauv zoo.Tab sis nws yog ib qho tsim nyog yuav tsum coj mus rau hauv tus account tag nrho kev zoo nkauj, ob qho tib si yog cov laug cam zoo meej, thiaj li ua tiav cov khoom lag luam.
Ib ntus
1. Muab cov khoom sib xyaw ua ke zoo sib xws, xws li lub qhov hluav taws xob, qhov taw qhia teeb, cov keyboards, connectors, thiab lwm yam.
2. Muab cov khoom tshwj xeeb, xws li cov khoom loj, cov khoom hnyav, cov khoom siv cua sov, cov transformers, ICs, thiab lwm yam.
3. Muab cov khoom me me.
layout check
1. Seb qhov luaj li cas ntawm lub rooj tsav xwm Circuit Court thiab cov duab kos ua tau raws li qhov ua tiav.
2. Seb lub layout ntawm lub Cheebtsam yog sib npaug, zoo zoo, thiab seb lawv tag nrho cov tau nteg tawm.
3. Puas muaj kev tsis sib haum xeeb ntawm txhua theem?Xws li seb cov khoom siv, cov txheej txheem sab nrauv, thiab qib uas xav tau kev luam ntawv ntiag tug yog qhov tsim nyog.
3. Txawm hais tias cov khoom siv feem ntau siv tau yooj yim.Xws li cov keyboards, plug-in boards tso rau hauv cov khoom siv, cov khoom uas yuav tsum tau hloov ntau zaus, thiab lwm yam.
4. Puas yog qhov kev ncua deb ntawm cov khoom siv thermal thiab cov khoom cua sov puas tsim nyog?
5. Txawm tias cov cua kub dissipation zoo.
6. Seb qhov teeb meem ntawm kab cuam tshuam yuav tsum tau xav txog.
