Qhov ua tiav PCB peb pom yog feem ntau yog cov duab plaub.Txawm hais tias feem ntau cov qauv tsim yog cov duab plaub tiag tiag, ntau cov qauv tsim yuav tsum tsis tu ncua zoo li lub rooj tsavxwm, thiab cov duab zoo li no feem ntau tsis yooj yim rau kev tsim.Kab lus no piav qhia txog yuav ua li cas tsim cov PCBs tsis zoo.

Niaj hnub no, qhov luaj li cas ntawm PCB yog tas li shrinking, thiab cov dej num nyob rau hauv lub Circuit Court board kuj nce.Ua ke nrog kev nce ntawm lub moos ceev, tus qauv tsim ua ntau dua thiab nyuaj.Yog li, cia peb saib yuav ua li cas nrog cov rooj sib tham hauv Circuit Court nrog cov duab ntau dua.

Raws li pom hauv daim duab 1, ib qho yooj yim PCI board zoo tuaj yeem tsim tau yooj yim hauv EDA Layout cov cuab yeej feem ntau.

Txawm li cas los xij, thaum lub rooj tsav xwm lub rooj tsav xwm yuav tsum tau hloov mus rau qhov chaw kaw nrog qhov siab txwv, nws tsis yooj yim rau cov neeg tsim qauv PCB, vim tias cov haujlwm hauv cov cuab yeej no tsis zoo ib yam li cov tshuab CAD.Lub complex Circuit Board tau pom nyob rau hauv daim duab 2 yog tsuas yog siv nyob rau hauv tawg-pov thawj enclosures thiab yog li raug rau ntau yam kev txwv.Kev tsim kho cov ntaub ntawv no hauv EDA cov cuab yeej yuav siv sij hawm ntev thiab tsis muaj txiaj ntsig.Vim hais tias, cov neeg kho tshuab engineers zoo li yuav tau tsim cov ntaub thaiv npog, lub rooj tsav xwm hauv Circuit Court, qhov chaw qhov chaw, thiab qhov siab txwv qhov yuav tsum tau ua los ntawm PCB tus tsim.

Vim lub arc thiab vojvoog nyob rau hauv lub rooj tsavxwm Circuit Court, lub sij hawm reconstruction yuav ntev tshaj li qhov xav tau txawm tias lub Circuit Court board zoo tsis nyuaj (raws li qhia hauv daim duab 3).

Cov no tsuas yog ob peb yam piv txwv ntawm complex circuit board duab.Txawm li cas los xij, los ntawm cov neeg siv khoom siv hluav taws xob niaj hnub no, koj yuav xav tsis thoob thaum pom tias muaj ntau txoj haujlwm sim ntxiv tag nrho cov haujlwm hauv ib pob me me, thiab cov pob no tsis yog ib qho duab plaub.Koj yuav tsum xav txog smartphones thiab ntsiav tshuaj ua ntej, tab sis muaj ntau yam piv txwv zoo sib xws.

Yog tias koj xa rov qab lub tsheb xauj tsev, koj tuaj yeem pom tus neeg tos nyeem cov ntaub ntawv tsheb nrog lub xov tooj ntawm tes, thiab tom qab ntawd txuas lus nrog lub chaw ua haujlwm wirelessly.Cov cuab yeej tseem txuas nrog lub tshuab luam ntawv thermal rau kev luam ntawv sai sai.Qhov tseeb, tag nrho cov khoom siv no siv lub rooj tsav xwm nruj / hloov tau yooj yim (Daim duab 4), qhov twg PCB cov rooj sib tham ib txwm muaj cuam tshuam nrog cov ntawv luam tawm yooj yim kom lawv tuaj yeem muab tais rau hauv qhov chaw me me.

Tom qab ntawd, lo lus nug yog "Yuav ua li cas import cov txheej txheem kev tsim kho tshuab ua haujlwm rau hauv PCB tsim cov cuab yeej?"Kev rov siv cov ntaub ntawv no hauv kev kos duab kos duab tuaj yeem tshem tawm kev ua haujlwm duplicate, thiab tseem ceeb tshaj, tshem tawm tib neeg yuam kev.

Peb tuaj yeem siv DXF, IDF lossis ProSTEP hom ntawv los import tag nrho cov ntaub ntawv rau hauv PCB Layout software los daws qhov teeb meem no.Ua li ntawd tuaj yeem txuag tau ntau lub sijhawm thiab tshem tawm tib neeg kev ua yuam kev.Tom ntej no, peb yuav kawm txog cov qauv no ib los ntawm ib qho.

DXF yog hom qub tshaj plaws thiab siv dav tshaj plaws, uas feem ntau sib pauv cov ntaub ntawv ntawm cov tshuab thiab PCB tsim cov khoom siv hluav taws xob.AutoCAD tau tsim nws thaum xyoo 1980s.Hom ntawv no tsuas yog siv rau kev sib pauv ntaub ntawv ob sab.Feem ntau PCB cov neeg muag khoom txhawb nqa hom ntawv no, thiab nws ua kom yooj yim hloov cov ntaub ntawv.DXF ntshuam / xa tawm yuav tsum tau ua haujlwm ntxiv los tswj cov txheej txheem, cov chaw sib txawv thiab cov chav nyob uas yuav siv rau hauv cov txheej txheem sib pauv.Daim duab 5 yog ib qho piv txwv ntawm kev siv Mentor Graphics 'PADS cov cuab yeej los import ib lub rooj tsav xwm nyuaj heev hauv DXF hom:

Ob peb xyoos dhau los, 3D kev ua haujlwm tau pib tshwm sim hauv PCB cov cuab yeej, yog li xav tau ib hom ntawv uas tuaj yeem hloov cov ntaub ntawv 3D ntawm cov tshuab thiab cov cuab yeej PCB.Raws li qhov tshwm sim, Mentor Graphics tau tsim IDF hom ntawv, uas tau siv dav los hloov lub rooj tsav xwm thiab cov ntaub ntawv ntawm PCBs thiab cov cuab yeej siv tshuab.

Txawm hais tias hom ntawv DXF suav nrog lub rooj tsavxwm loj thiab tuab, IDF hom siv X thiab Y txoj haujlwm ntawm cov khoom siv, tus lej tivthaiv, thiab Z-axis qhov siab ntawm cov khoom.Hom ntawv no zoo heev txhim kho lub peev xwm pom PCB hauv kev pom peb sab.Cov ntaub ntawv IDF kuj tseem tuaj yeem suav nrog lwm cov ntaub ntawv hais txog thaj chaw txwv, xws li kev txwv qhov siab nyob rau sab saum toj thiab hauv qab ntawm lub rooj tsavxwm.

Lub kaw lus yuav tsum muaj peev xwm tswj tau cov ntsiab lus muaj nyob hauv IDF cov ntaub ntawv zoo ib yam li DXF parameter teeb tsa, raws li pom hauv daim duab 6. Yog tias qee cov khoom tsis muaj cov ntaub ntawv siab, IDF export tuaj yeem ntxiv cov ntaub ntawv ploj thaum lub sijhawm tsim. txheej txheem.

Lwm qhov zoo dua ntawm IDF interface yog tias ob tog tuaj yeem txav cov khoom mus rau qhov chaw tshiab lossis hloov lub rooj tsavxwm, thiab tom qab ntawd tsim cov ntaub ntawv IDF sib txawv.Qhov tsis zoo ntawm txoj kev no yog tias tag nrho cov ntaub ntawv uas sawv cev rau lub rooj tsavxwm thiab cov khoom hloov pauv yuav tsum tau muab rov qab los, thiab qee zaum, nws yuav siv sij hawm ntev vim cov ntaub ntawv loj.Tsis tas li ntawd, nws yog qhov nyuaj los txiav txim siab seb qhov kev hloov pauv twg tau ua nrog cov ntaub ntawv IDF tshiab, tshwj xeeb tshaj yog nyob rau hauv cov rooj sib tham loj.IDF cov neeg siv thaum kawg tuaj yeem tsim cov ntawv sau los txiav txim siab cov kev hloov pauv no.

Txhawm rau kom xa cov ntaub ntawv 3D zoo dua, cov neeg tsim qauv tab tom nrhiav kev txhim kho, thiab STEP hom tau los ua.STEP hom tuaj yeem nthuav qhia lub rooj tsav xwm loj thiab cov txheej txheem kev teeb tsa, tab sis qhov tseem ceeb tshaj, cov khoom siv tsis yog ib qho yooj yim cov duab nrog tsuas yog qhov siab tus nqi.STEP cov qauv qauv muab cov ncauj lus kom ntxaws thiab nyuaj sawv cev ntawm cov khoom hauv daim ntawv peb sab.Ob lub rooj tsav xwm Circuit Court thiab cov ntaub ntawv tivthaiv tuaj yeem hloov pauv ntawm PCB thiab tshuab.Txawm li cas los xij, tseem tsis tau muaj txoj hauv kev los taug qab cov kev hloov pauv.

Txhawm rau txhim kho kev sib pauv ntawm STEP cov ntaub ntawv, peb tau qhia ProSTEP hom ntawv.Hom ntawv no tuaj yeem hloov pauv cov ntaub ntawv tib yam li IDF thiab STEP, thiab muaj kev txhim kho zoo-nws tuaj yeem taug qab cov kev hloov pauv, thiab nws tseem tuaj yeem muab lub peev xwm los ua haujlwm hauv cov txheej txheem qub ntawm cov kev kawm thiab tshuaj xyuas txhua qhov kev hloov pauv tom qab tsim lub hauv paus.Ntxiv nrog rau kev saib cov kev hloov pauv, PCB thiab cov kws kho tshuab hluav taws xob kuj tuaj yeem pom zoo tag nrho lossis ib tus neeg cov kev hloov pauv hauv layout thiab board shape modifications.Lawv tuaj yeem hais qhia qhov sib txawv ntawm pawg thawj coj saib lossis qhov chaw sib txuas.Qhov kev sib txuas lus txhim kho no tsim kom muaj ECO (Engineering Change Order) uas tsis tau muaj ua ntej ntawm ECAD thiab pab pawg neeg kho tshuab (Daim duab 7).

Niaj hnub no, feem ntau ECAD thiab mechanical CAD systems txhawb kev siv ProSTEP hom los txhim kho kev sib txuas lus, yog li txuag tau ntau lub sij hawm thiab txo cov nqi tsis raug uas tuaj yeem tshwm sim los ntawm cov txheej txheem electromechanical complex.Qhov tseem ceeb tshaj, cov engineers tuaj yeem tsim ib lub rooj sib tham sib txuas nrog cov kev txwv ntxiv, thiab tom qab ntawd xa cov ntaub ntawv no hauv tshuab hluav taws xob kom tsis txhob muaj ib tus neeg txhais lus yuam kev ntawm lub rooj tsavxwm loj, yog li txuag lub sijhawm.

Yog tias koj tsis tau siv cov DXF, IDF, STEP lossis ProSTEP cov ntaub ntawv tawm tswv yim los pauv cov ntaub ntawv, koj yuav tsum xyuas lawv cov kev siv.Xav txog kev siv cov ntaub ntawv hluav taws xob sib pauv no kom tsis txhob nkim sij hawm los tsim cov duab hluav taws xob sib txuas.
