Iyo yakazara PCB yatinofungidzira inowanzoita rectangular chimiro.Kunyangwe akawanda magadzirirwo ari rectangular, akawanda magadzirirwo anoda zvisina kurongeka edunhu mabhodhi, uye maumbirwo akadaro kazhinji haasi nyore kugadzira.Ichi chinyorwa chinotsanangura maitiro ekugadzira maPCB asina kurongeka.

Mazuva ano, ukuru hwePCB huri kuramba huchiderera, uye mabasa ari mubhodhi redunhu ari kuwedzerawo.Yakabatana nekuwedzera kwekumhanya kwewachi, dhizaini inowedzera uye yakaoma.Saka, ngatitarisei maitiro ekuita nemapuranga ematunhu ane mamwe maumbirwo akaoma.

Sezvinoratidzwa muMufananidzo 1, chimiro chakareruka chePCI board chinogona kugadzirwa zviri nyore mune akawanda EDA Layout maturusi.

Nekudaro, kana iyo dhizaini bhodhi chimiro inoda kuchinjirwa kune yakaoma yakavharwa nekukwirira kurambidzwa, hazvisi nyore kune vanogadzira PCB, nekuti mabasa ari mumidziyo iyi haana kufanana neaya emakanika CAD masisitimu.Iyo yakaoma yedunhu bhodhi inoratidzwa muMufananidzo 2 inonyanya kushandiswa mukuputika-uchapupu hwekuvhara uye nekudaro inozviisa pasi pemichina yakawanda mipimo.Kuvakazve ruzivo urwu mumudziyo weEDA kunogona kutora nguva yakareba uye kusashanda.Nekuti, mainjiniya emuchina vanogona kunge vakagadzira iyo yakavharirwa, yedunhu bhodhi chimiro, inokwirisa gomba nzvimbo, uye kureba zvirambidzo zvinodiwa nemugadziri wePCB.

Pamusana pearc uye radius mubhodhi redunhu, nguva yekuvakazve inogona kuva yakareba kudarika inotarisirwa kunyange kana chimiro chebhodhi redunhu chisina kuoma (sezvinoratidzwa mumufananidzo 3).

Iyi ingori mienzaniso mishoma yezvimiro zvebhodhi redunhu rakaoma.Nekudaro, kubva kune zvemazuva ano zvigadzirwa zvemagetsi zvevatengi, iwe uchashamisika kuona kuti akawanda mapurojekiti anoedza kuwedzera ese mabasa mupakeji diki, uye iyi package haisi nguva dzose rectangular.Iwe unofanirwa kufunga nezve smartphones uye mahwendefa kutanga, asi kune yakawanda yakafanana mienzaniso.

Kana ukadzorera motokari yairenda, unogona kuona weta achiverenga mashoko emotokari nekashina kanobata ruoko, wozokurukura nehofisi pasina waya.Mudziyo wacho wakabatanawo neprinta yekudziya yekutsikisa risiti yekukurumidza.Muchokwadi, zvese izvi zvishandiso zvinoshandisa zvakaomesesa / zvinochinjika zvedunhu mabhodhi (Figure 4), uko echinyakare PCB redunhu mabhodhi anobatanidzwa neanochinjika akadhindwa maseketi kuitira kuti anogona kupetwa munzvimbo diki.

Zvadaro, mubvunzo ndewokuti "nzira yekuendesa iyo yakatsanangurwa meinjiniya maratidziro muPCB maturusi ekugadzira?"Kushandisazve aya data mumakina ekudhirowa kunogona kubvisa kudzokorora kwebasa, uye zvakanyanya kukosha, kubvisa zvikanganiso zvevanhu.

Tinogona kushandisa DXF, IDF kana ProSTEP fomati kuunza ruzivo rwese muPCB Layout software kugadzirisa dambudziko iri.Kuita izvi kunogona kuchengetedza nguva yakawanda uye kubvisa kukanganisa kunobvira kwevanhu.Zvadaro, tichadzidza nezvemafomati aya rimwe nerimwe.

DXF ndiyo yekare uye inonyanya kushandiswa fomati, iyo inonyanya kuchinjanisa data pakati pemakanika uye PCB madhizaini edhizaini.AutoCAD yakaigadzira mukutanga kwema1980.Iyi fomati inonyanya kushandiswa kune maviri-dimensional data exchange.Vazhinji vatengesi vePCB zvishandiso vanotsigira iyi fomati, uye inorerutsa kuchinjanisa data.DXF kuunza / kutumira kunze kwenyika kunoda mamwe mabasa ekudzora maseru, akasiyana masangano uye mayuniti ayo achashandiswa mukutsinhana maitiro.Mufananidzo 5 muenzaniso wekushandisa Mentor Graphics 'PADS chishandiso kupinza iyo yakaoma kwazvo yedunhu bhodhi chimiro muDXF fomati:

Makore mashoma apfuura, 3D mabasa akatanga kuoneka muPCB maturusi, saka fomati inogona kutamisa 3D data pakati pemichina nePCB maturusi anodiwa.Nekuda kweizvozvo, Mentor Graphics yakagadzira iyo IDF fomati, iyo yakazoshandiswa zvakanyanya kuendesa redunhu bhodhi uye ruzivo rwechikamu pakati pePCB uye maturusi emuchina.

Kunyangwe iyo DXF fomati inosanganisira saizi yebhodhi uye ukobvu, iyo IDF fomati inoshandisa X uye Y chinzvimbo chechikamu, nhamba yechikamu, uye Z-axis kureba kwechikamu.Iyi fomati inovandudza zvakanyanya kugona kuona PCB mune matatu-dimensional maonero.Iyo IDF faira inogona zvakare kusanganisira rumwe ruzivo nezve nzvimbo inorambidzwa, senge kureba kurambidzwa kumusoro uye kuzasi kwebhodhi redunhu.

Iyo sisitimu inoda kukwanisa kudzora zvinyorwa zviri muIDF faira nenzira yakafanana kune DXF parameter yekumisikidza, sezvakaratidzwa muMufananidzo 6. Kana zvimwe zvikamu zvisina ruzivo rwehurefu, IDF kunze kwenyika inogona kuwedzera ruzivo rusipo panguva yekusika. process.

Imwe mukana weiyo IDF interface ndeyekuti chero bato rinogona kufambisa zvikamu kunzvimbo itsva kana kushandura chimiro chebhodhi, uyezve kugadzira imwe IDF faira.Izvo zvakashata zveiyi nzira ndeyokuti iyo yose faira inomiririra bhodhi uye chikamu chinoshanduka chinoda kudzoserwa kunze kwenyika, uye mune dzimwe nguva, inogona kutora nguva yakareba nekuda kwehukuru hwefaira.Mukuwedzera, zvakaoma kuziva kuti ndedzipi shanduko dzakaitwa nefaira itsva yeIDF, kunyanya pamapuranga makuru edunhu.Vashandisi veIDF vanogona kupedzisira vagadzira zvinyorwa zvetsika kuti vaone shanduko idzi.

Kuitira kufambisa zvirinani data re3D, vagadziri vari kutsvaga nzira yakavandudzwa, uye STEP fomati yakatanga.Iyo STEP fomati inokwanisa kuendesa saizi yebhodhi uye chimiro chechikamu, asi zvinonyanya kukosha, chikamu hachisisiri chimiro chakareruka chine hurefu hunokosha chete.Iyo STEP chikamu modhi inopa yakadzama uye yakaoma inomiririra yezvikamu mune matatu-dimensional fomu.Ose ari maviri edunhu bhodhi uye ruzivo rwechikamu anogona kutamiswa pakati pePCB nemichina.Nekudaro, hapasati paine nzira yekutevera shanduko.

Kuti tivandudze kuchinjana kwe STEP mafaira, takaunza iyo ProSTEP fomati.Iyi fomati inogona kufambisa data yakafanana neIDF ne STEP, uye ine kuvandudzwa kukuru-inokwanisa kuronda shanduko, uye inogona kupawo kugona kushanda muhurongwa hwekutanga hwechidzidzo uye kuongorora chero shanduko mushure mekutanga hwaro.Pamusoro pekuona shanduko, PCB uye mainjiniya emuchina anogonawo kubvumidza zvese kana zvega zvega shanduko mukurongeka uye bhodhi chimiro.Vanogonawo kupa hukuru hwakasiyana hwebhodhi kana nzvimbo dzechikamu.Kukurukurirana uku kwakagadziridzwa kunogadza ECO (Engineering Change Order) isati yambovapo pakati peECAD neboka remagetsi (Mufananidzo 7).

Nhasi, mazhinji ECAD uye mechanical CAD masisitimu anotsigira kushandiswa kweProSTEP fomati yekuvandudza kutaurirana, nekudaro kuchengetedza nguva yakawanda uye kuderedza zvinodhura zvikanganiso zvinogona kukonzerwa neakaoma electromechanical magadzirirwo.Zvinotonyanya kukosha, mainjiniya anogona kugadzira yakaomesesa yedunhu bhodhi chimiro nezvimwe zvirambidzo, uye vobva vaendesa ruzivo urwu nemagetsi kudzivirira mumwe munhu kutsanangura zvisirizvo saizi yebhodhi, nekudaro kuchengetedza nguva.

Kana usati washandisa aya DXF, IDF, STEP kana ProSTEP mafomati edata kuchinjana ruzivo, unofanirwa kutarisa mashandisiro awo.Funga kushandisa iyi yemagetsi data kuchinjanisa kurega kutambisa nguva kuumbazve yakaoma redunhu bhodhi zvimiro.
