Zvisizvo PCB dhizaini

[VW PCBworld] Iyo yakazara PCB yatinofungidzira inowanzoita rectangular chimiro.Kunyangwe madhizaini mazhinji ari rectangular, magadzirirwo mazhinji anoda mabhodhi edunhu asina chimiro, uye maumbirwo akadaro kazhinji haasi nyore kugadzira.Ichi chinyorwa chinotsanangura maitiro ekugadzira maPCB asina kurongeka.

Mazuva ano, ukuru hwePCB huri kuderera, uye mabasa ari mubhodhi redunhu ari kuwedzerawo.Yakabatana nekuwedzera kwekumhanya kwewachi, dhizaini yave yakanyanya kuoma.Saka, ngatitarisei maitiro ekuita nemapuranga ematunhu ane mamwe maumbirwo akaoma.

 

Rakareruka PCI bhodhi maratidziro anogona kugadzirwa zviri nyore mune akawanda EDA Magadzirirwo maturusi.Nekudaro, kana iyo yedunhu bhodhi chimiro ichida kuchinjirwa kune yakaoma imba ine zvirambidzo zvehurefu, hazvisi nyore kune vanogadzira PCB, nekuti mabasa ari mumidziyo iyi haana kufanana neaya emakanika CAD masisitimu.Complex circuit boards anonyanya kushandiswa mukuputika-proof enclosures, saka ari pasi pezvirambidzo zvakawanda zvemuchina.

Kuvakazve ruzivo urwu mumidziyo yeEDA inogona kutora nguva yakareba uye haina kunyatsoshanda.Nekuti, mainjiniya emuchina anogona kunge akagadzira iyo yakavharirwa, yedunhu bhodhi chimiro, inokwirisa gomba nzvimbo, uye kureba zvirambidzo zvinodiwa nemugadziri wePCB.

Nekuda kwearc uye radius mubhodhi redunhu, nguva yekuvakazve inogona kunge yakareba kupfuura inotarisirwa kunyangwe chimiro chebhodhi chedunhu chisina kuoma.
  
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 ipapo.Muchokwadi, zvese izvi zvishandiso zvinoshandisa zvakaomesesa/zvinochinjika zvedunhu mabhodhi, uko echinyakare PCB redunhu mabhodhi anobatanidzwa neanochinjika akadhindwa maseketi kuitira kuti agopetwa munzvimbo diki.
  
Nzira yekupinza sei iyo yakatsanangurwa mechaniki engineering kutaurwa muPCB dhizaini chishandiso?

Kushandisazve aya data mumakina ekudhirowa kunogona kubvisa kudzokorora kwebasa, uye zvakanyanya kukosha, kubvisa kukanganisa kwevanhu.
  
Tinogona kushandisa DXF, IDF kana ProSTEP fomati kupinza ruzivo rwese muPCB Layout software kugadzirisa dambudziko iri.Izvi zvinogona kuchengetedza nguva yakawanda uye kubvisa kukanganisa kunogona kuitika kwevanhu.Zvadaro, tichadzidza nezvemafomati aya rimwe nerimwe.

DXF

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 PCB maturusi ezvishandiso 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.
