[VW PCBworld] PCB yathunthu yomwe timalingalira nthawi zambiri imakhala yokhazikika pamakona anayi.Ngakhale kuti mapangidwe ambiri alidi amakona anayi, mapangidwe ambiri amafunikira matabwa ozungulira osakanikirana, ndipo mawonekedwe oterowo nthawi zambiri amakhala ovuta kupanga.Nkhaniyi ikufotokoza momwe mungapangire ma PCB osakhazikika.

Masiku ano, kukula kwa PCB kukucheperachepera, ndipo ntchito mu board board zikuchulukiranso.Kuphatikizidwa ndi kuchuluka kwa liwiro la wotchi, kapangidwe kake kamakhala kovuta kwambiri.Kotero, tiyeni tiwone momwe tingachitire ndi matabwa ozungulira omwe ali ndi mawonekedwe ovuta kwambiri.

Zolemba zosavuta za PCI board zitha kupangidwa mosavuta mu zida zambiri za EDA Layout.Komabe, pamene mawonekedwe bolodi dera ayenera kusinthidwa kwa nyumba zovuta ndi zoletsa kutalika, si kophweka kwa okonza PCB, chifukwa ntchito mu zida izi si ofanana ndi kachitidwe makina CAD.Mabwalo ozungulira ovuta amagwiritsidwa ntchito makamaka m'malo osaphulika, motero amakhala ndi zoletsa zambiri zamakina.

Kumanganso izi mu zida za EDA kungatenge nthawi yayitali ndipo sizothandiza kwambiri.Chifukwa, injiniya wamakina akuyenera kuti adapanga malo otchingidwa, mawonekedwe a board board, malo otsekera dzenje, ndi zoletsa zautali zomwe zimafunidwa ndi wopanga PCB.

Chifukwa cha arc ndi radius mu bolodi la dera, nthawi yomanganso ikhoza kukhala yayitali kuposa momwe amayembekezera ngakhale mawonekedwe a board board sakhala ovuta.
　　
Komabe, kuchokera kuzinthu zamakono zamagetsi zamagetsi, mudzadabwa kupeza kuti mapulojekiti ambiri amayesa kuwonjezera ntchito zonse mu phukusi laling'ono, ndipo phukusili silikhala lakona.Muyenera kuganizira za mafoni ndi mapiritsi poyamba, koma pali zitsanzo zambiri zofanana.

Mukabweza galimoto yobwereka, mutha kuwona woperekera zakudyayo akuwerenga zomwe zalembedwa pagalimotoyo ndi sikani ya m'manja, ndiyeno kuyankhulana ndi ofesi popanda zingwe.Chipangizocho chimalumikizidwanso ndi chosindikizira chotenthetsera kuti chisindikizidwe pompopompo.M'malo mwake, zida zonsezi zimagwiritsa ntchito matabwa okhazikika / osinthika, pomwe matabwa amtundu wa PCB amalumikizidwa ndi mabwalo osinthika osindikizidwa kuti apangidwe kukhala malo ang'onoang'ono.
　　
Kodi mungalowetse bwanji zomwe zafotokozedwa muukadaulo wamakina mu chida cha PCB?

Kugwiritsiranso ntchito deta iyi muzojambula zamakina kumatha kuthetsa kubwerezabwereza kwa ntchito, ndipo chofunika kwambiri, kuthetsa zolakwika zaumunthu.
　　
Titha kugwiritsa ntchito mtundu wa DXF, IDF kapena ProSTEP kulowetsa zonse mu pulogalamu ya PCB Layout kuti tithetse vutoli.Izi zitha kupulumutsa nthawi yambiri ndikuchotsa zolakwika zomwe anthu angakumane nazo.Kenako, tiphunzira za mitundu iyi imodzi ndi imodzi.

DXF

DXF ndiye mtundu wakale kwambiri komanso wogwiritsidwa ntchito kwambiri, womwe umasinthasintha kwambiri pakati pa madera opangira makina ndi PCB pakompyuta.AutoCAD idapanga izi koyambirira kwa 1980s.Mtunduwu umagwiritsidwa ntchito kwambiri posinthana ndi mitundu iwiri ya data.

Othandizira ambiri a PCB amathandizira mtundu uwu, ndipo imathandizira kusinthana kwa data.Kulowetsa / kutumiza kunja kwa DXF kumafuna ntchito zowonjezera kuti ziwongolere zigawo, mabungwe osiyanasiyana ndi mayunitsi omwe adzagwiritsidwe ntchito posinthanitsa.
