1. Kugadzirira
Kusanganisira kugadzirira kwechikamu maraibhurari uye schematics.Pamberi pePCB dhizaini, tanga wagadzirira schematic SCH chikamu raibhurari uye PCB chikamu pasuru raibhurari.
PCB chikamu pasuru raibhurari inosimbiswa zvakanyanya nemainjiniya zvichienderana neyakajairwa saizi ruzivo rwechishandiso chakasarudzwa.Mukutanga, tanga wamisa iyo PC chikamu pasuru raibhurari, uye wobva wamisa schematic SCH chikamu raibhurari.
PCB chikamu pasuru raibhurari inonyanya kudiwa, inobata zvakananga PCB yekumisikidza;schematic SCH chikamu raibhurari zvinodiwa zvakadekara, asi teerera kune tsananguro yezvakanaka pini zvivakwa uye tsamba nePCB chikamu pasuru raibhurari.
2. PCB chimiro chekugadzira
Zvinoenderana nesaizi yebhodhi yakatemerwa uye akasiyana mekiniki chinzvimbo, iyo PCB dhizaini dhizaini yekudhirowa PCB bhodhi furemu, uye yekumisikidza zvinodiwa kuti uise zvinosungirirwa, makiyi / switch, screw maburi, maburi egungano, nezvimwe.
Nyatsofunga uye sarudza nzvimbo yewaya uye isiri-waya nzvimbo (senge yakawanda sei yakatenderedza gomba rekukona ndeyenzvimbo isiri-waya).
3. PCB dhizaini yekugadzira
Layout dhizaini ndiko kuiswa kwemidziyo muPCB furemu zvinoenderana nezvinodiwa zvekugadzira.Gadzira tafura yetiweki mune schematic chishandiso (Gadzira → GadziraNetlist), uye wobva wapinza iyo network tafura muPCB software (Design→ImportNetlist).Mushure mekubudirira kupinza tafura yetiweki ichavepo kumashure kwesoftware, kuburikidza neKuisa mashandiro anogona kuve ese maturusi akadanwa, pakati pepini nemazano anobhururuka akabatana, ipapo unogona kugadzira marongerwo echigadzirwa.
PCB dhizaini dhizaini ndiyo yekutanga yakakosha maitiro mune yese dhizaini dhizaini yePCB, iyo yakanyanya kuoma PCB bhodhi, zvirinani marongerwo anogona kukanganisa zvakananga kusununguka kwekuita kweiyo gare gare wiring.
Dhizaini yedhizaini inotsamira pane yedunhu bhodhi mugadziri hunyanzvi hwedunhu uye ruzivo rwedhizaini, dhizaini dhizaini idanho repamusoro rezvinodiwa.Junior wedunhu bhodhi vagadziri vachiri vasina kudzika ruzivo, vanokodzera diki module dhizaini kana iyo bhodhi yese haina kuoma PCB dhizaini dhizaini mabasa.
4. PCB wiring design
PCB wiring dhizaini ndiyo yakakura basa rekuita muPCB dhizaini yese, iyo inokanganisa zvakananga kuita kwePCB board.
Mukugadzira maitiro ePCB, wiring kazhinji ine nzvimbo nhatu.
Chekutanga, jira kuburikidza, inova ndiyo inonyanya kukosha yekupinda inodiwa yePCB dhizaini.
Chechipiri, kushanda kwemagetsi kusangana, inova chiyero chekuti PCB bhodhi inokodzera zviyero, mushure memutsara kuburikidza, kunyatsogadzirisa wiring, kuitira kuti iwane zvakanakisisa kushanda kwemagetsi.
Kamwe zvakare yakatsvinda uye yakanaka, isina kurongeka wiring, kunyange kana magetsi kuita kuchaitawo kuunza kusagadzikana kukuru kune gare gare optimization yebhodhi uye kuyedza nekugadzirisa, wiring zvinodiwa zvakatsvinda uye zvakarongeka, hazvigone crisscrossed pasina mitemo nemirau.
5. Wiring optimization uye silkscreen kuiswa
"PCB dhizaini haisi iyo yakanyanya kunaka, irinani chete", "PCB dhizaini inyanzvi ine hurema", kunyanya nekuti PCB dhizaini yekuzadzisa zvinodiwa zvekugadzira zvakasiyana-siyana zvehardware, uye zvinodiwa nemunhu zvinogona kunge zvichipokana pakati pehove nebere. paw haigone kuva ese ari maviri.
Semuenzaniso: PCB dhizaini purojekiti mushure memugadziri webhodhi kuti aongorore kudiwa kwekugadzira 6-layer bhodhi, asi chigadzirwa Hardware yekufunga mutengo, izvo zvinodiwa zvinofanirwa kugadzirwa se4-layer board, ipapo chete nekudhura kwe chiratidzo shield yepasi layer, zvichikonzera kuwedzera kwechiratidzo crosstalk pakati pepedyo wiring layer, iyo chiratidzo chemhando ichaderedzwa.
Iyo yakajairika dhizaini chiitiko ndeye: optimize iyo wiring nguva inopetwa kaviri nguva yekutanga wiring.PCB wiring optimization inopedzwa, kudiwa kwemashure-kugadzirisa, iyo yekutanga kugadzirisa ndeye PCB bhodhi pamusoro peiyo sirika-screen logo, dhizaini yepasi pasi peiyo silk-screen mavara inoda kuita girazi kugadzirisa, kuti usaite. kuvhiringidza nechepamusoro pesiriki-skrini.
6. Network DRC cheki uye chimiro chekutarisa
Kudzora kwehunhu chikamu chakakosha chePCB dhizaini dhizaini, iyo yakajairika nzira dzekudzora mhando dzinosanganisira: dhizaini yekuzviongorora, dhizaini yekuongorora, misangano yekuongorora nyanzvi, kuongorora kwakakosha, nezvimwe.
Schematic uye zvimiro zvedhayagiramu ndizvo zvinonyanya kukosha dhizaini zvinodiwa, network yeDRC cheki uye chimiro chekutarisa ndeyekusimbisa kuti PCB dhizaini yekusangana nehurongwa hwemambure uye zvimiro zvedhiyagiramu yemamiriro maviri ekupinza.
General board designers vachange vaine yavo yakaunganidzwa yemhando yecheki Cheki Cheki, inova chikamu chezvinyorwa kubva kukambani kana dhipatimendi zvakatemwa, chimwe chikamu kubva kune yavo ruzivo muchidimbu.Cheki dzakakosha dzinosanganisira dhizaini yeValor cheki uye cheki yeDFM, zvikamu zviviri izvi zvemukati zvine chekuita nePCB dhizaini inobuda kumashure-yekupedzisira kugadzirisa mwenje yekudhirowa faira.
7. PCB bhodhi kugadzira
MuPCB zviri pamutemo kugadziriswa pamberi pebhodhi, mugadziri webhodhi redunhu anofanirwa kutaurirana nePCB A bhodhi fekitori fekitori PE, kuti apindure mugadziri paPCB bhodhi kugadzirisa nyaya dzekusimbisa.
Izvi zvinosanganisira, asi hazvigumiri kune: kusarudzwa kwePCB bhodhi mhando, mutsara wakafara mutsara mutsara wepakati kugadziriswa kweiyo mutsara layer, impedance control kugadziridzwa, PCB lamination ukobvu kugadziridzwa, pamusoro pekurapa kugadzirisa maitiro, gomba kushivirira kutonga uye kuendesa zviyero.
