Iyo PCB yedunhu bhodhi inogona kusanganisa akawanda emagetsi zvikamu pamwe chete, izvo zvinogona kuchengetedza nzvimbo zvakanyanya uye hazvizokanganisa kushanda kwedunhu.Kune akawanda maitiro mukugadzirwa kwePCB redunhu bhodhi.Kutanga, isu tinofanirwa kuseta Tarisa maparameter ePCB redunhu bhodhi.Chechipiri, tinofanira kupinza zvikamu zvakasiyana-siyana munzvimbo dzazvo dzakafanira.

1. Pinda PCB dhizaini system uye isa ma parameter akakodzera

Seta zvimiro zvezvakatipoteredza zvehurongwa hwekugadzira zvinoenderana nemaitiro emunhu, senge saizi uye rudzi rwegridhi point, saizi uye rudzi rwechitubu, etc. Kazhinji kutaura, kukosha kweiyo system inogona kushandiswa.Mukuwedzera, zviyero zvakadai sehukuru uye nhamba yezvikamu zvebhodhi redunhu zvinofanira kuiswa.

2. Gadzira tafura yetiweki inotengeswa kunze kwenyika

Tafura yemambure ibhiriji uye chinongedzo pakati pedunhu schematic dhizaini uye yakadhindwa redunhu bhodhi dhizaini, iyo yakakosha.Iyo netlist inogona kugadzirwa kubva kudunhu schematic dhayagiramu, kana inogona kutorwa kubva kune iripo yakadhindwa redunhu bhodhi faira.Kana iyo tafura yetiweki yakaunzwa, zvinodikanwa kutarisa uye kugadzirisa zvikanganiso mudunhu schematic dhizaini.

3. Ronga nzvimbo yechikamu chimwe nechimwe

Iyo otomatiki dhizaini basa reiyo system inogona kushandiswa, asi otomatiki dhizaini basa harina kukwana, uye zvinodikanwa kugadzirisa nemaoko chinzvimbo chechikamu chimwe nechimwe.

4. Ita wering board wedunhu

Chimiro che otomatiki dhizaini bhodhi routing ndeye kuseta yakachengeteka chinhambwe, waya fomu uye zvimwe zvirimo.Parizvino, iyo otomatiki wiring basa remidziyo inenge yakakwana, uye iyo general circuit diagram inogona kufambiswa;asi marongerwo emamwe mitsara haagutsikane, uye wiring inogonawo kuitwa nemaoko.

5. Chengetedza neprinta yakabuda kana hard copy

Mushure mekupedza wiring yebhodhi redunhu, chengetedza iyo yapera dhiyagiramu dhizaini faira, uye ipapo shandisa akasiyana graphic ekubuda maturusi, akadai semaprinta kana plotters, kuburitsa wiring dhayagiramu yedunhu redunhu.

Electromagnetic kuenderana kunoreva kugona kwemidziyo yemagetsi kushanda zvakabatana uye zvinobudirira munzvimbo dzakasiyana dzemagetsi.Chinangwa ndechekugonesa michina yemagetsi kudzvanyirira kukanganisika kwakasiyana kwekunze, kugonesa michina yemagetsi kushanda zvakajairwa munzvimbo yakatarwa yemagetsi, uye panguva imwechete kuderedza kukanganiswa kwemagetsi emidziyo yemagetsi pachayo kune zvimwe zvemagetsi.Semupi wemagetsi ekubatanidza zvinhu zvemagetsi, chii chinowirirana dhizaini yePCB redunhu board?

1. Sarudza inonzwisisika waya upamhi.Sezvo kukanganisa kunokonzerwa nemhepo inopera pamitsetse yakadhindwa yePCB redunhu bhodhi inonyanya kukonzerwa nechikamu che inductance chetambo yakadhindwa, inductance yewaya yakadhindwa inofanira kuderedzwa.

2. Maererano nekuoma kwedunhu, kusarudzwa kwakanaka kwenhamba yePCB layer inogona kuderedza kukanganiswa kwemagetsi, kuderedza zvakanyanya PCB volume uye kureba kwechitsiko chezvino uye wiring yebazi, uye kuderedza zvakanyanya kupindirana pakati pezviratidzo.

3. Kutora nzira yakarurama yekugadzira uye kushandisa wiring yakaenzana inogona kuderedza inductance yewaya, asi iyo mutual inductance uye kugovera capacitance pakati pematare kuchawedzera.Kana iyo dhizaini ichibvumira, zviri nani kushandisa yakanyatsoumbwa mesh wiring chimiro.Iyo chaiyo nzira ndeyekuita rimwe divi rakadhindwa bhodhi rakachinjika Wiring, wiring kune rumwe rutivi vertically, uye ipapo kubatanidza nemakomba metallized pamuchinjikwa makomba.

4. Kuti udzivise crosstalk pakati petambo dzePCB redunhu bhodhi, edza kudzivisa kureba-kure yakaenzana wiring paunenge uchigadzira wiring, uye chengetedza chinhambwe pakati petambo sezvinobvira.cross.Kuisa mutsara wakadhindwa pakati pemamwe mitsara yechiratidzo inotarisisa kukanganisa kunogona kunyatso kudzvanya crosstalk.
