Sarudzo yePCB Bhodhi inofanirwa kurova chiyero pakati pemisangano yekugadzira zvinodiwa uye kugadzirwa kukuru uye mutengo. Dhizaini dzinodikanwa dzinosanganisira magetsi uye michina zvikamu. Dambudziko iri rinowanzo kuve rakakosha kana richirongedza yakanyanya-kumhanya PCB mabhodhi (frequency yakakura kupfuura GHZ).
Semuenzaniso, anowanzo shandiswa kwazvo Sekusvika pamagetsi zvine chekuita, teerera kune kuti difelectric nguva dzose uye dielectric kurasikirwa kwakakodzera kuwanda kwakagadzirwa.2. Nzira yekudzivirira yakakwira frequency kupindirana?
Pfungwa yekutanga yekudzivirira kukanganisika kwakanyanya-frequency ndeyekudzora kukanganiswa kweiyo Electromagnetic munda wemagetsi yakakwirira-frequents, iyo inonzi crosstalk (crosstalk) (crosstalk). Iwe unogona kuwedzera chinhambwe pakati pechiratidzo chepamusoro-chinomhanya uye iyo Analog chiratidzo, kana kuwedzera pasi Guard / sunt track inotevera kune Analog chiratidzo. Teerera zvakare kune ruzha kupindira kubva kuDhijitari pasi kune analog ivhu.3. Maitiro ekugadzirisa dambudziko rekutendeseka rakavimbika mukugadzirwa kwakanyanya-kumhanya?
Kuratidzira kwakanangana kunonetsa dambudziko rekutyisidzirwa. Izvi zvinhu zvinokanganisa zvimiro zvinosanganisira chimiro uye zvinobuda zvakarongedzwa zvechiratidzo siginecha, hunhu hwekutevera, hunhu hwekutakura. Mhinduro yacho ndeye kuvimba neiyo topology yekubviswa uye kugadziriswa kwe wiring.
4. Nzira yakasarudzika iri sei?
Kune maviri mapoinzi ekuteerera kune iyo mamiriro eiyo akasiyana maviri. Imwe ndeyekuti kureba kwemawaya maviri kunofanirwa kunge kwenguva yakareba sezvinobvira, uye imwe ndeyekuti chinhambwe chiri pakati pewaya mbiri (ichi chinhambwe chinotemerwa nekusiyanisa) chinofanira kuchengetwa nguva dzose, ndiko kuti, kuramba zvichienderana. Pane nzira mbiri dzakafanana, imwe ndeyekuti mitsara miviri iyi inomhanya kune imwe nyika-padivi, uye imwe ndeyekuti mitsara miviri iyi inomhanya pane maviri maviri ekutenderera (pamusoro-pasi pe). Kazhinji, iyo yekutanga chikamu-padivi (padivi-padivi, padivi-padivi) rinoitwa munzira dzakawanda.
5. Kuziva sei kusiyanisa wiring ye wiring ye wachi yewirimo ine imwe chete yekubuda terminal?
Kuti ushandise musiyano wiring wiring, zvine musoro kuti chiratidzo cheSosi uye anogamuchira masaga akasiyanisa masaini. Naizvozvo, hazvigoneke kushandisa kusiyanisa wiring ye wachi yewachi neye wega chete kubuda terminal.
6. Inogona kupesana neanogona kuwedzerwa pakati peiyo mutsetse mutsetse vaviri vaviri pakugamuchira?
Iko kupokana kwekunetseka pakati pemuviri mutsetse wedzinza pane kugashira kunowanzo kuwedzerwa, uye kukosha kwayo kunofanirwa kuve kwakaenzana nekukosha kwekusanganisa kusiyanisa. Iyi nzira iyo chiratidzo chiratidzo chichava nani.
7. Nei kushandisa musiyano wechipiri uchifanira kuve pedyo uye kufanana?
Wiring yemusiyano maviri anogona kunge ari kure nemvumo uye yakafanana. Iyo inonzi yakakodzera kusvika kure nekuti chinhambwe chinokanganisa kukosha kwekusiyanisa kusiyanisa, iyo inguva yakakosha paramende yekugadzira maviri akasiyana maviri. Iko kudikanwa kwekufananidza zvakare kuchengeta kuenderana kwekusanganisa kwekusanganisa. Kana mitsetse miviri iyi yakangoerekana yasvika uye iri pedyo, kusiyanisa kusiyanisa hakuzowirirane, iko kuchakanganisa kutendeka kwesina chiratidzo uye kunonoka nguva.
