Imbaraga zamashanyarazi
Amazungu ya Digital akunze gusaba imigezi ihagarara, bityo imigezi ikorwa kubikoresho byihuta cyane.
Niba ingufu zamashanyarazi ari ndende cyane, kuboneka kwa interineti bizatera urusaku rwinshi, kandi iyi rusaku rwinshi ruzatangizwa mubindi bimenyetso. Mu muvuduko mwinshi, hazashobora kuba inductance ya parasitike, irwanya parasitike, uburyo bwo kurwanya parasitike ndetse no guhabwa umutima muremure kandi bizaganisha ku bushobozi bwo kugabanuka kwiyongera, kandi kuboneka kwa parasitika kandi biganisha ku kugabanuka kw'igice kinini, kandi ko hazabaho igabanuka rya voltage igice, rishobora guhagarika umuzunguruko.
Kubwibyo, ni ngombwa cyane cyane kongera akazi ka bypass imbere yigikoresho cya digitale. Ubwishobozi bunini, ingufu zo kohereza zigarukira kubipimo byoherejwe, bityo ubushobozi bunini kandi ubushobozi buto bwahujwe no guhura nurwego rwuzuye.
Irinde ibibanza bishyushye: Ikimenyetso cya Dias kizabyara imva ku butaka no hasi. Kubwibyo, gushyiramo uruhare bidafite ishingiro cya vias birashoboka ko byongera ubucucike buriho mubice bimwe byimbaraga cyangwa indege. Utwo turere aho ubunebwe bwaho bwiyongera bwitwa ahantu hashyushye.
Tugomba rero kugerageza uko dushoboye kugirango twirinde iki kibazo mugihe ushizeho vias, kugirango wirinde indege gutandukana, amaherezo bizaganisha ku bibazo bya EMC.
Mubisanzwe inzira nziza yo kwirinda ibibanza bishyushye ni ugushyira vias muburyo bwa mesh, kuburyo ubwinshi bwaho butarimwe, kandi indege ntizirimburwa icyarimwe, kandi indege ntiziba ndende cyane, kandi ibibazo bya EMC ntibizabaho.

Uburyo bwo kunyerera bwa trace
Iyo ushizeho imirongo yihuta yihuta, irinde kunama imirongo yikimenyetso bishoboka. Niba ugomba kunama
Iyo ushinsa imirongo yihuta, dukoresha imirongo yinzoka kugirango tugere kuburebure bungana. Umurongo umwe w'inzoka mubyukuri ni ubwoko bwunamye. Umurongo wa kabiri, intera, hamwe nuburyo bwo kunyeganyega rwose bigomba gutorwa muburyo bushyize mu gaciro, kandi spacing igomba guhura na 4w / 1.5w.

Ikimenyetso
Niba intera iri hagati yimirongo yihuta yihuta cyane cyane, biroroshye gutanga ibihingwa. Rimwe na rimwe, kubera imiterere, ingano yinama nizindi mpamvu, intera iri hagati yimirongo yihuta yihuta irenze intera ndende, noneho dushobora kongera intera iri hagati yimirongo yihuta cyane hafi yicungu. intera.
Mubyukuri, niba umwanya uhagije, gerageza kongera intera iri hagati yimirongo ibiri yihuta.

Impetance ntabwo ikomeza
Agaciro kangarugero kakamwe mubisanzwe biterwa numurongo wacyo nintera iri hagati ya trase hamwe nindege yerekanwe. Umukomeretsa ibimenyetso, hepfo impeta. Muburyo bumwe na sontial hamwe nibikoresho, ihame rirakoreshwa.
Iyo padi ya interineti ihuza umurongo wihuta cyane, niba padi ari muto cyane, kandi umurongo wihuta cyane cyane, intera ya padi nini ni nto, kandi ibimenyetso bifunganye bigomba kugira nabi. Muri uru rubanza, kutabuza kwabuza bizabaho, kandi kwerekana ibimenyetso bizabaho niba impetomu idahagarara.
Kubwibyo, kugirango ukemure iki kibazo, urupapuro rwubujijwe rushyirwa munsi yimpapuro nini cyangwa igikoresho kinini, hamwe nindege ya padi yashyizwe kurundi rwego kugirango yongere imbaraga zo kongera induru zikomeza.
Vias ni irindi soko ryimpongo zidakuraho. Kugirango ugabanye iyi ngaruka, uruhu rwumuringa rudakenewe guhuzwa nikintu cyimbere hamwe na Bikwiye Byakuweho.
Mubyukuri, ubu busa bushobora kuvaho ibikoresho bya Cad mugihe cyo gushushanya cyangwa hamagara uruganda rutunganya PCB kugirango ukureho umuringa udakenewe kandi ukomeze gukomeza kwishyira hamwe.

Birabujijwe gutegura vias cyangwa ibice muburyo butandukanye. Niba vias cyangwa ibice bishyirwa mubice bitandukanye, ibibazo bya EMC bizabaho kandi bitagereranywa nabyo bizazavamo.
Rimwe na rimwe, imirongo imwe yihuta yihuta igomba guhuzwa murukurikirane hamwe nubushobozi bwo guhuza. Guhahuha nacyo bigomba gutondekwa, kandi paki ya capator ya kodegisi idakwiye kuba nini cyane. Birasabwa gukoresha 0402, 0603 nabyo byemewe, kandi ubushobozi bwo hejuru ya 0805 cyangwa imbaraga-kuruhande nibyiza kutakoreshwa.
Mubisanzwe, Vas azatanga ibintu byinshi bidasubirwaho, bityo rero kumurongo wihuta cyane, gerageza kugabanya vias, kandi niba ushaka gukoresha vias, ubatere.

Uburebure bungana
Mubisobanuro byihuse-byihuta, muri rusange, nka bisi, igihe cyo kuhagera nigihe cyo gutangira ikosa hagati yimirongo yikimenyetso kugiti cye igomba gusuzumwa. Kurugero, mumatsinda ya bisi yihuta yo hejuru, igihe cyo kuhagera cyikimenyetso cyamakuru kigomba kwizerwa mugihe cyigihe gito cyo guhagarika igihe cyo guhagarika igihe cyagenwe nigihe cyo gukora. Kugirango duhuze iki cyifuzo, tugomba gusuzuma uburebure bungana.
Umurongo wihuta utandukanya ikimenyetso cyigihe gito cyane kubijyanye n'imirongo ibiri y'ibimenyetso, bitabaye ibyo itumanaho rishobora gutsindwa. Kubwibyo, kugirango duhuze iki gisabwa, umurongo w'inzoka urashobora gukoreshwa kugirango ugere ku burebure bungana, bityo ushyireho igihe gisabwa.
Umurongo w'inzoka ugomba gushyirwa ahagaragara isoko yo gutakaza uburebure, ntabwo ari iherezo rya kure. Gusa ku nkomoko irashobora kwerekana ibimenyetso byiza kandi bibi byumurongo utandukanye woherejwe mugihe kinini.

Niba hari ibimenyetso bibiri byunamye kandi intera iri hagati yabyo iri munsi ya 15mm, gutakaza uburebure hagati yabyo bigomba kwishyura muri iki gihe, bityo nta mpamvu yo gutunganya uburebure bungana muri iki gihe.
Kubice bitandukanye byimirongo yihuta yihuta, bagomba kuba bafite uburebure bungana bwigenga. Vias, urukurikirane rwa capling, hamwe na terefone yihuta ni imirongo yihuta yihuta igabanijwemo ibice bibiri, bityo rero witondere cyane muri iki gihe.
Igomba kuba ndende ukundi. Kuberako software nyinshi za Eda zititaye gusa niba ufite ibinyuhiriza byose byatakaye muri DRC.
Kugirango imikoreshereze nka LVD yerekana ibikoresho, hazabaho ibice bibiri bitandukanye icyarimwe, kandi ibisabwa nigihe hagati yabyo muri rusange birakabije, kandi igihe cyo gutinda ni gito cyane. Kubwibyo, kubimenyetso nkibi bitandukanye, muri rusange turabasaba kuba mu ndege imwe. Gutanga indishyi. Kuberako umuvuduko wo kohereza ibimenyetso wibice bitandukanye biratandukanye.
Iyo software zimwe na zimwe za Eda zibara uburebure bwinzira, ibimenyetso biri imbere muri padi nabyo bizabarwa muburebure. Niba uburebure bwakozwe muriki gihe, ibisubizo nyabyo bizatakaza uburebure. Witondere rero muri iki gihe iyo ukoresheje software ya EDA.
Igihe icyo aricyo cyose, niba ubishoboye, ugomba guhitamo inzira imwe yo kwirinda kugirango wirinde gukenera gukora urugendo rwinzoka kuburebure bungana.
Niba imyanya yemerera, gerageza wongereho loop ntoya kumurongo mugufi kugirango ugere ku ndishyi, aho gukoresha umurongo w'inzoka kugirango wishyure.
