Enqubweni ye-PCB Design, ukuhlukaniswa kwendiza yamandla noma ukwahlukaniswa kwendiza yomhlabathi kuzoholela endizeni engaphelele. Ngale ndlela, lapho isinali liqhutshwa, indiza yalo izoba selisuka endizeni eyodwa yamandla iye kwenye indiza yamandla. Le nto ibizwa ngokuthi yiSiginali Span Division.

Umdwebo we-Schematic we-Cross-Segmentation Penomena
 
Ukuhlukaniswa kwesiphambano, ngoba isiginali yejubane eliphansi kungenzeka ukuthi awunabo ubudlelwano, kepha ohlelweni lwesiginali yedijithali ephezulu, isikhangiso esiphezulu sithatha ireferensi yendiza njengendlela yokubuya, okungukuthi, indlela yokubuya. Lapho indiza yesethenjwa ingaphelele, imiphumela elandelayo emibi izokwenzeka: ukuhlukaniswa kwesiphambano kungenzeka kungabi lula ngezimpawu zesikhashana esiphansi, kepha amasibili aphezulu wesiginali wedijithali, amasiginali wejubane eliphezulu athatha indiza njengendlela yokubuya, okungukuthi, indlela yokubuya. Lapho indiza yesethenjwa ingaphelele, le miphumela emibi elandelayo izokwenzeka:
l ukunqanyulwa kwe-distedance okuholela ekusebenzeni kocingo;
l Kulula ukudala crosstalk phakathi kwamasiginali;
l Kubangela ukubonakaliswa phakathi kwezimpawu;
l I-wavexform ye-wavexfork kulula ukuzulazula ngokwandisa indawo ye-loop yamanje kanye nokuqanjwa kwe-loop.
l Ukuphazanyiswa kwemisebe esikhaleni kuyanda futhi amandla kazibuthe asendaweni athinteka kalula.
l Khuphula amathuba okuhlangana kazibuthe neminye imibuthano ebhodini;
l I-voltage frequency voltage yehla ku-loop inductor yakha umthombo wemisebe yemisebe ejwayelekile, ekhiqizwa ngentambo yangaphandle.
 
Ngakho-ke, i-PCB Wiring kufanele ibe seduze nendiza ngangokunokwenzeka, futhi igweme ukwahlukanisa. Uma kudingeka ukuwela ukwahlukanisa noma ngeke kube eduze kwendiza yomhlaba wamandla, lezi zimo zivunyelwe kuphela kulayini wesiginali wejubane eliphansi.
 
Ukucubungula ukwahlukanisa ekwakhiweni
Uma ukwahlukanisa akunakugwenywa ku-PCB Design, Ungabhekana kanjani nayo? Kulokhu, ukuhlukaniswa kudinga ukulungiswa ukuze kunikeze indlela yokubuyisa emfushane yesiginali. Izindlela ezijwayelekile zokucubungula zifaka ukwengeza i-capacitor yokulungisa nokuwela ibhuloho le-wire.
l Ama-capacitor ama-stiching
I-0402 noma i-0603 Ceramic Capacitor enomthamo we-0.01uf noma i-0.1UF ivame ukubekwa esigabeni sesiphambano sesiginali. Uma izimvume zesikhala, amanye ama-capacitors anjalo angangezwa.
Ngasikhathi sinye, zama ukuqinisekisa ukuthi ucingo lwesiginali lungaphakathi kobubanzi bokuthunga kwe-200mil ukuthunga, futhi okuncane ibanga, okungcono; Amanethiwekhi emikhawulweni yomibili ye-capacitor ngokulandelana ahambelana namanethiwekhi endiza yereferensi lapho kudlula khona amasiginali. Bona amanethiwekhi axhumeke kuwo womabili amaphethelo we-capacitor kwisibalo esingezansi. Amanethiwekhi amabili ahlukene aqokonyiswe ngemibala emibili yile:

lBridge ngaphezulu kocingo
Kujwayelekile "inqubo yomhlaba" isiginali kulo lonke leli yunithi engxenyeni yesiginali, futhi ingahle ibe yinye imigqa yesiginali yenethiwekhi, umugqa we- "Ground" ukhulu ngangokunokwenzeka

Amakhono we-wiring wesiginali ephezulu
a)ukuxhumeka kwe-multilayer
Isifunda esiphezulu se-Speed ​​Signal Signal Rounting sivame ukuhlanganiswa okuphezulu, ukuhlanganiswa okuphezulu kwe-wiring, ukusebenzisa ibhodi le-multilayer akudingekile kuphela kwi-wiring, kodwa futhi nezindlela ezisebenzayo zokunciphisa ukuphazamiseka.
 
Ukukhetha okunengqondo kwezingqimba kunganciphisa kakhulu usayizi webhodi lokuphrinta, kungenza ukusetshenziswa okugcwele kwesendlalelo esiphakathi ukusetha isihlangu, kunganciphisa kangcono ukufakwa kwesiginali, kunganciphisa ngempumelelo amandla okudlulisela phakathi kwamasiginali, njll.
b)Ukuhola okungapheli, okungcono
Ukuhola okuncane okugoqiwe phakathi kwezikhonkwane zamadivayisi wesifunda esiphakeme, okungcono.
Ukuhola kwe-wiring kwesifunda esisheshayo se-Signal Rounting Rounting Resign amukele umugqa oqondile oqondile futhi kudinga ukujika, okungasetshenziswa njenge-45 ° polyline noma i-arc. Lesi sidingo sisetshenziselwa ukuthuthukisa amandla okubamba we-foil yensimbi esifundazweni esiphansi.
Emibuthanweni yejubane eliphezulu, ukubhekana nale mfuneko kunganciphisa ukudluliselwa kanye nokuhlanganiswa kwezimpawu zesivinini esikhulu, futhi kunciphise imisebe nokuboniswa kwezimpawu.
c)Okufushane ukuhola, okungcono
Okufushane ukuholwa phakathi kwezikhonkwane zesisu sejubane eliphakeme kakhulu le-Signal Routing Routing, okungcono.
Uma kuhamba isikhathi eside, kukhudlwana inani lokusakazwa nokusakazwa kwenani, okuzoba nethonya eliningi ekuphasisweni kwesiginali ephezulu yesistimu, kodwa futhi lishintsha isimo sokuvikelwa kwesifunda, okuphumela ekubonisweni nase-Oscillation yohlelo.
d)Ukushintshana okuncane phakathi kwezendlalelo zokuhola, okungcono
Ukuguqulwa kwe-interlayer okuncane phakathi kwezikhonkwane zamadivayisi wesifunda esiphakeme, okungcono.
Okubizwa ngokuthi "ukuguquguquka kwe-interlayer encane kwe-lead, okungcono" kusho ukuthi izimbobo ezimbalwa ezisetshenziswe ekuxhumaneni kwezakhi, okungcono. Kukalwe ukuthi umgodi owodwa ungaletha cishe i-0.5pf yokusakazwa kwamakhono, okuholela ekwandeni okukhulu kokubambezeleka kwesifunda, ukunciphisa inani lezimbobo zingathuthukisa kakhulu ijubane
e)Qaphela Ukuphazanyiswa Kwesiphamba
I-Wiring yesiginali ephezulu kufanele inake "ukuphazamiseka kwesiphambano" kwethulwa yi-Signal Line Dabung Detal Light Parallel Wiring. Uma ukusatshalaliswa okuhambisanayo kungagwenywa, indawo enkulu "yendawo" ingahlelwa ngakolunye uhlangothi lomugqa wesiginali ofanayo ukuze unciphise kakhulu ukuphazanyiswa.
f)Gwema amagatsha neziqu
I-wiring yesiginali ephezulu kufanele igweme ukugabha noma ukwakha i-stub.
Ama-Stumps anomphumela omuhle ekulweni futhi angadala ukuboniswa kwesiginali futhi amboze ngokweqile, ngakho-ke kufanele sivikele iziqu namagatsha ekwakhiweni.
I-Wiisy Chain Wiring izonciphisa umthelela esisayinweni.
g)Imigqa yesiginali iya ngaphakathi phansi ngangokunokwenzeka
I-High Frequency Signal Line Line Phezu kobuso kulula ukukhiqiza imisebe emikhulu kagesi, futhi kulula futhi ukuphazanyiswa ngemisebe ye-electromagnetic yangaphandle noma izinto.
Umugqa wesiginali wemvamisa ophakeme uqhutshwa phakathi kokunikezwa kwamandla kanye nocingo lomhlabathi, ngokufakwa kwegagasi le-electromagnetic ngokuhlinzekwa kwamandla kanye nongqimba olungaphansi, kukhiqizwa imisebe ekhiqizwayo kuyoncishiswa kakhulu.
