Mukuita kwePCB Dhizaini, chikamu cheiyo ndege ndege kana kupatsanurana kwendege yepasi kunotungamira kune isina kukwana ndege. Nenzira iyi, apo chiratidzo chakakundwa, ndege yenzvimbo yerefu ichapera kubva kune imwe nzvimbo yemagetsi kuenda kune imwe ndege. Ichi chiitiko chinonzi chiratidzo cheSignal Sign.
Schematic Diagram yeCross-Segmentation Phenomena
Chikamu chekuyambuka, cheiyo yakadzika mhanyisa chiratidzo inogona kunge isina hukama, asi mune yakakwira mhanyisa digital sign system, iyo yakakwirira yekumhanyisa chiratidzo inotora nzira yekudzokera senzira, ndiko kuti, nzira yekudzoka. Panzvimbo yereferensi isina kukwana, inotevera mhedzisiro ichaitika: Cross-segmentation inogona kunge isina kukodzera zviratidzo, Panzvimbo yereferente isingakwanisi, inotevera inokanganisa mhedzisiro ichatoitika:
l kusakwana kwekuregererwa kunokonzeresa waya kumhanya;
l nyore nyore kukonzera crosstalk pakati pemasaini;
l inokonzera kuratidzwa pakati pemasaini;
l iyo yekubvisa maimbelform iri nyore kune oscillate nekuwedzera iyo loop nzvimbo yeiyo iripo uye yekunyepedzera kwechiuno.
l iyo radiation kukanganiswa kwenzvimbo inowedzera uye iyo magineti munda munzvimbo inokanganiswa nyore nyore.
l kuwedzera mukana wekusangana nemagineti pamwe nemamwe matunhu ebhodhi;
l iyo yakakwira frequency voltage kudonha pane loop inductor inopa iyo yakajairika-modhi radiation sosi, iyo inogadzirwa kuburikidza neyekunze tambo.
Naizvozvo, PCB Wiring inofanira kunge iri pedyo neende ndere narwo, uye dzivisa kuyambuka-chikamu. Kana zvichidikanwa kuyambuka kupatsanurana kana kuti hazvigone kuve padhuze nepagetsi ivhu remagetsi, aya mamiriro anongobvumidzwa mune yakaderera chiratidzo chiratidzo.
Kugadzirisa pane zvimedu mugadziriro
Kana kuyambuka-chikamu chisingadzivisiki muPCB Dhizaini, maitiro ekuita nazvo? Mune ino kesi, chikamu chezvibvumirano chinoda kugadziriswa kuti ipe nzira pfupi yekudzokera kwechiratidzo. Zviitiko zvakajairika kugadzirisa nzira dzinosanganisira kuwedzera kuchiramba capacitor uye kuyambuka waya we waya.
l Kuchera Capacitor
A 0402 kana 0603 Ceramic Capacitor ne1.01UF kana 0.4UF inowanzoiswa pachiyero chechiratidzo. Kana nzvimbo inobvumirwa, zvimwe zvakawanda zvikoreke capacitors zvinogona kuwedzerwa.
Panguva imwecheteyo, edza kuona kuti waya chiratidzo chiri mukati memhando ye200mi yekusona kwekusona, uye chidiki chinhambwe, zvirinani; Network pamigumo miviri yeakachengeta zvinoenderana neNetwork yeNetwork yendege yereferenti inopfuura iyo zviratidzo zvinopfuura. Ona iyo Networks yakabatana pamigumo miviri yeakapa muchimiro pazasi. Iwo maviri akasiyana maNetwork anoratidzwa mumavara maviri ndeaya:
lBhiriji pamusoro waya waya
Zvakajairika kuti "pasi pokutanga" chiratidzo kuyambuka muparara weSignal Signal Layer,
Yakakwira Speed Signal Wiring Unyanzvi
a)Multilayer Interconnection
Speed Speed Signal Routing Circuit inowanzo kuve nekukwira zvakanyanya
Kusarudzwa zvine musoro kwezviyero kunogona kuderedza zvikuru saizi yebhodhi yekudhinda, kunogona kupfupisa kwazvo nhoo, kunogona kuderedza kwazvo chiratidzo chechiratidzo, chinogona kuderedza kupindira muchinjiko pakati pemasaini, nezvimwe.
b)Iyo isinganyanye kukanda kutungamira, zvirinani
Iyo isingasviki inotungamira ichikotama pakati pemapipi emidziyo yakakwira-mhanya midziyo, zvirinani.
Kutungamira kwinotyisa kwekumhanya-mhanya chiratidzo chinotora dunhu rizere uye rinoda kutendeuka, izvo zvinogona kushandiswa se5 ° polyline kana arc inotendeuka. Ichi chinodiwa chinongoshandiswa chete kugadzirisa iyo yekubata simba reSimbi foil mune yakaderera-frequency redunhu.
Mumatunhu akakwirira
c)Kupfupika kutungamira, zvirinani
Iyo ipfupi inotungamira pakati pemapipi eiyo yakakwira-yekumhanyisa chiratidzo chinomirira dunhu redunhu, zvirinani.
Iyo yakareba iyo inotungamira, iyo yakakura kukosha uye inoparadzanisa kukosha, iyo ichave nekumanikidza kwakawanda pane yakakwirira yeSystem-frequental chiratidzo, asi zvakare kushandura hunhu hwakatemerwa wedunhu, zvichikonzera kuratidzwa uye oscillation yehurongwa.
d)Izvo zvishoma zvinoshandiswa pakati pekutungamira materers, zviri nani
Iyo isinganyanye kupindirana shanduko pakati pemapipi emidziyo yakakwira-yakakwira matunhu, zvirinani.
Iyo inonzi "iyo isinganyanye kupindirana shanduko yekutungamira, zviri nani" zvinoreva kuti maburi mashoma anoshandiswa mukubatana kwezvikamu, zviri nani. Izvo zvakayerwa kuti gomba rimwe chete rinogona kuunza imwe nguva yezana
e)Cherechedzo yakafanana yekuyambuka
Yakakwira-yekumhanyisa chiratidzo chekushandisa inofanirwa kutarisisa kune iyo "yekuvhiringidzika kwekuvhiringidzwa" yakaunzwa neiyo chiratidzo mutsara pfupi chidimbu chekutenderera. Kana kugoverwa kwakafanana hakugone kudzivirirwa, nzvimbo yakakura ye "pasi" inogona kurongwa kune rumwe rutivi rwemutsara wakaenzana chiratidzo kuti uderedze kukanganiswa.
f)Ngwarira matavi uye zvigumbu
Yakakwira-yekumhanyisa chiratidzo chekushandisa inofanirwa kudzivirira kusvetuka kana kugadzira stub.
Zvitunha zvine simba rakakura pane kusakwana uye kunogona kukonzera chiratidzo chekuratidzira uye kuwanda, saka isu tinofanirwa kudzivisa zvigumbuso nematavi mukugadzirwa.
Iyo daisy chain wiring ichaderedza kukanganisa pane chiratidzo.
g)Mitsetse yesainzi inoenda kune iyo Mukati Pours seinogona kuitika
High Frequency Signal mutsara kufamba pamusoro pechiso kuri nyore kuburitsa hombe yemagetsi emagetsi emagetsi, uye zvakare nyore kupindirwa neyekunze electromagnetic radiation kana zvinhu.
Iyo yakakwira frequency sign line yakakundwa nepamhepo inowanikwa uye iyo yaya ya waya, kuburikidza neyekuwedzera kweElectromagnical wave neSower Supply uye Pasi Peturu, iyo radiation yakagadzirwa ichaderedzwa zvakanyanya.
