I-PCB Design

PCB design

Isoftware

1. Isofthiwe esetshenziswa kakhulu e-China kukhona i-Protel, i-Protel 99se, i-Protel DXP, i-Altium, iphuma enkampanini efanayo futhi ihlale ithuthukiswa;inguqulo yamanje i-Altium Designer 15 elula kakhulu, idizayini iyinto evamile, kodwa ayilungile kakhulu kuma-PCB ayinkimbinkimbi.

2. I-Cadence SPB.Inguqulo yamanje yiCadence SPB 16.5;idizayini yeskimu ye-ORCAD iyindinganiso yamazwe ngamazwe;Idizayini ye-PCB nokulingisa kuphelele kakhulu.Kunzima kakhulu ukusebenzisa kuneProtel.Izidingo eziyinhloko zikuzilungiselelo eziyinkimbinkimbi.;Kodwa kunemithetho yokuklama, ngakho-ke umklamo uphumelela kakhulu, futhi unamandla kakhulu kune-Protel.

3. I-Mentor's BORDSTATIONG kanye ne-EE, BOARDSTATION isebenza kuphela ohlelweni lwe-UNIX, olungakhelwe i-PC, ngakho bambalwa abantu abalusebenzisayo;inguqulo yamanje ye-Mentor EE ithi i-Mentor EE 7.9, isezingeni elifanayo ne-Cadence SPB, amandla ayo wucingo oludonsayo nocingo olundizayo.Ibizwa nge-flying wire king.

4. UKHOZI.Lena isofthiwe ye-PCB esetshenziswa kakhulu kunazo zonke eYurophu.I-PCB design software okukhulunywe ngayo ngenhla isetshenziswa kakhulu.I-Cadence SPB kanye ne-Mentor EE bangamakhosi afaneleka kahle.Uma kuyi-PCB esaqalayo yokuklama, ngicabanga ukuthi i-Cadence SPB ingcono, ingahlakulela umkhuba omuhle wokuklama womklami, futhi ingaqinisekisa ikhwalithi enhle yokuklama.

Amakhono ahlobene

Amathiphu okusetha

Umklamo udinga ukusethwa ezindaweni ezihlukahlukene ngezigaba ezahlukene.Esigabeni sesakhiwo, amaphuzu egridi amakhulu angasetshenziselwa ukwakheka kwedivayisi;

Kumadivayisi amakhulu afana nama-IC nezixhumi ezingamisi, ungakhetha ukunemba kwegridi okungu-50 kuya ku-100 mils ngesakhiwo.Kumadivayisi amancane angenzi lutho njengama-resistors, ama-capacitor, nama-inductors, ungasebenzisa ama-25 mils ngesakhiwo.Ukunemba kwamaphoyinti egridi amakhulu kuhambisana nokuqondanisa kwedivayisi nobuhle besakhiwo.

Imithetho yesakhiwo se-PCB:

1. Ngaphansi kwezimo ezijwayelekile, zonke izingxenye kufanele zibekwe endaweni efanayo yebhodi lesifunda.Kuphela uma izingxenye zesendlalelo esiphezulu ziminyene kakhulu, lapho ezinye izisetshenziswa ezinomkhawulo ophezulu kanye nezishisi kancane, njengezihluthulelo ze-chip, ama-chip capacitor, ukunamathisela ama-Chip ICs zibekwe kungqimba olungezansi.

2. Ngokwesisekelo sokuqinisekisa ukusebenza kukagesi, izingxenye kufanele zibekwe kugridi futhi zihlelwe ngokuhambisana noma i-perpendicular komunye nomunye ukuze zibe zinhle futhi zihle.Ngaphansi kwezimo ezijwayelekile, izingxenye azivunyelwe ukugqagqana;izingxenye kufanele zihlelwe ngokuhlangene, futhi izingxenye kufanele zibe kuso sonke isakhiwo Ukusabalalisa okufanayo kanye nokuminyana okufanayo.

3. Isikhala esincane phakathi kwamaphethini ephedi asondelene ezingxenyeni ezahlukene ebhodini lesekethe kufanele sibe ngaphezu kuka-1MM.

4. Ivamise ukuba kude no-2MM onqenqemeni lwebhodi lesekethe.Isimo esihle kakhulu sebhodi lesifunda singunxande, sinesilinganiso sobude nobubanzi buka-3: 2 noma 4: 3. Uma usayizi webhodi mkhulu kuno-200MM ngo-150MM, ukufinyeleleka kwebhodi lesifunda kufanele kubhekwe amandla omshini.

Amakhono wesakhiwo

Ekwakhiweni kwesakhiwo se-PCB, iyunithi yebhodi lesifunda kufanele ihlaziywe, ukwakheka kwesakhiwo kufanele kusekelwe emsebenzini, futhi ukuhlelwa kwazo zonke izingxenye zesekethe kufanele kuhlangabezane nemigomo elandelayo:

1. Hlela indawo yeyunithi ngayinye yesekethe esebenzayo ngokusho kokugeleza kwesekethe, yenza ukwakheka kube lula ukujikeleza kwesignali, futhi ugcine isignali ngendlela efanayo ngangokunokwenzeka.

2. Ngezingxenye eziyinhloko zeyunithi ngayinye esebenzayo njengesikhungo, isakhiwo esimzungezile.Izingxenye kufanele zilingane, zihlanganiswe futhi zihleleke kahle ku-PCB ukuze kuncishiswe futhi kufinyezwe umkhondo nokuxhumana phakathi kwezingxenye.

3. Kumasekhethi asebenza kuma-frequencies aphezulu, imingcele yokusabalalisa phakathi kwezingxenye kufanele icatshangelwe.Isifunda esijwayelekile kufanele sihlele izingxenye ngokuhambisana ngangokunokwenzeka, okungeyona nje enhle kuphela, kodwa futhi kulula ukuyifaka kanye ne-solder, futhi kulula ukukhiqiza ngobuningi.

Izinyathelo zokuklama

Idizayini yesakhiwo

Ku-PCB, izingxenye ezikhethekile zibhekisela ezingxenyeni ezibalulekile engxenyeni ye-high-frequency, izingxenye eziyinhloko kusekethe, izakhi eziphazamiseka kalula, izakhi ezinamandla kagesi aphezulu, izakhi ezikhiqiza ukushisa okukhulu, nezinye izakhi zobulili obuhlukile. Indawo yalezi zingxenye ezikhethekile kudingeka ihlaziywe ngokucophelela, futhi isakhiwo sidinga ukuhlangabezana nezidingo zomsebenzi wesifunda kanye nezidingo zokukhiqiza.Ukubekwa kwazo ngendlela engafanele kungase kubangele izinkinga zokusebenzisa isifunda kanye nezinkinga zobuqotho besignali, okungaholela ekwahluleleni komklamo we-PCB.

Lapho ubeka izingxenye ezikhethekile ekwakhiweni, qala ucabangele usayizi we-PCB.Uma ubukhulu be-PCB bukhulu kakhulu, imigqa ephrintiwe yinde, i-impedance iyanda, ikhono lokulwa nokumisa liyancipha, futhi izindleko nazo ziyanda;uma kuncane kakhulu, ukuchithwa kokushisa akukuhle, futhi imigqa eseduze iphazamisa kalula.Ngemva kokunquma usayizi we-PCB, thola indawo ye-pendulum yengxenye ekhethekile.Ekugcineni, ngokusho kweyunithi yokusebenza, zonke izingxenye zesifunda zibekwe.Indawo yezingxenye ezikhethekile kufanele ngokuvamile ibheke imigomo elandelayo ngesikhathi sokuhlela:

1. Nciphisa ukuxhumana phakathi kwezingxenye zemvamisa ephezulu ngangokunokwenzeka, zama ukunciphisa imingcele yazo yokusabalalisa kanye nokuphazanyiswa kwe-electromagnetic mutual.Izingxenye ezithintekayo azikwazi ukusondelana kakhulu, futhi okokufaka nokukhiphayo kufanele kube kude ngangokunokwenzeka.

2 Ezinye izingxenye noma izintambo zingase zibe nomehluko omkhulu ongaba khona, futhi ibanga lazo kufanele linyuswe ukuze kugwenywe amasekhethi amafushane ngengozi okubangelwa ukuphuma.Izingxenye zamandla kagesi aphezulu kufanele zigcinwe lapho zingafinyeleleki.

3. Izingxenye ezinesisindo esingaphezu kwe-15G zingalungiswa kubakaki bese zishiselwa.Lezo zingxenye ezisindayo nezishisayo akufanele zibekwe ebhodini lesifunda kodwa kufanele zibekwe epuleti eliphansi le-chassis eyinhloko, futhi ukuchithwa kokushisa kufanele kucatshangelwe.Izingxenye ezishisayo kufanele zigcinwe kude nezingxenye zokushisa.

4. Isakhiwo sezingxenye ezilungisekayo ezifana ne-potentiometer, amakhoyili e-inductance alungisekayo, ama-variable capacitor, ama-micro switch, njll. kufanele kucabangele izidingo zesakhiwo salo lonke ibhodi.Amanye amaswishi asetshenziswa njalo kufanele kube Yibeke lapho ongafinyelela khona kalula ngezandla zakho.Isakhiwo sezingxenye sinokulinganisela, siminyene futhi siminyene, hhayi phezulu-sisindayo.

Enye yempumelelo yomkhiqizo ukunaka ikhwalithi yangaphakathi.Kodwa kuyadingeka ukucabangela ubuhle obuphelele, kokubili amabhodi aphelele, ukuze abe umkhiqizo ophumelelayo.

Ukulandelana

1. Beka izingxenye ezifanelana eduze nesakhiwo, njengamasokhethi amandla, izibani zezinkomba, amaswishi, izixhumi, njll.

2. Beka izingxenye ezikhethekile, njengezingxenye ezinkulu, izingxenye ezisindayo, izingxenye zokufudumeza, ama-transformer, ama-IC, njll.

3. Beka izingxenye ezincane.

Ukuhlola isakhiwo

1. Ukuthi usayizi webhodi lesifunda nemidwebo iyahlangabezana yini nobukhulu bokucubungula.

2. Ukuthi ukwakheka kwezingxenye kuyalingana, kuhlelwe kahle, nokuthi zonke zibekwe obala.

3. Ingabe kukhona ukungqubuzana kuwo wonke amazinga?Okufana nokuthi izingxenye, uhlaka lwangaphandle, kanye nezinga elidinga ukuphrinta kwangasese kunengqondo.

3. Ukuthi izingxenye ezivame ukusetshenziswa zikulungele yini ukuzisebenzisa.Okufana namaswishi, ama-plug-in amabhodi afakwe emishinini, izakhi okufanele zishintshwe njalo, njll.

4. Ingabe ibanga phakathi kwezingxenye ezishisayo kanye nezingxenye zokufudumeza linengqondo?

5. Ukuthi ukuchithwa kokushisa kuhle yini.

6. Ngabe inkinga yokugxambukela komugqa idinga ukubhekwa.
