Ingabe ungumthandi we-electronics osafufusa ofuna ukucwila emhlabeni womklamo we-PCB? Ungabe usabheka okunye! Kulo mhlahlandlela wabaqalayo, sizohlola izinyathelo eziyisisekelo zokuklama i-PCB sisebenzisa isofthiwe edumile ye-OrCAD. Noma ngabe ungumfundi, ungumuntu othanda ukuzilibazisa noma uchwepheshe, idizayini ye-PCB eyingcweti izovula umnyango wamathuba angapheli. Ngakho-ke, ake siqale.
1. Yazi okuyisisekelo:
Ngaphambi kokungena enqubweni yokuklama, zijwayeze nezisekelo zama-PCB. I-PCB isifinyezo sebhodi lesifunda eliphrintiwe, eliyingxenye ebalulekile yemishini kagesi. Isekela futhi ixhume ngogesi izingxenye ezihlukahlukene ze-elekthronikhi. Ukuqonda okuqinile kwezinhlelo zesekethe, izingxenye kanye nesakhiwo sazo.
2. Khetha i-OrCAD:
I-OrCAD evela ku-Cadence Design Systems iyithuluzi lesofthiwe elihamba phambili elisetshenziswa kabanzi ekwakheni i-PCB. Ihlinzeka ngesethi ephelele yamathuluzi wokuthwebula isikimu, ukubekwa kwengxenye kanye nomzila. Landa futhi ufake isofthiwe ye-OrCAD kukhompyutha yakho ukuze uqalise.
3. Ukuthwebula okuhleliwe:
Qala uhambo lwakho lokuklama ngokwakha isikimu nge-OrCAD Capture. Leli thuluzi likuvumela ukuthi udwebe ukuxhumana kwesifunda, engeza izingxenye futhi uchaze izakhiwo zabo zikagesi. Qinisekisa ukukhetha okulungile kwezimpawu nokuxhumana phakathi kwezingxenye ngazinye.
4. Ukubekwa kwengxenye:
Uma isikimu sesiphelile, dlulela esinyathelweni esilandelayo: ukubekwa kwengxenye. Umklami we-OrCAD PCB uhlinzeka ngamathuluzi okubeka izingxenye kusakhiwo se-PCB. Cabangela izici ezifana nokuba seduze kwengxenye, ubuqotho besignali, nobude bokulandelela obuthuthukisiwe lapho ubeka izingxenye. Ukubekwa kwamasu kuqinisekisa umzila osebenzayo futhi kunciphisa ukuphazamiseka kwesignali okungaba khona.
5. Umzila:
Manje isixhumanisi esibaluleke kakhulu ekwakhiweni kwe-PCB - isigaba somzila. Amandla omzila we-OrCAD akuvumela ukuthi udale imikhondo yethusi exhuma izingxenye ezahlukahlukene ku-PCB. Umzila ofanele uqinisekisa ubuqotho besignali futhi unciphisa umsindo nokuphazamiseka. Imithetho yedizayini efana nesikhala sokuvula kanye nokushuba komkhondo kufanele kulandelwe ukuze kuqinisekiswe ukusebenza okufanele.
6. Ubuqotho besignali kanye nokuhlola kwe-DRC:
Sebenzisa amathuluzi e-SI akhelwe ngaphakathi e-OrCAD ukuze wenze ukuhlola kobuqotho besignali (SI) ngaphambi kokuphothula umklamo wakho. Lokhu kuhlola kukhomba ukuphazamiseka kwesignali okungaba khona noma izibonisi ezingase zithinte ukusebenza kukonke. Futhi, yenza ukuhlola komthetho wokuklama (i-DRC) ukuze uqinisekise ukuthobela imihlahlandlela yokukhiqiza kanye nezingqinamba zikagesi.
7. Ukuqinisekiswa Kwedizayini:
Uma umklamo we-PCB usuqediwe, inqubo yokuqinisekisa ephelele iyadingeka. Hlola idizayini ukuze uthole amaphutha, afaka izikhindi, okuvulayo, nanoma yiziphi ezinye izinkinga. Hlola ukulebula kwengxenye okulungile, ukucaca kombhalo, nokuvumelana kuzo zonke izendlalelo. Ukuqinisekisa ukunemba kubalulekile ngaphambi kokuqhubeka nokukhiqiza.
8. Thumela futhi wenze:
Uma usunelisekile ngomklamo, thumela isakhiwo se-PCB kufomethi evamile njenge-Gerber RS-274X. Le fomethi yamukelwa kabanzi ngabakhiqizi be-PCB. Khiqiza amafayela ahlukene wesendlalelo ngasinye, okuhlanganisa imikhondo yethusi, imaski ye-solder, nezimbobo ezibhoboziwe. Abakhiqizi bazosebenzisa lawa mafayela ukuze bakhe i-PCB ebonakalayo.
Ukuklama i-PCB nge-OrCAD kungase kubonakale kunzima ekuqaleni, kodwa ngokuzijwayeza nokuphikelela kungaba umzamo ojabulisayo nozuzisayo. Khumbula ukuqala ngezinto eziyisisekelo, khetha amathuluzi esofthiwe alungile, bese ulandela indlela ehlelekile. Idizayini ye-PCB iyinqubo yokufunda eqhubekayo, ngakho qhubeka uhlola ubuchwepheshe obuthuthukile ngenkathi uthola ulwazi. Pho kungani ulinda? Vula ubuhlakani bakho bese uqala ukuklama ama-PCB akho nge-OrCAD namuhla!
