Ocwaningweni lwe PCB ubuchwepheshe obubuyela emuva, umdwebo wokuphinda uhlehlise ubhekisa emuva kumdwebo wefayela le-PCB noma umdwebo wesifunda we-PCB odonswe ngqo ngokuya ngento ebonakalayo yomkhiqizo, ukuze uchaze umgomo nesimo sokusebenza kwebhodi lesifunda. Ngaphezu kwalokho, umdwebo wesifunda nawo usetshenziselwa ukuhlaziya izici ezisebenzayo zomkhiqizo uqobo. Ekuklanyeni okuphambili, ukuthuthukiswa komkhiqizo jikelele kufanele kuqala kusebenze ukwakheka okuhlelekile, bese kwenziwa i-PCB design ngokuya ngomklamo wesikimu.

I-schematic ye-PCB inendima ekhethekile, noma ngabe isetshenziselwa ukuhlaziya izimiso zebhodi lesifunda kanye nezici zokusebenza komkhiqizo ekutadisheni okuphambene nalokho, noma njengesisekelo nesisekelo sokwakhiwa kwe-PCB ekuklanyeni phambili. Ngakho-ke, ungayihlehlisa kanjani i-PCB schematic, futhi imiphi imininingwane inqubo ebuyela emuva okufanele iyinake, ngokuya ngemibhalo noma ngezinto zangempela?

1. Hlukanisa ngokufanele izindawo zokusebenza

Lapho umdwebo wesikimu webhodi le-PCB waklanywa kabusha, ukwahlukaniswa okunengqondo kwezindawo ezisebenzayo kungasiza onjiniyela banciphise izinkinga ezingadingekile futhi bathuthukise ukusebenza kahle komdwebo.Ngokuvamile, izingxenye ezinomsebenzi ofanayo ku-PCB zizohlelwa ngendlela eyodwa, futhi indawo ehlukanisayo yokusebenza ingaba nesisekelo esikahle futhi esinembile lapho uhlelo luhlehlisiwe. Kodwa-ke, ukuhlukaniswa kwale ndawo esebenzayo akuyona into engqubuzanayo. Kudinga onjiniyela ukuthi babe nokuqonda okuthile kolwazi oluhlobene nesekethe lwe-elekthronikhi. Okokuqala, thola izingxenye ezisemqoka kuyunithi esebenzayo, bese ngokuya ngokuxhumeka kokulandela, thola ezinye izingxenye zophiko olufanayo olusebenzayo, bese wenza ukwahlukanisa okusebenzayo. Ukwakheka kokuhlukaniswa okusebenzayo kuyisisekelo sesikimu. Futhi, ungakhohlwa ukusebenzisa izinombolo ze-serial ebhodini ngesikhathi senqubo, ezingakusiza ukwahlukanisa ukusebenza ngokushesha.

2. Thola izilinganiso

Le nkomba kungabuye kuthiwe yingxenye eyinhloko yebhodi lekhophi le-PCB ekuqaleni komdwebo wesikimu. Ngemuva kokuthi izingxenye zezethenjwa zikhonjwe, ukudweba ngokuya ngezikhonkwane zalezi zingxenye zezithenjwa kungaqinisekisa ukunemba komdwebo wesikimu ngezinga elikhulu. Ukuzimisela kwengxenye yesethenjwa akuyona inkinga eyinkimbinkimbi kakhulu konjiniyela. Imvamisa, into edlala indima enkulu esifundeni ingakhethwa njengengxenye yesethenjwa. Imvamisa iba mikhulu futhi inezikhonkwane eziningi, okulula ukuzelula. Njengamasekethe ahlanganisiwe, ama-transformer, ama-transistors, njll. Angasebenza njengesethenjwa esifanelekile.

3, behlukanisa kahle imigqa, umugqa ofanele

Ukuze uhlukanise imigqa yaphansi, yamandla nezimpawu, onjiniyela futhi kudingeka babe nolwazi lokuphakelwa kwamandla, ukuxhumeka kwesifunda, i-PCB wiring nokunye. Umehluko phakathi kwalezi zintambo ungahlaziywa kusukela ekuxhumaneni kwezinto, ububanzi bezinhlamvu zethusi esifundeni, kanye nezici ze-elektroniki uqobo. Kumidwebo yezintambo, izintambo zomhlaba zingasetshenziswa enanini elikhulu lezimpawu zomhlaba ukugwema ukweqa nokusabalalisa imigqa. Imigqa ingahlukaniswa ngokucacile ngokusebenzisa imigqa ehlukene ngemibala ehlukene, futhi izimpawu ezikhethekile zingasetshenziselwa izingxenye ezahlukahlukene, futhi noma amasekethe amayunithi angadonselwa ngawodwana futhi ekugcineni ahlanganiswe.

4. Yazi kahle uhlaka oluyisisekelo bese ubheka imidwebo efanayo yesikimu

Kwezinye izindlela eziyisisekelo zohlaka lwe-elekthronikhi nezindlela zokudweba zomthetho, onjiniyela kudingeka bazi kahle, hhayi nje kuphela ukudweba ngqo ukwakheka okuyisisekelo kwesekethe elithile elilula futhi elijwayelekile, kepha futhi kwakha uhlaka oluphelele lwesekethe kagesi. Ngakolunye uhlangothi, ungazibi imikhiqizo efanayo ye-elekthronikhi kumbhalo wesikimu sebhodi yamakhophi we-PCB inokufana okuthile. Onjiniyela bangasebenzisa ngokugcwele ama-schematics afanayo ukwenza okuphambene nesikimu esisha somkhiqizo ngokuya ngesipiliyoni.

5. Hlola nokwandisa

Ngemuva kokuqeda uhlelo, kufanele uhlehlise ukuklama uhlelo lwe-PCB ngokuhlola nokuhlola izixhumanisi. Amanani wokuqokwa wezinto ezizwela kumapharamitha wokusabalalisa we-PCB adinga ukubhekwa futhi alungiselelwe. Ngokusho komdwebo wefayela le-PCB, umdwebo ohleliwe uqhathaniswa futhi uyahlaziywa ukuze kuqinisekiswe ukuthi umdwebo ohleliwe ufana ncamashi nomdwebo wefayela. Uma ukwakheka kohlelo kutholakala ukuthi akuhlangabezani nezidingo ngesikhathi sokuhlolwa, uhlelo luzolungiswa luze lube nencazelo ephelele, yenziwe ifane, inembile futhi icace.
