Ibhodi lesifunda le-PCB lingahlanganisa izingxenye eziningi ze-elekthronikhi ndawonye, ​​​​ezingonga isikhala kahle kakhulu futhi ngeke zivimbele ukusebenza kwesekethe. Kunezinqubo eziningi ekwakhiweni kwebhodi lesifunda le-PCB. Okokuqala, sidinga ukusetha Hlola imingcele yebhodi lesifunda le-PCB. Okwesibili, sidinga ukufaka izingxenye ezihlukahlukene ezindaweni zazo ezifanele.

1. Faka isistimu yokuklama ye-PCB bese usetha imingcele efanele

Setha imingcele yemvelo yohlelo lokuklama ngokwemikhuba yomuntu siqu, njengosayizi nohlobo lwephoyinti legridi, usayizi nohlobo lwekhesa, njll. Ngokuvamile, inani elimisiwe lesistimu lingasetshenziswa. Ngaphezu kwalokho, imingcele efana nobukhulu kanye nenani lezingqimba zebhodi lesifunda kufanele zisethwe.

2. Khiqiza ithebula lenethiwekhi elingenisiwe

Ithebula lenethiwekhi ibhuloho kanye nesixhumanisi phakathi komklamo wohlelo lwesifunda kanye nomklamo webhodi lesifunda eliphrintiwe, okubaluleke kakhulu. Uhlu lwenethi lungakhiqizwa kusukela kumdwebo wohlelo lwesekethe, noma lungakhishwa kufayela lebhodi lesekethe elikhona eliphrintiwe. Lapho ithebula lenethiwekhi yethulwa, kuyadingeka ukuhlola nokulungisa amaphutha ekwakhiweni kwesikimu sesifunda.

3. Hlela indawo yephakheji ngayinye yengxenye

Umsebenzi wokuhlela othomathikhi wesistimu ungasetshenziswa, kodwa umsebenzi wokuhlela othomathikhi awuphelele, futhi kuyadingeka ukulungisa mathupha isikhundla sephakheji ngayinye yengxenye.

4. Yenza izintambo zebhodi lesifunda

Isisekelo somzila ozenzakalelayo webhodi lesifunda ukusetha ibanga lokuphepha, ifomu lezintambo nokunye okuqukethwe. Njengamanje, umsebenzi we-wiring othomathikhi wemishini usuphelele, futhi umdwebo wesifunda jikelele ungahanjiswa; kodwa ukuhlelwa kweminye imigqa akugculisi, futhi izintambo zingenziwa ngesandla.

5. Londoloza ngokukhipha iphrinta noma ikhophi eqinile

Ngemva kokuqeda izintambo zebhodi lesifunda, gcina ifayela lomdwebo wesifunda eliqediwe, bese usebenzisa amadivaysi ahlukahlukene okukhipha imifanekiso, njengamaphrinta noma ama-plotter, ukuze ukhiphe umdwebo wezintambo webhodi lesifunda.

Ukuhambisana kwe-electromagnetic kubhekisela emandleni emishini kagesi ukuze isebenze ngokuzwana nangempumelelo ezindaweni ezihlukahlukene ze-electromagnetic. Inhloso ukunika amandla okokusebenza kwe-elekthronikhi ukucindezela iziphazamiso ezahlukahlukene zangaphandle, ukunika amandla okokusebenza kwe-elekthronikhi ukuthi kusebenze ngokujwayelekile endaweni ethile kazibuthe kagesi, futhi ngasikhathi sinye kwehlise ukugxambukela kozibuthe kwemishini kagesi ngokwayo kwezinye izinto zikagesi. Njengomhlinzeki wokuxhunywa kukagesi wezingxenye ze-elekthronikhi, uyini ukwakheka kokuhambisana kwebhodi lesekethe le-PCB?

1. Khetha ububanzi bentambo obunengqondo. Njengoba ukuphazamiseka komthelela okukhiqizwa amandla esikhashana emigqeni ephrintiwe yebhodi lesekethe le-PCB kubangelwa ikakhulukazi ingxenye ye-inductance yocingo oluphrintiwe, ukufakwa kwentambo ephrintiwe kufanele kuncishiswe.

2. Ngokusho kobunzima besekethe, ukukhetha okunengqondo kwenombolo yesendlalelo se-PCB kunganciphisa ngempumelelo ukuphazanyiswa kwe-electromagnetic, kunciphise kakhulu ivolumu ye-PCB nobude be-loop yamanje kanye nezintambo zegatsha, futhi kunciphise kakhulu ukuphazamiseka phakathi kwamasignali.

3. Ukwamukela isu le-wiring elilungile kanye nokusebenzisa izintambo ezilinganayo kunganciphisa inductance yezintambo, kodwa i-inductance mutual kanye nokusabalalisa amandla phakathi kwezintambo kuzokhula. Uma ukwakheka kuvuma, kungcono ukusebenzisa isakhiwo sezintambo ezinezikhala ezimise kahle. Indlela ethize iwukwenza uhlangothi olulodwa lwebhodi eliphrintiwe I-Wiring enezingqimba, izintambo ngakolunye uhlangothi zibheke phezulu, bese ixhuma ngezimbobo ezinensimbi ezimbobeni eziphambanayo.

4. Ukuze ucindezele i-crosstalk phakathi kwezintambo zebhodi lesifunda le-PCB, zama ukugwema izintambo ezilinganayo ezikude lapho uklama izintambo, futhi ugcine ibanga phakathi kwezintambo ngangokunokwenzeka. isiphambano. Ukusetha umugqa ophrintiwe osekelwe phakathi kwemigqa yesignali ezwela kakhulu ekuphazamisekeni kungacindezela ngempumelelo i-crosstalk
