I-Characteristic Impedance Control PCB

Ukuphazamiseka kwesici komqhubi we-PCB kuyinkomba ebalulekile yokwakhiwa kwesekethe, ikakhulukazi ekwakhiweni kwe-PCB yesekethe yefrikhwensi ephezulu, kufanele sicabangele ukuthi ukungasebenzi kahle kwesici somqhubi kuyahambisana yini nokungasebenzi kahle kwesici kudingwa idivayisi noma isiginali.

Ukufanisa kwe-PCB Impedance

Ku-PCB, uma kukhona ukudluliswa kwesignali, kulindeleke ukuthi kube kusukela ekupheleni kokuthumela kwamandla kagesi, esimweni sokulahlekelwa okuncane kwamandla, kungadluliselwa ngokushelela ekupheleni kokwamukela, futhi ukuphela kokuthola kuzomuncwa ngokuphelele. ngaphandle kokucabanga.Ukuze kuzuzwe lokhu kudluliswa, i-impedance kulayini kufanele ilingane ne-impedance ngaphakathi kwesiphetho esisuka kuyo ukuze kubizwe nge-impedance matching.Ukufaniswa kwe-impedance kungenye yezinto zokuklama lapho uklama isifunda se-PCB esinesivinini esikhulu.Inani le-impedance lihlobene ngokuphelele nemodi yomzila.

Isibonelo, noma ngabe uhamba phezu kwesendlalelo esingaphezulu (i-Microstrip) noma isendlalelo sangaphakathi (I-Stripline/I-Double Stripline), ibanga ukusuka kusendlalelo samandla esithenjwa noma isendlalelo, ububanzi bomzila, okokusebenza kwe-PCB, njll., konke kuthinta ukubaluleka kwesici sokuvimbela umzila.Okusho ukuthi, inani le-impedance linganqunywa kuphela ngemuva kokufakwa kwezintambo, futhi i-impedance yesici ekhiqizwa abakhiqizi abahlukene be-PCB nayo iyahluka kancane.Ngokuvamile, isofthiwe yokulingisa ngeke ikwazi ukucabangela ukuvinjelwa kwezintambo ezingaqhubeki ngenxa yokulinganiselwa kwemodeli yomugqa noma i-algorithm yezibalo esetshenzisiwe.

Ngalesi sikhathi, ama-Temninator athile kuphela angagodlwa kumdwebo wohlelo, njengokumelana nochungechunge, ukuze kuncishiswe umphumela ongaqhubeki wokuvinjelwa kwezintambo.Isixazululo sangempela esiyisisekelo senkinga ukuzama ukugwema ukwenzeka kokunqanyulwa kwe-impedance lapho ufaka izintambo.
