Ukwakhiwa kwesekethe eguquguqukayo kusetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yezinzuzo zayo eziningi njengokuguquguquka, ukulula, ukubumbana nokuthembeka okuphezulu. Kodwa-ke, njenganoma iyiphi enye intuthuko yezobuchwepheshe, iza nesabelo sayo esifanele sezinselele kanye nezingqinamba.Inselele enkulu ekukhiqizeni isekethe eguquguqukayo ukucindezelwa kwemisebe ye-electromagnetic interference (EMI), ikakhulukazi kumaza aphezulu kanye nezinhlelo zokusebenza ezinesivinini esikhulu. Kulokhu okuthunyelwe kwebhulogi, sizohlola izindlela ezisebenzayo zokubhekana nalezi zinkinga futhi siqinisekise ukusebenza kahle kwamasekhethi aguqukayo.
Ngaphambi kokuthi sijule ngezixazululo, ake siqale siqonde inkinga yamanje. Imisebe ye-electromagnetic kwenzeka lapho izinkambu zikagesi nezizibuthe ezihlotshaniswa nokugeleza kwamandla kagesi zi-oscillate futhi zisakazeka emkhathini. I-EMI, ngakolunye uhlangothi, isho ukuphazamiseka okungathandeki okubangelwa yile misebe ye-electromagnetic. Kuzinhlelo zokusebenza ezinemvamisa ephezulu kanye nesivinini esikhulu, imisebe enjalo kanye nokuphazamiseka kungase kube nomthelela omkhulu ekusebenzeni kwesekhethi eguquguqukayo, kubangele izinkinga zokusebenza, ukunciphisa isignali, ngisho nokwehluleka kwesistimu.
Manje, ake sihlole izixazululo ezisebenzayo zokubhekana nalezi zinkinga ekukhiqizeni isekethe eguquguqukayo:
1. Ubuchwepheshe bokuvikela:
Indlela esebenzayo yokucindezela imisebe ye-electromagnetic kanye ne-EMI ukusebenzisa ubuchwepheshe bokuvikela ekwakhiweni nasekukhiqizeni amasekhethi aguquguqukayo. Ukuvikela kuhilela ukusebenzisa izinto zokuqondisa, njengethusi noma i-aluminium, ukuze udale umgoqo ongokoqobo ovimbela izinkambu zikazibuthe ukuthi zingaphumi noma zingene kusekethe. Ukuvikela okuklanywe kahle kusiza ukulawula ukukhishwa kwegesi ngaphakathi kwamasekhethi futhi kuvimbele i-EMI engafunwa.
2. Ukugawula kanye nokuhlukanisa:
Izindlela ezifanele zokubeka phansi kanye nezokuhlukanisa zibalulekile ekwehliseni imithelela yemisebe ye-electromagnetic. Indiza ephansi noma yamandla ingasebenza njengesihlangu futhi inikeze indlela enezithiyo eziphansi zokugeleza kwamanje, ngaleyo ndlela yehlise amandla e-EMI. Ngaphezu kwalokho, ama-decoupling capacitor angabekwa ngokuhlelekile eduze kwezingxenye zesivinini esikhulu ukuze acindezele umsindo we-high-frequency kanye nokunciphisa umthelela wawo kusekethe.
3. Isakhiwo nokubekwa kwengxenye:
Isakhiwo kanye nokubekwa kwengxenye kufanele kucatshangelwe ngokucophelela ngesikhathi sokukhiqiza i-flex circuit circuit. Izingxenye zesivinini esikhulu kufanele zihlukaniswe zodwa futhi ukulandelelwa kwesignali kufanele kugcinwe kude nemithombo yomsindo engaba khona. Ukunciphisa ubude nendawo eyiluphu yokulandela isignali kunganciphisa kakhulu amathuba emisebe kagesi kanye nezinkinga ze-EMI.
4. Inhloso yesici sokuhlunga:
Ukufaka izingxenye zokuhlunga ezifana nokuklinywa kwemodi evamile, izihlungi ze-EMI, nobuhlalu be-ferrite kusiza ukucindezela imisebe kazibuthe futhi kuhlunge umsindo ongafuneki. Lezi zingxenye zivimba amasignali angafuneki futhi zinikeze i-impedance kumsindo we-high-frequency, ziwuvimbele ukuthi ungaphazamisi umjikelezo.
5. Izixhumi nezintambo zisekelwe kahle:
Izixhumi nezintambo ezisetshenziswa ekwenziweni kwesekethe eguquguqukayo ziyimithombo engaba khona yemisebe ye-electromagnetic kanye ne-EMI. Ukuqinisekisa ukuthi lezi zingxenye zisekelwe kahle futhi zivikelwe kunganciphisa izinkinga ezinjalo. Izihlangu zekhebula eziklanywe ngokucophelela nezixhumi zekhwalithi ephezulu ezinesisekelo esanele zinganciphisa ngempumelelo imisebe kazibuthe kanye nezinkinga ze-EMI.
Ngokufigqiwe
Ukuxazulula izinkinga zemisebe kagesi kanye nezinkinga zokucindezelwa kwe-EMI ekukhiqizeni isekethe eguquguqukayo, ikakhulukazi kuma-high-frequency kanye nezinhlelo zokusebenza ezinesivinini esikhulu, kudinga indlela ehlelekile nephelele. Inhlanganisela yamasu okuvikela, ukubeka phansi okufanelekile kanye nokuqaqa, ukuhlelwa ngokucophelela nokubekwa kwengxenye, ukusetshenziswa kwezingxenye zokuhlunga, nokuqinisekisa ukubekwa phansi okufanele kwezixhumi nezintambo kuyizinyathelo ezibalulekile zokunciphisa lezi zinselele. Ngokusebenzisa lezi zixazululo, onjiniyela nabaklami bangaqinisekisa ukusebenza kahle, ukwethembeka kanye nokusebenza kwamasekethe aguquguqukayo ezinhlelweni ezifunwayo.
