Ukucatshangelwa kokuthobela kwe-EMI/EMC kumabhodi esekethe aguquguqukayo aqinile

Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngokucatshangelwa kokuhambisana kwe-EMI/EMC kwamabhodi wesifunda aqinile-flex nokuthi kungani kufanele kubhekwane nawo.

Ukuqinisekisa ukuthobelana nokuphazanyiswa kwe-electromagnetic interference (EMI) kanye ne-electromagnetic comppatibility (EMC) kubalulekile kumadivaysi kagesi kanye nokusebenza kwawo. Ngaphakathi kwemboni ye-PCB (Printed Circuit Board), amabhodi esekethe aqinile ayindawo ethile edinga ukucatshangelwa ngokucophelela nokunaka imininingwane. Lawa mabhodi ahlanganisa izinzuzo zamasekethe aqinile futhi aguquguqukayo, okwenza kube ukukhetha okudumile kwezinhlelo zokusebenza lapho isikhala silinganiselwe futhi ukuqina kubalulekile.

Ukucatshangelwa okuyinhloko ukuze kuzuzwe ukuthobela kwe-EMI/EMC kumabhodi esekethe e-rigid-flex kuwukusekela okufanele.Izindiza eziphansi kanye nokuvikela kufanele kuklanywe ngokucophelela futhi kubekwe ukuze kuncishiswe imisebe ye-EMI futhi kukhuliswe ukuvikeleka kwe-EMC. Kubalulekile ukudala indlela ephansi ye-impedance ye-EMI yamanje nokunciphisa umthelela wayo kumjikelezo. Ngokuqinisekisa uhlelo oluqinile lwesisekelo kulo lonke ibhodi lesifunda, ingozi yezinkinga ezihlobene ne-EMI ingancishiswa kakhulu.

Esinye isici okufanele sicatshangelwe ukubekwa kanye nomzila wamasignali anesivinini esikhulu. Amasignali anezikhathi zokukhuphuka nokuwa ngokushesha asengozini enkulu emisebeni ye-EMI futhi angase aphazamise ezinye izingxenye ebhodini.Ngokuhlukanisa ngokucophelela amasiginali anesivinini esikhulu ezingxenyeni ezizwelayo njengamasekhethi e-analog, ubungozi bokuphazamiseka bungancishiswa. Ukwengeza, ukusetshenziswa kwezindlela zokubonisa umehluko kungathuthukisa ukusebenza kwe-EMI/EMC ngoba zinikeza ukungavikeleki komsindo okungcono uma kuqhathaniswa nezimpawu eziphelayo.

Ukukhethwa kwengxenye nakho kubalulekile ekuthotshelweni kwe-EMI/EMC kumabhodi esekethe aguquguqukayo.Ukukhetha izingxenye ezinezici ezifanele ze-EMI/EMC, ezifana nokukhishwa kwe-EMI ephansi kanye nokuvikeleka okuhle kokuphazanyiswa kwangaphandle, kungathuthukisa kakhulu ukusebenza kwebhodi kukonke. Izingxenye ezinamakhono akhelwe ngaphakathi e-EMI/EMC, njengezihlungi ezihlanganisiwe noma ukuvikela, zingaqhubeka zenze inqubo yokuklama ibe lula futhi ziqinisekise ukuhambisana nezindinganiso zokulawula.

Ukwahlukanisa okufanele nokuvikela nakho kubalulekile. Emabhodini esekethe aqinile-aguquguqukayo, izingxenye eziguquguqukayo zingenwa yingcindezi yemishini futhi zingenwa kalula emisebeni ye-EMI.Ukuqinisekisa ukuthi izingxenye eziguquguqukayo zivikelwe ngokwanele futhi zivikelwe kungasiza ukuvimbela izinkinga ezihlobene ne-EMI. Ukwengeza, ukwahlukanisa okufanele phakathi kwezendlalelo ze-conductive namasignali kunciphisa ubungozi be-crosstalk nokuphazamiseka kwesignali.

Abaqambi kufanele futhi banake ukwakheka okuphelele nokunqwabelana kwamabhodi aqinile-flex. Ngokuhlela ngokucophelela izendlalelo nezingxenye ezihlukene, ukusebenza kwe-EMI/EMC kungalawuleka kangcono.Izendlalelo zesignali kufanele zihlanganiswe phakathi kwezingqimba zomhlabathi noma zamandla ukuze kuncishiswe ukuhlangana kwesignali futhi kuncishiswe ubungozi bokuphazamiseka. Ukwengeza, ukusebenzisa imihlahlandlela yokuklama ye-EMI/EMC nemithetho kungasiza ukuqinisekisa ukuthi isakhiwo sakho sihlangabezana nezidingo zokuthobelana.

Ukuhlola nokuqinisekisa kudlala indima ebalulekile ekuzuzeni ukuthobela kwe-EMI/EMC kumabhodi esekethe aguquguqukayo.Ngemva kokuba umklamo wokuqala usuqediwe, kufanele kwenziwe ukuhlolwa okuphelele ukuze kuqinisekiswe ukusebenza kwebhodi. Ukuhlolwa kokuphuma kwe-EMI kulinganisa inani lemisebe kagesi ekhishwa ibhodi lesifunda, kuyilapho ukuhlolwa kwe-EMC kuhlola ukungatheleleki kwayo ekuphazamisekeni kwangaphandle. Lokhu kuhlola kungasiza ekuboneni noma yiziphi izinkinga futhi kuvumele ukuguqulwa okudingekayo ukuze kwenziwe ukuze kutholwe ukuthobelana.

Ngokufigqiwe, ukuqinisekisa ukuthobela kwe-EMI/EMC kwamabhodi esekethe aqinile-flex kudinga ukucatshangelwa ngokucophelela kwezici ezihlukahlukene. Kusukela ekusekelweni okufanele kanye nokukhetha kwengxenye ukuya ekuboniseni umzila nokuhlola, isinyathelo ngasinye sidlala indima ebalulekile ekuzuzeni ibhodi elihlangabezana nezindinganiso zokulawula. Ngokubhekana nalokhu kucatshangelwa nokulandela izinqubo ezingcono kakhulu, abaklami bangakha amabhodi esekethe aqinile nanokwethenjelwa asebenza kahle ezindaweni ezinokucindezeleka okukhulu ngenkathi ehlangabezana nezidingo ze-EMI/EMC.
