Mafungiro eEMI/EMC kutevedzera mune rigid flex redunhu mabhodhi

Mune ino blog post, isu tichakurukura iyo EMI/EMC yekuteedzera kufunga kweakaomesesa-flex edunhu mabhodhi uye nei achifanira kugadziriswa.

Kuve nechokwadi chekutevedzera kukanganiswa kwemagetsi (EMI) uye electromagnetic kuenderana (EMC) zviyero zvakakosha pamidziyo yemagetsi nekuita kwayo.Mukati mePCB (Printed Circuit Board) indasitiri, akaomesesa-flex edunhu mabhodhi inzvimbo chaiyo inoda kunyatsotariswa uye kutarisisa kune zvakadzama.Aya mabhodhi anosanganisa mabhenefiti eakaomarara uye anochinjika maseketi, achiaita sarudzo yakakurumbira kune maapplication uko nzvimbo ishoma uye kusimba kwakakosha.

Iko kutariswa kwekutanga kwekuwana EMI/EMC kutevedzera mune rigid-flex redunhu mabhodhi ndiko kudzika kwakakodzera.Ndege dzepasi nekudzivirira dzinofanirwa kunyatsogadzirwa uye kuiswa kuti dzideredze EMI radiation uye kuwedzera EMC dziviriro.Izvo zvakakosha kugadzira yakaderera-impedance nzira yeEMI ikozvino uye kuderedza maitiro ayo padunhu.Nekuve nechokwadi cheiyo yakasimba yepasi system mubhodhi redunhu rese, njodzi yezvinetso zvine chekuita neEMI inogona kuderedzwa zvakanyanya.

Chimwe chinhu chekufunga nezvekuiswa uye kufambiswa kwezviratidzo zvinomhanya-mhanya.Zviratidzo zvine kukurumidza kusimuka uye nguva dzekudonha zvinonyanya kubatwa neEMI radiation uye zvinogona kukanganisa zvimwe zvikamu pabhodhi.Nekunyatso kupatsanura masaini ekumhanya-mhanya kubva kuzvinhu zvinonzwisa tsitsi zvakaita seanalog maseketi, njodzi yekukanganisa inogona kuderedzwa.Uye zvakare, kushandiswa kweanosiyanisa kusaina nzira kunogona kuwedzera kuvandudza EMI / EMC mashandiro nekuti ivo vanopa iri nani ruzha kusadzivirirwa kana ichienzaniswa nemasaini-anopera masaini.

Kusarudzwa kwechikamu kwakakoshawo kune EMI/EMC kuteedzera kune rigid-flex redunhu mabhodhi.Kusarudza zvikamu zvine akakodzera EMI/EMC hunhu, senge yakaderera EMI emissions uye yakanaka kusadzivirirwa kune yekukanganisa kwekunze, inogona kuvandudza zvakanyanya kuita kwese kwebhodhi.Zvikamu zvine akavakirwa-mukati EMI/EMC hunyanzvi, senge akasanganiswa mafirita kana kudzivirira, anogona kurerutsa maitiro ekugadzira uye kuve nechokwadi chekutevedzera mitemo.

Insulation yakakodzera uye kudzivirira zvakare zvakakosha kufunga.Mune akaomesesa-flex edunhu mabhodhi, iwo anochinjika zvikamu anotapukirwa nemechini kusagadzikana uye anonyanya kubatwa neEMI radiation.Kuve nechokwadi chekuti zvikamu zvinochinjika zvadzivirirwa zvakaringana uye kuchengetedzwa zvinogona kubatsira kudzivirira nyaya dzine chekuita neEMI.Pamusoro pezvo, kusungirira kwakaringana pakati pematanho ekuitisa uye masaini kunoderedza njodzi yekuyambuka uye kukanganiswa kwechiratidzo.

Vagadziri vanofanirwawo kutarisisa kune yakazara dhizaini uye stackup yeakaomesesa-flex mabhodhi.Nekunyatsoronga iwo akasiyana akaturikidzana uye zvikamu, EMI/EMC kuita kunogona kudzorwa zvirinani.Masignal layers anofanirwa kuiswa pakati pevhu kana masimba emagetsi kuderedza kubatanidza kwechiratidzo uye kuderedza njodzi yekukanganisa.Pamusoro pezvo, kushandisa EMI/EMC dhizaini dhizaini nemitemo inogona kubatsira kuona kuti dhizaini yako inosangana nezvinodiwa zvekuteedzera.

Kuedzwa uye kusimbiswa kunoita basa rakakosha mukuwana EMI/EMC kuteedzera kwemabhodhi akaomesesa edunhu.Mushure mekutanga dhizaini yapedzwa, kuyedzwa kwakakwana kunofanirwa kuitwa kuratidza mashandiro ebhodhi.EMI emission bvunzo inoyera huwandu hwemagetsi emagetsi emagetsi anoburitswa nedhiketi redunhu, nepo EMC bvunzo inoongorora kusadzivirirwa kwayo nekukanganiswa kwekunze.Iyi bvunzo inogona kubatsira kuona chero nyaya uye kubvumidza shanduko dzinodiwa kuti dziitwe kuti zvitevedzere.

Muchidimbu, kuve nechokwadi chekuti EMI/EMC inoteera kune yakaomesesa-flex edunhu mabhodhi inoda kunyatsotariswa kwezvinhu zvakasiyana.Kubva pakugadzika kwakakodzera uye kusarudzwa kwechikamu kuenda kuchiratidzo chekufambisa uye kuyedzwa, nhanho imwe neimwe inoita basa rakakosha mukuwana bhodhi rinosangana nemirairo.Nekugadzirisa izvi zvinotariswa uye nekutevera akanakisa maitiro, vagadziri vanogona kugadzira yakasimba uye yakavimbika rigid-flex edunhu mabhodhi anoita zvakanaka munzvimbo dzakanyanya-kushushikana uku achisangana neEMI/EMC zvinodiwa.
