Ko akaomesesa-flex edunhu mabhodhi anogona kushandiswa muRF application?

Munyika iri kukurumidza kushanduka yemagetsi, hunyanzvi uye kuita zvakasiyana ndizvo zvakakosha kuti urambe uri pamberi pemakwikwi. Radio frequency (RF) zvikumbiro inzvimbo inosangana nekukura kukuru. Kubva pane isina waya yekutaurirana masisitimu kuenda kune satellite tekinoroji uye radar masisitimu, maRF maapplication anoita basa rakakosha. Kusangana nezvinodiwa zvezvikumbiro izvi, mainjiniya nevagadziri vanogara vachitsvaga mhinduro nyowani.Imwe mhinduro yakakurumbira ndeye kushandisa rigid flex circuit board. Asi akaomesesa-flex edunhu mabhodhi anogona kushandiswa muRF application? Mune ino blog, tichaongorora nyaya iyi zvakadzama.

Rigid-flex circuit boards isanganiswa yemapuranga akaoma uye anoshanduka-shanduka. Vanosanganisa akanakisa emhando mbiri, zvichiita kuti ive yakanaka kune yakaoma yemagetsi magadzirirwo.Zvikamu zvakaomarara zvinopa kugadzikana uye kutsigirwa kwechimiro, nepo zvikamu zvinochinjika zvichibvumira kupeta nekupeta, zvichivabvumira kupinda munzvimbo dzakasimba. Uku kusanganiswa kwakasarudzika kunoita kuti rigid-flex boards ikwane kune dzakasiyana siyana dzekushandisa, kusanganisira redhiyo frequency.

RF zvikumbiro zvinoda kufambisa uye kwakaringana kutapurirana kweakakwira-frequency masaini. Chero kukanganisa kana kurasikirwa kwechiratidzo chemhando kuchakanganisa mashandiro ehurongwa.Rigid-flex circuit boards inopa yakanakisa chiratidzo kutendeseka nekuda kwekuderera kwavo kurasikirwa maitiro. Iyo dielectric zvinhu zvinoshandiswa mukuvaka kwayo zvine yakaderera dissipation chinhu, kuve nechokwadi kushoma chiratidzo attenuation. Izvi zvakakosha kune maRF application apo simba rechiratidzo rinoita basa rakakosha.

Imwe mukana weakaomesesa-flex edunhu mabhodhi eRF maapplication kugona kudzikisa electromagnetic interference (EMI) uye radio frequency interference (RFI).Zvikamu zvinoshanduka zvemapuranga aya zvinoshanda senhovo, kudzivirira kupindira kwekunze kubva pakukanganisa chiratidzo. Ichi chidziviriro chivakwa chinonyanya kubatsira kune RF masisitimu anoda kunzwisiswa kwakanyanya uye nemazvo.

Pamusoro pezvo, iyo yakasarudzika dhizaini yeakaomesesa-flex edunhu mabhodhi anobvumira kunyatso kudzora kwemazinga e impedance. Impedance kuenzanisa kwakakosha muRF zvikumbiro kuti ive nechokwadi chekufambisa kwemagetsi uye kudzivirira zviratidzo zvechiratidzo.Rigid-flex mabhodhi anopa mainjiniya shanduko yekugadzira akawanda impedance mazinga pabhodhi rimwe chete, achibvisa kudiwa kwezvimwe zvikamu kana maitiro akaomarara egungano.

Rigid-flex wedunhu mabhodhi anopa akati wandei mabhenefiti maererano nekugadzira kufunga. Iyo compact dhizaini inochengetedza nzvimbo uye inoderedza kudiwa kwezvibatanidza uye tambo, kurerutsa yakazara system dhizaini.Uyezve, kubvisa zvibatanidza kunoderedza njodzi yekurasikirwa kwechiratidzo uye kunowedzera kuvimbika. Izvi zvinonyanya kukosha kune RF zvikumbiro zvinoda kuenderana uye kusinga vhiringike kufambisa kwemasaini.

Izvo zvakakosha kuti ticherechedze kuti kubudirira kwekuita kweakaomesesa-flex edunhu mabhodhi muRF maapplication anoda kungwarira dhizaini uye magadzirirwo ekufunga.Yakakodzera stackup dhizaini, kuronda nzira, uye chiratidzo chepasi kwakakosha kukwenenzvera kuita. Kudyidzana pakati pemainjiniya, vagadziri, uye vagadziri kwakakosha kuti ive nechokwadi chekuti dhizaini yakasangana uye kuti chigadzirwa chekupedzisira chinosangana nezvinodiwa zveRF.

Muchidimbu

Rigid-flex wedunhu mabhodhi anogona zvechokwadi kushandiswa muRF maapplication. Musanganiswa wavo wakasarudzika wekuoma uye kuchinjika, pamwe chete nekushomeka-kurasikirwa zvivakwa uye EMI/RFI kudzivirira, vanovaita sarudzo inoshanda. Nekugona kwavo kunyatso kudzora mazinga e impedance uye mabhenefiti avo ekugadzira, akaomesesa-flex mabhodhi anopa mhinduro inovimbisa yeRF masisitimu.

Nekudaro, zvakakosha kusimbisa kukosha kwekugadzira kwakaringana uye kubatana pakati pevose vanobatanidzwa. Kutarisa kune zvakadzama panguva yekugadzira uye kugadzira kwakakosha kuti uwane yakakwana RF kuita. Nemaitiro akakodzera, akaomesesa-flex edunhu mabhodhi anogona kuunza kuvimbika, kushanda nesimba uye kuita kunodiwa kune akasiyana siyana eRF maapplication, zvichibatsira kune inogara ichiwedzera isina waya kutaurirana uye tekinoroji mamiriro.
