Kusiyana-siyana kweRigid-Flex Mabhodhi muKugara Yepamusoro-Speed ​​Signs

suma:

Mune ino blog, isu tichaongorora kuchinjika kweakaomesesa-flex mabhodhi uye kugona kwavo kubata masaini ekumhanya.

Munyika yanhasi ine tekinoroji yepamusoro, umo midziyo yemagetsi iri kuita diki, kureruka, uye kuomarara, kudiwa kwemabhodhi edunhu anochinjika uye anomhanya-mhanya (PCBs) kuri kuramba kuchiwedzera. Rigid-flex mabhodhi akabuda semhinduro inoshanda inosanganisa zvakanakira akaomesesa uye anochinjika maPCB, achivaita akanakira kugarisa masaini ekumhanya.

Chikamu 1: Kunzwisisa Rigid-Flex Mabhodhi

Rigid-flex imhando yakasanganiswa yePCB inosanganisa zvidimbu zvezvakaomarara uye zvinochinjika zvinhu. Aya mabhodhi anosanganisira maseketi anochinjika akabatana nezvikamu zvakaomarara, achipa zvese kugadzikana kwemichina uye kuchinjika. Iko kusanganiswa kwezvikamu zvakaoma uye zvinoshanduka zvinobvumira bhodhi kukotama kana kupeta sezvinodiwa pasina kukanganisa kushanda kwayo.

Chikamu 2: High Speed ​​​​Signal Transmission

High-speed zviratidzo zviri kukurumidza kuchinja zviratidzo zvemagetsi zvinodarika imwe frequency threshold. Aya masaini anoda kutariswa kwakakosha panguva yePCB dhizaini uye dhizaini kudzivirira chiratidzo chekuvimbika nyaya senge crosstalk, impedance mismatch, uye chiratidzo chinokanganisa. Rigid-flex boards ane zvakasarudzika mabhenefiti mukugadzirisa-kumhanya masaini nekuda kwekuchinjika kwavo uye ipfupi chiratidzo chekufambisa chinhambwe.

Chikamu 3: Yakaomeswa-inochinjika dhizaini kufunga kune yakakwirira-kumhanya masaini

3.1 Inodzorwa impedance:
Kuchengeta inodzorwa impedance kwakakosha kune yakakwira-kumhanya chiratidzo kutendeseka. Rigid-flex mabhodhi anobvumira zvirinani impedance kudzora nekuti zvikamu zvinochinjika zvinogona kugadzirwa neiyo chaiyo trace geometries uye hupamhi. Izvi zvinobvumira kushoma routing shanduko yechiratidzo chechiratidzo, kuve nechokwadi chekusagadzikana impedance mubhodhi rose.

3.2 Signal routing uye layer stacking:
Yakafanira chiratidzo chekufambisa uye layer stacking yakakosha kudzikisa chiratidzo checrosstalk uye kuwana yakakwana kuita. Rigid-flex boards inobvumira kuiswa kunochinjika kweyepamusoro-speed sign traces, nekudaro kupfupisa kutapurirana madaro uye kuderedza kusingadiwe chiratidzo chekudyidzana. Pamusoro pezvo, kugona kurongedza akawanda akaturikidzana mukati me compact fomu chinhu kunogonesa kupatsanurwa kwakanaka kwesimba nendege dzepasi, zvichiwedzera kusimbisa kutendeseka kwechiratidzo.

3.3 EMI uye crosstalk kuderedza:
Electromagnetic interference (EMI) uye crosstalk matambudziko akajairika kana uchibata masaini ekumhanya. Kubatsira kweakaomesesa-flex mabhodhi ndiko kusanganiswa kwekudzivirira uye kwakaringana pasi ndege gadziriro, iyo inoderedza njodzi yeEMI uye crosstalk. Izvi zvinovimbisa kuti chiratidzo chinoramba chakagadzikana uye chisina kukanganiswa, kuvandudza maitiro ehurongwa hwese.

Chikamu 4: Zvakanakira uye mashandisirwo eakakwira-kumhanya chiratidzo rigid-flex mabhodhi

4.1 dhizaini inochengetedza nzvimbo:
Rigid-flex mapaneru ane mabhenefiti akakosha mumashandisirwo apo nzvimbo yakaganhurirwa. Kugona kwavo kukotama uye kuchinjika kune iripo nzvimbo inobvumira kushandiswa kwakaringana kwenzvimbo, ichiita kuti ive yakanakira compact midziyo yemagetsi.

4.2 Kuvimbika uye Kusimba:
Rigid-flex boards inopa kuvimbika kwakakura kupfuura echinyakare akaomesesa maPCB nekuda kwekuderedzwa kwekubatanidza kuverenga uye zvinogona kukundikana mapoinzi. Pamusoro pezvo, kusavapo kwezvibatanidza uye tambo dzeribhoni kunoderedza njodzi yekushatiswa kwechiratidzo uye kunovimbisa kusimba kwenguva refu.

4.3 Kushandisa:
Rigid-flex boards anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira aerospace, zvigadzirwa zvekurapa, zvemagetsi zvevatengi uye mota. Ndiyo yekutanga sarudzo yezvikumbiro uko ukuru, uremu uye kuvimbika kwakakosha uye uko kumhanyisa-kumhanya chiratidzo chekufambisa kunodiwa.

Mukupedzisa:

Sezvo kudiwa kweiyo-yepamusoro-yekumhanya chiratidzo chekufambisa ichiramba ichikura, rigid-flex mabhodhi ave mhinduro inoshanda. Musanganiswa wavo wakasarudzika wekuchinjika, dhizaini inochengetedza nzvimbo uye chiratidzo chekuvimbika maficha anoita kuti ive yakanakira kugarisa masaini ekumhanya. Nekusanganisa inodzorwa impedance, inonyatso fambisa chiratidzo uye yakakodzera EMI/crosstalk kuderedza matekiniki, rigid-flex mabhodhi anovimbisa kuita kwakavimbika uye kwakaringana mumhando dzakasiyana dzekushandisa.
