Kusinthasintha kwa Ma board a Rigid-Flex Pokhala ndi Zizindikiro Zothamanga Kwambiri

Tsegulani:

Mu blog iyi, tiwona kusinthasintha kwa ma board okhazikika komanso kuthekera kwawo kunyamula ma siginecha othamanga kwambiri.

M'dziko lamakono lamakono laukadaulo, momwe zida zamagetsi zikukhala zazing'ono, zopepuka, komanso zovuta, kufunikira kwa ma board osinthika komanso othamanga kwambiri (PCBs) kukukulirakulira. Ma board olimba osinthika atuluka ngati njira yothandiza yomwe imaphatikiza zabwino za PCB zolimba komanso zosinthika, zomwe zimawapangitsa kukhala abwino kuti azitha kulandira ma siginecha othamanga kwambiri.

Gawo 1: Kumvetsetsa Ma board a Rigid-Flex

Rigid-flex ndi mtundu wosakanizidwa wa PCB womwe umaphatikiza zigawo zolimba komanso zosinthika. Ma board awa amakhala ndi mabwalo osinthika olumikizidwa ndi magawo olimba, omwe amapereka kukhazikika kwamakina komanso kusinthasintha. Kuphatikizika kwa magawo okhwima komanso osinthika kumapangitsa kuti bolodi ipindike kapena kupindika ngati pakufunika popanda kusokoneza magwiridwe ake.

Gawo 2: Kutumiza kwa Signal High Speed

Zizindikiro zothamanga kwambiri zikusintha mofulumira zizindikiro zamagetsi zomwe zimadutsa malire afupipafupi. Zizindikirozi zimafunika kuganiziridwa mwapadera panthawi ya mapangidwe a PCB ndi masanjidwe kuti apewe kukhulupirika kwa ma sign monga crosstalk, impedance mismatch, ndi kupotoza kwa ma sign. Ma board a Rigid-flex ali ndi mwayi wapadera pokonza ma siginecha othamanga kwambiri chifukwa cha kusinthasintha kwawo komanso mtunda waufupi wotumizira ma siginecha.

Gawo 3: Malingaliro okhazikika osinthika pamasinthidwe othamanga kwambiri

3.1 Impedance yoyendetsedwa:
Kusunga impedance yoyendetsedwa ndikofunikira kuti pakhale kukhulupirika kwamphamvu kwambiri. Ma board a Rigid-flex amalola kuwongolera bwino kwa impedance chifukwa magawo osinthika amatha kupangidwa ndi ma geometries ndi m'lifupi mwake. Izi zimalola kusintha kwakung'ono kwa njira zotsatsira ma siginecha, kuwonetsetsa kusasinthika kwa gulu lonse.

3.2 Mayendedwe a ma Signal ndi masanjidwe osanjikiza:
Mayendedwe oyenera a ma sign ndi masanjidwe osanjikiza ndizofunikira kuti muchepetse kuphatikizika kwa ma signal ndikuchita bwino. Ma board a Rigid-flex amalola kuyika kosinthika kwa ma trace othamanga kwambiri, potero amafupikitsa mtunda wotumizira ndikuchepetsa kuyanjana kwa ma siginecha kosafunika. Kuphatikiza apo, kutha kuyika zigawo zingapo mkati mwa compact form factor kumathandizira kulekanitsa bwino kwa mphamvu ndi ndege zapansi, kupititsa patsogolo kukhulupirika kwazizindikiro.

3.3 EMI ndi kuchepetsa kufalikira kwa mawu:
Electromagnetic interference (EMI) ndi crosstalk ndizovuta zomwe zimachitika pogwira ma siginecha othamanga kwambiri. Ubwino wa matabwa okhwima-osinthika ndikuphatikiza zotchingira ndi masinthidwe oyenera a ndege, zomwe zimachepetsa chiopsezo cha EMI ndi crosstalk. Izi zimatsimikizira kuti chizindikirocho chimakhala chokhazikika komanso chopanda kusokoneza, kupititsa patsogolo machitidwe onse.

Gawo 4: Ubwino ndi kugwiritsa ntchito ma board othamanga kwambiri a siginecha

4.1 Mapangidwe opulumutsa malo:
Mapanelo olimba-flex ali ndi maubwino ofunikira pamapulogalamu omwe malo ndi ochepa. Kukhoza kwawo kupindika ndikusintha malo omwe alipo amalola kugwiritsa ntchito bwino malo, kuwapangitsa kukhala abwino kwa zida zamagetsi zamagetsi.

4.2 Kudalirika ndi Kukhazikika:
Ma board olimba-flex amapereka kudalirika kwambiri kuposa ma PCB okhazikika chifukwa cha kuchepa kwa kuwerengera komanso kulephera komwe kungatheke. Kuphatikiza apo, kusakhalapo kwa zolumikizira ndi zingwe za riboni kumachepetsa chiopsezo cha kuwonongeka kwa ma sign ndikuwonetsetsa kukhazikika kwanthawi yayitali.

4.3 Ntchito:
Ma board a Rigid-flex amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza zakuthambo, zida zamankhwala, zamagetsi ogula ndi magalimoto. Ndiwo kusankha koyambirira kwa mapulogalamu omwe kukula, kulemera ndi kudalirika ndizofunikira komanso kumene kutumizira zizindikiro zothamanga kwambiri kumafunika.

Pomaliza:

Pamene kufunikira kwa kufalitsa ma siginecha othamanga kwambiri kukupitilira kukula, ma board olimba-flex akhala yankho losunthika. Kuphatikizika kwawo kwapadera kwa kusinthasintha, mapangidwe opulumutsa malo ndi mawonekedwe a kukhulupirika kwa chizindikiro kumawapangitsa kukhala abwino kuti agwirizane ndi zizindikiro zothamanga kwambiri. Mwa kuphatikiza kutsekereza koyendetsedwa, kuwongolera ma siginecha koyenera komanso njira zoyenera zochepetsera za EMI/crosstalk, ma board olimba-flex amawonetsetsa kuti magwiridwe antchito odalirika komanso oyenera pamagwiritsidwe osiyanasiyana.
