M'dziko lamagetsi lomwe likukula mwachangu, kufunikira kwa ma PCB a Rigid-Flex ochita bwino kwambiri kukukulirakulira. Ma board ozungulira otsogolawa amaphatikiza zabwino za ma PCB okhazikika komanso osinthika, zomwe zimapangitsa kuti pakhale mapangidwe apamwamba omwe angagwirizane ndi malo ophatikizika ndikusunga kudalirika komanso magwiridwe antchito. Monga wopanga mapulogalamu ambiri a PCB, Capel Technology imamvetsetsa zovuta zomwe zimapangidwira kupanga ndi kupanga matabwa ovutawa. Nkhaniyi ikuyang'ana njira zokometsera zamapangidwe ozungulira mu multilayer Rigid-Flex PCBs, kuwonetsetsa kuti akukwaniritsa zofunikira zamagetsi amakono.
1. Kukhazikitsa koyenera kwa Chigawo Chosindikizidwa Mizere
Chimodzi mwazinthu zofunika kwambiri pakupanga ma multilayer Rigid-Flex PCB ndi kusiyana pakati pa mizere yosindikizidwa ndi zigawo zake. Kutalikirana kumeneku ndikofunikira pakuwonetsetsa kuti magetsi amatsekeredwa komanso kutsata njira zopangira. Pamene mabwalo othamanga kwambiri komanso otsika kwambiri amakhala pa bolodi lomwelo, ndikofunikira kusunga mtunda wokwanira wachitetezo kuti mupewe kusokoneza magetsi ndi kulephera komwe kungachitike. Okonza amayenera kuwunika mosamala kuchuluka kwa magetsi ndi kutsekeka komwe kumafunikira kuti adziwe malo abwino kwambiri, kuwonetsetsa kuti bolodi imagwira ntchito bwino komanso moyenera.
2. Kusankha Mtundu wa Mzere
Zokongola ndi magwiridwe antchito a PCB zimakhudzidwa kwambiri ndi kusankha kwa mizere. Kwa ma multilayer Rigid-Flex PCBs, mawonekedwe apakona a mawaya ndi mtundu wa mzere wonse ayenera kusankhidwa mosamala. Zosankha zodziwika bwino zimaphatikizapo ma angle a 45-degree, 90-degree angles, ndi arcs. Acute angles nthawi zambiri amapewedwa chifukwa cha kuthekera kwawo kuti apange mfundo zopanikiza zomwe zingayambitse kulephera pakupindika kapena kupindika. M'malo mwake, opanga azikonda kusintha kwa ma arc kapena ma degree 45, zomwe sizimangowonjezera kupangidwa kwa PCB komanso zimathandizira kukopa kwake.
3. Kutsimikiza kwa Mzere Wosindikizidwa M'lifupi
Kukula kwa mizere yosindikizidwa pa multilayer Rigid-Flex PCB ndi chinthu china chofunikira chomwe chimakhudza magwiridwe antchito. Kutalika kwa mzere kuyenera kutsimikiziridwa kutengera milingo yomwe oyendetsa angatenge komanso kuthekera kwawo kukana kusokoneza. Monga lamulo, kukula kwakukulu kwamakono, mzerewo uyenera kukhala waukulu. Izi ndizofunikira kwambiri pamagetsi ndi mizere yapansi, yomwe iyenera kukhala yokhuthala momwe mungathere kuti ma waveform akhazikike ndikuchepetsa kutsika kwamagetsi. Ndi kukhathamiritsa mzere m'lifupi, okonza akhoza kupititsa patsogolo ntchito zonse ndi kudalirika kwa PCB.
4. Anti-Interference ndi Electromagnetic Shielding
M'malo amakono amagetsi apamwamba kwambiri, kusokoneza kumatha kukhudza kwambiri magwiridwe antchito a PCB. Chifukwa chake, njira zothana ndi kusokoneza komanso chitetezo chamagetsi ndizofunikira pakupanga ma multilayer Rigid-Flex PCBs. Mawonekedwe a dera omwe amaganiziridwa bwino, ophatikizidwa ndi njira zoyenera zoyambira pansi, amatha kuchepetsa kwambiri zosokoneza ndikuwongolera kuyanjana kwamagetsi. Pa mizere yofunikira kwambiri, monga ma siginecha a wotchi, ndikofunikira kugwiritsa ntchito milondo yotakata ndikuyika mawaya omata otsekera ndikuzipatula. Njirayi sikuti imangoteteza zizindikiro zowonongeka komanso imapangitsanso kukhulupirika kwa dera lonse.
5. Mapangidwe a Rigid-Flex Transition Zone
Malo osinthira pakati pa magawo olimba komanso osinthika a Rigid-Flex PCB ndi gawo lofunikira lomwe limafunikira kupangidwa mosamala. Mizere yomwe ili m'derali iyenera kusuntha bwino, ndi njira yake yokhotakhota. Kulingalira kwapangidwe kumeneku kumathandiza kuchepetsa kupsinjika kwa ma conductor panthawi yosinthasintha, kuchepetsa chiopsezo cholephera. Kuphatikiza apo, makulidwe a ma conductor akuyenera kukulitsidwa kudera lonse lopindika kuti awonetsetse kuti akuyenda bwino. Ndikofunikiranso kupewa kupyola mabowo m'malo omwe amapindika, chifukwa amatha kupanga zofooka. Kuti apititse patsogolo kudalirika, opanga amatha kuwonjezera mawaya amkuwa oteteza kumbali zonse za mzere, kupereka chithandizo chowonjezera ndi chitetezo.
