Ma board a Rigid-Flex Amagwira Ntchito | Kupanga Zosasinthika za PCB

Mu positi iyi yabulogu, tiwona kuti rigid-flex board ndi chiyani komanso momwe amagwirira ntchito.

Ponena za dziko la zipangizo zamagetsi, munthu sanganyalanyaze kufunika kwa matabwa osindikizira (PCBs). Zigawo zing'onozing'ono koma zofunika kwambiri ndizo msana wa zipangizo zamakono zamakono. Amapereka maulumikizidwe ofunikira pazigawo zosiyanasiyana kuti athe kugwirira ntchito limodzi mosasunthika. Ukadaulo wa PCB wasintha kwambiri pazaka zambiri, zomwe zidapangitsa kuti pakhale mitundu yosiyanasiyana yama board ozungulira, kuphatikiza ma board olimba.

Choyamba, tiyeni timvetsetse mfundo zoyambira za rigid-flex board.Monga momwe dzinalo likusonyezera, matabwa okhwima-osinthika amaphatikiza zinthu zolimba komanso zosinthika pa bolodi imodzi yozungulira. Imapereka zabwino kwambiri zamitundu yonse, ndikupangitsa kuti ikhale yabwino pamapulogalamu ambiri.

Ma board a Rigid-flex amakhala ndi magawo angapo a magawo osinthika omwe amalumikizidwa ndi magawo olimba.Magawo osinthikawa amapangidwa ndi zinthu za polyimide, zomwe zimawalola kupindika ndikupotoza osasweka. Mbali yolimba, kumbali ina, nthawi zambiri imapangidwa ndi fiberglass-reinforced epoxy material, yomwe imapereka bata ndi chithandizo chofunikira.

Kuphatikiza kwa magawo okhwima komanso osinthika kumapereka maubwino ambiri.Choyamba, zimapangitsa kuti pakhale mawonekedwe ophatikizika kwambiri chifukwa magawo osinthika amatha kupindika kapena kupindika kuti agwirizane ndi malo olimba. Izi zimapangitsa ma board okhazikika kukhala othandiza makamaka pamapulogalamu omwe malo ndi ochepa, monga zida zam'manja kapena ukadaulo wovala.

Kuphatikiza apo, kugwiritsa ntchito magawo osinthika kungapangitse kudalirika.Ma board achikhalidwe okhazikika amatha kuvutika ndi zovuta monga kutopa kwa solder kapena kupsinjika kwamakina chifukwa cha kusinthasintha kwa kutentha kapena kugwedezeka. Kusinthasintha kwa gawo lapansi mu bolodi lokhazikika-lokhazikika kumathandiza kuyamwa zovuta izi, potero kuchepetsa chiopsezo cholephera.

Tsopano popeza tamvetsetsa kapangidwe kake ndi maubwino a ma rigid-flex board, tiyeni tiwone mwatsatanetsatane momwe amagwirira ntchito.Makanema olimba amapangidwa pogwiritsa ntchito pulogalamu yothandizidwa ndi makompyuta (CAD). Mainjiniya amapanga mawonekedwe owoneka bwino a board board, kufotokozera masanjidwe a zigawo, ma trace, ndi ma vias.

Mapangidwewo akamaliza, amadutsa m'njira zingapo zopangira.Gawo loyamba likuphatikizapo kupanga gawo lolimba la bolodi lozungulira. Izi zimachitika pomanga pamodzi zigawo za fiberglass-reinforced epoxy material, zomwe zimakhazikika kuti zipange madera ofunikira.

Kenako, gawo lapansi losinthika limapangidwa.Izi zimatheka poyika mkuwa wochepa thupi pa chidutswa cha polyimide ndikumangirira kuti apange mayendedwe ofunikira. Zigawo zingapo za magawo osinthikawa amapangidwa pamodzi kuti apange gawo losinthika la bolodi.

Zomatira zimagwiritsidwa ntchito kulumikiza mbali zolimba komanso zosinthika pamodzi.Zomatirazi zimasankhidwa mosamala kuti zitsimikizire kuti pali mgwirizano wamphamvu komanso wodalirika pakati pa zigawo ziwirizi.

Bolodi yolimba-flex itasonkhanitsidwa, imadutsa njira zosiyanasiyana zoyesera kuti zitsimikizire kuti zimagwira ntchito komanso zodalirika.Mayeserowa akuphatikizapo kufufuza kupitiriza, kutsimikizira kukhulupirika kwa chizindikiro, ndi kuyesa mphamvu ya bolodi yolimbana ndi chilengedwe.

Potsirizira pake, bolodi lomalizidwa lokhazikika-lokonzeka kuphatikizidwa mu chipangizo chamagetsi chomwe chinapangidwira.Imalumikizidwa kuzinthu zina pogwiritsa ntchito soldering kapena njira zina zolumikizirana, ndipo msonkhano wonsewo umayesedwanso kuti zitsimikizire kugwira ntchito moyenera.

Mwachidule, matabwa olimba-flex ndi njira yatsopano yomwe imaphatikiza ubwino wa matabwa ozungulira okhwima komanso osinthasintha.Amapereka mapangidwe ophatikizika, kudalirika kowonjezereka, komanso kuthekera kopirira madera ovuta. Kupanga kumaphatikizapo kusakanikirana kosamalitsa kwa zinthu zolimba komanso zosinthika, zomwe zimapangitsa kuti pakhale zida zamagetsi zodalirika komanso zodalirika. Pamene ukadaulo ukupitilirabe patsogolo, titha kuyembekezera kuti kugwiritsa ntchito ma board okhazikika kufalikira m'mafakitale osiyanasiyana.
