Chifukwa cha mawonekedwe ake ovuta komanso mawonekedwe apadera,kupanga matabwa olimba-flex kumafuna njira zapadera zopangira. Mu positi iyi yabulogu, tiwona njira zosiyanasiyana zomwe zimakhudzidwa popanga matabwa apamwamba a PCB osinthika ndikuwonetsa malingaliro omwe akuyenera kuganiziridwa.
Ma board osindikizira (PCBs) ndi msana wamagetsi amakono. Ndiwo maziko a zida zamagetsi zolumikizidwa, zomwe zimawapanga kukhala gawo lofunikira pazida zambiri zomwe timagwiritsa ntchito tsiku lililonse. Pamene luso laukadaulo likupita patsogolo, pakufunikanso mayankho osinthika komanso ophatikizana. Izi zapangitsa kuti pakhale ma PCB okhwima, omwe amapereka kuphatikiza kwapadera komanso kusinthasintha pa bolodi limodzi.
Pangani bolodi lokhazikika lokhazikika
Gawo loyamba komanso lofunika kwambiri pakupanga makina okhwima ndi kupanga. Kupanga bolodi lolimba-flex kumafuna kulingalira mosamalitsa masanjidwe onse a bolodi lozungulira ndi kakhazikitsidwe kagawo. Madera a Flex, bend radii ndi malo opindika amayenera kufotokozedwa panthawi ya mapangidwe kuti awonetsetse kuti bolodi yomalizidwa ikugwira ntchito moyenera.
Zida zomwe zimagwiritsidwa ntchito mu ma PCB okhwima ziyenera kusankhidwa mosamala kuti zikwaniritse zofunikira za pulogalamuyi. Kuphatikizika kwa magawo okhwima komanso osinthika kumafuna kuti zida zosankhidwa zikhale ndi kuphatikiza kwapadera komanso kukhazikika. Nthawi zambiri magawo osinthika monga polyimide ndi FR4 woonda amagwiritsidwa ntchito, komanso zinthu zolimba monga FR4 kapena zitsulo.
Layer Stacking ndi Kukonzekera gawo lapansi kuti likhale lolimba flex pcb kupanga
Mapangidwewo akamaliza, njira yosungiramo zosanjikiza imayamba. Ma board osindikizira olimba osinthika amakhala ndi zigawo zingapo zolimba komanso zosinthika zomwe zimalumikizidwa palimodzi pogwiritsa ntchito zomatira zapadera. Kulumikizana kumeneku kumatsimikizira kuti zigawozo zimakhalabe ngakhale pansi pa zovuta monga kugwedezeka, kupindika ndi kusintha kwa kutentha.
Chotsatira chotsatira pakupanga ndikukonzekera gawo lapansi. Izi zikuphatikizapo kuyeretsa ndi kuyeretsa pamwamba kuti zitsimikizire kuti zimamatira bwino. Njira yoyeretsera imachotsa zonyansa zilizonse zomwe zingalepheretse kugwirizanitsa, pamene chithandizo chapamwamba chimapangitsa kumamatira pakati pa zigawo zosiyanasiyana. Njira monga mankhwala a plasma kapena etching yamankhwala nthawi zambiri amagwiritsidwa ntchito kuti akwaniritse zomwe akufuna.
Copper patterning ndi mkati wosanjikiza mapangidwe kwa okhwima flexible dera matabwa facbrication
Pambuyo pokonzekera gawo lapansi, pitirizani kutsata ndondomeko yamkuwa. Izi zimaphatikizapo kuyika kagawo kakang'ono ka mkuwa pagawo laling'ono kenako ndikujambula chithunzithunzi kuti mupange mawonekedwe adera omwe mukufuna. Mosiyana ndi ma PCB achikhalidwe, ma PCB okhwima amafunikira kuganizira mozama za gawo losinthika panthawi yopanga mapangidwe. Chisamaliro chapadera chiyenera kuchitidwa kuti tipewe kupanikizika kosafunikira kapena kuwonongeka kwa magawo osinthika a bolodi la dera.
Akamaliza kupanga mapangidwe amkuwa, mapangidwe amkati amkati amayamba. Mu sitepe iyi, zigawo zolimba ndi zosinthika zimagwirizanitsidwa ndipo kugwirizana pakati pawo kumakhazikitsidwa. Izi nthawi zambiri zimatheka pogwiritsa ntchito vias, zomwe zimapereka kulumikizana kwamagetsi pakati pa zigawo zosiyanasiyana. Vias iyenera kupangidwa mosamala kuti igwirizane ndi kusinthasintha kwa bolodi, kuonetsetsa kuti sizikusokoneza ntchito yonse.
Lamination ndi kunja wosanjikiza mapangidwe okhwima-flex pcb kupanga
Pamene wosanjikiza wamkati wapangidwa, ndondomeko ya lamination imayamba. Izi zimaphatikizapo kuunjika zigawozo ndi kuziyika pa kutentha ndi kupanikizika. Kutentha ndi kupanikizika kumayambitsa zomatira ndikulimbikitsa kugwirizana kwa zigawozo, kupanga dongosolo lolimba komanso lolimba.
Pambuyo lamination, akunja wosanjikiza mapangidwe ndondomeko akuyamba. Izi zimaphatikizapo kuyika mkuwa wochepa thupi kunja kwa bolodi la dera, ndikutsatiridwa ndi ndondomeko ya photolithography kuti apange dongosolo lomaliza la dera. Mapangidwe a kunja wosanjikiza kumafuna kulondola ndi kulondola kuti zitsimikizidwe zolondola za dongosolo la dera ndi wosanjikiza wamkati.
Kubowola, plating ndi pamwamba mankhwala kwa okhwima kusintha pcb matabwa matabwa
Chotsatira chotsatira pakupanga ndikubowola. Izi zikuphatikizapo kubowola mabowo mu PCB kulola kuti zigawo zilowetsedwe komanso kuti magetsi apangidwe. Kubowola kosasunthika kwa PCB kumafuna zida zapadera zomwe zimatha kutengera makulidwe osiyanasiyana ndi ma board osinthika ozungulira.
Pambuyo pobowola, electroplating ikuchitika kumapangitsanso madutsidwe wa PCB. Izi zimaphatikizapo kuyika chitsulo chopyapyala (kawirikawiri mkuwa) pamakoma a dzenje lobowola. Mabowo okulungidwa amapereka njira yodalirika yokhazikitsira kugwirizana kwa magetsi pakati pa zigawo zosiyanasiyana.
Pomaliza, kumaliza pamwamba kumachitika. Izi zimaphatikizapo kuyika zokutira zoteteza pamalo amkuwa omwe ali poyera kuti apewe dzimbiri, kupangitsa kuti zisawonongeke, ndikuwongolera magwiridwe antchito onse a bolodi. Kutengera ndi zofunikira pakugwiritsa ntchito, chithandizo chamankhwala chosiyanasiyana chilipo, monga HASL, ENIG kapena OSP.
Kuwongolera kwaubwino ndi kuyezetsa pakupanga makina osinthika osindikizidwa osindikizidwa
Pa nthawi yonse yopangira zinthu, njira zoyendetsera khalidwe zimayendetsedwa kuti zitsimikizidwe kuti zikhale zodalirika komanso zogwira ntchito. Gwiritsani ntchito njira zapamwamba zoyesera monga automated optical inspection (AOI), kuyendera ma X-ray ndi kuyezetsa magetsi kuti muzindikire zolakwika kapena zovuta zilizonse mu board board yomalizidwa. Kuphatikiza apo, kuyezetsa kwachilengedwe komanso kudalirika kumachitika kuti zitsimikizire kuti ma PCB okhazikika amatha kupirira zovuta.
Powombetsa mkota
Kupanga ma rigid-flex board kumafunikira njira zapadera zopangira. Mapangidwe ovuta komanso mawonekedwe apadera a matabwa apamwambawa amafunikira kusamalitsa kamangidwe kake, kusankha kolondola kwazinthu ndi njira zopangira makonda. Potsatira njira zopangira izi, opanga zamagetsi amatha kugwiritsa ntchito mphamvu zonse za PCB zokhazikika ndikubweretsa mwayi watsopano wa zida zamagetsi zosinthika, zosinthika komanso zophatikizika.
