M'dziko lomwe likukula mwachangu pazamagetsi, kufunikira kwa zida zogwira ntchito kwambiri, zophatikizika, komanso zodalirika zikuchulukirachulukira. Chimodzi mwazinthu zotere zomwe zapeza chidwi kwambiri ndi multilayer flexible printed circuit (FPC). Nkhaniyi ikuyang'ana zovuta za kupanga FPC yamitundu ingapo, ikuyang'ana kwambiri monga kumalizidwa kwapamwamba, makulidwe a bolodi, komanso kupanga, makamaka potengera magawo a chingwe choyesera.
Kumvetsetsa Multi-Layer FPC
Ma FPC amitundu yambiri ndi ofunikira pazida zamakono zamakono, zomwe zimapereka njira yopepuka komanso yosinthika pamapangidwe ovuta. Mosiyana ndi ma PCB okhazikika, ma FPC amitundu yambiri amatha kupindika ndi kupindika, kuwapanga kukhala abwino kugwiritsa ntchito ma foni a m'manja, zovala, ndi zida zina zophatikizika. Kutha kusintha zinthu izi kumathandizira opanga kuti akwaniritse zofunikira zenizeni, ndikuwonetsetsa kuti magwiridwe antchito amasiyanasiyana.
Zogulitsa Mwamakonda: Kugwirizana ndi Zosowa Zapadera
Kusintha mwamakonda kuli pamtima pakupanga mitundu yambiri ya FPC. Pulojekiti iliyonse ikhoza kukhala ndi zofunikira zapadera malinga ndi momwe ikugwiritsidwira ntchito, monga kukula, mawonekedwe, ndi magetsi. Opanga amagwira ntchito limodzi ndi makasitomala kuti apange mayankho ogwirizana omwe amakwaniritsa zomwe akufuna. Mgwirizanowu nthawi zambiri umaphatikizapo kukambirana mwatsatanetsatane za kagwiritsidwe ntchito ka FPC, malo omwe idzagwire ntchito, ndi malamulo aliwonse omwe akuyenera kutsatiridwa.
Pamapeto Pamwamba: Kufunika kwa ENIG 2uin
Chimodzi mwazinthu zofunika kwambiri pakupanga kwamitundu yambiri ya FPC ndikumaliza pamwamba. Chisankho chodziwika bwino cha ma FPC apamwamba kwambiri ndi kumaliza kwa Electroless Nickel Immersion Gold (ENIG), makamaka pa makulidwe a 2uin. Kumaliza kwapamwambaku kuli ndi zabwino zingapo:
Kulimbana ndi Corrosion:ENIG imapereka chitetezo chabwino kwambiri ku oxidation ndi dzimbiri, kuwonetsetsa kutalika kwa dera.
Solderability:Chosanjikiza cha golide chimapangitsa kuti chiwonjezeke, kupangitsa kuti zikhale zosavuta kulumikiza zigawo panthawi ya msonkhano.
Kutsika:Zomaliza za ENIG zimadziwika chifukwa cha kusalala kwawo, komwe ndikofunikira pakuwonetsetsa kulumikizana kodalirika pamapangidwe amitundu yambiri.
Posankha kumaliza kwa ENIG 2uin, opanga amatha kuwonetsetsa kuti ma FPC awo amitundu yambiri amakhalabe ndi magwiridwe antchito komanso odalirika m'moyo wawo wonse.
Makulidwe a Board: Kufunika kwa 0.3mm
Makulidwe a bolodi ndichinthu china chofunikira kwambiri pakupanga ma FPC angapo. Mafotokozedwe wamba ndi makulidwe a 0.3mm, omwe amakhudza kusinthasintha pakati pa kusinthasintha ndi kulimba. Kuchuluka kumeneku kumapangitsa kuti pakhale mapangidwe ovuta kwambiri pamene mukusunga umphumphu wofunikira pa ntchito zosiyanasiyana.
Ma matabwa owonda amakhala opindulitsa makamaka pazida zophatikizika pomwe malo amakhala okwera mtengo. Komabe, kukwaniritsa makulidwe oyenera kumafuna kulondola pakupanga kuonetsetsa kuti FPC imatha kupirira kupsinjika kwamakina popanda kusokoneza magwiridwe antchito.
Njira Yopangira: Kulondola ndi Kuwongolera Ubwino
Njira yopangira ma FPC amitundu yambiri imakhala ndi magawo angapo, iliyonse imafunikira chidwi chambiri. Nazi mwachidule njira zazikulu zomwe zikukhudzidwa:
Design ndi Prototyping: Njirayi imayamba ndi gawo la mapangidwe, pomwe akatswiri amapanga schematics ndi masanjidwe atsatanetsatane. Prototyping imalola kuyesa ndi kutsimikizira kapangidwe kake musanayambe kupanga zambiri.
Zosankha:Kusankha zipangizo zoyenera n'kofunika kwambiri. Mafilimu apamwamba kwambiri a polyimide kapena polyester nthawi zambiri amagwiritsidwa ntchito pazinthu zawo zamatenthedwe komanso zamagetsi.
Layer Stacking:M'ma FPC amitundu yambiri, zigawo zimayikidwa ndikulumikizidwa bwino. Gawoli ndi lofunika kwambiri powonetsetsa kuti kugwirizana kwa magetsi pakati pa zigawo ndi zodalirika.
Etching ndi Plating:Mawonekedwe ozungulira amapangidwa kudzera mu etching, ndikutsatiridwa ndi plating kuti apange makulidwe amkuwa oyenera.
Kumaliza Pamwamba:Pambuyo pa etching, kumaliza kwa ENIG kumayikidwa, kupereka chitetezo chofunikira komanso kugulitsa.
Kuyesa:Kuyesedwa kolimba kumachitidwa kuti awonetsetse kuti FPC ikukwaniritsa zofunikira zonse. Izi zikuphatikiza kuyezetsa magetsi, kuyesa kupsinjika kwamakina, komanso kuyesa njinga zamoto kutentha.
Kuyang'anira Komaliza ndi Kuwongolera Ubwino: Isanatumizedwe, FPC iliyonse imayesedwa komaliza kuti iwonetsetse kuti ikukwaniritsa zofunikira. Kuwongolera kwaubwino ndikofunikira kwambiri pakupangira kuti tipewe zolakwika ndikuwonetsetsa kudalirika.
Yesani Screen Cable Field Applications
Chimodzi mwazinthu zofunikira kwambiri zama FPC amitundu yambiri ndi gawo la chingwe choyesera. Zingwezi ndizofunikira polumikiza zigawo zosiyanasiyana m'malo oyesera, kuonetsetsa kuti zizindikiro zimaperekedwa molondola komanso moyenera. Kusinthasintha ndi kuphatikizika kwa ma FPC amitundu yambiri kumawapangitsa kukhala abwino kwa pulogalamuyi, kulola kuti aziyenda mosavuta ndikuyika m'malo othina.
Pakugwiritsa ntchito chingwe cha skrini yoyeserera, kudalirika kwa FPC ndikofunikira kwambiri. Kulephera kulikonse mu chingwe kumatha kubweretsa zotsatira zolakwika, zomwe zimapangitsa kuti zikhale kofunika kuti opanga azitsatira njira zowongolera zowongolera pakupanga.
