FPC flexible boardndi mawonekedwe ozungulira opangidwa pamtunda wosinthika, wokhala ndi kapena wopanda chivundikiro (nthawi zambiri amagwiritsidwa ntchito kuteteza mabwalo a FPC). Chifukwa bolodi yofewa ya FPC imatha kupindika, kupindika kapena kubwereza mobwerezabwereza m'njira zosiyanasiyana, poyerekeza ndi bolodi wamba (PCB), ili ndi zabwino zake zopepuka, zoonda, zosinthika, kotero kugwiritsa ntchito kwake kumachulukirachulukira, kotero tiyenera tcherani khutu ku zomwe timapanga, zotsatirazi zazing'ono zimapanga kunena mwatsatanetsatane.
Pamapangidwe, FPC nthawi zambiri imayenera kugwiritsidwa ntchito ndi PCB, polumikizana pakati pa awiriwo nthawi zambiri amatengera cholumikizira cholumikizira bolodi, cholumikizira ndi chala chagolide, HOTBAR, bolodi yofewa ndi yolimba, yolumikizirana ndi manja, njira yowotcherera yolumikizira, malinga ndi zosiyanasiyana ntchito chilengedwe, mlengi akhoza kutengera lolingana kugwirizana mode.
Muzogwiritsa ntchito, zimatsimikiziridwa ngati chitetezo cha ESD chikufunika malinga ndi zomwe mukufuna. Ngati kusinthasintha kwa FPC sikuli kokwera, khungu lolimba lamkuwa ndi sing'anga yokhuthala zitha kugwiritsidwa ntchito kuti zitheke. Pamene kufunikira kwa kusinthasintha kuli kwakukulu, mauna amkuwa ndi phala la siliva la conductive lingagwiritsidwe ntchito
Chifukwa cha kufewa kwa mbale yofewa ya FPC, ndiyosavuta kusweka ndi kupsinjika, kotero njira zina zapadera zimafunikira chitetezo cha FPC.
Njira zodziwika bwino ndi izi:
1. Utali wocheperako wa Angle wamkati wa flexible contour ndi 1.6mm. Kukula kwakukulu kwa radius, kumapangitsa kudalirika komanso kumapangitsa kuti misozi ikhale yolimba. Mzere ukhoza kuwonjezeredwa pafupi ndi m'mphepete mwa mbale pakona ya mawonekedwe kuti FPC isang'ambika.
2. Ming’alu kapena mipope ya mu FPC iyenera kuthera mu dzenje lozungulira losachepera 1.5mm m’mimba mwake, ngakhale ma FPCS awiri oyandikana akufunika kusuntha padera.
3. Kuti muthe kusinthasintha bwino, malo opindika ayenera kusankhidwa m'derali ndi m'lifupi mwake, ndipo yesetsani kupewa kusiyana kwa FPC m'lifupi ndi kusasunthika kwa mzere wosiyana m'dera lopindika.
STIffener board imagwiritsidwa ntchito pothandizira kunja. Zida STIffener bolodi zikuphatikizapo PI, poliyesitala, galasi CHIKWANGWANI, polima, pepala aluminiyamu, pepala zitsulo, etc. wololera kamangidwe ka malo, dera ndi zinthu za mbale kulimbikitsa kumathandiza kwambiri kupewa FPC kung'amba.
5. Pamapangidwe amitundu yambiri ya FPC, mapangidwe apakati a mpweya amayenera kuchitidwa kumadera omwe amafunikira kupindika pafupipafupi pakugwiritsa ntchito mankhwalawa. Zinthu zoonda za PI ziyenera kugwiritsidwa ntchito momwe zingathere kuti muwonjezere kufewa kwa FPC ndikuletsa FPC kuti isasweke popinda mobwerezabwereza.
6. Ngati danga likuloleza, malo omata a mbali ziwiri ayenera kupangidwa polumikiza chala chagolide ndi cholumikizira kuti chala chagolide ndi cholumikizira zisagwe popinda.
7. FPC yoyika zenera la silika iyenera kupangidwa polumikizana pakati pa FPC ndi cholumikizira kuletsa kupatuka ndi kuyika molakwika kwa FPC panthawi yolumikizana. Zothandizira kuwunika kwa kupanga.
Chifukwa cha mawonekedwe a FPC, tcherani khutu ku mfundo zotsatirazi mukamayendetsa:
Malamulo oyendetsera: Perekani patsogolo kuonetsetsa kuti ma siginecha akuyenda mosalala, tsatirani mfundo ya mabowo aafupi, owongoka ndi ochepa, pewani njira yayitali, yopyapyala komanso yozungulira momwe mungathere, tengani mizere yopingasa, yoyima ndi ma degree 45 monga chachikulu, pewani mzere wongolowera pang'onopang'ono. , pindani gawo la mzere wa radian, zomwe zili pamwambapa ndi izi:
1. Mzere wa mzere: Poganizira kuti zofunikira za mzere wa mzere wa chingwe cha deta ndi chingwe cha mphamvu ndizosagwirizana, malo ambiri omwe amasungirako mawaya ndi 0.15mm
2. Kutalikirana kwa mizere: Malinga ndi kuchuluka kwa opanga opanga ambiri, katayanidwe ka mzere (Pitch) ndi 0.10mm
3. Mphepete mwa mzere: mtunda pakati pa mzere wakunja ndi FPC contour wapangidwa kukhala 0.30mm. Malo aakulu amalola, bwino
4. Fillet yamkati: Fillet yocheperako mkati mwa FPC contour idapangidwa ngati utali wa R=1.5mm
5. Woyendetsa ndi perpendicular kwa njira yopindika
6. Wayayo uyenera kudutsa mozungulira malo opindika
7. Kondakitala ayenera kuphimba malo opindika momwe angathere
8. Palibe chitsulo chowonjezera pamalo opindika (mawaya omwe ali pamalo opindika sali plating)
9. Sungani mzere m'lifupi mofanana
10. Kulumikizana kwa mapanelo awiriwa sikungafanane kupanga mawonekedwe a "I".
11. Chepetsani kuchuluka kwa zigawo mu malo opindika
12. Sipadzakhalanso mabowo ndi mabowo azitsulo pamalo opindika
13. Mzere wopindika wapakati udzakhazikitsidwa pakati pa waya. Coefficient yakuthupi ndi makulidwe mbali zonse za woyendetsa ziyenera kukhala zofanana momwe zingathere. Izi ndizofunikira kwambiri pamapulogalamu opindika.
14. Kugwedeza kozungulira kumatsatira mfundo zotsatirazi ---- kuchepetsa gawo lopindika kuti muwonjezere kusinthasintha, kapena kuonjezera pang'ono malo opangidwa ndi mkuwa kuti muwonjezere kulimba.
15. Mapiritsi opindika a ndege yoyimirira achulukitsidwe ndipo kuchuluka kwa zigawo zapakati papindika ziyenera kuchepetsedwa.
16. Pazinthu zomwe zili ndi zofunikira za EMI, ngati mizere yamagetsi yamagetsi yapamwamba kwambiri monga USB ndi MIPI ili pa FPC, wosanjikiza wa siliva wa conductive ayenera kuwonjezeredwa ndi kukhazikika pa FPC molingana ndi muyeso wa EMI kuteteza EMI.
