Njira yowerengera yopindika ya fpc

FPC flexible circuit board ikapindika, mitundu yopanikizika mbali zonse za mzere wapakati ndi yosiyana.

Izi zimachitika chifukwa cha mphamvu zosiyanasiyana zomwe zimagwira mkati ndi kunja kwa malo opindika.

Kumbali yamkati ya malo opindika, FPC imakumana ndi kupsinjika.Izi zili choncho chifukwa zinthuzo zimapanikizidwa ndikufinyidwa pamene zipinda mkati.Kuponderezedwa kumeneku kungapangitse kuti zigawo za FPC zipanikizidwe, zomwe zingayambitse delamination kapena kusweka kwa chigawocho.

Kunja kwa malo opindika, FPC imakumana ndi kupsinjika kwamphamvu.Zili choncho chifukwa chakuti zinthuzo zimatambasulidwa zikapindika kunja.Kufufuza kwa mkuwa ndi zinthu zoyendetsera kunja kungakhale ndi zovuta zomwe zingasokoneze kukhulupirika kwa dera.Kuti muchepetse kupsinjika kwa FPC panthawi yopindika, ndikofunikira kupanga mawonekedwe osinthika pogwiritsa ntchito zida zoyenera ndi njira zopangira.Izi zikuphatikiza kugwiritsa ntchito zida zosinthika koyenera, makulidwe oyenera, ndikuganizira utali wocheperako wa FPC.Kulimbitsa kokwanira kapena zomangira zothandizira zitha kukhazikitsidwanso kuti zigawidwe molingana mozungulira dera lonselo.

Pomvetsetsa mitundu ya kupsinjika maganizo ndikuganiziranso kamangidwe koyenera, kudalirika ndi kulimba kwa ma FPC flexible circuit boards pamene akupindika kapena kusinthasintha akhoza kusintha.

Zotsatirazi ndi zina mwamapangidwe omwe angathandize kukonza kudalirika ndi kulimba kwa ma board a FPC osinthika akapindika kapena kusinthasintha:

Zosankha:Kusankha zinthu zoyenera n’kofunika kwambiri.Gawo laling'ono losinthika lomwe lili ndi kusinthasintha kwabwino komanso mphamvu zamakina ziyenera kugwiritsidwa ntchito.Flexible polyimide (PI) ndi chisankho chofala chifukwa cha kukhazikika kwake komanso kusinthasintha kwake.

Mawonekedwe Ozungulira:Kukonzekera koyenera kozungulira ndikofunikira kuti kuwonetsetse kuti ma conductive ndi zigawo zake zimayikidwa ndikuyendetsedwa m'njira zomwe zimachepetsa kupsinjika panthawi yopindika.Ndibwino kugwiritsa ntchito ngodya zozungulira m'malo mwa ngodya zakuthwa.

Zowonjezera ndi Zothandizira:Kuonjezera kulimbikitsa kapena zida zothandizira m'malo opindika ovuta kungathandize kugawanitsa nkhawa mofananamo ndikupewa kuwonongeka kapena kuwononga.Zowonjezera zigawo kapena nthiti zingagwiritsidwe ntchito kumadera ena kuti zikhale bwino kwambiri.

Radius yopindika:Ma radii opindika ochepa amayenera kufotokozedwa ndikuganiziridwa panthawi yopanga.Kupitilira utali wocheperako wopindika kumabweretsa kupsinjika kwambiri komanso kulephera.

Chitetezo ndi Kukhazikika:Chitetezo monga zokutira zovomerezeka kapena zotsekera zimatha kupereka mphamvu zowonjezera zamakina ndikuteteza mabwalo kuzinthu zachilengedwe monga chinyezi, fumbi, ndi mankhwala.

Kuyesa ndi Kutsimikizira:Kuyesa ndi kutsimikizira kwathunthu, kuphatikiza kuyesa kwamakina ndi kusinthasintha, kungathandize kuwunika kudalirika komanso kulimba kwa ma board osinthika a FPC pansi pa zochitika zenizeni.

Mkati mwa malo okhotakhota ndi kupanikizika, ndipo kunja kumakhala kovuta.Kukula kwa kupsinjika kumayenderana ndi makulidwe ndi mapindikidwe opindika a FPC flexible circuit board.Kupanikizika kwambiri kumapangitsa FPC kusinthasintha kwa board board, kuphulika kwa zojambulazo zamkuwa ndi zina zotero.Choncho, mawonekedwe a lamination a FPC flexible circuit board ayenera kukonzedwa momveka bwino, kotero kuti malekezero awiri a mzere wapakati wa malo opindika ayenera kukhala ofanana momwe angathere.Panthawi imodzimodziyo, utali wopindika wocheperako uyenera kuwerengedwa molingana ndi zochitika zosiyanasiyana zogwiritsira ntchito.

Mkhalidwe 1. Kupindika pang'ono kwa bolodi yozungulira ya FPC ya mbali imodzi ikuwonetsedwa pachithunzi chotsatirachi:

Utali wake wocheperako wopindika ukhoza kuwerengedwa motsatira njira iyi: R= (c/2) [(100-Eb) /Eb]-D
Utali wocheperako wopindika wa R=, makulidwe a c= khungu lamkuwa (unit m), makulidwe a D= filimu yophimba (m), kupunduka kovomerezeka kwa EB= khungu lamkuwa (loyesedwa ndi peresenti).

Kusintha kwa khungu lamkuwa kumasiyana ndi mitundu yosiyanasiyana yamkuwa.
The mapindikidwe pazipita A ndi mbamuikha mkuwa ndi zosakwana 16%.
The mapindikidwe pazipita B ndi electrolytic mkuwa ndi zosakwana 11%.

Komanso, mkuwa wa zinthu zomwezo umakhalanso wosiyana muzochitika zosiyanasiyana zogwiritsira ntchito.Kwa nthawi yopindika kamodzi, mtengo wocheperako wa fracture wovuta umagwiritsidwa ntchito (mtengo wake ndi 16%).Pamapangidwe oyika opindika, gwiritsani ntchito mtengo wocheperako wotchulidwa ndi IPC-MF-150 (mkuwa wopindidwa, mtengo wake ndi 10%).Kwa ntchito zosinthika zosinthika, kusinthika kwa khungu lamkuwa ndi 0.3%.Pogwiritsa ntchito maginito mutu, mapindikidwe a khungu lamkuwa ndi 0.1%.Pokhazikitsa kusinthika kovomerezeka kwa khungu lamkuwa, utali wocheperako wa kupindika ukhoza kuwerengedwa.

Kusinthasintha kwamphamvu: zomwe zidachitika pakhungu lamkuwa zimazindikirika ndi mapindikidwe.Mwachitsanzo, chipolopolo cha phosphor mu IC khadi ndi gawo la IC khadi lolowetsedwa mu chip pambuyo pa kuyika kwa IC khadi.Poikapo, chipolopolocho chimapunduka mosalekeza.Pulogalamuyi ndi yosinthika komanso yamphamvu.

Kupindika kochepa kwa PCB yosinthika ya mbali imodzi kumatengera zinthu zingapo, kuphatikiza zinthu zomwe zimagwiritsidwa ntchito, makulidwe a bolodi, komanso zofunikira pakugwiritsa ntchito.Nthawi zambiri, ma radius opindika a bolodi yosinthika amakhala pafupifupi nthawi 10 kukula kwa bolodi.Mwachitsanzo, ngati makulidwe a bolodi ndi 0.1mm, utali wopindika wocheperako ndi pafupifupi 1mm.Ndikofunika kuzindikira kuti kupindika bolodi pansi pa utali wopindika wocheperako kumatha kubweretsa kupsinjika, kupsinjika kwa njira zotsatsira, mwinanso kusweka kapena kusokoneza bolodi.Kusunga kukhulupirika kwa magetsi ndi makina a dera, ndikofunikira kumamatira ku bend radii yovomerezeka.Ndibwino kuti mufunsane ndi wopanga kapena wogulitsa bolodi yosinthika kuti mupeze malangizo enaake opindika ndikuwonetsetsa kuti kapangidwe kake ndi zofunikira pakugwiritsa ntchito zikukwaniritsidwa.Kuphatikiza apo, kuyesa kwamakina ndikutsimikizira kungathandize kudziwa kupsinjika kwakukulu komwe bolodi ingapirire popanda kusokoneza magwiridwe antchito ake komanso kudalirika kwake.

Situation 2, board ya mbali ziwiri ya FPC flexible circuit board motere:

Zina mwa izo: R= utali wopindika pang'ono, unit m, c= makulidwe a khungu la mkuwa, unit m, D= makulidwe a filimu yophimba, unit mm, EB = kupunduka kwa khungu lamkuwa, kuyeza ndi kuchuluka.

Mtengo wa EB ndi wofanana ndi womwe uli pamwambapa.
D= interlayer medium makulidwe, unit M

Malo opindika ochepera a FPC (Flexible Printed Circuit) yokhala ndi mbali ziwiri (Flexible Printed Circuit) nthawi zambiri amakhala wamkulu kuposa gulu la mbali imodzi.Izi ndichifukwa choti mapanelo am'mbali ziwiri amakhala ndi zowonera mbali zonse ziwiri, zomwe zimakhala zosavuta kupsinjika komanso kupsinjika panthawi yopindika.Kupindika kochepa kozungulira kwa mbali ziwiri za FPC flex pcb baord nthawi zambiri kumakhala pafupifupi nthawi 20 kuposa makulidwe a bolodi.Pogwiritsa ntchito chitsanzo chomwecho kale, ngati mbale ndi 0.1mm wandiweyani, osachepera mapindikidwe utali wa pafupifupi 2mm.Ndikofunikira kwambiri kutsatira malangizo opanga ndi specifications kwa kupinda iwiri mbali FPC pcb matabwa.Kupitilira utali wopindika wopendekeka kumatha kuwononga njira zoyendetsera, kupangitsa kusanjikiza, kapena kuyambitsa zovuta zina zomwe zimakhudza magwiridwe antchito ndi kudalirika.Ndibwino kuti mufunsane ndi wopanga kapena wopereka malangizo kuti adziwe momwe mungayendetsere utali wa bend, ndikuyesa makina ndikutsimikizira kuti gululo limatha kupirira mapindikidwe ofunikira popanda kusokoneza magwiridwe ake.
