Flexible Print Circuit

Flexible Print Circuit，Ikhoza kupindika, kuvulala ndi kupindika momasuka.The flexible circuit board imakonzedwa pogwiritsa ntchito filimu ya polyimide ngati maziko.Imatchedwanso soft board kapena FPC pamakampani.The ndondomeko otaya wa bolodi kusintha dera lagawidwa Awiri-mbali mbali kusintha dera bolodi ndondomeko, Mipikisano wosanjikiza kusintha dera bolodi ndondomeko.FPC yofewa board imatha kupirira mamiliyoni akupindika kosunthika popanda kuwononga mawaya.Ikhoza kukonzedwa mosasamala malinga ndi zofunikira za danga la danga, ndipo ikhoza kusuntha ndi kutambasulidwa mopanda malire mu malo atatu-dimensional, kuti akwaniritse kusakanikirana kwa gawo limodzi ndi kugwirizana kwa waya;gulu losinthasintha dera likhoza kukhala Kukula ndi kulemera kwa zinthu zamagetsi zimachepetsedwa kwambiri, ndipo ndizoyenera kupanga zinthu zamagetsi motsogozedwa ndi kachulukidwe kakang'ono, miniaturization ndi kudalirika kwakukulu.

Kapangidwe ka matabwa osinthika: malinga ndi kuchuluka kwa zigawo za zojambulazo zamkuwa, zitha kugawidwa m'magulu osanjikiza amodzi, matabwa amitundu iwiri, matabwa amitundu yambiri, matabwa ambali ziwiri, etc.

Zinthu zakuthupi ndi njira zosankha:

(1) Gawo laling'ono: Zinthu zake ndi polyimide (POLYMIDE), yomwe ndi yosagwira kutentha kwambiri, yamphamvu kwambiri ya polima.Ikhoza kupirira kutentha kwa madigiri 400 Celsius kwa masekondi 10, ndipo mphamvu yothamanga ndi 15,000-30,000PSI.25μm wandiweyani magawo ndi otsika mtengo komanso ogwiritsidwa ntchito kwambiri.Ngati gulu lozungulira likufunika kukhala lolimba, gawo lapansi la 50 μm liyenera kugwiritsidwa ntchito.Mosiyana ndi zimenezi, ngati bolodi la dera liyenera kukhala lofewa, gwiritsani ntchito gawo lapansi la 13μm

(2) guluu Transparent pazinthu zoyambira: Amagawidwa m'mitundu iwiri: epoxy resin ndi polyethylene, onse omwe ndi guluu wa thermosetting.Mphamvu ya polyethylene ndi yochepa.Ngati mukufuna kuti gulu lozungulira likhale lofewa, sankhani polyethylene.Kukhuthala kwa gawo lapansi ndi guluu wowoneka bwino pamenepo, bolodi limakhala lolimba.Ngati bwalo la dera lili ndi malo opindika kwambiri, muyenera kuyesa kugwiritsa ntchito gawo lapansi locheperako komanso guluu wowonekera kuti muchepetse kupsinjika pamwamba pa zojambulazo zamkuwa, kuti mwayi wang'ono-ming'alu muzojambula zamkuwa ndi wochepa.Inde, kumadera oterowo, matabwa amtundu umodzi ayenera kugwiritsidwa ntchito momwe angathere.

(3) Copper zojambulazo: anagulung'undisa mkuwa ndi electrolytic mkuwa.Mkuwa wokulungidwa uli ndi mphamvu zambiri ndipo sugonja kupindika, koma ndi wokwera mtengo.Electrolytic copper ndi yotsika mtengo kwambiri, koma mphamvu yake ndi yochepa ndipo ndiyosavuta kusweka.Amagwiritsidwa ntchito nthawi zambiri pomwe pali kupindika pang'ono.Kusankha kwa makulidwe a zojambula zamkuwa kumadalira m'lifupi mwake komanso katalikirana kakang'ono ka mayendedwe.Kuonda kwa zojambulazo zamkuwa, kumachepetsa m'lifupi zotheka zotheka ndi katayanitsidwe.Posankha mkuwa wokutidwa, tcherani khutu kumayendedwe a zojambulazo zamkuwa.Mayendedwe opindika a zojambula zamkuwa ayenera kukhala ogwirizana ndi njira yayikulu yopindika ya bolodi yozungulira.

(4) Kanema woteteza ndi guluu wake wowonekera: Filimu yoteteza ya 25 μm ipangitsa gulu ladera kukhala lolimba, koma mtengo wake ndi wotsika mtengo.Kwa matabwa ozungulira omwe ali ndi zopindika zazikulu, ndi bwino kugwiritsa ntchito filimu yoteteza 13μm.Mandala guluu nawonso anawagawa mitundu iwiri: epoxy utomoni ndi polyethylene.Bolodi yogwiritsira ntchito epoxy resin ndiyovuta.Kukanikiza kotentha kumalizidwa, guluu wina wowonekera adzatulutsidwa m'mphepete mwa filimu yoteteza.Ngati kukula kwa pediyo kuli kwakukulu kuposa kukula kotsegulira kwa filimu yotetezera, guluu lotulutsidwa limachepetsa kukula kwa pedi ndikupangitsa kuti m'mphepete mwake mukhale osasinthasintha.Panthawi imeneyi, yesani kugwiritsa ntchito guluu mandala ndi makulidwe a 13 μm.

(5) Pad plating: Kwa matabwa ozungulira okhala ndi zopindika zazikulu komanso zopendekera zowonekera, payenera kugwiritsidwa ntchito nickel ya electroplating + mankhwala agolide, ndipo wosanjikiza wa faifi ayenera kukhala woonda momwe angathere: 0.5-2μm, wosanjikiza wagolide wamankhwala 0.05-0.1 μm .
