Chidziwitso chofunikira cha PCB: FPC yofewa board ndi bolodi yofewa komanso yolimba ndi chiyani

Ndikukhulupirira kuti anthu omwe amagwira ntchito m'makampani opanga zamagetsi amadziwabe bwino matabwa ozungulira.Kaya mukuchita nawo mapulogalamu kapena ma hardware, simungathe kuchita popanda matabwa ozungulira, koma anthu ambiri amatha kulumikizana ndi matabwa wamba.Ndawonapo kapena sindinamvepo za bolodi yofewa ya FPC komanso bolodi yosakanikirana yofewa.Ndiroleni ndikudziwitseni kuti FPC yofewa ndi bolodi yosakanikirana ndi yofewa.Kodi pali kusiyana kotani pakati pawo ndi matabwa wamba wamba?Zomwe ziyenera kutsatiridwa popanga PCB Mukuyembekezera chiyani?

FPC yofewa bolodi ndi bolodi yosakanikirana yofewa imakhalanso m'gulu la matabwa ozungulira, omwe amagwiritsidwa ntchito pazochitika zapadera.Tisanatchule bolodi yofewa ya FPC ndi bolodi yophatikizira yolimba, choyamba timvetsetse kuti board board ndi chiyani?

matabwa ozungulira akhoza kugawidwa mu: ceramic matabwa, aluminiyamu ceramic matabwa, zotayidwa nitride ceramic dera matabwa, matabwa dera, PCB matabwa, zotayidwa magawo, mkulu-pafupipafupi matabwa, wandiweyani mkuwa matabwa, impedance matabwa, PCBs, kopitilira muyeso-woonda matabwa dera. , matabwa a ultra-thin circuit, osindikizidwa (teknoloji ya copper etching) matabwa ozungulira, ndi zina zotero, angapezeke mu chipangizo chilichonse chamagetsi, ndikuthandizira kukonza ndi kulumikiza zipangizo zamagetsi mu dera.

Chotsatira, tiyeni choyamba tidziwitse kuti FPC yofewa board ndi chiyani.

FPC circuit board, yomwe imadziwikanso kuti flexible circuit board, ndi bolodi yodalirika komanso yosinthika kwambiri yosindikizidwa yopangidwa ndi filimu ya polyimide kapena poliyesitala ngati maziko.Iwo ali ndi makhalidwe a mkulu kachulukidwe mawaya, kulemera kuwala, makulidwe woonda ndi bendability wabwino, ndipo makamaka ntchito kugwirizana ndi matabwa ena dera.FPC yofewa board imatha kupulumutsa malo amkati azinthu zamagetsi pamlingo wina, kupangitsa msonkhano ndi kukonza zinthu kukhala zosinthika.Mwachitsanzo, LCD/OLED ndi AMOLED zowonetsera zowonetsera mu mafoni a m'manja zimagwirizanitsidwa kudzera pa mapepala ofewa a FPC, omwe amagwiritsidwa ntchito kwambiri m'makompyuta apakompyuta, makamera a digito, ndi zachipatala, zamagalimoto, zamlengalenga ndi zina.

Titatha kumvetsetsa bwino bolodi lofewa, n'zosavuta kumvetsetsa bolodi lofewa komanso lolimba.Monga dzinalo limatanthawuzira, bolodi yofewa ndi yolimba imatanthawuza bolodi losinthasintha lozungulira ndi bolodi lokhazikika.Pambuyo kukanikiza ndi njira zina, zimaphatikizidwa malinga ndi zofunikira za ndondomekoyi., kupanga gulu lozungulira lomwe lili ndi mawonekedwe a FPC ndi mawonekedwe a PCB.

Gulu lokhazikika lokhazikika lili ndi mawonekedwe onse a FPC ndi PCB.Choncho, angagwiritsidwe ntchito zinthu zina ndi zofunika zapadera.Ili ndi malo ena osinthika komanso malo ena okhwima, omwe amasunga malo amkati mwazogulitsa ndikuchepetsa Kuchuluka kwa zinthu zomwe zatsirizidwa ndizothandiza kwambiri kupititsa patsogolo ntchito ya mankhwala, koma kupanga kolimba-flex. bolodi ndi zovuta ndipo mlingo zokolola ndi otsika, choncho mtengo wake ndi okwera mtengo ndipo mkombero kupanga ndi yaitali.

Titamvetsetsa kuti bolodi yofewa ya FPC ndi bolodi yofewa komanso yolimba ndi chiyani, tifunika kusamala chiyani pamapangidwe enieni?

Zinthu zomwe muyenera kuziganizira mukamapanga:

1. Chipangizocho chiyenera kuikidwa m'dera lolimba, ndipo malo osinthika amangogwiritsidwa ntchito kuti agwirizane, zomwe zingathe kusintha moyo wa bolodi ndikuwonetsetsa kudalirika kwa bolodi.Ngati chipangizocho chikayikidwa pamalo osinthika, zimakhala zosavuta kuti pad iwonongeke kapena kuti zilembo zigwe.

2. Pamene chipangizocho chikuyikidwa pamalo ovuta, payenera kukhala mtunda wa 1mm kuchokera kumalo ofewa ndi ovuta.

Mukamapanga wiring, muyenera kulabadira:

1. Zithunzi zomwe zili m'dera lofewa ziyenera kukhala zosachepera 10mil kuchokera pamphepete mwa bolodi, palibe mabowo omwe angabowole, ndipo mtunda wapakati pa dzenje ndi mgwirizano pakati pa zofewa ndi zolimba ndi zosachepera 2mm.

2. Mizere mu malo osinthika a bolodi iyenera kukhala yosalala, ndipo ngodya ziyenera kugwirizanitsidwa ndi ma arcs ozungulira.Panthawi imodzimodziyo, mizere yowongoka ndi ma arcs ayenera kukhala ofukula, ndipo mapepala ayenera kuchitidwa ndi misozi kuti asagwe.

3. Pamphepete mwa malo osinthasintha, zojambulazo zamkuwa ziyenera kugwiritsidwa ntchito kulimbikitsa kugwirizana pamtunda wa kugwirizana.

4. Kuti muthe kusinthasintha bwino, malo opindika ayenera kupewa kusintha kwa m'lifupi mwa kufufuza ndi kufufuza kosafanana.

5. Mawaya omwe ali pansi pa tebulo ayenera kugwedezeka momwe angathere kuti asadutse mizere yomwe ili pansi pa tebulo.
