Simuyenera kudziwa kusiyana pakati pa PCB ndi FPC

Ponena za PCB, otchedwabolodi losindikizidwanthawi zambiri amatchedwa bolodi lolimba.Ndilo bungwe lothandizira pakati pa zipangizo zamagetsi ndipo ndizofunikira kwambiri pakompyuta.Ma PCB nthawi zambiri amagwiritsa ntchito FR4 ngati maziko, omwe amatchedwanso hard board, omwe sangathe kupindika kapena kupindika.PCB nthawi zambiri amagwiritsidwa ntchito m'malo ena omwe safunikira kupindika koma amakhala ndi mphamvu zolimba, monga mavabodi apakompyuta, mavabodi amafoni am'manja, ndi zina zambiri.

FPC kwenikweni ndi mtundu wa PCB, koma ndiyosiyana kwambiri ndi bolodi yosindikizidwa yachikhalidwe.Imatchedwa bolodi yofewa, ndipo dzina lake lonse ndi bolodi losinthasintha.FPC nthawi zambiri imagwiritsa ntchito PI ngati maziko, chomwe ndi chinthu chosinthika chomwe chimatha kupindika ndikusinthidwa mosasamala.FPC nthawi zambiri imafuna kupindika mobwerezabwereza ndi ulalo wa tizigawo tating'ono, koma tsopano ndiyoposa pamenepo.Pakalipano, mafoni anzeru akuyesera kupewa kupindika, zomwe zimafuna kugwiritsa ntchito FPC, ukadaulo wofunikira.

M'malo mwake, FPC sikuti ndi bolodi losinthika lokha, komanso njira yofunikira yolumikizira magawo atatu azithunzi.Kapangidwe kameneka kakhoza kuphatikizidwa ndi zojambula zina zamagetsi zamagetsi kuti apange mitundu yosiyanasiyana ya ntchito.Chifukwa chake, kuchokera pamalingaliro awa Onani, ma FPC ndi osiyana kwambiri ndi ma PCB.

Kwa PCB, pokhapokha ngati dera lipangidwa kukhala mawonekedwe amitundu itatu podzaza guluu wafilimu, bolodi lozungulira nthawi zambiri limakhala lathyathyathya.Chifukwa chake, kuti mugwiritse ntchito mokwanira danga la magawo atatu, FPC ndi yankho labwino.Ponena za matabwa olimba, njira yowonjezereka yowonjezera malo ndikugwiritsa ntchito mipata ndikuwonjezera makadi owonetsera, koma FPC ikhoza kupanga mapangidwe ofanana ndi mapangidwe osinthira, ndipo mapangidwe otsogolera amakhalanso osinthasintha.Pogwiritsa ntchito FPC imodzi yolumikizira, matabwa awiri olimba amatha kulumikizidwa kuti apange dongosolo la mzere wofananira, ndipo amathanso kusinthidwa kukhala ngodya iliyonse kuti agwirizane ndi mapangidwe osiyanasiyana azinthu.

Zachidziwikire, FPC imatha kugwiritsa ntchito kulumikizana kwa ma terminal polumikizira mizere, koma imathanso kugwiritsa ntchito matabwa ofewa komanso olimba kuti ipewe njira zolumikizira izi.FPC imodzi imatha kukhazikitsidwa ndi ma hard board ambiri ndikulumikizidwa ndi masanjidwe.Njirayi imachepetsa kusokoneza kwa zolumikizira ndi ma terminals, zomwe zitha kupititsa patsogolo mtundu wazizindikiro komanso kudalirika kwazinthu.Chithunzichi chikuwonetsa bolodi yofewa komanso yolimba yopangidwa ndi ma multi-chip PCB ndi mawonekedwe a FPC.
