Flexible Printed Circuit board (Flexible Printed Circuit circuit yotchedwa FPC), yomwe imadziwikanso kuti flexible circuit board, flexible circuit board, ndi bolodi yodalirika kwambiri, yosinthika kwambiri yosindikizidwa yopangidwa ndi filimu ya polyimide kapena polyester monga gawo lapansi. Ili ndi mawonekedwe a kachulukidwe kakang'ono ka waya, kulemera kopepuka, makulidwe owonda komanso kupindika bwino.
Zosankha za FPC:
1.Kusankha kwazinthu za makiyi am'mbali / makiyi
M'mbali kiyi kusankha 18/12.5 mbali ziwiri electrolytic mkuwa (kupatula wapadera), main kiyi kusankha 18/12.5 mbali ziwiri electrolytic mkuwa (kupatula wapadera). Kiyi yam'mbali ndi kiyi yayikulu zilibe zofunikira zapadera pakupindika, ndipo zimagulitsidwa ndikukhazikika pa bolodi lalikulu, koma onetsetsani kuti palibe chosokoneza pakubweza mmbuyo ndi mtsogolo kuposa nthawi 8. Makulidwe a fungulo ali ndi zofunika kwambiri, apo ayi zidzakhudza kumverera kwa fungulo, choncho liyenera kukwaniritsa zofunikira zonse za makulidwe a kasitomala.
2.Kusankha kwazinthu za waya wolumikizira
Waya wolumikizira ndi 18 / 12.5 mbali ziwiri za electrolytic mkuwa (kupatula zapadera). Ntchito yayikulu ndikusewera gawo lolumikizana, ndipo palibe zofunikira zapadera pazofunikira zopindika. Mapeto onse awiriwa amatha kuwotcherera ndikukhazikika, koma ziyenera kutsimikiziridwa kuti palibe chosokoneza musanapindike mmbuyo ndi mtsogolo kwa nthawi zopitilira 8.
3.Kusankhidwa kwa zipangizo zothandizira
Posankha mapepala omatira, bolodi wamba safunikira SMT ikhoza kugwiritsa ntchito mapepala omatira osagwira kutentha kwambiri (monga bolodi lambali), ndipo kufunikira kwa SMT kuyenera kugwiritsa ntchito mapepala omatira osagwira kutentha kwambiri (monga SMT ndi bolodi lalikulu).
4.Kusankhidwa kwa zipangizo zopangira
Posankha pepala conductive, zomatira wamba conductive ndi oyenera amene ali ndi otsika magetsi madutsidwe zofunika (monga keyplate wamba), ndi katundu wabwino conductive ndi oyenera madutsidwe mphamvu madutsidwe magetsi ndipo ayenera kugwiritsa ntchito pepala zomatira (monga keyplate wapadera, etc.). ), koma pepala lomatira ili silimalimbikitsidwa chifukwa mtengo wake ndi wokwera kwambiri.
The conductive katundu wa nsalu conductive kungakhale, koma mamasukidwe akayendedwe si abwino, ndipo nthawi zambiri ndi oyenera kalasi keyplate.
Zomatira zoyera za conductive ndi zida zopangira mphamvu zambiri, zomwe zimagwiritsidwa ntchito polumikizira mapepala achitsulo, koma sizovomerezeka kugwiritsa ntchito zomatira zoyera za conductivezi, chifukwa mtengo wake ndi wokwera kwambiri.
5.Kusankha kwazinthu za mbale yotsetsereka
Chivundikiro chotsetsereka chokhala ndi zigawo ziwiri ndi 1/30Z mbali imodzi yopanda gel electrolytic copper, yomwe ndi yofewa komanso yodumphira. Chivundikiro chotsetsereka chokhala ndi mbali ziwiri ndi 1/30Z mkuwa wosamata wa mbali ziwiri wosamata, womwe ndi wofewa komanso wodumphira. Moyo wa chivundikiro chotsetsereka chopangidwa ndi 1/30Z mbali ziwiri za mkuwa wopanda electrolytic copper ndi wabwino kuposa wa 1/30Z mbali imodzi ya mkuwa wopanda electrolytic copper. Ngati palibe vuto ndi kapangidwe kake, tikulimbikitsidwa kupanga FPC ngati mbale yolowera mbali ziwiri momwe mungathere. Pankhani ya mtengo, kugwiritsa ntchito 1/30Z kawiri mbali mkuwa wopanda electrolytic mkuwa kumawonjezera mtengo ndi pafupifupi 30% poyerekeza ndi kugwiritsa ntchito 1/30Z single-mbali mkuwa wopanda electrolytic mkuwa chuma chachikulu, koma kugwiritsa ntchito zakuthupi zidzasintha zokolola, ndipo moyo woyesera ukhoza kukonzedwanso, zomwe zingatsimikizire kukhazikika kwa mbale iyi.
6.Kusankha kwazinthu zamagulu ambiri
Chophimba cha multilayer ndi 1/30Z non-colloidal electrolytic copper, yomwe ndi yofewa komanso ductile. Ngati palibe zovuta zamapangidwe, kupanga kwa flap kumatha kuyesedwa.
