Kuyamba kwa zida za FR4
FR mu FR4 imayimira moto woyaka moto, ndipo chiwerengero cha 4 chimasiyanitsa zinthu ndi zipangizo zina za m'kalasili.FR4 ndi galasi fiber reinforced epoxy laminate yomwe imawoneka ngati nsalu yopyapyala yopangidwa ndi nsalu.Mawu akuti FR4 akuyimiranso kalasi yomwe imagwiritsidwa ntchito popanga ma laminate awa.Mapangidwe a fiberglass amapereka kukhazikika kwazinthuzo.Ulusi wagalasi umakutidwa ndi epoxy yoletsa moto.Izi zimapereka zinthu durability ndi amphamvu makina katundu.Zonsezi zimapangitsa gulu la FR4 losindikizidwa kukhala lodziwika kwambiri pakati pa opanga mapangano amagetsi.
Gulu losindikizidwa la FR4 limadziwikanso pazifukwa izi:
FR4 ndi zinthu zotsika mtengo.
1, Ili ndi mphamvu ya dielectric yayikulu, yomwe imathandizira kuti magetsi azigwira ntchito.
2, Zinthuzo zimakhala ndi mphamvu zolemera kwambiri komanso zopepuka.
3, Imateteza chinyezi ndipo imakhala ndi kutentha pang'ono.
4, Zinthuzo zili ndi katundu wabwino wamagetsi.
5, FR4 sichimamwa madzi, kotero ndiyoyenera kugwiritsa ntchito mitundu yonse ya Marine PCB.
6, zida ndi zachikasu mpaka zobiriwira zobiriwira, zabwino pakugwiritsa ntchito kulikonse.Zonsezi zimapangitsa kuti zikhale zoyenera kumadera osiyanasiyana.
Kodi FR4 imapangidwa bwanji pama board osindikizira a FR4?FR4 imakhala ngati maziko a PCB iliyonse.Zinthuzo ndi laminated ndi zojambulazo zamkuwa.Gwiritsani ntchito kutentha ndi zomatira ku laminate.Chojambula chamkuwa chingagwiritsidwe ntchito kupangira zinthu kuchokera kumbali imodzi kapena zonse.
