FR-4, ndi malo ovomerezeka padziko lonse lapansi a fiberglass reinforced epoxy laminated yomwe imakhala yoziziritsa moto (yozimitsa yokha). Pambuyo powonjezera mkuwa wosanjikiza mbali imodzi kapena mbali zonse za fr4 gulu, imakhala Copper Clad Laminate (CCL), ndipo ichi ndi chinthu chopanda ma conductive pa bolodi losindikizidwa lomwe nthawi zambiri limasindikizidwa (PCB). Bolodi yosindikizidwa yogwiritsa ntchito FR4 ngati zinthu zoyambira idzatchulidwa"FR4 PCB".
Gulu la fr4 PCB limagwiritsidwa ntchito kuthandizira ndi kulumikiza zida zamagetsi zamagetsi pogwiritsa ntchito njira, mayendedwe, kapena ma siginecha okhazikika kuchokera ku gawo lapansi lovala ndi copper-clad laminate. Nthawi zina, PCB imatchedwanso Printed Wiring Board (PWB) kapena etching wiring board ngati palibe zida zowonjezera zamagetsi zomwe zidawonjezedwa.
Tekinoloje Yabwino Kwambiri imapereka mndandanda wabwino kwambiri wa fr4 board womwe umapezeka mumitundu yosiyanasiyana komanso mawonekedwe. Best Technologyfr4 wopanga mosamala amasankha khalidwe zopangira. Izi zimatithandiza kupanga fr4 board yomwe imakhala yopikisana kwambiri kuposa zinthu zina zamakampani. Zili ndi ubwino pakuchita mkati, mtengo, ndi khalidwe.
Mndandanda wabwino kwambiri wazinthu zamakono uli ndi zinthu zingapo zazing'ono. Zathufr4 pcb wopanga amasamala kwambiri kukhulupirika ndi mbiri yabizinesi. Ife mosamalitsa kulamulira khalidwe ndi kupanga mtengo wa kupanga. Zonsezi zimatsimikizira kuti bolodi ya fr4 ndiyodalirika komanso yotsika mtengo.
