WebNov 4, 2024 · Hence, FR-1 requires a precise calculation of the maximum electrical properties the circuit board will operate. If the voltage, power or heat of the circuit board exceeds the limit of FR-1 PCB material, the material will face a dielectric breakdown. Due to the dielectric breakdown, FR-1 will initiate to lose its insulating properties. WebA standard FR-4 PCB will have a layer of FR-4 sandwiched between two thin layers of laminated copper. FR-4 uses bromine, a so-called halogen chemical element that is fire resistant. It replaced G-10, another composite that was less resistant, in most of its applications. FR4 has the advantage of having a good resistance-weight ratio.
