| Advantages︰ | FR4 parts extremely high mechanical strength (flexural,impact,and bonding) at room temperature,good dielectric loss and electric strength properties under both dry and humid conditions.This material is normally used for electrical and electronic insulation applications where low moisture absorption and high physical strength are needed.exhibits good organic solvent resistance and fair to poor resistance to acids and alkalies,heat resistance is fair where physical stress is not imposed,not recommended for wear applications. |
