40′×48′ Cem-1 Epoxy glass laminated sheet with low cost used in FCP

40′×48′ Cem - 1 Epoxy Glass Laminate Sheet Suitable For Vacuum Circuit Breaker 1

Flexible Printed Circuit Board is also called FPC,is kind of printed circuit made of flexible insulating substrate. FPC meets the design requirements of smaller and higher density which helps to reduce the assembly process and increased reliability.FPC is the only way to solve the The miniaturization of electronic products,free to bend,wind,fold for million times but won't damage the conductor,it can move in three-dimensional space and scale.So as to achieve integration of the components assembly and wire connection.
Pultruded fiberglass tube has excellent Fire Retardant,excellent Voltage Resistance,excellent Heat Resistance,excellent Heat Resistance(Class F),excellent mechanical processability & high degree of automation processing,FR-4 sheet and FR-2 Bakelite plate are good materials for Rigid circuit board,FPC.
