PI Reinforcement Board

PI Reinforcement Board is an auxiliary part for electronic components made of high performance polyimide material, designed to enhance the structural strength, thermal stability and long-term reliability of flexible circuit boards (FPCs) and other precision electronic assemblies.It has excellent heat resistance, good mechanical properties, flatness, chemical resistance, stable electrical properties, halogen-free and antimony-free, environmental protection and flame retardant, strong adaptability, thinness and flexibility, long-term reliability and other characteristics.

Features:

Excellent electrical insulation and dielectric properties.
High mechanical strength and dimensional stability.
Resistant to chemicals, oils, and solvents.
Low outgassing, suitable for cleanroom and aerospace applications.
Flame retardant and self-extinguishing properties.

Applications:

Structural reinforcement for flexible printed circuits (FPC), Spacer and support plates in lithium battery packs, Insulation boards for high-temperature electrical equipment, Reinforcement in aerospace, automotive, and electronic assemblies, Precision parts in semiconductor manufacturing equipment.
