FCCL polyimide film covered membrane product structure
Flexible copper clad laminates (FCCL) are primarily composed of three main material categories
2025-03-21
Flexible copper clad laminates (FCCL) are primarily composed of three main material categories: Insulating base film materials: Insulating base film materials used in FCCL include polyester (PET) film, polyimide (PI) film, polyesterimide film, fluorocarbon ethylene film, polyimide fiber paper, polybutylene terephthalate film, etc. Currently, the most widely used are polyester film (PET film) and polyimide film (PI film).
Metal conductor foil
Metal conductor foil is the conductor material used in FCCL, including copper foil (ordinary electrolytic copper foil, high ductility electrolytic copper foil, rolled copper foil), aluminum foil, and copper-beryllium alloy foil. Currently, the vast majority use copper foil, including electrolytic copper foil (ED) and rolled copper foil (RA).
Adhesive
Adhesive is an important component of three-layer FCCL, directly affecting the product performance and quality. Currently, the main adhesives used in FCCL include polyester adhesives, acrylic adhesives, epoxy or modified epoxy adhesives, polyimide adhesives, and phenolic-butyraldehyde adhesives. Currently, in the three-layer FCCL industry, adhesives are mainly divided into two schools: acrylic adhesives and epoxy adhesives.
