The FCCL film based on polyimide also has excellent electrical properties. 2L flexible copper-clad laminate

In addition to the advantages of being thin, light, and flexible, FCCL films based on polyimide also have excellent electrical, thermal, and heat resistance properties. Its low dielectric constant (DK) enables rapid transmission of electrical signals. Good thermal performance makes the components easy to cool. A higher glass transition temperature (Tg) allows the component to operate well at higher temperatures. Due to the fact that most of FCCL's products are provided to users in the form of continuous rolls, using FCCL in printed circuit board production is beneficial for achieving automated continuous production of FPC and continuous surface mounting of components on FPC.

2L FCCL is used for advanced soft board manufacturing, such as soft hard boards, COFs, etc.

The composition of flexible copper-clad laminates mainly includes three types of materials:

Insulation base film material:Flexible copper-clad laminateThe insulation base film materials include polyester (PET) film, polyimide (PI) film, polyester imide film, fluorocarbon ethylene film, amide fiber paper, polybutylene terephthalate film, etc. There are polyester film (PET film) and polyimide film (PI film).

Metal conductor foil: Metal conductor foil is a conductor material for flexible copper-clad laminates, including copper foil (ordinary)Electrolytic copper foilHigh ductility electrolytic copper foil, rolled copper foil, aluminum foil, and copper beryllium alloy foil. Most copper foils are used, including electrolytic copper foil (ED) and rolled copper foil (RA).

Adhesive: Adhesive is an important component of three-layer flexible copper-clad laminates, which directly affects the product performance and quality of flexible copper-clad laminates. The adhesives used for flexible copper-clad laminates mainly include polyester adhesives, acrylic adhesives, epoxy or modified epoxy adhesives, polyimide adhesives, phenolic butyral adhesives, etc. In the three-layer flexible copper-clad laminate industry, adhesives are mainly divided into acrylic adhesives and epoxy resin adhesives.
