Factory Cheap Hot Calendered Copper Foil - 2L Flexible Copper Clad Laminate – CIVEN

Product Introduction

In addition to the advantages of thin, light and flexible, FCCL with polyimide based film also has excellent electrical properties, thermal properties, heat resistance characteristics. Its low dielectric constant (DK) makes electrical signals transmit rapidly. Good thermal performance makes the components easy to cool down. The higher glass transition temperature (Tg) allows the components to operate well at higher temperatures. Since most of the products of FCCL are provided to users in continuous roll form, therefore, the use of FCCL in the production of printed circuit boards is beneficial to the realization of automatic continuous production of FPC and the continuous surface installation of components on FPC.

2L FCCL is used in higher-order soft plate manufacturing, such as hard and soft plate, COF, etc.

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

Insulating base film materials: the insulating base film materials for flexible copper clad laminates include polyester (PET) film, polyimide (PI) film, polyester imide film, fluorocarbon ethylene film, amido fiber paper, polybutene p-Phthalate film, etc. Among them, the most widely used are polyester film (PET film) and polyimide film (PI film).

Metal conductor foil: metal conductor foil is a conductor material for flexible copper clad laminate, including copper foil (ordinary electrolytic copper foil, high ductility electrolytic copper foil, calendered copper foil), aluminum foil and copper beryllium alloy foil. Most of them use copper foil, including electrolytic copper foil (ED) and calendered copper foil (RA).

Adhesive: adhesive is an important part of three-layer flexible copper clad laminate, which directly affects the product performance and quality of flexible copper clad laminate. 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 adhesives.
