Flexible Copper Clad Laminate (FCCL), also known as Flexible Copper Clad Laminate, Flexible Copper Clad Laminate, or Flexible Copper Clad Laminate, is the processing substrate for Flexible Printed Circuit Board (FPC).
1. Classification
Soft copper foil substrates (FCCL) can be divided into two categories: traditional three-layer soft plate substrates with adhesive dosage forms (3L FCCL) and new two-layer soft plate substrates without adhesive dosage forms (2L FCCL).
It is composed of a flexible insulation base film and metal foil, and is composed of three different materials: copper foil, thin film, and adhesive. The flexible copper clad plate is called a three-layer flexible copper clad plate (referred to as "3L-FCCL"). Flexible copper clad plates without adhesive are called two-layer flexible copper clad plates (referred to as "2L-FCCL").
Because the manufacturing methods of these two types of soft copper foil substrates are different, the material properties of the two types of substrates are also different. In terms of application, the application product projects of the two types of FCCLs are different. 3L-FCCL is applied to bulk soft board products, while 2L FCCL is applied to higher-order soft board manufacturing, such as soft and hard boards, COF, etc. Due to the high price of 2L FCCL and insufficient production capacity to meet the demand for higher-order soft boards, many domestic and foreign manufacturers have invested in the production of 2L FCCL, but there are still problems of slow output speed and low yield.
2. Product composition
The composition of flexible copper clad plate mainly includes three types of materials: insulation substrate material: the insulation substrate material used for flexible copper clad plate includes polyester (PET) film, polyimide (PI) film, polyimide film, fluorocarbon ethylene film, amide fiber paper, polybutene phthalate film, etc. Among them, polyester film (PET film) and polyimide film (PI film) are currently the most widely used.
Metal conductor foil
Metal conductor foil is a conductor material used for flexible copper clad laminates, including copper foil (ordinary electrolytic copper foil, high ductility electrolytic copper foil, rolled copper foil), aluminum foil, and copper beryllium alloy foil. 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 flexible copper clad laminate, which directly affects the product performance and quality of flexible copper clad laminate. The main adhesives used for flexible copper clad panels include polyester adhesives, acrylic adhesives, epoxy or modified epoxy adhesives, polyimide adhesives, phenolic butyraldehyde adhesives, etc. In the three-layer flexible copper clad panel industry, adhesives are mainly divided into two schools: acrylic adhesives and epoxy adhesives.
