According to different insulation of copper clad laminates, copper clad laminates can be divided into two types: rigid copper clad laminates and flexible copper clad laminates. Rigid copper clad laminate The material and its structure can be divided into organic resin copper clad laminate, metal base (core) copper clad laminate and ceramic base clad copper clad. According to the thickness of the copper clad plate, it can be divided into a conventional plate and a thin plate.
According to the reinforcement materials used in the CCL, it can be divided into electronic fiberglass cloth-based copper clad laminates, paper-based copper clad laminates and composite clad copper clad laminates. According to the insulating resin used for the copper clad laminate, a certain resin is called a resin copper clad laminate. Such as epoxy resin copper clad laminate, polyester resin copper clad laminate and cyanate resin copper clad laminate and so on. In addition, there are special rigid copper clad laminates according to the flame retardant grade and some special properties. Flexible copper clad laminate At present, flexible copper clad laminates are classified into polyester film type (flame retardant and non-flame retardant), polyimide film type (flame retardant, non-flame retardant, two-layer method and three-layer method) and extremely thin electronic fiberglass cloth. Three types.
