Akaflex KCL Laminate
KCL is a two or three layer laminate material. It is composed of a polyimide film, with a copper foil sheet attached by an adhesive on either side of it. Different thicknesses of both the copper foil and the PI film can be provided. This laminate is also able to withstand up to 150°C; ideal for higher temp needs. KCL is also halogen free and meets UL94V-0.
KDF is a coverlay or bonding film, containing a polyimide film coated with an adhesive on either one side for use with etched circuits, or both sides when used to produce high-grade multilayers. The thickness of both the PI and the adhesive can be adjusted as needed, and all materials are suitable for up to 130°C.
CDF provides excellent bonding of polymer films and connecting rigid components and flexible laminates with a no-flow resin. It consists of an epoxy resin adhesive film that is protected by paper sheets on both sides. At room temperature, CDF isn’t tacky and is flame retardant. Not only does it work well at bonding to polymers, but also to copper foil. The adhesive thickness can be adjusted, and is protected by a silicone treated paper on the front side and polypropylene film on the back.
