  Classification of PCB copper clad laminates.IGBT module PCB company(图1)

  1. Classification according to mechanical properties-CCL can be single CCL and compound CCL. Independent copper clad laminate is a kind of copper clad laminate that is not easy to bend and has a certain degree of flexibility. The surface copper clad laminate (CCL) is composed of reinforced materials, and the film is covered with love copper foil or rolled copper foil. The bending, it facilitates the whole of the electronics. The changes that can be brought about by the machinery used are mainly adjusted by the resin and the ingredients.

  2. Classification according to the reinforcement materials used-the use of a certain reinforcement material, attached to the copper plate is based on a material method, the most common classification at present.

  3. According to the thickness of copper clad, it can be reduced to thick and thin plates. IPC thickness: except for thin plates with copper thickness less than 0.5mm.

  4. According to different insulation materials and structures-it can be divided into organic resin-based copper clad laminate, metal-based core copper clad laminate and ceramic-based copper clad laminate.

  5. According to the insulating resin used in the copper clad laminate-use a certain resin resin copper clad laminate, such as epoxy resin copper clad laminate, polyester resin copper clad laminate and resin resin copper clad laminate.
