What are the categories of PCB boards (pcb board manufacturer china)?
According to the CCL, they can be divided into rigid copper clad laminate and flexible copper clad laminate.
Usually rigid copper clad laminates are intermittently laminated. Flexible copper clad laminates are heavily used to form copper foil on polyimide or polyester films. The finished product is soft and has excellent folding resistance.
According to different insulation materials and structures, according to different insulation materials and structures, they can be divided into organic resin CCL, metal base (core) copper clad plate and ceramic base copper clad laminate.
Metal clad copper clad plate is usually composed of three parts: metal substrate, insulating medium and conductive layer (usually copper foil). One or both surfaces of a metal substrate to be chemically or electrochemically treated are coated with an insulating dielectric layer and a copper foil, which is compounded by hot pressing.
