摘要： A PCB comprising a substrate, at least one circuit layer and at least one insulating layer, characterized in that the PCB further comprises at least one embedded functional material such as a PTC, and NTC and ZTC material. If the PTC material is applied in the present invention, a normal resistance of the present invention will be substantially smaller than that of the conventional PTC protection apparatus since the area of the PTC material of the present invention is larger than that of the conventional PTC protection apparatus. Moreover, through an electrically conductive hole, an upper electrode and a lower electrode respectively lying on top and bottom surfaces of the functional material are respectively connected with an apparatus mounted on a surface of the PCB to form a conductive circuit. Thus, at least one over-current protection apparatus which is usually mounted on the surface of the PCB is eliminated, and the surface utilization rate of the PCB is improved.
