Abstract
A circuit board has a main board with a base material of insulating material, at least one metal base copper clad laminate, and each metal base copper clad laminate is provided with at least one component and a pin connected with the main board. The circuit board and the driving power supply with the circuit board have simple structure and low manufacturing cost, and are convenient for automatic manufacturing. The power device can be directly mounted on the metal substrate through the automation equipment, so that the metal substrate can realize the function of the heat sink, thereby improving the production efficiency and reducing the process quality hidden danger; at the same time, the grounding problem of the metal substrate is solved, and the EMC problem is avoided.
