Abstract:
A multilayer printed circuit board providing large current and high power includes an inner circuit laminated structure, a first adding-layer circuit base board, and second adding-layer circuit base board. The inner circuit laminated structure includes at least one first type and second type conductive circuit layer alternately stacked. The first and second type conductive circuit layer are respectively made of first and second type metal layer, the first and second type metal layer have different etching ability. The second adding-layer circuit base board and the first adding-layer circuit base board are formed on opposite surfaces of the inner circuit laminated structure. The first and second adding-layer circuit base boards are electrically connected to the inner circuit laminated structure. The disclosure also provides a method for manufacturing such multilayer printed circuit board.
