Abstract

See full text

A method for manufacturing a semiconductor package is proposed. A circuit board with a circuit layer on at least one surface thereof is provided. The circuit board has at least one free area, and the circuit layer has a plurality of electrically connecting pads distributed on the periphery of the free area. A metal protecting layer is plated on the electrically connecting pads by non-plating line. The free area is removed, to form a cavity penetrating the circuit board. The present invention prevents burrs which may otherwise form on the periphery of a cavity, to increase the yield and throughput.
