Abstract:
A method for manufacturing a semiconductor package using a reel-deployable printed circuit board, comprising:(A) forming a printed circuit board comprising an elongated, flexible base board having opposite edges and a slit cut through it, the slit defining a unit board within the flexible base board that is connected to the base board and pivotable relative to it by means of a connection bar extending between the two boards in a direction perpendicular to the long direction of the base board, the unit board having top and bottom surfaces, a bonding pad on the top surface, a contact on the bottom surface, and a via hole electrically connecting the contact with the bonding pad;(B) attaching a semiconductor chip to the top surface of the unit board;(C) electrically connecting the semiconductor chip to the bonding pad; and,(D) encapsulating the top surface of the unit board with an encapsulant in a region including the semiconductor chip and the bonding pad.
