摘要:A circuit board for semiconductor package is designed to provide a completegrounding with corresponding equipment in the manufacture of the semiconductor

package based on a circuit board, thereby preventing a breakdown of the circuit board orsemiconductor chip caused by electrostatic charges. The printed circuit board for

semiconductor package includes: a resinous substrate; a chip mounting region formed onthe top surface of the resinous substrate for mounting a semiconductor chip thereon; aplurality of fine circuit patterns radially disposed in the circumference of the chipmounting region and extending to the edge of the chip mounting region; a plurality ofball lands formed in an array on the bottom surface of the resinous substrate, to befused to conductive balls; a conductive via hole connecting the circuit patterns on the topsurface of the resinous substrate to the ball lands on the bottom surface of the resinoussubstrate; a cover coat applied to the top and bottom surfaces of the resinous substrateto protect the circuit patterns from an external environment and make the ball landsopen to the exterior; and a means for removing electrostatic charges provided at theedge of the substrate and connected to the plural circuit patterns to removeelectrostatic charges in the manufacture of semiconductors.
