Abstract:
A tray for ball grid array (BGA) semiconductor packages, with a surface of a BGA semiconductor package being defined with a ball-implanting area where a plurality of solder balls are array-arranged and a non-ball-implanting area free of the solder balls, the tray comprising:a body having an upper surface and a lower surface opposed to the upper surface, the upper surface being formed with a plurality of downwardly recessed cavities, for allowing the semiconductor packages to be received in the recessed cavities with the surfaces of the semiconductor packages having the solder balls facing toward bottom surfaces of the recessed cavities; and at least a protruding portion formed on the bottom surface of each of the recessed cavities, and corresponding in position to the non-ball-implanting area of the surface of the corresponding semiconductor package, so as to allow the protruding portion to support the semiconductor package received in the corresponding recessed cavity.
