Abstract
A dual-purpose carrier tray is specially adapted for packing and shipping either a plurality of ceramic substrates and/or ceramic BGA packages. The carrier tray includes a tray member having a plurality of pockets disposed therein for packing and storing the plurality of ceramic substrates and/or ceramic BGA packages. Semicircularly depressed support members are provided to support only the lower surface adjacent corresponding corners of the plurality of ceramic substrates and/or ceramic BGA packages. A plurality of stand-offs are provided for contactly engaging only the top surface of the plurality of substrates and/or BGA packages adjacent its corners in a lower tray member when stacked so as to retain firmly the substrates and/or BGA packages in the pockets.
Claims7
A dual-purpose carrier tray for packing and shipping of a plurality of ceramic substrates and/or ceramic BGA packages, said carrier tray comprising:
- a rectangularly-shaped tray member being formed of narrow raised lip portions and a recessed portion surrounded on each side by said lip portions;
- said recessed portion having a plurality of pockets disposed therein for packing and storing the plurality of ceramic substrates and/or ceramic BGA packages;
- each of said plurality of pockets being formed of a bottom wall, opposed side walls, and opposed end walls all joined integrally together to the edges of said bottom wall and extending vertically therefrom so as to form a central cavity portion;
- semicircularly depressed corner member support members disposed adjacent the upper free corners formed by said opposed side walls and said opposed end walls of said plurality of pockets for supporting only the lower surface adjacent corresponding corners of said plurality of ceramic substrates and/or ceramic BGA packages;
- and
- said semicircularly depressed corner support members supporting said plurality of ceramic substrates and/or ceramic BGA packages so that the bottom surfaces thereof are suspended freely above said bottom wall of said plurality of pockets and are aligned over said central cavity portion;
- a plurality of stand-offs disposed on the lower surface of said bottom wall of said pockets adjacent its corners for contactly engaging only the top surface of said plurality of substrates and/or BGA packages adjacent its corners in a lower tray member when stacked and
- said plurality of stand-offs providing clearance areas between the lower surface of said bottom wall of said plurality of pockets on an upper tray member and the top surface of said plurality of substrates and/or BGA packages,
- whereby said plurality of substrates and/or BGA packages are sandwiched between said plurality of stand-offs of an upper tray member and said semicircularly depressed corner support members of a lower tray member when stacked so as to retain firmly said substrates and/or BGA packages in said pockets.
