Stackable tray for integrated circuit chips

A tray for integrated circuit chips comprising:

• a plurality of storage pockets, said storage pockets having a center and being bounded by first and second pairs of diagonally opposed corners, each of said diagonally opposed corners including support elements;
• said support elements including ledges to stabilize integrated circuit chips in a direction perpendicular to the tray;
• said ledges at said first pair of diagonally opposed corners including ridges which are inwardly offset, said ridges of said first pair being spaced a first distance from said center of said storage pocket so as to extend into said storage pocket to stabilize a first pair of diagonally opposed corners of the integrated circuit chip within said storage pocket in directions parallel to the tray;
• said ledges at said second pair of diagonally opposed corners including ridges which are outwardly offset, said ridges of said second pair being spaced a second distance from said center of said storage pocket, said second distance being greater than said first distance, so as to be free of contact with a second pair of diagonally opposed corners of the integrated circuit chip within the storage pocket and to extend into adjacent storage pockets thereby forming ridges of said first pair of diagonally opposed corners of adjacent storage pockets.
