Carrier for holding microelectronic devices
One embodiment is a carrier for holding devices that includes a tray having one or more sites in which a device may be held, and a frame resiliently coupled to the tray so the tray is movable with respect to the frame.
1. A carrier for holding microelectronic devices comprises:
a tray having one or more sites adapted to hold a microelectronic device, the tray including a seal band that encircles the sites to provide a top sealing surface; and
a frame resiliently coupled to the tray so the tray is movable with respect to the frame;
wherein: the frame is resiliently coupled to the tray by two or more springs coupled to the frame and the tray, the two or more springs are flat springs, and the two or more flat springs are serpentine springs.
2. The carrier of claim 1 wherein the frame includes an opening in which the tray may be disposed, the opening is in a plane and the tray is movable in a direction perpendicular to the plane.
3. The carrier of claim 2 wherein a portion of the frame lies in the plane.
4. The carrier of claim 3 wherein a portion of one or more edges of the frame are bent out of the plane.
5. A carrier for holding microelectronic devices comprises:
a tray having one or more sites adapted to hold a microelectronic device, the tray including a seal band that encircles the sites to provide a top sealing surface; and
a frame resiliently coupled to the tray so the tray is movable with respect to the frame;
wherein the tray is comprised of a metal.
6. A frame for a carrier that holds a tray of microelectronic devices comprises:
a first band surrounding an opening;
a second band disposed in the opening and adapted to be coupled to the tray;
two or more springs coupled to the first band and the second band so that the second band is movable relative to the opening;
wherein:
the first band includes one or more surfaces that lie in a plane and are adapted to slidably contact two or more transport rails, the opening lies in the plane,
the first band is planar, and
each of the springs is a serpentine flat spring coupled between the first band and the second band.
