1. Field of the Invention
This invention relates generally to containers, such as boxes, and more particularly to containers for transporting semiconductor devices.
2. Description of the Related Art
Semiconductor devices, such as packaged or unpackaged semiconductor chips, frequently require transport from one location to another. Some of these trips are necessary to send the devices to one or more vendors who perform fabrication processes associated with the chips. Others may simply be deliveries to end users or customers. Frequently these semiconductor devices are first placed in a tray of one sort another. The tray is then stacked with others to form a stack of trays. The stack of trays is then strapped together with plastic straps and placed inside of a cardboard box for shipment. The semiconductor devices are sensitive to a variety of conditions associated with the shipping process. For instance, the semiconductor devices are sensitive to compressive forces, shock forces, electrostatic discharge, and sometimes humidity.
One conventional technique to protect conventional tray stacks involves placing the tray stack inside of a bubble bag, which is a plastic bag consisting of bubble wrap. The bubble bag is then surrounded with a layer of bubble sheet on all sides. The stack enclosed in both the bubble bag and bubble sheet is then placed into a conventional cardboard box. This so-called Q-Pack® box has a back panel that is not reinforced against compressive forces. In addition, the Q-Pack® box requires a carbon coating on almost all interior surfaces in order to provide Faraday shielding. Finally, the volume of the box has to be sufficiently large to accommodate the volume of the tray stack plus bubble bag plus the often irregularly shaped bubble sheets.
A conventional variant of the Q-Pack® suitable for so-called “dry packing” where the semiconductor devices are sensitive to humidity involves the placement of the stack and bubble bag combination inside of a hermetically sealed bag that is in turn placed inside of the bubble sheet and then ultimately the box as described above.
Another conventional variant utilizes a box without front or back panel reinforcement. Separate Faraday shield sheets are sandwiched above and below the stack.
The present invention is directed to overcoming or reducing the effects of one or more of the foregoing disadvantages.
SUMMARY OF THE INVENTIONIn accordance with one aspect of the present invention, a box is provided that includes a container. The container has a bottom panel, a front panel, a first side panel, a second side panel, a back panel, a first reinforcement structure adjacent the back panel and the first side panel and a second reinforcement structure adjacent the back panel and the second side panel. The first and second reinforcement structures reinforce the back panel against compressive forces. A lid is coupled to the container.
In accordance with another aspect of the present invention, a box blank is provided that includes plural components foldable into a container. The components include a bottom panel, a front panel, a back panel, a first side panel, a first reinforcement structure coupled to the first side panel, a second side panel and a second reinforcement structure coupled to the second side panel, the first and second reinforcement structures are operable to reinforce the back panel against compressive forces when the container is assembled.
In accordance with another aspect of the present invention, a method of manufacturing is provided that includes fabricating a box blank that has plural components foldable into a container. The components include a bottom panel, a front panel, a back panel, a first side panel, a first reinforcement structure coupled to the first side panel, a second side panel and a second reinforcement structure coupled to the second side panel. The first and second reinforcement structures are operable to reinforce the back panel against compressive forces when the container is assembled.
The foregoing and other advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings in which:
A box blank may be folded into a box suitable to hold multiple semiconductor device transport trays. When assembled, the box blank includes a container with a front panel and a back panel. The box blank includes reinforcement structures for the front and back panels. The reinforcement structures eliminated the need for a bulky bubble sheet wrap. The box can be made smaller than a conventional design and the bubble sheet is unnecessary. Additional details will now be described.

The assembly of the box blank 10 will now be described in conjunction with
With the front panel 100 in the folded position, the back panel 95 is folded about the x axis at the fold line 135 in direction A approximately 90° from the position shown in
At this point, a multistage folding process is performed for each of the reinforcement structures 25 and 30. Beginning first with the reinforcement structure 25, the first folding operation involves folding the combination of the wrap around panel 175 and the narrow fold portion 190 about they axis at the fold line 200 in direction C. Once that fold is made, a second folding operation is performed by folding the wrap around panel 175 relative to the narrow fold portion 190 about the y axis at the fold line 195. This has the effect of bringing the wrap around panel 175, the back panel reinforcement corner 180 and the front panel reinforcement corner 185 down toward the bottom panel 90. As this folding operation takes place, the back panel reinforcement corner 180 is simultaneously folded at the fold lines 217 and 220 about the z axis so that the back panel reinforcement 180 corner assumes the position shown in
The same operation is performed in a mirror-like fashion with regard to the reinforcement structure 30 in that a multi-fold operation is performed that begins with folding the combination of the wrap around panel 265 and the narrow fold portion 275 about they axis at the fold line 280 in direction D and then subsequently folding the wrap around panel 265 relative to the narrow portion 275 about they axis and the fold line 277 in direction D. This folding about the fold line 277 continues and simultaneously the back panel reinforcement corner 267 is folded about the z axis at both the fold lines 300 and 305 and the front panel reinforcement corner 269 is similarly folded albeit in the opposite direction about the z axis at the fold lines 335 and 340 so that the tabs 310 and 350 of the flaps 295 and 330, respectively, may insert into the slots 315 and 355 and the tab 285 of the wrap around panel 265 may insert into the slot 287 in the bottom panel 90. This final position is shown in
The operation to close the lid 20 will now be described. The top panel 35 may be folded about the x axis at the fold line 140 in direction A approximately 180° from the position shown in
