  • DETAILED DESCRIPTION
  • The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.
  • Referring to FIG. 2 and FIG. 3, an innovative end cap for IC trays of a first embodiment of the present application is illustrated, which can be used to place, store and transport semiconductors, micro-electronic chips and silicon wafers, and so on. The end cap of this embodiment comprises a bottom 1 and side walls 2 extending upward from the bottom 1, and defines a tray-accommodating space. The end cap of this embodiment comprises a plurality of buffering ribs on touchable surfaces thereof.
  • Specifically, the buffering ribs include a plurality of primary buffering ribs 31, secondary buffering ribs 32, and a plurality of tertiary buffering ribs 33. The primary buffering ribs 31 are protruded from the outer surface of the side walls 2, being strip-shaped or curve-shaped. The primary buffering ribs 31 can be parallel to each other or not. Upper edges of the primary buffering ribs 31 can be as high as an upper edge of the corresponding side wall 2, or higher or lower than the upper edge of the corresponding side wall 2. Lower edges of the primary buffering ribs 31 are as low as or protruded out of the outer surface of the bottom 1. In the first embodiment, the cross-sections of the primary buffering ribs 31 can be of various shapes, such as circle, polygon, etc. In this embodiment, the cross-sections of the primary buffering ribs 31 are in shape of square. The secondary buffering ribs 32 are respectively protruded from the outer corners of the side walls 2. The tertiary buffering ribs 33 are protruded from the inner surface and the two ends of the bottom 1.
  • In the first embodiment, the buffering ribs arranged on the end cap can fully absorb, disperse and transfer the impact energy generated during testing, storage, collision and shock of the trays which accommodate precision semiconductor components therein, and increase impact strength and anti-dropping damage ability of the end cap. Therefore, the end cap with the buffering ribs can not only protect the trays and extend the service lifetime of the trays, but also give better protection to the precision semiconductor components in the trays. Summarily, the end cap for tray of the embodiment is simple in structure but practical in use.
  • Another method to enhance the anti-impact ability of the end cap for IC trays is that a plurality of buffering grooves is defined in the inner surface of the end cap. The buffering grooves have three types. Type one is the buffering grooves 41 and Type two is the buffering grooves 42. Type one of buffer grooves 41 is respectively defined at the junctions of the side walls 2 and dented from the inner surfaces of the sidewalls 2. Type two of the buffering grooves 42 are defined in the bottom 1, and dented from the inner surface of the bottom 1.
  • Referring to FIG. 4 and FIG. 5, an innovative end cap for IC trays of a second embodiment of the present application is illustrated. The end cap in the second embodiment is similar to the end cap in the first embodiment. The main difference of the end cap in the second embodiment from the end cap in the first embodiment is described in detail as follows. In the second embodiment, the primary buffering ribs 31′ are different in shape comparing with the primary buffering ribs 31, and the secondary buffering ribs 32′ are different in shape comparing with the secondary buffering ribs 32. In the second embodiment, cross-sections of the primary buffering ribs 31′ and the secondary buffering ribs 32′ are curved, such as in shape of semi-circle or sinusoidal wave. The primary buffering ribs 31′ each are of arc transition to the corresponding side wall 2. Additionally, the bottom ends of the primary buffering ribs 31′ are protruded out of the outer surface of the bottom 1′, and the protruded parts are connected to the outer surface of the bottom 1′ through a cambered surface. Furthermore, in the second embodiment, the buffering grooves have Type three of the buffering grooves 43. Type three of the buffering grooves 43 is defined in the side walls 2′, and dented from the inner surfaces of the side walls 2′.
  • Referring to FIG. 6 and FIG. 7, an innovative end cap for trays of a third embodiment of the present application is illustrated. The end cap in the third embodiment is similar to the end cap in the second embodiment. The main difference of the end cap in the third embodiment from the end cap in the second embodiment is described in detail as follows. In the third embodiment, bottom ribs 34 are placed on the outer surface of the bottom 1′ to connect bottom edges of the primary buffering ribs 31′. The bottom ribs 34 are protruded from the outer surface of the bottom 1′, and connected to the outer surface of the bottom 1′ through a cambered surface.
  • Understandably, the buffering ribs and the buffering grooves arranged on the side walls, bottom and the junctions of the side walls, can greatly improve the mechanical strength and anti-impact ability of the end cap. In other embodiments, the buffering ribs and the buffering grooves can be mutually combined or exchanged according to the practical requirements, for the purpose of fully absorbing the external impact stress exerted on the tray and reinforcing the strength of the end cap.
  • Compared FIG. 8 with FIG. 1, the end cap with a plurality of buffering ribs and buffering grooves on the side walls, bottom and junctions of the side walls, would not affect the actual volume of the end cap and therefore the innovative end cap can not only be used in the trays with high impact requirements, but also replace the traditional end cap in the normal application areas of trays. The end caps B′ disclosed in the second embodiment are exemplarily installed at opposite sides of the stacked trays A, for being stored and transported together with the stacked trays A. It is can be seen that the end cap of this application is in the same usage for package the trays, but its impact resistance has enhanced greatly.
  • While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
