Abstract:
1. A tray for storing a semiconductor device of a ball grid array type, the semiconductor device having opposing sides and a bottom surface including a plurality of solder balls protruding from the bottom surface along peripheral edges of the semiconductor device, the tray comprising: a pocket formed in the tray for holding the semiconductor device, the pocket comprises sidewalls having an upper portion and a lower portion, and a shelf portion located therebetween, the shelf portion having substantially horizontal upper and lower surfaces and an inner edge comprising a vertical wall located therebetween, wherein the shelf portion extends horizontally inwardly from the upper portion, the shelf portion configured to receive a portion of the peripheral edges of the semiconductor device; and a notch comprising the lower portion of the sidewalls of the pocket and the lower surface of the shelf, the lower portion of the sidewalls descending substantially vertically from the lower surface of the shelf such that the notch is formed beneath the shelf portion, wherein the notch is spaced apart from the plurality of solder balls along the peripheral edges of the semiconductor device when one of the opposing sides of the semiconductor device abuts the upper portion of the sidewalls of the pocket.
