Each of the respective counting labels are arranged to be over a respective pocket of the respective type of IC package tray corresponding to a counting grid when the counting grid is placed over the respective type of IC package tray. In addition, the respective counting labels of the counting grid are numerically ordered according to an order of filling the pockets of the respective type of IC package tray. A chest includes a bottom opening for holding an IC package tray that is partially filled with IC packages. The chest further includes a plurality of slots disposed through the chest with each slot holding a respective one of the counting grids. The chest also includes a plurality of viewing windows through the top of the chest with each viewing window being aligned over a respective one of the predetermined number of rows of pockets of the IC package tray. The counting labels of each of the counting grids does not appear in the viewing windows when each of the counting grids are at a respective hidden position. However, a respective counting grid corresponding to the IC package tray placed at the bottom opening of the chest is pulled to a visible position such that the counting labels on this counting grid are visible through the viewing windows of the chest. Then, a counting label, of the respective counting grid, over a last pocket to be filled within the IC package tray indicates the count of IC packages within the IC package tray placed at the bottom opening of the chest.
