  • Patent number: 5054704
    Abstract: A combination of a length of component carrier tape and a reel having a hub about which the component carrier tape is helically level wound in layers with the wraps of carrier tape in each layer being disposed edge to edge so that those wraps are displaced axially from each other by the width of the carrier tape, and with the opposite edges of wraps of carrier tape in successive layers being angled in opposite directions with respect to the axis of the hub. The peripheral surface of the hub has a minimum diameter "D" in millimeters determined by the formula: ##EQU1## where "W" is the width of the carrier tape in millimeters so that the component carrier tape should meet an industry camber specification despite cold flow which will occur in transition portions of the carrier tape between the layers.
