Abstract
A semiconductor device carrier tape with image sensor detectable dimples is disclosed. The dimpled carrier tape is formed of a flexible strip of material. A plurality of pockets are disposed spaced apart along the length of the flexible strip of material. Each pocket is configured to hold a semiconductor device. A dimple is formed in each of the plurality of pockets where each dimple has a peripheral edge and a bottom surface. Detection of the dimple by an image sensor facilitates alignment of a semiconductor device with the pocket and precise placement of the semiconductor device in the pocket.
