Surface mount placement machines require the correct part be placed at each feeder for a board to be correctly assembled. Parts typically come on reels that are placed on the feeder by a human being. The wrong reel may be placed on the feeder because the human misreads the part number, the feeders may be swapped before being placed on the machine, the supplier of the reel mislabeled the reel, or an incorrect bar code was placed on the reel at Motorola. As a result, boards with incorrect parts must be either scrapped completely or washed off and reworked if caught before the reflow process. This invention attempts to address all these problems.
