A tape and reel inspection system is provided with OCR testing of devices,
network retrieval of device lot information, and automatic teaching of
image patterns. Each device lot is typically accompanied by a travel
sheet, which includes a history for the device lot. The travel sheet may
include a bar code to allow the system to receive the device lot number
while reducing the possibility of human error. The system performs OCR on
a first device. The system communicates with a database to obtain lot
information. The system combines lot information and package information
to form marking information. The system then compares the contents of the
markings with line information obtained from the marking information.
Once a first device passes the OCR test, the system trains an image of
the first device. Image training may be done automatically without
intervention from the operator. If a subsequent device fails the image
test, the inspection system automatically performs OCR on the failed
device.
