Abstract: The present invention discloses a calibration standard for use in a CCD or laser lead scanner for the measurement of lead configurations in an IC package by selectively making three leads with one on three of the four sides of the package at least 0.03 mm longer than the remaining leads such that a consistent calibration plane, i.e., seating plane, is obtained by the lead scanner such that the scanner can be calibrated for making accurate measurements. The utilization of the present invention calibration standard greatly improves the accuracy of measurements made by a CCD or laser lead scanner such that a repair and rework rate of up to 30% that is normally achieved by a conventional standard can be drastically reduced.
