Here are two fine examples of third optical inspection systems when such systems were at their zenith. Used in assembly to accept, rework or reject wire bonds in un-lidded packages prior to sealing, the 3rd Op station was both a critical customer satisfaction point as well as a critical quality control point in the manufacturing line.

These ASM/AAL systems were semi-automated; an inspector was still needed to view the bonds, decide their status and enter the results manually into the keyboard at the right. If the packages were acceptable, a good operator could inspect about 400 units per hour. If she needed to enter, reject, or rework codes, the rate dropped dramatically while labor rates accelerated. Hence it was no accident that early line managers hated to gather data and fought it furiously until visual inspection machines became fully automatic and computers came into play for data collection.

These two systems are also fine examples of the development and evolution of in-line systems as they could mate with competitor’s systems that provided lid bonding after rework.
