The method sets forth searching and finding insertion locations, thereby increasing the reliability of robot assembly of PC (printed circuit) cards. The tolerances involved in the process of inserting components into PC cards are often close to the combined repeatability of the robot, feeders and fixturing. Hence, it is not surprising that a robot often misses the insertion on the first attempt. The following describes one solution to this situation which has been successfully implemented on a robot. Three pieces of hardware are required for this method. First, the vacuum chuck, which serves as the end of arm tooling, is spring-loaded so that it has about 0.1 inch of free travel.
