Abstract
Abstract The invention is directed to a method and apparatus for handling a component having a body and one or more members protruding therefrom, such that the protruding members are put in proper, mating registration with corresponding holes of a substrate or the like. The components are handled during transport and insertion by gripping of the bodies thereof, and the method and apparatus of the invention compensates for any offset in X, Y, and θ between the profile of the body and a particular pattern or location of the protruding members relative to the profile of the body.
