Abstract
Apparatus and methods for inserting leads of an electric circuit component into correspondingly arranged holes in a printed wiring board by (a) holding the component by a robotic arm adjacent the board so that its leads contact the board under pressure and are in nominal registration in the X and Y directions, and (b) subjecting the board to the combined effect of two vibrating motions which are respectively directed in these two directions, and of which one is superimposed on the other. These two motions are each controlled in frequency and amplitude and differ from each other in a motion characteristic whereby the leads sweep in two-dimensional patterns over board areas respective to their corresponding holes and centrally including them until the leads substantially exactly register with the holes to become inserted therein by the pressure on the leads.
