Method of and apparatus for mounting electric components

In an apparatus for feeding components for mounting on a circuit board and having contacts along opposite ends and sides between said opposite ends, the combination of:

• means carrying a plurality of successive suction nozzles and movable along a predetermined path in synchronism with each other, and moving means for moving said carrying means intermittently past a component receiving station and a succession of stations toward a component mounting station where components are to be mounted on a circuit board and for stopping said carrying means for positioning a nozzle at said stations;
• rectification and electrical testing means at one of said stations between said component receiving station and said component mounting station and having a pair of spaced opposed rectifying and testing fingers movable toward and away from each other in a first direction, said rectifying and testing fingers having electric contact members on the opposed ends thereof which are at least as long as the component contacts are wide and with contact surfaces corresponding to the surface of the component contact surfaces, and having a pair of spaced opposed rectifying fingers movable toward and away from each other in a second direction perpendicular to said first direction along a line midway between said rectifying and testing fingers and with contact surfaces corresponding to the side surfaces of the components, the position where said line intersects a further line between said rectifying and said testing fingers corresponding to a position along said predetermined path where said nozzles are stopped, and means for moving the respective fingers toward and away from each other;
• and
• means for supplying a test current through said electric contact members.
