ABSTRACT:
Apparatus for the bonding of electrical precious metal contacts to the conductor terminations of printed wiring circuit boards. Featured is a rotatable wheel mechanism which, while it is loaded with a contact stock segment at one point on its periphery, at the same time deposits and bonds a previously loaded contact segment to a printed wiring board at an opposite point on its periphery. The wheel incorporates an internally mounted, radially aligned plunger having a magnet at each of its outer ends. With the plunger aligned vertically, the wheel is loaded at the top from a reel-fed supply of contact stock, a segment of which is sheared off by a downward movement of a punch blade which also deposits the severed contact segment on the upper magnet where it is retained by magnetic flux acting on a nickel layer of the segment. The punch continues its downward travel to deposit a previously loaded segment retained by the lower magnet to its ultimate location on the wiring board. Upon the restoration of the punch and blade, the wheel is rotated 180.degree. to repeat the loading-bonding cycle.
