ABSTRACT:
Bodies (22) containing bonding material are applied in a substantially simultaneous manner to each of an array of bonding sites (18). A member (50) holds the bodies (22) in an array corresponding to the array of bonding sites (18). A pickup head (40) holds an array of pickup pins (42) such that pickup ends thereof correspond to the array of bodies (22) and sites (18). A mechanism (31) manipulates the head (40) and the array of pins (42) in steps, to substantially simultaneously engage each of the bodies (22) in the member (50) with a corresponding pickup end of a pin (42), to substantially simultaneously contact each of the bodies (22) to a corresponding bonding site (18) and to substantially simultaneously disengage the pins (42) from the bodies (22). In a preferred embodiment, the bodies (22) contain solder which is readily conductive and frictionally engageable by pressure of the pins (42) upon the bodies (22).
